The structure is simple, eliminating maintenance difficulties. Furthermore, because both pallet lifting welding frames are connected to electrical equipment via cable chains, simultaneous lifting and lowering of both pallets and assembly of components is possible in actual production. This solves the problem of uneven weight distribution that may occur when two welding frames share a single welding frame, improving safety and stability. Attached Figure Description
