Functional characteristics speculate, the core function of the tensioner, the track tensioning system: adjust the tightness of the track by hydraulic or mechanical means to ensure that the track fits with the drive wheel and the support wheel, reducing wear and improving walking stability. Suitable models: XGC55 basic model and XGC55T crawler crane (need to verify the engine model and chassis configuration). Structure: Hydraulic oil cylinder drives the tensioning beam, cooperates with the guide pulley group, and injects grease through the oil injection nozzle to realize the tensioning force adjustment
