A busbar lifting device includes a lifting mechanism, and a lifting device for lifting the busbar is arranged on the lifting action output end of the lifting mechanism. There are left and right yokes on the body of the lifting device. When in use, the busbar can be radially clamped in the fork structure. The support surface of the stop fit is used to lift the bus bar upwards. The contact area between the lower end surface of the flange and the left and right yoke arms is large and the force is balanced, which avoids the problem of not lifting the bus bar on the common hydraulic jack in the prior art. The point of focus is that the top column of the ordinary hydraulic jack can only be in contact with one side of the lower end surface of the flange for lifting, resulting in unbalanced force on the busbar and easy to cause safety accidents.
