Electric wire rope hoist overload limiter mainly plays the role is to determine when the equipment to make the electric hoist is in working condition, to make corresponding acousto-optic indicator, such as the normal state of full load hoisting, lifting state, overload equipment automation monitoring heavy state, when the overload will alarm automatically when lifting heavy objects, endless.

Electric wire rope hoist off the fire limit device is mainly used for voltage to 380V, DC to 220V, use the AC power line 50Hz. The broken fire limiter is used mainly in 0.5 tons ~10 tons of type CD1 electric wire rope hoist and MD1 electric wire rope hoist type rise, decline limit protection for. Fast direct off the main loop promotion of electric hoist.
