Problems solved by technology

[0002] At present, in the process of building construction, mechanical equipment is often required to lift building materials. Tower cranes are only suitable for occasions where the space between floors is relatively large. For occasions with small spaces, large equipment such as tower cranes cannot lift building materials at all. In actual construction During the process, it is necessary to use manual handling to place the building materials to the desired location, which is not only labor-intensive, but also very low work efficiency

Abstract

The invention relates to a crane, and belongs to the technical field of lifting devices. The free rotation crane comprises a pedestal, a crossbeam is fixed to the pedestal, one side of the pedestal is provided with two elongated cylinders, the front portion of the pedestal is provided with a sleeve, the upper end and the lower end of the sleeve are fixedly connected with a first flange and a second flange respectively, two sides of the second flange are connected with one end of the pedestal and the crossbeam through bolts respectively, two sides of the sleeve are in strengthened connection with the pedestal through a front support and a rear support respectively, a supporting rod is sleeved in the sleeve, a first bearing is arranged between the top of the sleeve and the supporting rod, a second bearing is arranged between the bottom of the sleeve and the supporting rod, and one side of the supporting rod is provided with a platform. The free rotation crane has the advantages of labor intensity reduction, great work efficiency increase, small occupied space, and suitableness for construction in a narrow space.

Description

technical field [0001] The invention relates to a hoisting machine and belongs to the technical field of hoisting equipment. Background technique [0002] At present, mechanical equipment is often required to lift building materials during construction. Tower cranes are only suitable for occasions where the space between floors is relatively large. For occasions with small space, large equipment such as tower cranes cannot lift building materials at all. In actual construction In the process, it is necessary to manually transport the building materials to the required position, which is not only labor-intensive, but also very low in work efficiency. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art, and to provide a free-rotating hoist with reasonable structure design, simple and convenient operation, low labor intensity and high work efficiency. [0004] The present invention is achieved ...
