The maintenance platform is connected to the mobile chassis through the scissor-type lifting mechanism. A lifting device is provided on the maintenance platform. The lifting device includes several gantries and I-beams. Adjacent gantries are arranged at intervals. The I-beam is arranged on the top of the gantry. The maintenance platform is extended from both ends of the I-beam. A lifting equipment is hung on the I-beam, and the lifting equipment moves along the I-beam.
