Design

HADEF electric wire rope winches Type 45/10 E + 46/21 E + 95/18 E EX + 96/21 E EX have been developed
for stationary use.
Serial winch with ungrooved drum. Grooved drum as option.
Type 45/10 E + 95/18 E EX
with torsion-free base frame
4.2.1 Wire rope exit direction
For winches with ungrooved drum and winches without overload protection, the wire rope exit can be chosen
during assembly in nearly all directions.
The wire rope feed out direction is determined for winches with overload protection.
For winches with grooved drum, the winding direction of the wire rope is given by the grooves on the drum.
Winding direction "A" is supplied as standard.
In case of changes of the winding direction of the wire rope, electrical wiring must also be changed according
to the wiring diagram.
NOTICE!
For winches with grooved drum the direction of unwinding the wire rope cannot be changed afterwards.

Functions

The lifting gear are operated by pressing the push buttons on the control switch. The spring-pressure brake
installed in the electric motor of the lifting gear prevents the independent lowering of the load after the push
button has been released.
