SAFETY PRECAUTIONS
Always read instructions before setting up the equipment and before use.
Failure to heed these warnings may result in damage to equipment or serious
personal injury.
WORKPLACE SAFETY
1. ALWAYS inspect the gantry before use to ensure it is correctly assembled
and in good condition and replace any damaged or worn parts.
2. Only use the gantry on a flat, solid, level surface preferably concrete which
is capable of bearing the weight when loaded. Never work on soft/
unmade ground as the castors may sink in causing the gantry to topple.
3. Ensure the gantry operator is trained in both operation and safety aspects.
4. DO NOT allow personnel to use the gantry unless they have read these
safety precautions.
5. Use the gantry in a suitable, well lit work area. which is tidy and free from
unrelated items.
6. DO NOT use the gantry when you are tired or under the influence of
alcohol, drugs or intoxicating medication.
7. Keep all bystanders at a safe distance whilst the gantry is in use.
8. DO NOT over-reach. Keep your proper footing and balance at all times.
9. Safety equipment such as gloves and non-skid safety shoes will reduce the
possibility of personal injuries.
INSPECTION BEFORE USE
1. ALWAYS visually inspect the gantry before use, to ensure that all parts are
correctly located and secure. Check for cracks, deformation or other signs
of damage or worn parts and check the castors for damage. Do not use
the gantry unless it is totally sound.
2. Check castors to ensure they move freely without undue wear to their
pivots and that the wheels are not cracked or damaged.
SAFE OPERATING PRACTICE
1. Only use chains, slings, hooks etc. with a rated capacity equal to, or
greater than that of the load and the gantry. Check that they are secure
and will not slip under load.
2. NEVER exceed the safe working load capacities specified.

3. Lower the load as much as possible before moving the gantry. Do not use
the gantry to transport loads over long distances.
4. DO NOT allow the load to swing or drop suddenly whilst moving or
lowering.
5. DO NOT use this gantry to lift people or animals.
6. DO NOT work under any raised load.
7. NEVER climb on, or attempt to ride on the gantry.
8. Take care not to trap your fingers in the adjustable parts of the gantry.
9. Due to the weight of the loaded gantry, the help of an assistant will be
beneficial when moving the gantry around.
10. This is a heavy item (128kg). Take care when positioning or adjusting.
11. NEVER attempt to move a loaded gantry across a floor having cracks,
pebbles, or other obstacles which might impede its movement.
12. DO NOT move the gantry while heavily loaded in case it becomes
unstable. Do not use the loaded gantry on sloping ground.
13. ALWAYS ensure the crossbeam is level at all times.
14. DO NOT leave the load suspended when the gantry is unattended.
15. ALWAYS ensure the load is centred beneath the beam before lifting.
16. ALWAYS apply the brakes on each of the castors when the gantry is not
being moved around.
17. DO NOT push or pull the gantry crane with a fork truck or any other vehicle.
CARE OF THE GANTRY
1. Ensure that the gantry is properly maintained at all times and that no
corrosion is allowed to weaken any components.
2. If replacing parts only use those supplied by CLARKE International.
3. If the gantry has been subjected to an abnormal load or shock it should be
removed from service immediately and inspected by a qualified person.
4. NEVER tamper with the gantry or modify it in any way as this could prove to
be dangerous and will invalidate the guarantee. Only use the gantry for
the purpose for which it is intended.
5. The components of this gantry are designed to withstand the rated
capacity. Do not substitute any other components or exceed the rated
capacity of the gantry.
6. If the load capacity decal becomes worn or illegible contact CLARKE Parts
and service department on 0208 988 7400 for a replacement.
