Spring pin for Terex HC230

The spring pin, part number 0494 651 45, is a hollow cylindrical fastener used to maintain the relative position of two or more components within the machine. By compressing upon insertion into a hole, the pin exerts outward pressure against the walls to provide a secure fit without the need for threads. This component is specifically sized at 10 mm in diameter and 45 mm in length.

This pin is compatible with the Terex HC230 crawler crane. It is utilized in various assemblies, such as control systems, articulation mechanisms, and gear supports, to ensure that parts remain properly aligned and fixed during operation. The design allows the pin to accommodate minor variations in hole diameter while maintaining its position under operational conditions.

In heavy machinery, spring pins serve as essential fasteners for securing shafts, levers, and linkages. Their elastic nature allows them to absorb radial loads and maintain tension within a bore, which helps prevent components from shifting or vibrating loose during the cycle of crane operation.
