The Z1-50t heavy-duty AGV can provide a single vehicle with a load capacity of 50t. It has the functions of turning in place and lateral movement, and is particularly suitable for the transportation of large-sized and large-tonnage workpieces. It can operate on asphalt, self-leveling, and concrete floors, and has a strong ability to adapt to ground conditions. Because it has the function of self-lifting the entire vehicle, in addition to being used to directly carry workpieces, it can also be used to indirectly carry workpieces by drilling into the workpiece rack and self-lifting, and then lifting the workpiece rack. According to user requirements, multiple AGVs can be synchronized and used to lift super-large components. It uses laser SLAM navigation mode for fully automatic operation, and can also be operated remotely.
