1. General
HBD flame-proof wire electric hoists is on the leading level of the samekind of products which have the advantages of construction compact, volume small, hoisting weigh large, flame-proof construction advanced, safety and reliability high and maintenace convinient.
The explosion-proof characteristic which conforms to GB3836.1-2000 < <General Requirements- - Electrical Apparatus Used in ExplosiveAtmosphere Part 1 >> and GB3836.2-2000 << Flame-proof "d"-- ElectricalApparatus Used in Explosive Atmosphere Part 2 >> can be made into flame-proof type of dIIBT4 and dIICT4. This range of motors, can used inplaces where there are explosive gas mixture in factory. The main bodycan hang on the I-steel rail for straight or curve run, or be mountedat a fixed bracket for hoisting weight.
2. Operation condition?
Elevation above sea level: less than 1,000m.
Environment temperature:-20-40℃.
Relative huminity:less than 85%(+25℃).
Duty type is S4 whose the basic load continuity is 25% and theequivalent starting times is 120 every hour.
Rated voltage: 380V, while control circuit 380V or 660V.
Rated frequency: 50Hz.
Note: The hoist is used indoors.( if used in outdoor or corrosive places, the hoist must be ordered specially.)
