New crash dampers made to measure

In addition to the Tubus structural dampers, ACE will be presenting crash dampers as a one-way solution at Motek.

With the new crash dampers made of aluminum or steel tubes, ACE is also offering disposable solutions made of these materials for the first time. They are particularly suitable for preventing damage when using linear units in robotics and for protecting the end positions of machine tools, conveyor systems and high-bay storage and retrieval machines. In the event of an impact, they fold up in a predefined manner, similar to a crumple zone, and convert the resulting kinetic energy into heat, which is released to the outside. In the event of an accident, they protect structures by absorbing 98 percent of the energy evenly.

Quick replacement after a crash

Thanks to their material and design, ACE crash absorbers combine long-term stability in everyday use with safety in an emergency. They are easy to fit and can be replaced quickly after a crash. The new safety products are available with external diameters of 87.5 millimetres in the aluminum versions and 63 and 38 millimetres in the steel versions. Ten basic types are available as standard, with energy absorption ranging from 670 to 11,200 Newton meters per stroke in emergency stop applications. Depending on the type, the maximum stroke of the components is between 45 and 160 millimetres, whereby the low support forces of 13,000 to 70,000 newtons make a decisive contribution to securing structures. These values can even be increased on request. Like the structural dampers in the Tubus series from the automotive sector, they also provide cost-effective protection for structures against downtime.
