Accessory 252100574 (drawing number Z5G.6.3) has been confirmed to be the boom cylinder frame pin of XCMG ZL50G loader, which is a critical connecting component of the working device

Accessory 252100574 (Z5G. 6.3) is a hinge pin shaft at the connection between the hydraulic cylinder of XCMG ZL50G loader arm and the frame. Its core usage scenario is the connection of the boom lifting fulcrum under heavy load conditions.
Structural connection: used to firmly hinge the cylinder body end (earring) of the boom hydraulic cylinder to the ear seat of the front frame of the loader, forming a fixed fulcrum for the hydraulic transmission of the working device.
Torque transmission during shoveling and lifting operations bears the enormous thrust generated by hydraulic cylinders and the composite load transmitted by the boom, ensuring effective conversion of power into bucket action.
Heavy load adaptation: specifically designed for the ZL50G series (rated load capacity of 5 tons), especially suitable for high-intensity, high impact working environments such as mines, quarries, ports, etc. It needs to be used in conjunction with a dedicated liner to resist wear and tear. ‌‌
