USE INSTRUCTION MANUAL
FOR MATERIALS HANDLING
A two person fall protection anchorage device for use on steel structures
covered by grid mesh, allowing workers to work directly below the platform.
This manual should be used as part of an employee training program.
DESCRIPTION:
The Gridmesh Anchor (GMA) is designed to be a part of a hauling system for use on suitable steel
structures that are covered by trafcable gridmesh. This application might typically be in processing plants,
on oil rigs and other applications in chemical plants, mining and oil & gas industries.
Gridmesh anchors do not place any load on the trafcable areas of the walkway in a way that would
damage it. Issues such as sagging or bending by placing higher loads is avoided as the GMA design will
direct any impact loads directly into the structure to which the mesh is attached. This ensures that the GMA
will place no more load than would otherwise be directed under trafc conditions or if using alternative
means of access such as rope access systems.
WARNING: This product is part of a hauling system for materials handling. The user must follow
the manufacturer’s instructions for each component of the system. These instructions must be
provided to the user of this equipment. The user must read and understand these instructions
before using this equipment. Manufacturer’s instructions must be followed for proper use and
maintenance of this equipment. Alterations or misuse of this product or failure to follow instructions
may result in serious injury or death.
IMPORTANT: If you have questions on the use, care, or suitability of this equipment for your
application, contact Gridmesh Anchor.

1.0 Application
Purpose: The Gridmesh Anchor is designed to allow a worker to connect a Chain block/block or
tackle device in a location directly below a walkway or trafcable area covered by Gridmesh.
The GMA provides superior installation time and safety than traditional methods of setting an
anchorage for this style of application. The risk of a fall by a rope access technician to get to a
place to install a beam anchors/clamp is removed and the requirement to use an EWP is also
negated. The device can be installed in under 5 minutes with two people.
The Gridmesh Anchor concept may also be used as an attachment point for fall protection and
rescue - see user manual for fall protection for more information. Only ever use the specic
Gridmesh Anchor for materials handling for this purpose - if fall protection is required, use
product models GA01 or GA02.
Standards: The Gridmesh Anchor device/kit has been tested in accordance with AS1418 as a
mobile crane device up to 1.2 tonne WLL. The slings used are individually tested and certied
to AS1666.
Training: This equipment is intended to be used by persons trained in its correct application and
use. It is the responsibility of users to ensure that they are familiar with these instructions and
are trained in the correct care and use of this equipment. Users must be aware of the operating
characteristics, application limits, and the consequences of improper use.
2.0 Limitations & Requirements
Installation Location: The Gridmesh Anchor must be positioned on a gridmesh structure in
such a way as the load bearing feet of the device rest over structure supporting/holding up the
mesh. If there is any doubt about the potential for the structure to sustain a fall arrest load, a
qualied person should be consulted to verify the structural adequacy prior to use.
NOTE: Load Limit - the maximum weight of the equipment to be hauled using this
device is 1.2 metric tonnes.
Free Fall / Swing Fall: Gridmesh Anchor recommends that during the hauling process that
care be taken to-avoid the suspended load being dropped in a free-fall situation or being allowed
to swing and come into contact with structures, people or other objects. In order to avoid this
possibility, place the load as directly as possible below the anchor location and secure a guide
rope to the rope to manage the potential for swing in the load as hauling commences.
Exclusion Zones: Always establish exclusion zones around the load hauling areas. Exclusions
zones require a temporary barricade to be erected to prevent the public or other workers for
walking unintentionally below a suspended load. The person hauling the load using the block &
tackle or chain block should also ensure they do not stand below the load drop zone and that
they remain clear of the suspended load in the instance it may become accidentally dislodged,
or there is a failure in the hauling equipment. A falling load may result in serious injury or death
for any person struck by a fall load.
Physical and Environmental hazards: A risk assessment should be undertaken prior to
installing any GMA product. The Gridmesh Anchor and any attaching hauling systems must be
positioned in a way that reduces the risk of a load colliding or impacting them in the event of a
fall. For example protrusions, sharp edges, machinery or other items that may be located in the
area a fall may occur should be cleared or precautions taken to prevent collision prior to use.
i
Compatibility of Components: Unless otherwise noted, Gridmesh Anchor equipment
is designed for use with Gridmesh Anchor approved components and subsystems only.
Substitutions or replacements made with non approved components or subsystems may
jeopardize compatibility of equipment and may affect safety and reliability of the complete
system.
IMPORTANT: Read and follow manufacturer’s instructions for associated components and
subsystems in your hauling system.
Compatibility of Connectors: Connectors are compatible with connecting elements
when they have been designed to work together in such a way that their sizes and shapes
do not cause their gate mechanisms to inadvertently open regardless of how they become
oriented. Contact Gridmesh Anchor if you have any questions about compatibility. Connectors
(hooks, karabiners, and D-rings) must be capable of supporting at least 22.2kN (5,000 lb).
Connectors must be compatible with the anchorage or other system components. Do not use
equipment that is not compatible. Non-compatible connectors may unintentionally disengage.
Connectors must be compatible in size, shape, and strength.
Making Connections: Snap hooks and karabiners used with this equipment must be self-
locking. Ensure all connections are compatible in size, shape and strength. Do not use
equipment that is not compatible. Ensure all connectors are fully closed and locked.
Gridmesh Anchor connectors (snap hooks and karabiners) are designed to be used only as
specied in each product’s user’s instructions. See Figure 3 for examples of inappropriate
connections. Do not connect snap hooks and karabiners:
A. To a D-ring to which another connector is attached.
B. In a manner that would result in a load on the gate.
C. In a false engagement, where features that protrude from the snap hook or karabiner
catch on the anchor, and without visual conrmation seems to be fully engaged to the
anchor point.
D. To each other.
E. By wrapping cable lifeline around anchorage and securing to lifeline.
F. To any object which is shaped or dimensioned such that the snap hook or karabiner will
not close and lock, or that roll-out could occur.
G. In a manner that does not allow the connector to align properly while under load.
i
Figure 2 - Unintentional disengagement Figure 3 - Inappropriate connections
If the connecting element to which a snap hook (shown) or
karabiner attaches is undersized or irregular in shape, a situation
could occur where the connecting element applies a force to
the gate of the snap hook or karabiner. This force may cause
the gate (of either a self-locking or a non-locking snap hook) to
open, allowing the snap hook or karabiner to disengage from the
connecting point.

