The utility model discloses a water -cooling stator coil welds lifting trolley comprises unable adjustment base (1), rotating face plate (2), slide rail (3), elevating gear (4), axle (5), parallel key(6), bearing (7), landing leg (8). Welding equipment makes after through the all -round rotation of this platform truck the induction coil can the correct welding position of correspondence, guarantees the welded quality, and can effectively eliminate among the welding process because of the weld bond be heated inhomogeneous result in snap, the circumstances such as deformation, and overall structure is compacter, easy narrow topography is placed, the commonality is stronger, can realize the multiple use to work efficiency can be effectively improved, the amount of labour is reduced.
