Metallurgy electric hoist limit function has an upper limit of the dual

1, metallurgical electric hoist working class M5, M6; operating ambient temperature not higher than 60 ℃.
2, there is a lifting mechanism configured to support brake and a safety brake, metallurgy electric hoist during normal working hours, by the conical brake motor brake,manual hoist brake motors to support conical brake, brake failure or when the conical motor intermediate transmission link fails, the high-speed shaft mounted reducer DC electromagnetic brake for heavy braking, to avoid heavy stall danger. Meanwhile, in order to coordinate the conical brake motor and the DC electromagnetic brake operation between, an additional delay in the control circuit device, to avoid traffic jam occurs motor.
3, with the upper limit dual limit function. The first limit is weight limit, the second limit of conventional electric hoist upper and lower limit stopper off the fire.
4, from the weight limit protection, electric hoist lifting 90% rated load lifting limiter alarm, 105% of rated load  lift hoist  power to stop working.
5, high-temperature insulation protection, electric hoist drum shell in the design and installation of the machine below the heat shield to isolate the molten metal heat radiation.
6, lifting the motor and run the motor insulation class using specialized metallurgical hoist used in metallurgy,wire rope winch lifting hoist molten metal industry, job level to M6. Adds a safety brake disposed directly on the roll, to the maximum security for lifting products.
