ACCESSORY TROLLEY ROLLERS
Grease regularly, on average every week.
Replace the roller when the slack exceeds 1 to 2 mm.
If the lift is in a state of disrepair that could cause risks to the user or the environment, it
must be taken out of service or dismantled.
Haemmerlin shall only guarantee the material if it is completely intact. If the equipment is
weakened by any kind of damage (shock, deformation, cut, tear, weld breakage, etc.), it must be
taken out of service or dismantled.
Haemmerlin is not liable for any consequences arising from failure to comply with the
aforementioned regulations.
REPAIRING MAXIAL ELECTRIC WINCHES
It is forbidden to carry out maintenance work on the electrical components without the power
supply having been disconnected and the capacitor having been discharged.
If one or more of the protections must be removed to carry out control or maintenance work, the
power supply must be disconnected and the capacitor discharged beforehand. These operations
must be carried out by qualified personnel.
If it is necessary to apply electrical power to the unit to perform certain checks, these checks
should only be performed under the supervision of a highly qualified supervisor.
THE WINCH DOES NOT WORK
* Check if it is connected:
- Power supply
- Remote control
- The upper limit switch and slack cable safety device
* Check that the emergency stop button on the remote control is unlocked.
* Check the general power supply 220V50Hz - 16/20A, by measuring the supply voltage on
the power extension cord (winch not connected) using a voltmeter.
If the power supply is not 220V, use another power source.
* Check if the thermal relay has tripped due to overheating of the motor. Wait for the
thermal relay to reset automatically after the motor has cooled down, then try the winch
going up and down. The thermal relay only acts on the ascent so that it can immediately
lower the load safely to the ground.
THE WINCH WORKS WHEN IN DESCENT BUT NOT WHEN IN ASCENT
* Check that the electrical contact on the upper limit switch fixed on the ladder is connected in order to
ensure that the electrical circuit is closed and the mechanical roller is released.
* Check that the wires of the plug and socket at the winch output are properly connected.
* Check that the wires of the electrical cable are correctly connected to the contacts of the upper limit
switch attached to the ladder.
* Check that the mechanical roller of the upper limit switch on the ladder is not damaged or defective.
THE WINCH WORKS WHEN IN ASCENT BUT NOT WHEN IN DESCENT
* Check that the electrical contact of the cable slack safety device is connected and that the push-button
has been released.
* Check that the mechanical push-button of the slack rope safety device is not damaged or defective.
* Verify that the moving equipment is not in the lower stop position, as the cable slack safety device would
instantly cut off the descent.
* Verify the lifting cable is properly wound around the winch drum. When the
lifting cable is taut, the roller is moved so as to release the cable slack safety device, which must not
be cut-off.
* Verify that the ladder is inclined enough (minimum 30° from the horizontal) to allow
