The telescopic rod is extended by pulling it, and the angle between the telescopic rod and the axle seat 5 is adjusted. The rotating sleeve 4 is then rotated to extend the telescopic rod to the desired position. The extended sling 10 is then used to connect the cargo via the hook 11. At this point, turning the handle 12 rotates the rope roller, and pulling the sling 10 lifts the cargo. Next, the telescopic rod is rotated back into the housing 1, and the extended sling 10 is released to unload the cargo. Only minimal hand cranking force is required for stable, single-person manual lifting, making it more labor-saving and safer. Simultaneously, the flatbed trolley 2 and housing 1 can be moved using the rollers 17. Once in position, the boom 18 is rotated, and the electric telescopic rod 21 pushes the foot pads 22 downwards to support the cargo on the ground, improving stability and safety during cargo lifting.
