LEG DEVICE FOR ENGINEERING MACHINERY AND CONCRETE PUMP TRUCK

摘要

A leg device for engineering machinery comprises a swinging leg (21) hinged to an engineering machinery chassis (10), a telescopic driving device (25) and a connecting rod mechanism (27) disposed between the swinging leg (21) and the telescopic driving device (25). The connecting rod mechanism (27) is used to transfer a driving force generated by the telescopic driving device (25) to the swinging leg (21), so as to drive the swinging leg (21) to swing with respect to the chassis (10). Also a concrete pump truck.
