2. Important Notice
READ THE EQUIPMENT LABELS AND ‘USER INSTRUCTIONS’ BEFORE USING THIS PRODUCT.
BEFORE USING THIS EQUIPMENT IT IS ESSENTIAL THAT USERS ARE FULLY AWARE OF HOW THE EQUIPMENT
OPERATES, WHERE IT SHOULD BE USED, WITH A PREDETERMINED ACTION PLAN FOR BOTH THE USE AND
RECOVERY SHOULD AN EMERGENCY ARISE.
This product has been developed to enable the safe entry/exit of personnel into a confined space or to an
area of restricted access. It is recommended for use in conjunction with the G.Davit, G.Winch for hoisting
personnel and the G.Saver II fall arrest and retrieval device, to protect against falls occurring during use. The
G.Saver II also provides a backup retrieval system for use in an emergency or an unforeseen occurrence. Third
party devices are not recommended.
This equipment is for use where other means of carrying out the work or routes of access are not practical.
When in use, please observe the Maximum Working Load of the G.Davit and of all associated equipment
being used. The person on the rope end of the davit should never be left to work alone. There must always
be another person present to supervise and operate the G.Davit and the equipment used with it.
Both the person on the rope end of the davit and the equipment operator should be adequately trained and
competent.
This equipment shall not be used outside of its limitations, or for any purpose other than that for which it is
intended.
It is prohibited to make any alterations or additions to this equipment without the prior, written consent of
Globestock Ltd. Any necessary repair will be carried out by Globestock Ltd, or by an authorised Globestock Ltd
service agent, in line with our procedures.
PRIOR TO USE:
A formal ‘Risk Assessment’ should be carried out, considering use and the emergency rescue procedure.
An emergency contingency plan must be in place to rescue the worker in the event of an emergency, before
entering the confined space or area of restricted access to carry out work.
Users should be fully conversant with the operation of the equipment.

3. Adjustable Clamp Socket
The Adjustable Clamp Socket is one of a variety of davit base mounting options. It is a transportable
aluminium clamp-style socket that can be installed in a few minutes. The Adjustable Clamp Socket can be
fitted to a wide range of vertical structures, such as walls, pilings, trench boxes or any strong vertical
structure. It can be quickly installed and the davit arm inserted into the socket, prior to use. Once work has
been completed, the Adjustable Clamp Socket can be quickly and easily removed.
This Adjustable Clamp Socket provides a base mounting socket for a davit arm such as the G.Davit, from which
fall protection or personnel lifting operations may be carried out for access to below ground or areas of
restricted access. Fall arresters and personnel hoists are some of the equipment that can be fitted to the
G.Davit. With dual pulley sets, the G.Davit can accommodate two pieces of work equipment.
The wall, pilings or vertical supporting structure must be strong enough to support a bending moment of
8,400 Nm. If there is any doubt about the strength of the supporting structure then get it assessed by an
appropriately experienced engineer or seek the advice of the supplier/manufacturer. For example, the
supplier/manufacturer of any pilings used.
When work has finished, the G.Davit can be lifted out of the socket, the socket unclamped and both items
removed from site.
It can be used as a fall arrest anchorage device or for the regular raising/lowering of personnel. For example:
lifting personnel through areas of restricted access or for confined space entry.
The G.Davit model D200/60, with a reach of 0.6m, is recommended for use with the Adjustable Clamp Socket.
The Adjustable Clamp Socket has a maximum working load limit of 200kg for lifting people and 250kg for
lifting equipment when used with the G.Davit D200/60 with 60cm reach.

4. Considerations for use.
•Do not exceed the maximum working load of the Adjustable Clamp Socket.
•Should any doubt arise about the safe condition of this device DO NOT USE. Return to Globestock or a
Globestock-authorised service agent for assessment, service and re-certification, before further use.
•The G.Davit weighs approximately 17kg. Locating the G.Davit into the socket may require two people.
•This equipment must be used by at least two people; one to operate the equipment and the other on
the rope end.
•The equipment operator should maintain communication at all times with the person entering/exiting
the confined space or edge.
•The G.Davit and associated equipment may only be used by persons who are trained and competent in
its safe use.
•Personnel protective equipment should be worn when using this equipment. For example: gloves,
safety glasses, safety shoes, etc.
•Consideration should be given to operator restraint, edge barriers or other methods to reduce the risk
of falling.
•Before work commences, a clearly understood, predetermined action plan should be in place and then
implemented in the event of an emergency.
•Be aware of any medical condition that may affect the safety of the equipment-user in both normal
and emergency use. If there is any doubt seek medical advice or do not use the equipment.

