ACE Stoßdämpfer GmbH

High resetting forces with gas pressure accumulator

Crane Installations, Optimized Characteristic
Energy capacity 141,600 in-lbs/Cycle to 4,248,000 in-lbs/Cycle
Stroke 3.94 in to 31.50 in

Robust powerhouse: the CB63 to CB160 product family with internal system seals are used in heavy duty areas for emergency stop. Even dirt or scratches to the piston rod do not lead to a leakage or failure. Compressed gas accumulators allow return forces of up to 22,481 lb. (100 kN) in the CB models, which can make applications in multiple bridge crane systems safer, for example. The absorber body and the robust, large-sized piston rod bearing are also designed for heavy duty operations.

ACE uses our proprietary custom calculation program to design each shock absorber for the specific customer application. Customization helps reduce the risk of crashes and incorrect product sizing. Just like all ACE safety shock absorbers, the characteristic curve or damping characteristics of each individual CB unit is individually designed to the customer application.

Whether its crane systems or machines in heavy duty applications e.g. in the metal industry or in mining, these powerful safety shock absorbers reliably protect construction designs against expensive failure.
