Low return force with spring assembly

Crane Installations, Optimized Characteristic
Energy capacity 708,000 in-lbs/cycle
Stroke 7.87 inch

Reduced return forces: the ACE safety shock absorbers from the EB-Family offer internal system seals, large sized piston rod bearings and the maximum energy absorption for emergency stop applications. However, an integrated spring package in the robust shock absorber body makes sure that the return forces are reduced to a fraction of those in the CB-Family.

The damping characteristics of the maintenance-free and ready-to-install EB models is individually designed specific to the customer application, just like all ACE safety shock absorbers.
