Metallurgical electric hoist casting
Metallurgical electric hoist casting environment
1, metallurgical electric hoist working level M6, the working environment temperature is not higher than 60 ℃.
2, the hoisting mechanism is equipped with two support brakes and a safety brake. The first level for the tapered rotor motor magnetic tension brake that is working brake, the second level for the reducer input and installation of the friction dry head brake to prevent the first level of failure and can continue to load the normal lift system move. Safety brake is installed on the drum assembly Emergency brake emergency brake device to prevent damage to the mechanism of the emergency transmission of the emergency state of the emergency brake can stop the drum, to prevent the load caused by the accident fall.
3, the upper limit position of the second limit device. The first time for the conventional electric hoist on the next stroke limiter limit, the second time for the vertical limit.
4, the host heat radiation protection, sub-ah electric hoist reel shell installed under the installation of the whole insulation board, with two pieces of metal sheet filled with high temperature asbestos material to isolate the high temperature of molten metal radiation.
5, lifting motor and running motor insulation class using H-class, and in the lifting motor winding with overheating protection device.
6, wire rope with 6 × 37S + IWR-GB8918-2006 high strength and high temperature important use of wire rope.
7, electrical control device set to zero pressure protection, loss of pressure protection, wrong phase protection box over current protection, control equipment, cable ZR + -YCP group of heavy-duty rubber cable.
8, the control mode using remote control, can also be used centralized control.
