4.7 MAINTENANCE

The maintenance schedule includes ordinary
procedures such as inspection checks and
tests directly performed by the operator and/or
qualified staff, responsible for normal company
maintenance and periodic procedures,
including adjustments and lubrication,
performed by staff trained by the manufacturer
by means of specific courses or publications.

4.7.1 ORDINARY MAINTENANCE

Ordinary maintenance covers procedures that
may be carried out directly by the operator or
by specialised technicians according to the
prescriptions of this manual and which do not
require the use of special instruments or tools.
The procedures consist of:
Daily steps performed by the operator and
including:
• general visual checks;
• functional tests (of motors, limit switches,

brakes without load, "START/STOP" push
button");

• condition check of ropes and hooks.
Weekly steps performed by specialised
technicians, including.
• visual check of each mechanism and of

lubricant leaks;

• functional check of the brakes with load;
• check of the limit switches and, if necessary,

lubrication of the mechanisms, levers or
control cams of the limit switches, to ensure
the proper fun and limit the wear;

• check of function and integrity of the keypad

and of the relevant cable.

Monthly steps performed by specialised
technicians, including:
• check of ropes and rope guide for efficiency;
• check of pulley for wear;
• check of wheels for wear;
• check and cleaning of plug and socket

connectors;

• check of oxidised contacts: after cleaning.

cover them with a thin layer of Vaseline;

• lubrication check of the cable trailers and the

cables;

• check the efficiency and integrity of the

power supply line and of its components;

• visual checks of the equipment inside the

control boxes, to ascertain the presence of
dust, if any.

The recommended steps are indicative; they
may be increased or decreased according to
the operation time of the hoist.

Manoeuvres - It is good practice to carry
out one movement at a time, since only this
way a manoeuvre can be started, stopped
and constantly followed by the operator,
who must avoid repeated switching on/off
in case of short movements. in fact, it is not
true that manoeuvres activated with "short
bursts of current" are advantageous. Only a
precise definition of the manoeuvre's starting
and ending time allow real saving of time and
energy.

Lighting - The hoist and trolley are not
equipped with their own standard lighting
system. the ambient lighting must allow the full
safety operation of the hoist for the intended
purpose. When carrying out maintenance
steps in badly lit areas and/or parts of the hoist,
a portable lighting system must be prepared,
taking care to avoid patches of shadow which
may obstruct or reduce the visibility at the
point where the work is being carried out or in
the surrounding areas.

4.6 SWITCHING OFF AT END OF WORK

To switch off the hoist at end of work, observe the
following:

remove the load handling slings from the lifting
hook

for a hoist with trolley, move the machine to the
area chosen for its storage when still.

Lift the hook in order to avoid dangerous
interference with persons and objects under
the machine.

Stop all movements of the hoist pressing the
"STOP" button.

Position the keypad where it cannot be
"disturbed".

Disconnect the power supply to the hoist
turning the main switch to "OFF" or "0";
