The loading and unloading trolley is driven and controlled by a frequency converter, with precise double positioning. The lifting mechanism is hydraulically controlled, and the lifting weight can reach 6t. The car body is made of welded profiles and plates, and the surface is covered with PP plates, which not only anti-corrosion but also improves the service life of the frame finishing. For equipment manufacturers that rely on forklifts or trucks for loading and unloading, it can improve logistics efficiency and reduce labor costs, and can be individually modified.