Assumptions:
1. Maximum oor width = 1200 mm
2. The GMA sits, and is positioned so as to transfer load through 2 beams.
3. All materials are Grade 300 Mpa or better (AS3678 & AS1163)
4. Floor is fully loaded at 2.5 Kpa (typical design load) - Is equivalent to 255 kg per m^2
5. Floor mesh and handrails considered to be approx 50 kg per square metre.
6. A 1.25x factor has been applied to the loads, for error in estimations of operators.
7. It’s assumed the beams are full restrained, buckling has not been considered.
8. 15kN fall arrest anchorage load has been used to one side. This means 2 anchorages can
be used on the same device on either side.
3.0 Installation
Gridmesh Anchor Installation:
A. GMA Assembly (GA03): The Gridmesh Anchor assembly is intended to be used
on steel structure with 1.2m centres, however can be used on narrower structures by
re-orienting the device diagonally (e.g. 900mm or 750mm). The model GMA04 has
additional equipment as second lifting point, however the total haul load MUST NOT
EXCEED 1.2 tonnes.
B. System height/clearance: The Gridmesh Anchor should be located on a structure
where the height above the surrounding work area is sufcient to enable a chain
block / block and tackle to be operated in accordance with user instructions. If there is
insufcient clearance, DO NOT use the device.
C. Evaluate System Location: The location of the Gridmesh Anchor(s) must be
determined by the user. Do not place any potential users at risk during the installation
and operation a completely installed system. Utilise the chart on Page 7 to determine
that the structure is suitable for use.
D. Inspection: Before installing the Gridmesh Anchor on the mesh, both the mesh and its
structure should be visually inspected to conrm that it will hold hauling loads. If there is
any doubt about the ability of the system to sustain the loads, the system should not be
installed. If necessary, a structural engineer should validate the structural integrity of the
component members.
E. Risk assessment: Prior to any job being undertaken, it is recommended that the user
undertake a risk assessment and prepare a safe work method statement (SWMS) to
ensure the equipment use and operation is within the manufacturer guidelines and the
operating requirements of the site.
Steps for Installation:
1. Using the storage bag, carry the Gridmesh
Anchor kit to the desired location. Ideally there
will be a user at the top of the structure to set the
anchorage on the mesh and a user below the
mesh to arrange connection to the equipment
from below.

