The lock plate, part number 0669 923 27, is a component used in the Terex HC230 crane to maintain the integrity of critical bolted connections. It functions by preventing the rotation of nuts, bolts, or other fasteners that are exposed to constant movement, vibration, and heavy dynamic loads during crane operation. By providing a mechanical stop, the plate ensures that these fasteners remain tightened in their intended positions.
This component is compatible with the Terex HC230 model. It is designed to be installed in various assemblies where secure fastening is required to maintain structural and mechanical stability. The plate features tabs or specific geometries that interface with the fastener head or nut to lock it in place.
In heavy machinery, lock plates act as a secondary retention system for critical joints. They are commonly employed in structural assemblies, slewing mechanisms, and lift systems where the failure of a fastener could lead to significant mechanical issues. Regular inspection of these plates is standard practice during maintenance to ensure they remain in their correct position and have not been deformed by the forces exerted on the joint.
