What should be paid attention to when hoisting large equipment with bridge crane?

Lifting is a special industry, first of all, it is necessary to ensure the safety of lifting operation. Before hoisting large-scale equipment, the bridge crane should be maintained, and the wear of wire rope should be mainly checked. In line with the national standard GB/T5972-2009 "Maintenance, Installation, Inspection and Scrapping of Crane Wire Rope", a new rope should be replaced immediately. Lubricate all bearings to ensure the normal operation of the equipment. Engineers should make hoisting plans, obey the instructions of hoisting commanders and operate accurately.

The wire ropes commonly used for cranes are phosphating coated wire ropes, galvanized wire ropes, stainless steel wire ropes or plastic coated wire ropes, which are used in atmospheric environment. Manganese phosphating coated steel wire rope produced by patented technology has the longest service life, and the fatigue life of phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope. In severe corrosive environment, the hot dip galvanized-phosphating double-coated steel wire rope with outstanding corrosion resistance is preferred, and the smooth steel wire rope is being eliminated.

The phosphating coated steel wire rope (patented by China) has been phosphatized by manganese series or zinc-manganese series, and the wear resistance and corrosion resistance of the steel wire surface have all jumped. In GB/T11376-1997, the wear resistance and rust resistance of phosphating film are introduced in detail in the national standard of phosphate conversion film for metals. Oil permeates into the pores of phosphating film, which has excellent antifriction effect and effectively inhibits the wear of steel wire surface inside steel wire rope. for reference only
