─ The electricity for the hoist motor is
controlled through a semiconductor relay
which is switched from a 48 V control
voltage.
─ The control voltage can be switched using a
pendant control or radio remote control.
─ The control consists of a supply PCB and a
semiconductor relay PCB attached above it.

─ The electricity for the hoist motor is
controlled through a semiconductor relay
which is switched from a 48 V control
voltage.
─ The control voltage can be switched using a
pendant control or radio remote control.
─ The control consists of a supply PCB and
two semiconductor relay PCBs attached
above it. One of them controls the hoist
motor, the other controls the trolley travel
motor.
─ In the GM2, the installation of this electronic
control is only possible through an
additional housing.
