LEINA Heavy Industry can provide electric transfer carts with a load capacity of 0~500t per carts, which are particularly suitable for the transportation of large-size and large-tonnage workpieces. They can be remotely controlled and can form a fully automatic navigation AGV transportation system. They are divided into lifting type, transfer type, and load-bearing type, which can realize translation and rotation transportation in any direction in the plane. Multiple platforms can be combined and synchronously linked to form a fully automatic transportation system. With strong mobility, they can lift heavy objects to achieve precise mobile transportation, positioning docking, assembly and processing, effectively saving manpower and material resources for transportation, enhancing operational flexibility, reducing transportation risks, and promoting the overall efficiency of manufacturing plants.
