•How to select and make connections to anchorages and anchorage connectors
•Proper attachment locations and proper attachment methods including compatibility
of connections to reduce the probability of accidental disengagement.
•How to evacuate from a hazardous space.
•What to do after a fall to protect the user from injury, including emergency rescue
planning and execution.
•The consequences of improper use of the equipment and of failure to follow
instructions and training.
Training must be conducted without undue exposure of the trainee to hazards. The effectiveness of
training should be periodically assessed and the need for more training or retraining determined.
2.2. Hazards
WARNING!
Do not use the folding davit unless a qualified person has inspected the workplace and
determined that use of the folding davit is essential and that identified hazards can neither be
eliminated nor exposures to them prevented.
Prior to selecting a folding davit or other personal protective equipment, the user must make a
workplace assessment of hazards and conditions where the equipment is required. Such assessment
must, at a minimum, identify the presence of:
•Abrasive surfaces
•Electrical hazards

COPYRIGHT ©2015, SAYFA SYSTEMS 6 FDIM-01- REV D-DA300- NO INSPECTION 15/09/15
•Moving equipment, materials
•Weather & Climate factors
•Environmental contaminants, Chemicals
•Moving materials, unguarded openings & Unstable/uneven surfaces Slippery surfaces
•Heat-producing operations, Sparks or flames & hot objects
Confined space hazards Foreseeable changes in any of these conditions, taken individually or
collectively, must be identified.
The materials and construction of the folding davit and associated equipment must be
considered in the selection process such that these workplace conditions are suitably addressed
and responded to. The equipment must match the work situation and workplace environmental
factors.
The workplace assessment must identify all paths of intended user movement and all hazards
along such paths. The user must identify the required range of mobility in each hazard zone and
note the location and distance to all obstructions in potential fall paths. Lateral obstructions
which could be contacted in a pendulum fall arrest must be noted. If the folding davit and
mounting base are to be used for personnel-riding system, it must be backed up by a personal
fall arrest system incorporating a shock absorbing Lanyard (SAL). The SAL connecting the user's
harness to the folding davit anchorage connection must be selected so as to satisfactory limit
total fall distance. If the folding davit and mounting base are to be used for confined space entry
operations, the workplace assessment must comply with the requirements of the Confined
Spaces Regulations 1997.
3. DESCRIPTION OF FOLDING DAVIT
3.1. FOLDING DAVIT
The folding davit consists of a Clear coated (can be coloured) 6082 T6 aluminium Vertical CHS
and horizontal SHS connected by a high strength aluminium hinge bracket. It is supported in the
vertical position by the S275 steel mounting base. The hinged bracket design permits folding of
the unit to permit easy transportability when removed from the base. The davit will swivel until
bolted in position which MUST be done before a load is applied, thereby holding the davit in
position for lifting and lowering. There is an eyebolt at the base to provide an anchorage
connector for fall arrest capability. See fig 1. (Part No. DA-300)
3.2. MOUNTING BASE
The mounting base is the means by which the folding davit is attached to a structural anchorage.
The base is permanently secured to the anchorage at floor level by eight (8) chemical fix studs,
16mm diameter, Stainless Steel Grade 8.8 A2. The tube, welded to the base is constructed of
S355; the plates are made from S275 Structural steel. Galvanized to BS EN ISO 1461. A stainless
steel mounting base is available for highly corrosive environments. See Fig2. (Part No. DB150,
DB-250 & DB-350)

3.3. MOUNTING BRACKET FOR WINCH (optional)
Mounting Bracket constructed from 6082 T6 hi strength aluminium, bespoke design to fit your
preferred winch. See Fig 3. (Part No. DAWB-01)
4. FIT FOR PURPOSE
4.1. PURPOSE OF THE FOLDING DAVIT SYSTEM
The primary purpose of the folding davit and mounting base is to provide a means for anchoring
a personnel/materials handling hoist to a structural anchorage and, thus, enable lifting,
lowering, and suspension of personnel and materials from its location above a work space.
Secondly, the folding davit serves as an anchorage connector for a shock absorbing Lanyard
(SAL) providing personal fall arrest capability for a worker connected. The DA300 system is
designed to support a working live load of (136 kg) for personnel (total weight including clothing
and tools) and (272 kg) for materials. The system is designed to support only one person at time
(except for rescue). Use of the folding davit must comply with these User Instructions and is
subject to approval under the user’s safety rules and regulations and by the user's safety
director, supervisor, or a qualified safety engineer. Be certain the selection of the folding davit
and mounting base is suited for the intended use and work environment. If there is any conflict
between these User Instructions and other directives or procedures of the user’s organization,
do not use the folding davit until such conflicts are resolved.

