  • Crane buffer working principle

         Abstract: In the crane buffer through its own deformation, quickly absorbed the collision kinetic energy into elastic potential energy. Thereby reduce the impact of the collision force effect. Common has rubber buffer, spring buffer and hydraulic buffer. If a single crane carts ( or car ) accidentally rush at orbit stroke end, Buffers can and at the same level of rail end stop (another type of safety device) interaction; If in the same span two cranes have collided in orbit, and two cranes with metal structure located at the opposite sides of the buffers plays a role. Buffers throu...

  • The Principle of hydraulic damper

        Hydraulic damper is a device that to reduce the resistance of movements, and then depletes the kinetic energy. Hydraulic damper is widely used in automotive and medical equipment; the feature is the resistance changes with running speed. Obviously, it can play a buffer role in connected institutions. The most important feature is that the force of the gas spring changes with velocity of movement. Significantly, when the force point of gas spring movement faster, then the resistances of the spring is increased. In other case, when the force point movements is slow, almost no resistances.