2. Open the storage bag and lay the GMA base
onto the gridmesh walkway area. Be sure to
align the load points of the GMA onto a location
immediately above the structural members
supporting the walkway. This may require placing
the base diagonally to the direction of the mesh
slots if the distance between the structural
members is less than 1200mm.
3. On structures where there is high wind, ocean
swell or moving equipment, it may be appropriate
to secure the GMA to the structure with rope,
cable ties, maillons or another appropriate
fastening to prevent the GMA from moving.

4. Open the GMA lid and remove the rope tag-line,
wire sling and support beam. Connect the end of
the sling to the rope tag line.
5. Align the GMA such that the location slot for
the GMA sits no more than 150mm from the
supporting structure below the gridmesh.

6. Lower the rope tag line ‘sling rst’ through the
GMA base and the slot in the gridmesh. It may
be necessary to squeeze the eye of the sling so
that it ts through the mesh.
7. Once lowered, the worker below should connect
a chain block or block & tackle to the sling.
They should also ensure that there is sufcient
load line chain available to be connected to the
load once the device is raised into position.
8. Haul the sling with chainblock/block & tackle
attached by pulling the rope back through
the gridmesh, such that the end of the sling
protrudes through the gridmesh and the base
of the GMA.
9. Slide the GMA beam end through the sling
and slide into position in the base, such that
the beam can rest into its operating position
within the GMA base. The chain block / block
& tackle is now set for use.

12 13
10. Once the installation is completed, the worker below the GMA will use the chain to lower the
connecting hook to be lowered into place. Use the green webbing tag line provided to secure to the
load to be hauled to minimise the swing / movement of the load as it is hauled using the chainblock.
11. Disassemble by following the steps listed above in reverse.
IMPORTANT: The maximum weight that can hauled and suspended using this device is
1.2 metric tonnes. Ensure that the chainblock / block & tackle assembly being used for
hauling the loads has a WLL of at least 1.5 tonnes and is within current inspection and
certication prior to use.
WARNING: The use of multiple GMA devices requires adequate structure to support the loads
and number of users. Failure to do so could result in structural failure and serious injury or death.

4.0 Operation
WARNING: Do not alter or intentionally misuse this equipment. Consult Gridmesh Anchor when
using this equipment in combination with components or subsystems other than those described
in this manual. Some subsystem and component combinations may interfere with the operation
of this equipment. Use caution when using this equipment around moving machinery, electrical
hazards, chemical hazards, sharp edges, or overhead materials that may fall onto a Gridmesh
Anchor. Failure to heed this warning may result in equipment malfunction, serious injury or death.
WARNING: Safe movement of loads using hauling methods requires training. Ensure you have
obtained the relevant qualications to perform the hauling of goods prior to using this equipment.
Before each use: Inspect the Gridmesh Anchor according to inspection procedures outlined
in Section 5. Do not use this equipment if inspection reveals an unsafe or defective
condition. Plan your use of the Gridmesh Anchor for materials handling prior to exposing
workers to dangerous situations. Consider all factors affecting your safety before using the
Gridmesh Anchor.
• Read and understand all manufacturers’ instructions for each component of the
hauling system. All sub systems are supplied with separate user instructions. Keep
all instructions for future reference.
• Review Section 1.2 and Section 2.0 to ensure system limitations and other
requirements have been met. Review applicable information regarding system
clearance criteria and ensure changes have not been made to the system installation
(i.e. length) that could affect the required clearance for correct use. Do not use the
system if changes are required.
Chain block system components: Inspect all components in accordance with
manufacturer’s instructions. Consult with the user manual for specic details. Check to
ensure that the unit is presently within the service/inspection requirements by viewing the
inspection service tag. Do not use the unit if outside the service life period.
WARNING: A risk of swinging loads is apparent when hauling. Swinging loads may result in
serious damage, personal injury or death if the contact a person or other object. To avoid swinging
loads, locate the load to be hauled as close to a position directly under the Gridmesh Anchor as
possible. Utilise the green webbing line to attach to the load to reduce the risk of swinging during
the hauling process by maintaining a tension on the webbing tag line.
Hazardous Situations: Do not take unnecessary risks, such as reaching too far from the
edge of the working surface. To avoid the risk of a dropped load, work away from directly
under the hauled load.
Sharp edges: Avoid working where the connecting subsystem or other system components
will be in contact with sharp edges or abrade against unprotected sharp edges. If working
around sharp edges is unavoidable, a protective cover must be used to prevent cutting of
the sling, or utilize a specially designed device with sharp-edge protection properties.
System removal: The Gridmesh Anchor should be removed from the structure when it is
no longer required. The steps 1 through 9 in section 4 should be followed in reverse for the
GMA to be removed.

