Description

Technical Field

[0001] This invention relates to the field of overhead guard technology, and more particularly to a modular forklift overhead guard. Background Technology

[0002] Forklifts are usually equipped with a split cab, which is a cab with an overhead guard as its frame. Due to market demand, split cabs need to be equipped with air conditioning and heating systems.

[0003] The existing cab overhead support structure for installing air conditioners and heaters involves directly welding the mounting brackets to the overhead support. However, this structure has two drawbacks: First, due to the unique nature of the existing overhead support, different structural specifications of overhead supports are required when installing air conditioners, heaters, or other components. This necessitates preparing and purchasing multiple overhead supports for different components, increasing the overall operating cost of the forklift. Second, if subsequent modifications to the overhead support installed on the cab are needed, the welding process will make such modifications difficult. Therefore, providing a modular forklift overhead support is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] One object of this invention is to provide a modular forklift overhead guard that reduces the number of overhead guards to purchase and prepare when using forklifts, thereby reducing the cost of later forklift modifications.
