Cotter 3/16 for Terex BT4792

The 3/16 inch cotter pin, part number 215388, is a fastener used within the load ball assembly of the Terex BT4792 crane. This component is specifically utilized to secure pins, bolts, or nuts, preventing them from loosening or disengaging during crane operations. By locking these connection points in place, the cotter pin maintains the integrity of the load ball assembly, which is essential for the secure attachment of the hook and other lifting hardware during hoisting tasks.

This part is compatible with the Terex BT4792 model. It is designed to meet the specific size requirement of 3/16 of an inch for the designated assembly. Proper installation ensures that the connection points remain fixed, supporting the overall mechanical stability of the crane's lifting equipment.

In general engineering, a cotter pin is a metal fastener with two tines that are bent during installation. These pins are widely used in heavy machinery to lock mechanical assemblies, such as clevis pins or castle nuts, onto shafts or rods. Their primary function is to act as a secondary locking mechanism that prevents components from vibrating loose or detaching under dynamic loads.
