The invention discloses a chassis and high-altitude operation equipment. The chassis comprises a central frame; the bridge expanding unit comprises supporting legs and wheel assemblies, the inner ends of the supporting legs are hinged to the center frame, the outer ends of the supporting legs are hinged to the wheel assemblies, and the supporting legs can drive the wheel assemblies to swing around the inner ends of the supporting legs along the supporting leg swing arcs; the wheel assembly comprises a wheel steering driving mechanism and a wheel rotation driving mechanism; the controller is configured to: receive a first bridge expansion command signal; controlling a wheel steering driving mechanism to drive the wheels to steer until the wheel axle sections of the wheels are tangent to the swinging arcs of the supporting legs; the wheel rotation driving mechanism is controlled to drive the wheels to walk towards the bridge expanding direction and drive the supporting legs to swing. According to the high-altitude operation equipment and the chassis thereof, the bridge expanding device is more simplified in structure, convenient and fast to assemble and install and beneficial to machining, and the cost of parts is low; the number of hinge points is small, and the control precision is higher; through detection and control of a plurality of angle sensors, the bridge expansion angle and the steering angle of the machine tire can be accurately controlled.
