Safety Shock Absorbers
SDP120-100EU

High return forces with gas pressure accumulator

Crane Installations, Optimized Characteristic
Energy capacity 64,000 Nm/cycle
Stroke 100 mm

Reliabity: The emergency stop from the large scale SDP63 to SDP160 product family have internal system seals. Even dirt or damages to the piston rod do not lead to a leakage or failure. Compressed gas accumulators allow return forces of up to 100 kN, 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 absorber is individually adjusted to the respective application.

Application Examples

Safety Shock Absorbers - SDP63 to SDP160

Impact absorption for lock gates

Driving into lock gates should be specifically facilitated when navigating through Dutch river locks. That is why ACE developed special dampers, based on existing SDP safety shock absorbers but with optimized characteristics, a fixed stop and a st...

Application Areas

shelf storage systems
heavy load applications
Outer body: painted steel; Rod end button: steel; Piston tube: hard chrome plated steel

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.
