CONTROL
GEAR
A metal panel contains all the electric equipment for the starting, protection and control of the motors.
Auxiliary voltage is supplied via a transformer which is kept constantly connected. When required, auxiliary protection can be
provided by means of fuses and protections of suitable capacity on the main currents to the motors. Control equipment, inside its
case, requires periodic maintenance.
If a contactor does not close properly (single-phase current is supplied to the motors or the brakes) change the contact or change the
broken part completely.
If the crane has to work in a dusty environment, clean the remote control switches by blowing between them. In very humid conditions
(with the crane working outside) all electric components should be periodically sprayed with commercially available modern
water-repellent silicone-based product (make sure they are suitable for electric equipment).
Make sure fuses are inserted tightly; when replacing them see they are the same type.
Panel must not vibrate too much during crane operations so periodically check that the bolts are tight.
It is a good rule, at the end of each shift, to open the line main remote control switch by pressing the "stop" button.
For detailed information of the power and control circuits refer to the provided circuit drawings.

CONTROL
PENDANT
Control pendants are essential to the crane or hoist function, and can be subject to abuse.
It is necessary, therefore, to keep it constantly under check thus avoiding loss of work-hours, and operator safety. We
particularly suggest;
• Make sure it does not come into contact with oily substances, dampness or dirt; avoid bangs and squashing; do not
pull or twist the supporting cable; if needed move the panel gently; do not use the cable to pull the hoist; do not
allow knots or eyelets to form in the cable.
• Replace the hanging cable if any conductor has been damaged.
• Always keep a spare panel and corresponding cable in stock
