The Remarkable trackless transport cart is a highly favored transport tool currently and in the future, widely used in fields such as aerospace, metallurgy, coal, heavy industry, shipbuilding, manufacturing, etc. We design a customized differential steering trackless transfer cart for customers in the metallurgical casting industry, with a capacity of 3 tons and a capacity of 1500 * 1200. The transport of casting barrels in metallurgical casting production is carried out using a roller transport frame and clamping device, which can be docked with other workstations. The vehicle automatically transfers casting containers and uses clamping devices during the transmission process to prevent container shaking and falling. It is a highly efficient transportation equipment.
