Hydraulik Power Unit

Hydraulic brakes receive their impulses from hydraulic Hydraulic power units supplied by HANNING & KAHL reliably control all functions which are necessary for the operation of the braking unit. Our hydraulic power units have a compact design consisting of three parts: tank, manifold and hood. The basic device is particularly compact. Special functions can be fitted on request yet while convenient, they require more installation space. Hydraulic power units are ideal for deployment in low-floor vehicles where very little space is available. It is possible to activate all the brakes on the bogie by means of a common hydraulic circuit or to control the brakes of each axle individually using separate hydraulic circuits depending on the hydraulic units selected.