place to install a beam anchors/clamp is removed and the requirement to use an EWP is also
negated. The device can be installed in under 5 minutes with two people.
The Gridmesh Anchor concept may also be used as an attachment point for fall protection and
rescue - see user manual for fall protection for more information. Only ever use the specic
Gridmesh Anchor for materials handling for this purpose - if fall protection is required, use
product models GA01 or GA02.
Standards: The Gridmesh Anchor device/kit has been tested in accordance with AS1418 as a
mobile crane device up to 1.2 tonne WLL. The slings used are individually tested and certied
to AS1666.
Training: This equipment is intended to be used by persons trained in its correct application and
use. It is the responsibility of users to ensure that they are familiar with these instructions and
are trained in the correct care and use of this equipment. Users must be aware of the operating
characteristics, application limits, and the consequences of improper use.
2.0 Limitations & Requirements
Installation Location: The Gridmesh Anchor must be positioned on a gridmesh structure in
such a way as the load bearing feet of the device rest over structure supporting/holding up the
mesh. If there is any doubt about the potential for the structure to sustain a fall arrest load, a
qualied person should be consulted to verify the structural adequacy prior to use.
NOTE: Load Limit - the maximum weight of the equipment to be hauled using this
device is 1.2 metric tonnes.
Free Fall / Swing Fall: Gridmesh Anchor recommends that during the hauling process that
care be taken to-avoid the suspended load being dropped in a free-fall situation or being allowed
to swing and come into contact with structures, people or other objects. In order to avoid this
possibility, place the load as directly as possible below the anchor location and secure a guide
rope to the rope to manage the potential for swing in the load as hauling commences.
Exclusion Zones: Always establish exclusion zones around the load hauling areas. Exclusions
zones require a temporary barricade to be erected to prevent the public or other workers for
walking unintentionally below a suspended load. The person hauling the load using the block &
tackle or chain block should also ensure they do not stand below the load drop zone and that
they remain clear of the suspended load in the instance it may become accidentally dislodged,
or there is a failure in the hauling equipment. A falling load may result in serious injury or death
for any person struck by a fall load.
Physical and Environmental hazards: A risk assessment should be undertaken prior to
installing any GMA product. The Gridmesh Anchor and any attaching hauling systems must be
positioned in a way that reduces the risk of a load colliding or impacting them in the event of a
fall. For example protrusions, sharp edges, machinery or other items that may be located in the
area a fall may occur should be cleared or precautions taken to prevent collision prior to use.
i
Compatibility of Components: Unless otherwise noted, Gridmesh Anchor equipment
is designed for use with Gridmesh Anchor approved components and subsystems only.
Substitutions or replacements made with non approved components or subsystems may
jeopardize compatibility of equipment and may affect safety and reliability of the complete
system.
IMPORTANT: Read and follow manufacturer’s instructions for associated components and
subsystems in your hauling system.
Compatibility of Connectors: Connectors are compatible with connecting elements
when they have been designed to work together in such a way that their sizes and shapes
do not cause their gate mechanisms to inadvertently open regardless of how they become
oriented. Contact Gridmesh Anchor if you have any questions about compatibility. Connectors
(hooks, karabiners, and D-rings) must be capable of supporting at least 22.2kN (5,000 lb).
Connectors must be compatible with the anchorage or other system components. Do not use
equipment that is not compatible. Non-compatible connectors may unintentionally disengage.
Connectors must be compatible in size, shape, and strength.
Making Connections: Snap hooks and karabiners used with this equipment must be self-
locking. Ensure all connections are compatible in size, shape and strength. Do not use
equipment that is not compatible. Ensure all connectors are fully closed and locked.
Gridmesh Anchor connectors (snap hooks and karabiners) are designed to be used only as
specied in each product’s user’s instructions. See Figure 3 for examples of inappropriate
connections. Do not connect snap hooks and karabiners:
A. To a D-ring to which another connector is attached.
B. In a manner that would result in a load on the gate.
C. In a false engagement, where features that protrude from the snap hook or karabiner
catch on the anchor, and without visual conrmation seems to be fully engaged to the
anchor point.
D. To each other.
E. By wrapping cable lifeline around anchorage and securing to lifeline.
F. To any object which is shaped or dimensioned such that the snap hook or karabiner will
not close and lock, or that roll-out could occur.
G. In a manner that does not allow the connector to align properly while under load.
i
Figure 2 - Unintentional disengagement Figure 3 - Inappropriate connections
If the connecting element to which a snap hook (shown) or
karabiner attaches is undersized or irregular in shape, a situation
could occur where the connecting element applies a force to
the gate of the snap hook or karabiner. This force may cause
the gate (of either a self-locking or a non-locking snap hook) to
open, allowing the snap hook or karabiner to disengage from the
connecting point.

