QJY series reducer is a kind of hard tooth surface crane reducer developed according to market demand. The whole series includes QJY (three fulcrum supporting type), QJYD (foundation installation) and QJYA (hollow shaft type) with 12 basic forms. The gear of this series reducer is made of low carbon alloy steel. The gear surface is carburized and hardened, and grinded. It has the advantages of large bearing capacity (1.8-2.4 times higher than that of QJR and qjs reducer), high transmission efficiency, reliable use and long service life. QJY series reducers are suitable for all relevant mechanisms of cranes, as well as transmission mechanisms of various mechanical equipment such as transportation, metallurgy, mining, chemical industry, light industry, etc.
