The lockwasher, part number 901-00109, functions as a securing component within the rotation gearbox assembly of the Terex BT4792 crane. It is installed beneath the head of a bolt or nut to maintain fastener tension and prevent loosening caused by operational movement or dynamic loads during crane use.
This component is specifically utilized in the rotation gearbox, which manages the slewing movements of the crane superstructure. By ensuring that fasteners remain tight, the lockwasher helps maintain the alignment of the internal gears and the overall stability of the rotation assembly. This part is compatible with the Terex BT4792 model.
Lockwashers are standard mechanical components used in heavy machinery to prevent the rotation of threaded fasteners. They function by exerting spring force or creating friction against the mating surface, which resists the loosening effect of vibration and thermal expansion in mechanical systems.
