The invention discloses a high-altitude wire crimping universal mobile base, and relates to a mobile apparatus for a pair of special high-altitude wire crimping pliers. The universal mobile base comprises a cylindrical base, a plurality of supporting pins, and universal wheels; the multiple supporting pins are uniformly and fixedly connected with the side face of the cylindrical base in a surrounding manner; one universal wheel is fixed on the bottom surface at the outer end of each supporting pin; the cylindrical base comprises a cylinder-shaped side plate and a circular bottom plate; and a nick is formed in the middle upper part, between a pair of adjacent supporting pins, in the cylinder-shaped side plate. According to the technical scheme, the high-altitude wire crimping universal mobile base can be placed in any direction when the wire with a large section of 1250 mm2 is crimped in the high altitude; the crimping pliers can move flexibly along the axial direction of the wire in the platform so as to reduce the work intensity of a high altitude wire crimping operator.
