The invention discloses a shear fork type aloft work platform with a high-stability driving and steering function. The shear fork type aloft work platform is characterized by comprising a driving chassis and a lifting device; the driving chassis comprises a chassis body, a driving device and a supporting leg structure; the lifting device comprises a shear fork type lifting structure and a working platform; the shear fork type lifting structure comprises an upper shear fork unit, a lower shear fork unit and a lifting oil cylinder. Through the small-width upper shear fork unit, on the premise of ensuring the lifting height, by decreasing the thickness of the upper shear fork unit, the weight borne by the lifting hydraulic cylinder is reduced, and the efficiency and safety of the device are improved; through the large-width lower shear fork unit, the supporting stability is ensured; the stability and synchronism of the steering process are improved; by forming pits in a steering bent plate, the steering bent plate can be closer to a wheel carrier shaft, and therefore the steering angle limit can be improved, and the use performance is enhanced.
