Device for opening and closing the cover of a sliding hatch of an armoured vehicle, in particular a tank.

摘要

The device has an automatic braking and locking device activated between a drive pinion (14) and an operating device. A brake hub (6) is arranged on an output shaft of the locking device, and exhibits a curve guidance. An adjustment sleeve (2) exhibits a curve guidance, which acts together with the guidance of the brake hub, such that a relative rotating motion causes a lifting of the hub against the force of a spring (7).
