The YDGZ-40 hydraulic lever top rail brake is primarily utilized for the windproof braking of cranes and harbor and dock loading and unloading machinery of medium to large sizes in both active operations and at rest.

It can be used for safety braking in case of sudden gust of wind when the crane is operating.

Normally closed design, centralized drive control by hydraulic station, top rail brake is realized by special disc spring.

Friction block adopts advanced high wear-resistant steel, with reliable performance.

With manual release, it is easy to install and maintain.

Equipped with limit switch to indicate the operating status.
