The HKA hydraulic compact actuator sets standards for longevity with its reliability and wear resistance. User-defined installation and operating position and extremely simple installation provide flexible operation, even under unfavorable placement conditions.

Power unit HKA-A

Due to its complexity and compact design the HKA is specifically ideally suited to deployment in hydraulic systems. All necessary components are contained in the HKA such as drive motor, hydraulic pump, valve manifold, storage tank, emergency actuation and switch housing to create the hydraulic pressure required to open and close the hydraulic brakes. This means that it is possible to assemble the HKA directly to a brake system (brake console). Losses of current in the hydraulic pipes can be minimised by the short distance to the brake system. Other points in favour of the HKA are a reduction in installation costs, the possibility of incorporation into the system diagnosis through sensors as well as the modification diversity of the hydraulic valves that can be installed.

HKA-L External Working Cylinder

The actuator type HKA-L is based as well on an electrohydraulic basic unit working in conjunction with an external hydraulic cylinder. The generated working pressure is transformed into a linear movement. Actuating forces and stroke length are dependent on the cylinder size. According to local requirements, the actuator may be fixed by means of flange, foot or shaft joint.