5. INSTALLATION
WARNING!
CAUTION! Installation of the folding davit with mounting base should be performed under the
guidance of a qualified person!
5.1. INSTALLING THE MOUNTING BASE
Begin by selecting a structural anchorage of sufficient strength to support a minimum vertical
load of 21.3KN on the mounting bracket. This load must be applied at any angle which the user's
movement or path may cause.
The structural anchorage must have a flat surface of at least 0.3 m x 0.3 m square on which the
base will rest. The anchorage location should be chosen to allow the folding davit pulley to be
placed directly over the working area. In order to operate the system properly, sufficient
working space must be provided around the davit.
The base is secured to a minimum Concrete structure of 160mm deep using 8No. EPCON C8 M16
Studs 125mm long ISO 3506-1,general overview of fitting: Drill holes to 125mm with 18mm bit,
use compressed air to clear hole, then clean hole with rotary hole brush and again blow out
dust. At 20˚ C fitting time is approx. 15min, curing time 12h. Please see user instructions for
specific data. Torque nuts to 60Nm.

7. SYSTEMS REQUIREMENTS
The folding davit and mounting base are components of multi-component systems. Without
the other necessary components, they serve no useful purpose. The folding davit and mounting
base are primarily intended for material handling and as a personnel riding system backed up by
a personal fall arrest system attached to an eyebolt on the davit arm to base fixing. They may
also be used in rescue and climbing protection systems. In general, however, they are not
intended for restraint and evacuation systems use. In order to clarify the distinctions between
these different systems and combinations of systems, they are briefly described below.
7.1.1.SYSTEM TYPES
Systems are classified according to their intended purposes. There are six classifications of
systems which may be used individually or in combinations. The six basic systems classifications
are:
• Personnel-riding
• Fall Arrest
• Rescue
• Climbing protection
• Restraint
• Evacuation
7.1.2. PERSONNEL SYSTEMS
A personnel-riding system is an assembly of components and subsystems, including the
necessary connectors, used for lifting and lowering a worker to and from a work station which is
not accessible by other preferred means, and potentially for positioning the worker while at that
work station. When working with the suspended personnel hoisting type of system, the user
should use a back-up a fall arrest system of either the self-retracting lanyard type or the fall
arrester (rope grab) type.

COPYRIGHT ©2015, SAYFA SYSTEMS 13 FDIM-01- REV D-DA300- NO INSPECTION 15/09/15
7.1.3. FALL ARREST SYSTEMS
A fall arrest system is an assembly of components and subsystems, including the necessary
connectors, used to arrest the user in a fall from working height and suspend the user until
rescue can be affected. A fall arrest system must always include a harness and connecting
means between the harness and an anchorage or anchorage connector. Such connecting means
may consist of a lanyard, energy (shock) absorber, fall arrester (rope grab), lifeline, self-
retracting lanyard or suitable combinations of these. The folding davit base mounting bracket
eyebolt attachment point is a suitable anchorage connector in a fall arrest system.
7.1.4. CLIMBING PROTECTION SYSTEMS
A climbing protection system is an assembly of components and subsystems, including the
necessary connectors, used to arrest the user in a fall from a working height and suspend the
user until rescue can be affected. Such systems are used for climbing ladders and structures that
are designed for climbing. They may either be temporary (portable) or permanent. Permanent
climbing protection systems are ones of the rigid rail type such as the SAYFA RAPTOR RAIL™
system. In those systems, a rigid rail is permanently attached to the structure to be climbed. A
fall arrester device is attached to and glides on the rail to permit ascent and descent.
7.1.5. RESTRAINT SYSTEMS
A restraint system is an assembly of components and subsystems, including the necessary
connectors, used to: (a) stabilize and partially support the user at an elevated work location and
allow free use of both hands. This type of restraint system is referred to as a work positioning
system or, simply, a positioning system. (b) Restrict the user’s motion so as to prevent reaching a
location where a fall hazard exists. This type of system is referred to as a travel restriction
system. A positioning system includes a harness and connecting means between the harness and
an anchorage or anchorage connector. Such connecting means usually consists of a positioning
lanyard which is connected to both hip D-rings and wraps around or connects to an anchorage or
anchorage connector. A positioning system must always be backed up by a fall arrest system. A
travel restriction system consists of a harness and a fixed-length or adjustable-length lanyard
connected between any one of the harness D-rings and an anchorage or anchorage connector.
7.1.6. EVACUATION SYSTEMS
An evacuation system is an assembly of components and subsystems, including the necessary
connectors, employed by the user to move, unassisted by others, from a hazardous place to a
safe place under alert or emergency conditions. An evacuation system consists of a harness and
connecting means between the harness and an anchorage or anchorage connector. The folding
davit is generally not used in evacuation systems.

