ADLER electric winches with brake release device

The brake release device on an electric winch acts on the braking system. Using the release lever the brake can be opened slowly to lower loads without employing electrical energy. When releasing the brake the hand wheel must not be engaged as otherwise it would rotate at motor speed when lowering. Loads can be lifted by several centimetres using the hand wheel. For example, to lift a cage or release a cage from the limit stop.
A brake release device with hand wheel is mandatory for goods lifts. The hand wheel is not suitable for hoisting loads over a larger distance because only a short distance per revolution of the hand wheel is achieved, and the brake must be opened with one hand. In this case, we recommend the use of a standby manual drive.

The hand wheel must always be disengaged in the event of motor-driven operations and must not rotate with the motor. On the electric winches WE 5, WE 10 and WE 20, the electric drive is automatically locked when the hand wheel engages. These winches are not available with built-in reversing contactors as there is insufficient space within the housing for them to be fitted. Control must be effected from a separate switchbox (except WE 1. In this case the drive is not locked electrically and the reversing contactors can be fitted in the winch). 

A stroke limit facility can also be fitted in conjunction with the brake release device but only in a special housing. The shut-off distances of the standard stroke limit do not apply in this case. Detailed shut-off distances upon request.
