The type of buffer used by the crane
 

if the normal operation of the location of the city limit device or brake device failure problems, because of the inertia of the problem, the operation of the end of the device will be a collision. The main goal of the device buffer in the crane is to absorb the energy during operation and reduce its impact. The main use of the buffer on the crane is the following types: Solid Buffer: Mainly can be divided into rubber buffers and polyurethane buffers. Rubber bumper structure is relatively simple, can absorb the energy is relatively small, usually used in the crane operating speed of not more than 50 meters per minute place, can play a blocking role. Polyurethane foam absorber excellent performance, excellent buffer performance, oil, aging resistance, acid resistance, corrosion resistance and excellent performance.
