Technology advantages:
Compared with the general cast iron sheave, the hot rolled steel sheave could not be broken. It replaces the traditional cast iron and cast steel sheaves, which has filled in the domestic gap. The hot rolled steel sheave is available from ∅150-1800MM, and the international advanced technology is adopted. Its advantages are：
1. It is highly resistant to tension and impact force.
2. It is resistant to wear and has large bearing load. The service life is more than 5 times of the iron pulley.
3. The pulley groove is quenched, the friction coefficient with the wire rope is small, so the service life of the wire rope is lengthened.
Industry solution
Our technology research center has researched the key part of tackle”pulley” in order to solve the disadvantages of traditional cast iron and cast steel pulley. Through repeated test, large multi-pulley singing tackle with”single-plate” hot rolled steel sheave” has been successively produced. The tackle has been applied to large projects, such as the Three Gorges, Qingdao Port, Raffles drilling platform borehole.
Quench hardening technology:
With the technology, the sheave groove is quenched and hardened. The maximum hardness is provided on the touch surface of the wire rope to resist the resistance. 140° touch area is generated with the wire rope. The steel plate surface is very applicable to quenched hardening to reduce the tolerance and fatigue and wear.
