The manual winch is provided with a crank, and the crank is rotated to drive the traction end of the traction piece 32 to move up and down, and the traction end of the traction piece 32 can also be driven by an electric winch to move up and down in a motor driving mode.

The hoisting position of the chassis fixing frame 20 can be locked after being hoisted by the bidirectional self-locking winch 31, and compared with the overturning mode adopting a worm gear or a screw rod with self-locking, the hoisting speed is faster, and the hoisting time is saved.

In some embodiments, the traction member 32 is a traction rope or a chain.

The hauling rope may be, but is not limited to, a steel wire rope.

In some embodiments, a lifting ring 90 may be mounted on one side of the chassis mount 20, and the traction end of the traction rope or chain may be connected to the lifting ring 90. Specifically, a lifting hook can be installed at the traction end of the traction rope or the chain, and is hung on the lifting ring 90, or the traction rope can be tied on the lifting ring 90 or the chain can be welded on the lifting ring 90.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
