The invention discloses engineering machinery adopting a composite steering mechanism. The engineering machinery comprises a front frame and a rear frame. The front frame and the rear frame are hingedthrough a composite steering mechanism; a hinge plate is arranged at the rear end of the front frame; the composite steering mechanism comprises a hinge body; a central hinging assembly connected with a pin shaft I assembly is arranged in the middle of the front end of the hinging body; the pin shaft I assembly is connected with a hinge plate; pin shaft II assemblies are symmetrically arranged inthe left-right direction of the hinge body; and steering oil cylinders are symmetrically arranged at the rear end of the front frame in the left-right direction, the two steering oil cylinders are connected with the two pin shaft II assemblies respectively, a rear frame vertical plate is fixed to the front side of the rear frame, a sleeve is fixed to the center of the rear frame vertical plate, abush is installed in the sleeve, and a horizontal shaft diameter of the rear end of the hinge body is installed in the bush in a matched mode. The engineering machinery adopting the composite steering mechanism is simple in design and assembly, high in overall stability and capable of adapting to pavements under various complex working conditions.
