Spring pin for Terex HC275

The spring pin 812169 functions within the boom angle indicator assembly of the Terex HC275 crane. This component secures moving parts within the indicator system, providing the necessary tension to ensure the mechanism remains in the correct position during crane operation. By facilitating the articulated movement of the indicator linkage, it supports the accurate tracking and display of the boom elevation angle for the operator.

This part is specifically engineered for the Terex HC275 model to ensure proper fitment and alignment within the boom angle indicator system. The design incorporates a spring-loaded mechanism that allows for secure installation and retention, preventing unwanted movement or play that could compromise the accuracy of the boom angle readings. Proper maintenance of this assembly is necessary to ensure the operator receives precise information regarding boom positioning.

Spring pins are commonly used in heavy machinery to hold components in place while allowing for controlled movement or quick release. The integrated spring provides a constant force, which is useful in assemblies that require a return action or a secure hold against vibration. By maintaining the integrity of the linkage, these pins help preserve the operational accuracy of critical monitoring systems.
