the mobile equipment to descend by gravity. If the incline is not steep enough, a slack is created in the
lifting cable during the descent of the mobile equipment. This slack in the cable will be detected by the
parachute system that will mechanically block the trolley on the ladder and/or by the cable slack safety
device that will electrically cut the descent. To avoid this, the slope of
the ladder must be increas
ed, or use the “shallow slope trolley return system" code 312796501 or remove
weight from
the moving equipment to increase the gravity of the crew during descent.
* If the moving equipment is lowered in a jerky manner due to a slack rope system malfunction, action must
be taken on the adjustment cam to slightly reduce the spring tension.
THE WINCH STARTS BUT STRUGGLES TO LIFT THE LOAD
* Check the 220V50Hz power supply by measuring the supply voltage (using a voltmeter). If the
voltage is between 200 and 220V, the power supply is correct. If the voltage is below 200V,
a different power source must be used or an extension cord with a larger cross-section must be used
(conductor section 2.5mm2 for a length of 0 to 15m and 4mm2 for a length of
15 to 30m maximum).
* Check the motor brake by listening to see if it opens by pressing the up or down buttons on the
remote control. If the brake does not open or is not properly adjusted, in which case
the air gap needs to be adjusted to 0.3mm, or the brake coil is defective in which case the entire brake
must be replaced.
In both cases, the winch assembly must be dismantled in order to access the brake.
THE CIRCUIT BREAKER JUMPS UP AND DOWN
* Ensure that the power supply line can support a current of 20A, (starting current of the
winches =20A). Also ensure that it is initially protected by a high sensitivity differential device
30mA for the protection of persons and a circuit breaker at maximum 20A to protect the winches
against overloads or short circuits.
* Check the wiring and contact connections at the plugs, sockets and cable outlets.
* Check the electric motor by opening the motor terminal block to ensure that the wire connections
are correct and that there are no disconnected wires that could short-circuit.
THE UPPER LIMIT SWITCH DOES NOT WORK
* Ensure that the upper limit switch is correctly positioned on the ladder where you wish
to stop the upwards movement. The upper limit switch roller must be able to detect the arrival of the
trolley.
* Ensure that the electrical contact inside the upper limit switch box is not defective, in
which case it should be replaced.
THE SLACK CABLE SAFETY DEVICE DOES NOT WORK
* Ensure that the contact inside the lower slack cable safety box is not
defective, in which case it should be replaced.
* Ensure that the slack cable system is correctly adjusted. Otherwise, change the
adjustment cams to slightly increase the spring tension and optimise the position of the
switching cam in front of the push-button of the electrical contact of the low cable slack safety device. In
the case of slack in the lifting rope, the cut-off cam must act on the push-button of the electrical contact of
the lower cable slack safety device and could cause the descent to stop. Conversely, when the lifting cable
is taut, this cut-off cam must be completely free of the electrical contact of the lower cable slack safety
device
CHECK THE REMOTE CONTROL (low voltage 24V)
* Ensure that the emergency stop button is unlocked then try the winch.
* Ensure that all electrical wires are properly connected to the mobile plug and socket
or the socket outlet and that the cable does not have any cuts or tears.
* The winch does not work when the emergency stop button is unlocked:
- Open the switch box and make sure that all wires are properly connected.
* The winch does not work when the up button is pressed:
- Open the switch box and make sure that all wires are properly connected.
