Transverse movement supporting system of precast beam erection construction machine

The utility model relates to a transverse movement supporting system of precast beam erection construction machinery. The supporting system is structurally characterized in that a plurality of groupsof lattice type shaping jig frames are fixed on a concrete strip-shaped foundation below; the adjacent lattice type shaping jig frames are connected into a whole through connecting pieces. The four steel pipe stand columns on each set of lattice type shaping jig frames are welded to two long double-spliced H-shaped steel main beams which are through in the transverse bridge direction. Longitudinal-bridge-direction short H-shaped steel distribution beams are welded to the two long double-spliced H-shaped steel main beams in the transverse bridge direction at intervals, and the guide rail beamsare fixed to the multiple longitudinal-bridge-direction short H-shaped steel distribution beams in the transverse bridge direction. A front supporting leg of the precast beam erection construction machine is placed on a front
