[0002] The frame is also called the beam. The base of the car is generally composed of two longitudinal beams and several cross beams, which are supported on the wheels through the suspension device, front axle and rear axle. It has sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. During the manufacturing process of the frame, since the steel frame must connect the main beam and the sub-beam through many joints, it is necessary to manually weld the various connection points of the frame.

[0003] At present, trailer frames are usually welded on welding platforms. Due to the large size of trailer frames, there are limitations in placing them on welding platforms for welding, and there will be a large number of welding dead angles. If the welding is not up to standard, it will affect the stability and pressure resistance of the frame, so the frame needs to be flipped to ensure the welding quality. For this reason, we have designed an electric trailer frame flipping platform to solve the above problems. Utility Model Content
