Description

Technical Field

[0001] The utility model belongs to the technical field of hoists, and in particular relates to a drive axle mounted hoist. Background Art

[0002] The drive axle is a mechanism at the end of the drive train that converts the speed and torque from the transmission and transmits them to the drive wheels. A drive axle typically consists of a final drive, differential, wheel drive mechanism, and drive axle housing. Steering drive axles also have constant velocity joints. Drive axles also withstand vertical, longitudinal, and lateral forces acting between the road surface and the vehicle frame or body, as well as braking torque and reaction forces. Drive axles are commonly installed on vehicles such as automobiles, harvesters, and tractors. During drive axle installation, a crane is required. Currently, most cranes used for drive axle installation utilize a wire rope and hook to hoist the drive axle. The crane travels along a track, and the hook runs along the crane's crossbeam to maneuver the drive axle into position. During maneuvering, the suspended wire rope can cause the drive axle to swing, posing a risk of unhooking. Furthermore, the crane cannot effectively position the drive axle during assembly. Furthermore, the installation and operation costs of the crane are relatively high, requiring significant capital investment.

[0003] In view of this, the present utility model is proposed. Utility Model Content