Assumptions:
1. Maximum oor width = 1200 mm
2. The GMA sits, and is positioned so as to transfer load through 2 beams.
3. All materials are Grade 300 Mpa or better (AS3678 & AS1163)
4. Floor is fully loaded at 2.5 Kpa (typical design load) - Is equivalent to 255 kg per m^2
5. Floor mesh and handrails considered to be approx 50 kg per square metre.
6. A 1.25x factor has been applied to the loads, for error in estimations of operators.
7. It’s assumed the beams are full restrained, buckling has not been considered.
8. 15kN fall arrest anchorage load has been used to one side. This means 2 anchorages can
be used on the same device on either side.
3.0 Installation
Gridmesh Anchor Installation:
A. GMA Assembly (GA03): The Gridmesh Anchor assembly is intended to be used
on steel structure with 1.2m centres, however can be used on narrower structures by
re-orienting the device diagonally (e.g. 900mm or 750mm). The model GMA04 has
additional equipment as second lifting point, however the total haul load MUST NOT
EXCEED 1.2 tonnes.
B. System height/clearance: The Gridmesh Anchor should be located on a structure
where the height above the surrounding work area is sufcient to enable a chain
block / block and tackle to be operated in accordance with user instructions. If there is
insufcient clearance, DO NOT use the device.
C. Evaluate System Location: The location of the Gridmesh Anchor(s) must be
determined by the user. Do not place any potential users at risk during the installation
and operation a completely installed system. Utilise the chart on Page 7 to determine
that the structure is suitable for use.
D. Inspection: Before installing the Gridmesh Anchor on the mesh, both the mesh and its
structure should be visually inspected to conrm that it will hold hauling loads. If there is
any doubt about the ability of the system to sustain the loads, the system should not be
installed. If necessary, a structural engineer should validate the structural integrity of the
component members.
E. Risk assessment: Prior to any job being undertaken, it is recommended that the user
undertake a risk assessment and prepare a safe work method statement (SWMS) to
ensure the equipment use and operation is within the manufacturer guidelines and the
operating requirements of the site.
Steps for Installation:
1. Using the storage bag, carry the Gridmesh
Anchor kit to the desired location. Ideally there
will be a user at the top of the structure to set the
anchorage on the mesh and a user below the
mesh to arrange connection to the equipment
from below.

98
2. Open the storage bag and lay the GMA base
onto the gridmesh walkway area. Be sure to
align the load points of the GMA onto a location
immediately above the structural members
supporting the walkway. This may require placing
the base diagonally to the direction of the mesh
slots if the distance between the structural
members is less than 1200mm.
3. On structures where there is high wind, ocean
swell or moving equipment, it may be appropriate
to secure the GMA to the structure with rope,
cable ties, maillons or another appropriate
fastening to prevent the GMA from moving.

