Description
Technical Field
[0001] The utility model relates to the technical field of forklift structures, in particular to a three-stage forklift mast adjustable-spacing fork. Background Art
[0002] A forklift mainly relies on a hydraulic lifting cylinder to hang forks of different lengths on a fork carriage to realize the towing and lifting of goods.
[0003] The forklift fork spacing refers to the horizontal distance between the forklift forks. This spacing is crucial for the stability and safety of the forklift. When operating a forklift, the fork spacing should be adjusted according to the size and shape of the goods being handled to ensure that the goods can be safely and stably lifted and transported. Due to the different usage scenarios and goods loaded and unloaded by forklifts, the ordinary forks have a single function and cannot meet the needs of diverse environments.
[0004] Therefore, in view of the above problems, a three-stage forklift mast adjustable-spacing fork is proposed to solve the above problems. Summary of the Utility Model
