It requires 2 forklifts and 1 flatbed truck to work together; 2. There are many operators; 3. The equipment efficiency is low. The speed limit on the road in the smelter is 30km / h, which is far lower than the normal driving speed of freight trucks. The vehicles are seriously worn and have a short lifespan; 4. Long-term forklift loading and unloading consumes a lot of energy. For example, if a forklift transports 20 tons of products, plus the forklift's counterweight of 20 tons, it actually needs to transport 40 tons, which consumes a lot of energy and causes a lot of pollution.

[0003] Although there are anode plate transport vehicles, such as the anode plate transport vehicle with application number 201220675508.8, which has an anode plate clamping part on the vehicle body, the anode plates need to be hoisted by a hoisting machine when they are transported to the electrolytic cell. The anode plate transport vehicle with application number 201520699509.X adopts a vertical transportation method by installing a support plate on the ground of the transport vehicle, and installing anode plate U-shaped grooves on the support plate. Therefore, the anode plates need to be lifted and loaded during loading and unloading, and it is troublesome and laborious to unload. The anode plate transportation system with application number 201120414582.X needs to lift the anode plates to the transplanter on the transport vehicle when transferring the anode plates, which requires the cooperation of more than two workers and has low work efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a large material transfer vehicle to solve the problems raised in the above-mentioned background technology. The present invention directly lifts the anode plate and transports it through a movable U-shaped bracket controlled by a hydraulic valve. No counterweight is required.
