What are the safety slogans for construction cranes?

Comply with operating regulations to ensure lifting safety.

Safety first, you only live once.

Strengthen equipment maintenance to ensure safe and fast lifting operations.

Safety comes first in lifting operations.

Crane users need high-quality steel wire ropes, which should have long service life and highly stable and reliable quality. For steel wire ropes used in atmospheric environments, the main cause of wire rope failure is fretting fatigue. At present, the first preventive measure against fretting fatigue in the world's steel wire rope field is the phosphating-coated steel wire rope produced with patented technology. The rope-making steel wire has been manganese-based Phosphating or zinc-manganese treatment, the wear resistance and corrosion resistance of the steel wire surface are comprehensively improved. It is not easy to wear and corrode, which greatly improves the fatigue life of the steel wire rope. The fatigue life is three times that of the smooth steel wire rope with the same structure (under comparable conditions in the laboratory) , can be verified through fatigue testing. If you have a fatigue testing machine, do a comparative test yourself. Such test results are the most credible. The service life of the wire rope is directly proportional to the fatigue life. If the fatigue life is long, the service life will be extended in the same proportion.

Phosphate-coated steel wire ropes have a longer service life than smooth steel wire ropes, lower usage costs, and better stability. Phosphated-coated steel wire ropes are produced with patented technology. Because the supply exceeds demand, it is currently difficult to buy and more is needed. Ask several steel wire rope manufacturers. When purchasing, please note that the name of the steel wire rope, such as phosphate-coated steel wire rope, must be indicated on the purchase invoice to prevent unscrupulous companies from infringing on their legitimate rights and interests. In addition, patented products generally have a patent number on the outer packaging of the steel wire rope. Spray marking, warranty book should have main technical indicators, such as phosphate coating type and film weight (the weight, wear resistance, corrosion resistance, etc. of the phosphate film have an important impact on the service life of the wire rope), for reference only
