anti-explosion single girder overhead crane specifically designed to meet explosion-proof electrical standards required in hazardous or classified manufacturing and processing areas. it mainly consists of main girder, end carriage, electric hoist, electric system. it is the most popular and pragmatic kind light lifting crane.
we are adopt the advanced technology:auto- prodution no-weld U-shape and one stop molding main girder,
Anti-Explosion single girder overhead crane standards
The anti-explosion characteristic GB3836.2-2000<< Flame-proof "d"- - Electrical Apparatus Used in Explosive Atmosphere Part 2 >> can be made into flame-proof type. This range of motors, whose explosive marking is d I, dIIAT4, dIIBT4 and dIICT4, respectively used in places where there are flammable gas and the mixture of the vapour and air in the coal minging and factory where the protection degree is IIA,IIB or IIC and temperature is T1-T4.
Duty type is M4, whose the basic load continuity is 25% and theequivalent starting times is 120every hour.
Anti-explosion form is "Exd" .
Designed, produced, checked and accepted basing on rule of GB3836-2000
The Exmark are dIIBT4 or dIICT4.
Temperature scale is Class T1-T4 mixture with explosive air (as table one and two).
