Selecting the Correct Grip/pull Machine
Grip/pull machines are available in a
range of capacities, with manual operation (hydraulic operation is
available for certain applications) for both lifting and pulling
duties. Various rope lengths are available.
Select the machine to be
used taking the following into account:
Type of machine - manual,
hydraulic - lifting or pulling capacity - length of rope and need for
Rigging arrangement - diverters, pulley
blocks - anchorage and suspension points - imposed loads.

They should be dry,
clean and protected from corrosion.
Rope should be carefully coiled
onto a suitable drum or frame for storage, taking care to avoid any

Using Grip/pull Machines Safely
Do not use defective grip/pull machines,
ropes, pulleys etc.
Check the rigging arrangement, that anchorage and
suspension points are secure and adequate for the imposed loads.
Ensure the correct rope is fitted and that it is not twisted or
kinked. The machine must be free to align with the rope.
operations do not exceed the marked SWL. The line pull must not
exceed that stated for pulling applications.
Only use the operating
lever provided with the machine and do not extend this with tubes
etc. Undue force will damage the machine or cause safety pins to
Do not attempt to operate the raising and lowering levers at
the same time.
For man-riding applications only use a machine
which has been designed or specially adapted for that purpose,
following the suppliers specific instructions. Additional safety
equipment will be necessary.
In-service Inspection and Maintenance
Follow the specific instructions for
maintenance issued by the supplier. These should be incorporated into
the site maintenance programme observing any particular needs due to
the site or working conditions. Lack of lubrication will result in a
jerky movement or failure to operate. Keep the machine well
lubricated. It is impossible to over lubricate grip/pull machines.
Regularly inspect the grip/pull machine and rope and, in the event of
the following defects, refer the machine to a Competent Person for
thorough examination: casing damaged or distorted; shear pins
distorted or broken; operating lever bent or distorted; incorrect
diameter sheaves used in association with rope; incorrect rope
fitted; rope is kinked, worn, corroded or has broken wires; wire rope
termination is damaged, cracked or pulled; terminal fittings damaged,
distorted, cracked or gouged; marking illegible; jerky operation; any
other visual defects or operational faults.
