Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1-4, a span-adjustable beam lifter comprises support legs 1, a main beam 7, two sets of hoisting mechanisms 4, a steel wire rope 5 and a hanger, wherein the hanger comprises a steel wire rope 5 connecting part and a clamp 6 fixed at the lower end of the steel wire rope 5 connecting part, the clamp 6 comprises two U-shaped clamping parts capable of sliding relatively, and the upper arm 65 and the lower arm 66 of each U-shaped clamping part can also slide relatively. The span of the clamp is adjusted from the horizontal direction or the vertical direction during the use process so as to adapt to the loading and unloading lifting of beam structures with different specifications or other conventional cargos.

Specifically, the steel wire rope connecting portion comprises a fixed cross beam 62 and a steel wire rope connecting ring 61 arranged on the upper portion of the fixed cross beam 62 so as to be fixedly connected with a steel wire rope, a transverse telescopic beam 67 is arranged on the fixed cross beam 62, and two U-shaped clamping portions are respectively arranged at two ends of the transverse telescopic beam so as to be convenient for span adjustment in the transverse direction.

Specifically, a slide rail is arranged on the fixed cross beam 62 corresponding to the transverse telescopic beam 67, the transverse telescopic beam 67 is clamped in the slide rail, so that the telescopic end of the transverse telescopic beam slides along the slide rail in the telescopic process, and a telescopic switch of the transverse telescopic beam can be arranged outside the slide rail so as to be operated; reinforcing beams 63 are provided on the outer sides of the sliding rails to further improve the load-bearing capacity of the structure. The reinforcing beam can be designed into various specifications and is selected according to the telescopic length of the transverse telescopic beam, and the reinforcing beam can be fixed on the sliding rail and/or the transverse telescopic beam through bolts.
