FOUR-AXLE TRUCK CRANE AND STEERING MECHANISM THEREOF

摘要

Disclosed in the present invention are a four-axle truck crane and a steering mechanism thereof. The steering mechanism of the four-axle truck crane comprises a first steering mechanism and a second steering mechanism, wherein the first steering mechanism comprises a steering gear (10) and a first driving mechanism, and the first driving mechanism connects the steering gear (10) to the first and the second axles of the four-axle truck crane; the second steering mechanism comprises a second driving mechanism, and the second driving mechanism connects the first driving mechanism to the third and the fourth axles of the four-axle truck crane. According to the four-axle truck crane and the steering mechanism thereof, all-wheel steering is achieved, the turning radii can be reduced, the maneuver performance of the four-axle truck crane can be improved and the requirement of operation in a narrow and small place can be met.
