Lifting rope for crane

Abstract

The invention discloses a lifting rope for a crane. The lifting rope for the crane comprises, by weight, 40-80 parts of iron, 5-10 parts of silver, 1-3 parts of zinc, 0.005-0.02 part of gold, 4-9 parts of sodium, 20-25 parts of copper, 1-5 parts of chromium, 0.5-1.5 parts of graphite, 5-15 parts of zinc oxide, 0.2-0.4 part of manganese bioxide, and 0.2-0.6 part of silicon dioxide. Break and fracture of wire are not liable to occur, abrasion resistance is achieved and the service life is long.

Description

technical field [0001] The invention belongs to the field of crane materials, and more specifically relates to a suspension rope for a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane. [0003] The main features of the tire crane are: the driving cab and the lifting control room are combined into one, which is evolved from a crawler crane (crawler crane). The shortcomings of crawler cranes (crawler cranes) that track shoes cause damage to the road surface are eliminated, and they belong to material handling machinery. The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along...
