Cantilever work vehicle height adjustment device

Abstract

A height adjustment device for a cantilever work vehicle includes: a movable frame, a guide rod, an adjustment frame, and a plurality of pads. The movable frame has a front guide wheel at its lower end and an auxiliary rod connected to one side, with an auxiliary wheel at one end of the auxiliary rod. The top of the guide rod is fixedly connected to a bracket of the cantilever work vehicle, and the bottom has a rear guide wheel. The adjustment frame has a crossbeam and a straight beam. A receiving space is formed at the perpendicular intersection of the crossbeam and the straight beam at one end of the adjustment frame, and the straight beam at the other end is connected to the guide rod. The pads are stacked on the receiving space of the adjustment frame. This device facilitates height adjustment, assembly, and disassembly for the worker when adjusting the height of the cantilever work vehicle on an ultra-high slope, and improves the safety and stability of the cantilever work vehicle during displacement and propulsion operations.
