When the pad 23 contacts and supports the manifold, the hydraulic locking circuit and pressure relay added to the hydraulic system can detect the measured pressure change to determine whether to stop the lifting action of the hydraulic lifting cylinder 24.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