8. COMPATIBILITY OF SYSTEM PARTS
8.1.1. COMPATIBILITY OF CONNECTORS
Connectors, such as D-rings, snap hooks, and karabiners, must be rated at 22 KN minimum
breaking strength. Connecting hardware must be compatible in size, shape, and strength. Non-
compatible connectors may accidentally disengage ("rollout").
8.1.2. ANCHORAGES AND ANCHORAGE CONNECTORS
An anchorage is generally a fixed structural member such as a beam, girder, column, floor, or
wall. The folding davit and mounting base is an anchorage connector for personnel riding
systems and for personal fall arrest systems. Anchorages and anchorage connectors for personal
fall arrest systems must have a strength capable of supporting a static load, applied in directions
permitted by the system, of at least 15 KN.
9. PLANNING THE USE OF SYSTEMS
Perform the hazard identification and evaluation described in section 2.0 of these instructions.
Then plan the system before starting work. Consider all possible paths of user movement and all
factors that could affect the user’s safety before, during, and after a fall anywhere along these
paths. A qualified person must select the components, materials, anchorage and anchorage
connectors to match the system application, the work, workplace hazards, and the environment.
Consider the following points when planning the system(s).
9.1.1. ANCHORAGE AND ANCHORAGE CONNECTOR SELECTION
Determine the necessary locations of anchorages to assure that the user will be continuously
connected when exposed to hazards of falling. Select anchorages that are stable and have the
strength required by section 5 of these instructions. Carefully select the locations of the
anchorages to: (a) reduce possible free fall distance, (b) prevent swing fall hazards, and (c)
provide clear space in the potential fall paths to avoid striking an object. Do not select
anchorage locations that will require the user to work above them as this will increase the
potential free fall and total fall Factor. Plan the types of anchorage connectors that will need to
be selected and refer to those instructions.
9.1.2. FREE FALL DISTANCE, TOTAL FALL DISTANCE, AND SYSTEM ELONGATION
Personal fall arrest systems must be selected and rigged to ensure that potential free fall
distances will never exceed a fall factor of 2, with a 2M lanyard this would be a total fall distance
of 5.75M if the energy absorber deploys to 1.75M. Please allow a safety distance of 1M for the
elongation of the system. This means that you need a clear distance of 7M or greater for the
system to be affective.

