Lock washer for Terex RT-230 1XL

The lock washer, part number 220625, serves as a mechanical fastener component within Terex heavy machinery. Its primary function is to maintain the tension of bolted joints by resisting rotation caused by vibration, thermal expansion, and mechanical load cycles. By providing a locking force when compressed under a bolt head or nut, it ensures that threaded connections remain secure during the operation of the crane.

This component is compatible with the Terex RT-230 1XL rough-terrain crane and the T-560-1 truck-mounted telescopic crane. It is utilized across various assemblies, including engine mounts, transmission housings, and structural connections within the chassis and boom systems where joint stability is required. Proper installation of this washer is necessary to maintain the integrity of the machine's fastening points.

Lock washers are standard hardware used in heavy equipment to prevent the loosening of fasteners in high-vibration environments. They function by creating tension in the assembly, which increases the friction on the bolt threads and prevents the nut from backing off. Regular inspection of these washers is recommended during maintenance intervals to ensure they retain their spring tension and structural effectiveness.