4. Open the GMA lid and remove the rope tag-line,
wire sling and support beam. Connect the end of
the sling to the rope tag line.
5. Align the GMA such that the location slot for
the GMA sits no more than 150mm from the
supporting structure below the gridmesh.

6. Lower the rope tag line ‘sling rst’ through the
GMA base and the slot in the gridmesh. It may
be necessary to squeeze the eye of the sling so
that it ts through the mesh.
7. Once lowered, the worker below should connect
a chain block or block & tackle to the sling.
They should also ensure that there is sufcient
load line chain available to be connected to the
load once the device is raised into position.
8. Haul the sling with chainblock/block & tackle
attached by pulling the rope back through
the gridmesh, such that the end of the sling
protrudes through the gridmesh and the base
of the GMA.
9. Slide the GMA beam end through the sling
and slide into position in the base, such that
the beam can rest into its operating position
within the GMA base. The chain block / block
& tackle is now set for use.

10. Once the installation is completed, the worker below the GMA will use the chain to lower the
connecting hook to be lowered into place. Use the green webbing tag line provided to secure to the
load to be hauled to minimise the swing / movement of the load as it is hauled using the chainblock.
11. Disassemble by following the steps listed above in reverse.
IMPORTANT: The maximum weight that can hauled and suspended using this device is
1.2 metric tonnes. Ensure that the chainblock / block & tackle assembly being used for
hauling the loads has a WLL of at least 1.5 tonnes and is within current inspection and
certication prior to use.
WARNING: The use of multiple GMA devices requires adequate structure to support the loads
and number of users. Failure to do so could result in structural failure and serious injury or death.

4.0 Operation
WARNING: Do not alter or intentionally misuse this equipment. Consult Gridmesh Anchor when
using this equipment in combination with components or subsystems other than those described
in this manual. Some subsystem and component combinations may interfere with the operation
of this equipment. Use caution when using this equipment around moving machinery, electrical
hazards, chemical hazards, sharp edges, or overhead materials that may fall onto a Gridmesh
Anchor. Failure to heed this warning may result in equipment malfunction, serious injury or death.
WARNING: Safe movement of loads using hauling methods requires training. Ensure you have
obtained the relevant qualications to perform the hauling of goods prior to using this equipment.
Before each use: Inspect the Gridmesh Anchor according to inspection procedures outlined
in Section 5. Do not use this equipment if inspection reveals an unsafe or defective
condition. Plan your use of the Gridmesh Anchor for materials handling prior to exposing
workers to dangerous situations. Consider all factors affecting your safety before using the
Gridmesh Anchor.
• Read and understand all manufacturers’ instructions for each component of the
hauling system. All sub systems are supplied with separate user instructions. Keep
all instructions for future reference.
• Review Section 1.2 and Section 2.0 to ensure system limitations and other
requirements have been met. Review applicable information regarding system
clearance criteria and ensure changes have not been made to the system installation
(i.e. length) that could affect the required clearance for correct use. Do not use the
system if changes are required.
Chain block system components: Inspect all components in accordance with
manufacturer’s instructions. Consult with the user manual for specic details. Check to
ensure that the unit is presently within the service/inspection requirements by viewing the
inspection service tag. Do not use the unit if outside the service life period.
WARNING: A risk of swinging loads is apparent when hauling. Swinging loads may result in
serious damage, personal injury or death if the contact a person or other object. To avoid swinging
loads, locate the load to be hauled as close to a position directly under the Gridmesh Anchor as
possible. Utilise the green webbing line to attach to the load to reduce the risk of swinging during
the hauling process by maintaining a tension on the webbing tag line.
Hazardous Situations: Do not take unnecessary risks, such as reaching too far from the
edge of the working surface. To avoid the risk of a dropped load, work away from directly
under the hauled load.
Sharp edges: Avoid working where the connecting subsystem or other system components
will be in contact with sharp edges or abrade against unprotected sharp edges. If working
around sharp edges is unavoidable, a protective cover must be used to prevent cutting of
the sling, or utilize a specially designed device with sharp-edge protection properties.
System removal: The Gridmesh Anchor should be removed from the structure when it is
no longer required. The steps 1 through 9 in section 4 should be followed in reverse for the
GMA to be removed.
