T-handle pin for National Crane 900

The T-handle pin is a mechanical component used for the manual attachment and positioning of elements within heavy machinery. It features a T-shaped handle that allows operators to insert or remove the pin by hand, facilitating efficient assembly and disassembly of equipment sections. This component is designed to provide a secure connection for various crane attachments and structural elements.

This specific part is compatible with the National Crane 900 crane model. In these machines, T-handle pins are typically utilized to secure boom extensions, counterweights, lifting accessories, or outrigger components where frequent adjustments are necessary. The cylindrical body of the pin fits into corresponding holes, while the handle acts as a stop to prevent the pin from passing through the mounting point during operation.

In general crane applications, T-handle pins serve as quick-release fasteners that maintain the alignment and stability of modular machine parts. They are often equipped with secondary locking mechanisms, such as spring-loaded balls or detents, to ensure the pin remains seated during operation. Regular inspection of these pins is standard practice to ensure they remain free of deformation or wear, which is necessary to maintain the structural integrity of the crane system.
