The overload protection serves exclusively to protect against damage to the device due to overloading
when moving loads. Its function must not be integrated into the operational work process!
Control
▫ Low voltage control (direct control depends on the kind of unit)
▫ Indirect control with phase sequence relay. The phases must be exchanged if the turning direction is
wrong.
▫ Units with limit switch are fitted with low voltage control.
▫ Radio control is available as option.
Control switch
▫ Control switch suitable for single hand use.
▫ The control switch housing is made of shock- and fracture-proof plastic.

Disengaging clutch (as option)
The disengaging clutch separates the drum from its drive. The clutch is actuated by a hand lever which is
locked by a spring-pin. Before operation, this spring-pin must be pulled by hand and hold until the hand lever
has moved some steps. It engages automatically after the switch operation has ended.
When the clutch is disengaged it is possible to pull the uncharged wire rope off the drum by hand. Should
there be an after-run of the drum, brake it with the foot brake.
CAUTION!
The foot brake must not be used to brake loads! This is not possible (if normal forces act). Unintended
switching is also prevented.
