Long door pin for Bucyrus 4100XPCAC

The R82321D12 long door pin serves as a mechanical fastener for access doors, hatches, and service panels on large-scale mining equipment. By securing these panels, the pin ensures that compartments remain closed during operation, protecting internal systems from environmental debris and preventing accidental opening of service areas. It is engineered to maintain a firm connection under the operational conditions typically found in mining environments.

This component is compatible with Bucyrus 4100XPCAC, Bucyrus 7495HR2, P&H 4100XPCAC, and P&H 7495HR2 mining shovels. The pin features a total length of 17 1/2 inches, allowing it to span and secure larger access points on the machine structure. Proper installation of this pin is necessary to maintain the integrity of access panels and the safety of the surrounding work area.

In heavy machinery, door pins of this type function as primary locking or alignment hardware for hinged panels. They are designed to withstand the mechanical stresses and vibrations inherent in the operation of large mining shovels, ensuring that service doors remain in their intended position throughout the duty cycle.
