Working reasons of crawler crane idler: The working principle of crawler crane idler is as follows: use a grease gun to inject grease into the grease cylinder through the grease nozzle, so that the piston extends outward to push the tension spring, so that the guide wheel moves left to tighten the crawler track. The tension spring has an appropriate stroke. When the tension force is too large, the spring is compressed to play a buffering role; after the excessive tension force disappears, the compressed spring pushes the crawler crane idler to its original position, so that it can slide along the crawler frame to change the wheelbase, ensure the disassembly and assembly of the crawler track, reduce the impact of the walking process, and avoid the derailment of the track chain.
