Hydraulic locking unit (HLU)


Attractions in adventure parks and events are popular with young and old. Especially the latest developments often go to the physical limits for man and material. Passenger safety must be guaranteed at all times and in all situations - without compromise. For decades leading manufacturers of amusement rides have relied on HAWE Micro Fluid's hydraulic locking units and have thus gained the trust of numerous operators of amusement parks and rides. 

The heart of the system is the hydraulic locking unit (HLU) developed by HAWE especially for amusement rides and flying constructions. The unit is available in the sizes LE25, LE32 and LE-X.

You can learn more about the detailed functionality and sizes of our hydraulic locking units HLU also on our application page or in our brochure.
