High resetting forces with gas pressure accumulator

Crane Installations, Optimized Characteristic
Energy capacity 80,000 Nm/cycle
Stroke 500 mm

Robust power house: The emergency stop for use in heavy duty areas from the CB63 to CB160 product family has internal system seals. 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 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.

Just like all ACE safety shock absorbers, the characteristic curve or damping characteristics of each individual CB representative is individually adjusted to the respective application.