5. Inspection Before Use
Before each occasion of use, the Adjustable Clamp Socket should be visually inspected and checked according
to the following instructions. This should be done by someone who is competent to do so.
Inspection
1. Before installation and assembly with the davit arm, visually inspect the general structure of the
Adjustable Clamp Socket. Pay particular attention to all welds. Ensure no cracks, damage, bent or distorted
material.
2. Visually inspect all over the Adjustable Clamp Socket’s structure.
3. Ensure that the adjustable leg locking pin is present and locates and tightens correctly. Ensure that the
clamp screws are present and functioning.
4. Visually check that the sleeves inside the socket are present and free of significant damage. Ensure that
they are free of grit and dirt that will score the G.Davit’s mast. Clean if necessary.
5. Ensure that the socket cap is present and retains the plastic socket liner.
6. Ensure that all fasteners are present and secure.
Before fitting the davit mast, the socket end can be cleaned if dirty, in order to help prevent grit and abrasive
particles becoming embedded into the socket sleeve, which can cause premature wear and damage to the
end of the davit mast. Before use, inspect the associated equipment, be clear on how it operates, and ensure
that the Adjustable Clamp Socket is fastened securely to the supporting structure.
Lifting of people: 200kg
Lifting of equipment: 250kg

6. Setup For Use
If in any doubt please contact either your retailer, Globestock or a specialist for advice.
Pre-use checks for all equipment must be completed. Where possible, the equipment should be inspected
and setup in a safe area. Once completed the equipment can then be moved to the area of work and
assembled ready for use. Two people may be needed to lift heavy or bulky items. Perform a final inspection
of the assembled equipment before use.
Locating the G.Davit into the Adjustable Clamp Socket (see fig. 2)
1. The G.Davit should be set down and inspected in a safe place, ideally away from the edge/confined
space or area of work.
2. Hold the G.Davit, standing on the side furthest from the edge. Lay the base of the davit on the top of
the socket.
3. The G.Davit weighs around 17 kg, so it may be necessary for two people to raise the G.Davit into place.
4. Raise the davit from horizontal to vertical, keeping the base end in the top of the socket. When the
main upright (mast) is vertical, lower the davit into the socket.
5. Setting up the equipment on the G.Davit should always be performed with the davit between the
operator and the edge/confined space entrance. The davit arm can be rotated to gain safe access to
the top pulley and upper arm (boom).
6. Setting up the equipment at an edge exposes the installer to the risk of a fall. Appropriate care and
measures should be implemented to ensure safety.

7. Socket Installation
The Adjustable Clamp Socket can be fitted over and attached to a wide range of vertical structures. Before
fitting, all of the clamp screws should be fully retracted so that they protrude equally.
The clamp socket should firstly be adjusted so that it will fit over the vertical structure. Unscrew and remove
the adjustment leg locking pin. Set the adjustable leg at a position that will snugly fit over the vertical
structure, then refit and tighten the locking pin.
Seat the clamp socket over the wall or vertical structure. Tighten up all of the clamp screws evenly so they
touch the wall and the clamp socket is equally spaced and level on the wall. Go around all the clamp screws
and tighten them up equally, ensuring the socket remains level on the wall. Go around all clamp screws a
further time to ensure all are tightened firmly. There should be no need to tighten the screws excessively.
The wall or vertical supporting structure must be strong enough to hold the clamp socket and G.Davit without
the possibility of failure. A single row brick wall (10cm wide) or trench piles produced from steel less than
6mm thick may not be strong enough. If necessary, seek the advice of an appropriately experienced engineer.
The wall or vertical supporting structure must be strong enough to support a bending moment of 8,400 Nm.
It is possible to provide additional support in some vertical structures, so that the load is spread over a greater
length of the structure. For example, a wall may have beams temporarily clamped to the front and rear of it,
so the load from the adjustable clamp socket is spread out along a much wider length of the wall. A similar
principle can be employed for uneven structures or pilings.

8. Inspection & Maintenance
The Adjustable Clamp Socket requires regular inspection and maintenance to ensure that it is safe to use.
Repairs should never be carried out on site or in the field. Do not tamper with or modify the unit.
a. Periodic Examination
Periodic Examination (this satisfies the requirements of LOLER and BS EN 365:2004).
The Adjustable Clamp Socket should be periodically examined by a competent person. An
examination should be carried out a minimum of once in every 6 months regardless of the
frequency of use and the operating environment. The ‘Examination Record’ found on the rear
cover of this booklet outlines the main examination criteria. On passing this detailed inspection
the examination record can be completed, signed off and the unit returned for use. If on
completion of an examination there are parts found to be in need of replacement or repair, the
unit should be returned to Globestock or a Globestock-approved servicing agent for a detailed
examination and service.
In the event of a fall being arrested (the fall arrester being used while attached to the G.Davit) the
G.Davit and brackets should be withdrawn from use immediately and returned to Globestock or a
Globestock-approved servicing agent for an examination/service.
b. Service, Test & Re-Certification
As outlined in 8a. the G.Davit and associated winch and arrester brackets and sockets require an
examination a minimum of once in every 6 months. In the event that a fault is found and the unit is
returned to Globestock or a Globestock-approved servicing agency, a full service and retest should
be carried out, a new test certificate will then be issued.
c. Cleaning, Storage & Transportation
The Adjustable Clamp Socket may be cleaned using warm water with a mild detergent.
The socket is best stored in a clean, dry, chemical-free environment.
When transporting the socket, it should be boxed or retained to prevent damage or deterioration.
