Steel girder string-hanging device

Abstract

The invention provides a steel girder string hanging device, which relates to the field of hoisting tools. Connect 5 sub-ropes on the rope, the sub-ropes on the two mother ropes are arranged oppositely, and the ends of each sub-rope are connected with buckles. The invention has the advantages of simple structural design, convenient use and high safety performance. It can hoist ten steel beams for one-time turnover, avoid waste of mechanical equipment with small loads, improve work efficiency, and reduce mechanical and labor costs at the same time.

Description

technical field [0001] The invention relates to the field of hoisting tools, in particular to a string hoisting device for steel beams. Background technique [0002] At present, with the rapid development of my country's economy, the development of infrastructure is also changing with each passing day. A number of large-span, large-scale factory buildings, exhibition centers, stadiums, high-rise and super high-rise projects have sprung up. Especially for high-rise and super high-rise buildings, the weight of steel beams on the same floor or plane in these projects is relatively light, but the number of identical components is large. Because of the high cornice height of such projects, tower cranes are often used for hoisting. However, in this type of project, the weight of the steel column and the steel beam is generally different. When selecting a tower crane, it is necessary to consider meeting the lifting requirements of the steel column of the largest component. Pheno...

Problems solved by technology

However, in this type of project, the weight of the steel column and the steel beam is generally different. When selecting a tower crane, it is necessary to consider meeting the lifting requirements of the steel column of the largest component. Phenomenon

If the original single machine and single root are used for hoisting, there are many shortcomings in actual operation.

For example: 1. The lifting capacity of the tower crane is relatively large, but the weight of a single steel beam is relatively light, and the phenomenon of a large horse-drawn trolley appears; 2. The hoisting of a single machine and a single root, from the starting point of the component hook to the end of the transport to the installation site, The vertical and horizontal transportation distances of the components are long, the transportation time is long, and the machinery is wasted; 3. The workers who operate the single machine and single root hoist have a long intermittent time and low work efficiency
