Explosion-proof Electric Travelling Overhead Crane of introduction
Explosion-proof Electric Travelling Overhead Crane of all electrical machines and electric appliances of LB model blast-proof overhead crane with hook conforms to the preｓｃｒｉｐｔions of GB3836.2~2000 Blast-proof Electrical Apparatus for Explosive Atmosphere Part two: Flameproof Type; the performance of
complete machine conforms to the preｓｃｒｉｐｔions of JB/T5897–2006 Blastproof Bridge Crane.

LB crane is LD type electric single beam crane explosion-proof version, with BCD, BMD and other forms of explosion-proof electric hoist supporting use, become a rail operation of light and small crane, its applicable weight of 1-16t, applicable span of 7.5-22.5 meters, working level of A3-A5, working environment temperature in the range of -25-+40℃. This product is a general purpose crane, mostly used in machinery manufacturing, assembly, warehouse and other places with low frequency of use or less rated lifting weight. Point: short order cycle, economical; Disadvantages: The effective lifting height is relatively low, the shaking in use is relatively large, the working level is low, and it is not suitable for heavy workshops. The crane is provided with a bottom side, a control room, remote control three control forms, the control room is provided with a end face and side door two forms for users to choose to use.

LB(LBD) explosion-proof electric single beam crane has the characteristics of reasonable structure, beautiful appearance and strong explosion-proof. The whole machine is used with HB(BCD), HBS(BMD) type explosion-proof electric hoist, lifting weight 1-10 tons, span 7.5-22.5 meters, working level A3-A5, working environment -25℃ ~ +40℃.
This product is widely used in chemical factory, warehouse, material yard, with two forms of ground and driver’s cab, driver’s cab is divided into open, closed two, installation form is divided into left, right, entry direction side, end, for users to choose according to their own use.
This product is suitable for use in flammable and explosive environment. Explosion-proof class dIIBT4
This product has two operating forms of ground and operation room. The control room has two kinds of open and closed, which can be divided into two forms of left or right side installation according to the actual situation, and the entry direction has two kinds of side and end face to meet the user’s different needs.

The crane is qualified inspected by inspection unit of blast-proof product which is appointed by the state.
The crane has got Certification of Conformity of An Instrument for Explosive Atmosphere. The signs of blast-proof are Exd II BT4 and Exd II CT4 respectively.
