7.4 ELECTRICAL SYSTEM

Check the condition of the insulating pendant control case. If it
is damaged replace it with an original IMER spare. Make sure
that the steel cable connecting the pendant control to the
electrical panel is shorter than the electrical cable to protect
against pulling.
8. DISMANTLING THE HOIST
Remove all loads from the hook.
Wind the wire rope completely onto the drum. Disconnect the
power plug.
Remove the split pin from the support hinge and remove the
rotating frame.
If a trestle is being used, the carriage must be removed from
the hoist after it has been taken off the guides and before the
counterweight is removed.
9. TRANSPORT AND STORAGE
- Do not leave the installed hoist unattended without first
disconnecting the electric power supply and winding the rope
completely onto the drum.
When the machine is to be stored for a long period of time,
make sure that it is protected against atmospheric agents.
- During transport protect the machine from shock and crushing
which can adversely affect its functionality and mechanical
strength.
10. SCRAPPING THE HOIST
To scrap the machine at the end of its service life, carry out the
following steps:
a) Drain out the oil by removing the oil plug.
b) Separate the various plastic and electrical components
(cables, pendant control, etc.).
c) Divide up the metal components according to the type of
metal (steel, aluminium, etc.).
After the various components have been separated, dispose
of them through authorised disposal centres.
- Dispose of properly. These components can cause
accidents and pollution.

12. PROCEDURE IN EVENT OF FAULT WITH LOAD
SUSPENDED
- If possible remove the load from the nearest level, then
dismantle and service the hoist.
- If this is not possible, use another lifting machine (with adequate
lifting capacity) from higher up and suspend the faulty hoist
both at the load and at the hoist attachment point.
Lift the faulty hoist slowly off its fitting, then lower the entire
assembly to the ground.
- Do not attempt to turn the brake adjustment nut, as it would
become uncontrollable.
- Do not attempt to repair the fault on the machine with the load
suspended.
13. NOISE LEVEL AT THE OPERATOR S EAR
The level Lp(A) given in the TECHNICAL DATA chart
corresponds to the weighted equivalent sound pressure level
on scale A of European Directive 98/37. This level is measured
with no load, at the operator s head in the working position 1.5
metres away from the instrument, considering the different
working conditions.
