The invention provides a lifting tool having four rotary lifting points and a crane provided with the lifting tool. The crane comprises a bridge framework, a trolley and the lifting tool having the four rotary lifting points, wherein the number of the trolley is one, and the trolley is movably positioned on the bridge framework. The lifting tool having the four rotary lifting points comprises an upper cross beam, a lower cross beam and a rotating mechanism, wherein four symmetrical pulleys are arranged on the upper cross beam; the lower cross beam is positioned below the upper cross beam; four symmetrical lower lifting forks are arranged below the lower cross beam; the lower side of one lower lifting fork is connected with one plate hook correspondingly; the rotating mechanism comprises a driving component and a rotating lifting fork; the driving component is mounted at the upper cross beam; one end of the rotating lifting fork is connected with the driving component; the other end of the rotating lifting fork is connected with the lower cross beam; the driving component can drive the rotating lifting fork to rotate; and the lower cross beam rotates along with the rotating lifting fork.

The invention relates to an ultra-thin device for parking and taking cars through full floating mechanical hands. Two sides of a longitudinal movement trolley are symmetrically provided with full floating mechanical hands, and the ultra-thin device consists of the longitudinal movement trolley and the full floating mechanical hands symmetrically arranged on the two sides, wherein the longitudinalmovement trolley comprises an underframe, a running mechanism driving motor, a driving wheel, a driving wheel driving shaft, and a driving wheel driving gear; the full floating mechanical hand comprises a mechanical arm driving mechanism, a mechanical hand transition sliding plate, a mechanical arm, linear guide rails arranged on the inner and outer sides of a long beam on the underframe of the trolley respectively, and a swinging arm guide groove, wherein the mechanical hand transition sliding plate drives the mechanical arm to move. The device is ultra-thin, and two sets of independent fullfloating mechanical hands float freely in a set range, can be placed on a conveying trolley to form a horizontal movement type mechanical parking device, and can be placed on a stacker to form a laneway stacker type mechanical parking device without a carrying plate and a comb teeth rack; and the interbedded clear height is only 1.65 meters so that the construction investment is reduced, the structure is simple, the maintenance is convenient, and particularly the device is applicable to large mechanical garage.
