Pontoon bridge ramp angle adjuster - consists of cylinder with piston thrust causing ramp to slope up or down

摘要

The pontoon bridge is designed to transport tanks and other military vehicles across a river and has a ramp (2) at each end. The bridge has a main girder (1) resting on two pontoons (4, 41). The angles of the ramps (2) relative to the main girder (1) are adjusted by hydraulic rams (12). When a tank is being loaded onto the tamp and transfers its weight to or pneumatic control system for the ram allows an elastic deflection, but the ram and main girder are not allowed to tilt to excessive angles.
