The specifications are stipulated in the instruction. The national standard requires the instruction of the manufacturer's manual.
Q:What measures should be taken to make tower cranes stable?
Increase deadweight and weight.Crane wire rope is phosphate coated steel wire, galvanized steel wire, stainless steel wire rope or coated steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment optimization of hot galvanized wire rope - double coating phosphating, phosphating coating to improve the wear resistance and corrosion resistance of steel wire that is not easy to wear and corrosion resistance is to improve the working life of the plain steel wire rope will be completely eliminated.
Q:Tower crane and construction hoist service life? What are the norms and standards? How to detect?
The tower crane service, QTZ40 state (including 40) the following ten years, more than QTZ63, the age of fifteen years, the construction elevator used for ten years; but specific to various provinces and cities are different, such as Jiangsu Province, the 40 tower crane can be used 8-10 years, QTZ63 tower crane used for 15 years, 8 years of construction hoist.
