Lock washer for Terex BT4792

The lock washer, identified by part number 226846, is a specialized fastening component utilized in the topping cylinder assembly of the Terex BT4792 crane. Its primary function within this hydraulic cylinder system is to provide resistance against the loosening of nuts and bolts that can occur during the operation of heavy machinery. By creating additional friction or tension against the mating surfaces, this component ensures that critical connections remain secure despite the operational stresses placed on the topping cylinder, which is responsible for adjusting the angle of the crane boom.

This component is specifically engineered for fitment on the Terex BT4792 model. It is integrated into the mechanical assembly of the topping cylinder to support the stability of the bolted joints. Proper installation of this washer is necessary to maintain the structural and functional alignment of the cylinder assembly during lifting operations.

Lock washers are used in various mechanical systems to prevent fastener rotation caused by vibration or thermal expansion. They act as a locking mechanism to maintain the required preload on bolted joints, ensuring that components remain tightly fastened throughout the service life of the machine.
