Problems solved by technology

[0003] Due to the need to use two trolleys, the weight of the whole crane is heavy, the limit on one side of the spreader is small, and the limit on the other side is large, and the utilization rate of the operating space is low
Moreover, the spreader cannot rotate, and the two spreaders work together when lifting the trough, and the movement track of the trough can only be translated

Abstract

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.

Description

technical field [0001] The invention relates to a hoisting crane, in particular to a rotatable crane for hoisting scrap steel troughs with four trunnions. Background technique [0002] Figure 1 to Figure 3 Shown is an existing crane for hoisting scrap steel bins, which includes a trolley 1 and a spreader 2 , and the trolley 1 can move on a bridge frame 3 . The existing spreader for lifting the scrap steel chute is usually designed as a gantry spreader, and the whole machine needs to be designed with two trolleys 1 and two sets of spreaders 2 . Each trolley 1 is correspondingly wrapped around a set of spreader 2, and jointly lifts the troughs of four trunnions. The spreader 2 includes a beam 3 , a fork 4 and a plate hook 5 . The lower part of the crossbeam 3 is connected with two plate hooks 5 through the suspension fork 4, and is used to lift the scrap steel trough. During work, the trolley drives the scrap steel trough to translate along the bridge frame 3. [0003] Due...
