Low return force with spring assembly

Crane Installations, Optimized Characteristic
Energy capacity 16,000 Nm/Cycle to 80,000 Nm/Cycle
Stroke 100 mm to 500 mm

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 much to a fraction of those in the CB-Family.

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

These safety shock absorbers reliably perform their services in crane systems and in numerous heavy duty applications, even if the power fails, because these hydraulic machine elements are autonomous braking systems.

Technical data

Energy capacity 16,000 Nm/Cycle to 80,000 Nm/Cycle

Stroke 100 mm to 500 mm

Impact velocity range 0.5 m/s to 4.6 m/s. Other speeds on request.

Reacting Force at max. capacity rating = 187 kN max.

Operating temperature range -20 °C to +66 °C. Other temperatures on request.

Mounting in any position

Positive stop Integrated

Damping medium Automatic Transmission Fluid (ATF)

Filling pressure approx. 0.55 bar to 1.1 bar. Rod return by integrated nitogen accumulator combined with additional return spring.


The shock absorber can be pushed through its stroke. In creep speed conditions the shock absorber provides minimal resistance and there is no braking effect.

On request

Special oils, special flanges, additional corrosion protection etc.