COPYRIGHT ©2015, SAYFA SYSTEMS 15 FDIM-01- REV D-DA300- NO INSPECTION 15/09/15
9.1.3. USER MOVEMENTS
Identify all necessary movements of the user and the materials and equipment needed to
perform the planned work. Plan for avoidance of the crossing or tangling of connecting
subsystems of two or more workers. Anticipate user movements that might introduce hazards
of the connecting subsystem passing under, about or between body parts or invite the user to
clamp, knot or otherwise prevent the connecting subsystem from functioning properly.
Establish controls to prevent these occurrences.
9.1.4.PENDULUM (SWING) FALLS
Swing falls can occur when the system is not anchored directly above the user. The force of
striking an object in a pendulum motion can cause serious injury. Always minimize swing falls by
working as directly below the anchorage point as possible.
9.1.5. CLEAR SPACE IN FALL PATH
Make certain that enough clearance is available in all potential fall paths to prevent striking an
object. The amount of clearance needed depends upon the type of connecting subsystem used,
and the location of the anchorage. Allow at least 1 m below the user and within a radius 1.8 m.
This allows for some horizontal motion during the fall even if there is no swing fall possible.
9.1.6. HAZARDS IDENTIFIED IN WORKPLACE ASSESSMENT
All hazards of the type set forth in section 2 of these instructions must be addressed and suitable
controls planned and implemented. For example, if work must be performed near unavoidable
sharp edges, plan to protect against cutting by use of heavy padding or other means of covering
the sharp edge.
9.1.7. RESCUE AND EVACUATION
The user must have a rescue plan and the means at hand to implement it. The plan must take
into account the equipment and special training necessary to affect prompt rescue under all
foreseeable conditions. Although a rescue plan and the means to implement it must always be
in place, it is a good idea to provide means for evacuation without assistance of others. This will
usually reduce the time to get to a safe place and reduce or prevent the risk to rescuers. The
folding davit and mounting base are suitable for use in rescue systems but not used in
evacuation systems.
9.1.8. PERSONNEL-RIDING SYSTEM ASSESSMENT
The user must take into account several factors when planning the use of a personnel-riding
system, these include but are not limited to the following; Make certain that enough clearance is
available around, above and below the folding davit and mounting base to allow the operator
and user to move about unimpeded in the entire range of movement of the folding davit and
mounting base and compatible components. The user that is suspended by the personnel-riding
system must have a fall arrest system providing personal fall arrest capability. The user that is
operating the personnel-riding system must have a restraint system to restrict the user's motion
so as to prevent reaching a location where a fall hazard exists. The user that is operating and the
user that is suspended by the personnel-riding system must have a means by which to
communicate while using the personnel-riding system.

10. Care , Maintenance and Storage
User maintenance consists of cleaning and drying the folding davit. All other maintenance or
repair/work must be done at the factory or by a person who has been authorized.
10.1.1. FOLDING DAVIT INSPECTION BEFORE EACH USE
Inspect the folding davit and mounting base to verify that it is in serviceable condition. See
section 12.1.4 for inspection details. Do not use folding davit or mounting base if inspection
reveals an unsafe condition.
10.1.2. DISASSEMBLING THE FOLDING DAVIT AFTER USE
To disassemble the components of the davit system, reverse the sequence for assembly. Do not
leave the Davit in place for prolonged periods in a corrosive environment. Inspect the system
after each use, Stow the equipment in a clean dry area when not in use.
10.1.3. CLEANING INSTRUCTIONS
To clean, periodically use a clean damp cloth to remove dirt or contamination which may cause
corrosion or hamper readability of labels. Wipe off any moisture before returning the device to
service. The frequency of cleaning should be determined by inspection and by severity of the
environment. In highly corrosive environments cleaning should be done every two or three days.
Never use solvents to clean folding davit and mounting base as they may break down the label
adhesive. Don't use abrasives to scour the davit or base as they may damage the plating and the
labels. To remove oil or grease, use a mild dishwater detergent on a damp cloth or sponge and
follow by repeated swabbing with a clean damp cloth to remove all soap residues. Never
immerse the product in water or other liquid.
10.1.4. STORAGE
Store the device in a clean, dry place indoors. Store the product away from heat and steam and
never allow it to rest for lengthy periods of time on concrete floors as the lime sulphur can cause
corrosion.

competent person who is qualified to perform a Formal Inspection as set forth in section 12.1.7.
12.1.3. MOUNTING BASE INSPECTION
Inspect for damaged welds by visually examining each weld area for signs of cracking. Visually
examine the entire assembly for deformed, altered, or damaged parts. Inspect labels to verify
that they are present and legible. Verify that no obstructions are present on the base tube which
could prevent the folding davit from fully seating on the base. Verify that the mounting base is
mounted flush against the anchorage and that all Nuts & bolts are present and tightened to
60Nm.
12.1.4. FOLDING DAVIT INSPECTION
Inspect for damaged welds by visually examining each weld area for signs of cracking or breaks.
Inspect the clevis pins for damage by visually examining the entire pin for signs of bending or
deformation. Verify that the nut on the travel restraint eyebolt is snug, but not binding the hinge
bracket to the lower tube. Inspect the upper and lower davit tube for damage by visually
examining the tubes for cracks, bending, or deformation. If inspection reveals any defect,
remove the device from service and label "Unusable" until it is repaired or destroyed. The
folding davit and mounting base are not field-repairable. Never attempt field repairs.
WARNING!
CAUTION! Inspection of all components is necessary by a competent person other than the user,
at intervals of no more than six months.
