Explosion-proof Lever Block





Explosion-proof Lever Block

The Scope of Application:

Can be widely used in petroleum, chainhoists petrochemical, oil station, oil depot, mining gas, chemical, military, electric power, mining, electronics, railway, environmental risk and other potential fire and explosion, in the operation of the product will not produce mechanical impact friction sparks, effectively prevent fire accidents, ensure that the national property and personal safety.

Product Characteristic:

Explosion-proof lever chain hoist is a kind of aluminum bronze, beryllium bronze as blank manual lifting machinery, the shell is made of H62 copper alloy material, the rotation gear after high temperature heat treatment to achieve the wear resistance of the gear highly explosion-proof. It the special tool is mechanical manufacturing and mechanical maintenance necessary. Explosion proof lever hoist working principle: by moving drag chain bracelet, rotating wheel start, friction ratchet wheel, brake seat (one is compressed into a common rotation axis, five) turned the gear tooth, four teeth short shaft and spline hole gear. Thus, in the device Splined gear on the sprocket driven lifting chain, smooth lifting.
