Lock plate for Terex HC230

The lock plate 4056 082 00 serves as a mechanical security component within the Terex HC230 crane. Its primary function is to lock fasteners such as bolts, nuts, or pins in place, preventing them from rotating or loosening due to the dynamic loads, vibrations, and rotational forces inherent in crane operation. By maintaining the integrity of these connections, the plate helps preserve the alignment and stability of critical assemblies, including those associated with shafts, bearings, and structural joints.

This component is specifically engineered for fitment on the Terex HC230. It features a precise configuration of holes and tabs that align with the machine's hardware, allowing for a secure installation that resists displacement over time. Proper application of this locking mechanism is a standard procedure for maintaining the mechanical security of the crane's internal systems.

Lock plates function as a secondary retention system in heavy machinery. They are typically installed over a primary fastener and deformed or indexed to create a positive lock, ensuring that the fastener cannot back out under operational stress. This simple yet effective design is used throughout heavy equipment to protect against the loosening of components that are subject to constant movement or high torque.
