Infrastructure

EFDYN specializes in the shock and vibration isolation of complex structures like bridges, high rises, highways, and more. Our shocks and dampers have been used in civil engineering projects around the world, including bridge design and to aid in the earthquake resistance of buildings. While most of our products are stock, allowing for quick delivery, we also offer custom fabrication services through our sister company, Cimarron Machine.

Our Products

Our motion control products include:

Shock absorbers: Our industrial shock absorbers offer crucial energy absorption and linear deceleration for overhead bridge and trolley cranes and other infrastructure.
Custom shock absorbers: EFDYN also builds custom shock absorbers for bridges and buildings. Work closely with our sister company, Cimarron Machine, to design the motion and vibration control products you need.
Rotary dampers: We manufacture both limited and continuous rotation viscous dampers ideal for seismic damping, retrofit solutions, and more.
Crane bumpers: Our bumpers are made of durable elastomer that won’t easily scuff or tear even when exposed to harsh conditions.
