High-temperature environments hoist Precautions

1, the operation of electric hoist cab shall be closed, but it should be equipped with fan or air-conditioning.
2, the motor windings and the cabinet should be buried thermistor temperature control device,hoist and trolley when the temperature exceeds a certain limit, the power to protect or stop the motor strong cold additional measures.
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, 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.
5, lifting the motor and run the motor insulation class Class F and lifting the motor windings built with overheating protection device.
6, rope configuration metallurgy occasion dedicated high strength high temperature resistant wire rope.
In addition to these high-temperature environment precautions,lever hoist the electric hoist fundamental issues should also be noted, do not overload the use, the use of the hoist Please read carefully before using the instructions and precautions.

Electric hoist more widely used in the field of environment, under normal circumstances the ambient temperature between -20 ℃ ~ +40 ℃,chain Block but with the expanding range of use in many high-temperature environments hoist pay special attention to the following matters:
