If the cart of a single crane accidentally rushes to the end of the track travel, the hydraulic buffer can work together at the end of the track at the same horizontal height (another safety device); if two cranes on the same span track In the event of a collision, the oil pressure buffers located on the opposite sides of the metal structures of the two cranes have an effect. After the hydraulic buffer deforms itself, it immediately converts the kinetic energy of the collision into the absorption of elastic potential energy, which further reduces the impact of the collision force, which prevents the crane from damaging. Common rubber buffers, spring buffers and hydraulic buffers and so on.
When the limiter of the working machine area and the braking equipment fail, due to the inertia, the crane or trolley working to the end point will collide with the stopper of the device at the end point of operation. The function of setting up the oil pressure buffer is to absorb the operation function of the crane or crane to prevent impact. The hydraulic shock absorber is arranged at the place where the crane and the crane trolley collide with the stopper. Buffers are also required between cranes working on the same track and between double trolleys on the same bridge.
