YH series electric hoist for metallurgy is a metallurgy crane equipment mainly used for lifting molten metal. Its lifting capacity is less than or equal to 10t and lifting height is less than or equal to 20m. The working environment temperature is - 10℃～60℃ and relative humidity is less than 50% under the condition of 40 ℃ temperature. Electric hoist has many protection functions such as double braking,double spacing,heating insulation plate and so on. Metallurgy electric hoist is perfect light-duty metallurgy hoisting equipment that can be used together with LDY type metallurgy single girder crane and can be installed under workshop fixed suspending rail to use individually. Design and manufacture of metallurgy electric hoist meet the requirements of AQSIQ Doc#(2007)375. Other situations that lift fusion non-metallic material or hot solid metal also can refer.
