Piston pull - pressure limiter


Product introduction:

Piston pull - pressure limiter adopts the structure of sleeve built-in piston. Place resilient rubber cushion on two sides of the piston head in the sleeve to bear the pull force and pressure caused by longitudinal displacement of the beam body. It is applicable to the beam body of longitudinal series connection. It has simple structure and easy to install and widely used.

Articulated vertical displacement limiting device can be as falling-off prevention structure of simple beam and continuous beam of small and medium-sized span. The both sides are anchored in the side of beam and pier and to meet the rotating and displacement of bridge. When the displacement of bridge reaches design displacement, the device has enough power to avoid further displacement. When the displacement disappears and the bridge return to original state, the rubber washer will take buffer action and reduce the damage of beam and pier.


Project cases:

Bawanhe bridge of Darui railway, Xishansi bridge
