Overview:

HB explosion-proof electric hoist introduction:

HB type explosion-proof electric hoist is suitable for explosive mixture containing flammable gas, steam and air. HB series explosion-proof electric hoist is suitable for class IIA, IIB and IIC, and temperature groups are T1～T4 combustible, the location of an explosive gas mixture of sexual gas or steam and air. HB type explosion-proof electric hoist can be divided into B grade, C grade. HB type explosion-proof electric hoist is generally applicable to Zone 1 and Zone 2. The applicable temperature of explosion-proof electric hoist is mainly from T1-T6, reaching the maximum temperature limit of T6. Let's say DIICT4 this represents: d represents the explosion-proof type. II represents Class II explosion protection, ie, factory explosion protection. C stands for Explosion-proof Zone C, which can be used for the most dangerous areas. T4 represents the temperature group. At present, explosion-proof electric hoists use more DIICT4 ratings.
