Safety shock absorber
max. 76 kN | CB63 - CB160 ACE Stoßdämpfer GmbH

ACE safety shock absorbers are selfcontained and maintenance-free. They
are designed for emergency deceleration and are an economic alternative to industrial shock absorbers. The primary oil seals are protected inside the main body and only a wiper seal is necessary on the piston rod. Dirt or contamination on the piston rod does not cause oil leakage or failure as is often the case with conventional buffers. The integrated gas chamber enables the CB series safety shock absorbers to provide return forces of up to 76 kN. This high return force is necessary for multiple-bridge cranes where the buffers must separate the bridges after an emergency collision. Normal buffers would remain compressed after such a collision and would not be capable of accepting further impacts. The robust, large-dimensioned piston rod bearing system, is designed for very heavy duty use and is equivalent to that used in other buffers 80% larger in size. The CB series units are custom-orificed to suit your specific application and provide a smooth constant deceleration through-out their complete stroke length.
