Single-use, yet extremely useful protection: With its crash dampers, ACE offers engineers a single-use solution as a high-efficiency plant safety option. Each crash element, made of custom designed aluminium piping or steel, absorbs even high inertia forces almost instantaneously in the event of an impact. When arranged in series or parallel, the crash elements can absorb even higher energy values at once.

Other advantages of the emergency stop systems developed in sophisticated test series are their simple installation, ease of retrofitting in existing plants, speed of replacement and reduced downtime after a crash. The deformation of the crash box also allows the incident to be reconstructed, ideally helping avoid the same problem in future.

With these benefits, the crash dampers are already protecting many linear axes in robotics applications as well as the limit positions of tool machines, conveyor systems and high bay rack feeders.
