Product introduction

LB model explosion proof overhead crane is a kind of single girder crane specifically designed for hazardous lifting environments, usually equipped with HB explosion proof electric hoist. The motor and electrical devices of this crane are also explosion-proof type to ensure a high level of safety required for explosive atmospheres. The explosion proof single girder crane is a small overhead crane with light lifting capacity, with all the motors and electrical equipment of the explosion proof crane manufactured in line with international standards and regulations. The lifting capacity of the explosion proof single girder overhead crane is 1 to 20 tons and the working class is A3, and the specific parameters is shown in the following table.


Electric System:

1Power supply through slide lines.

2Phase protection; automatically disconnect main power when phase stagger occurs.

3The crane and hoist are mutually independent and could travel at the same time.

4Sliding contact line meets the requirement of power supplying and adapts shaking.

5Etch-proof control handle with protection degree IP54.

6Heavy-duty aviation plug.

7Electrical components are equipped in position that convenient to maintain, and with good protection to avoid inadvertent contact.

8Electric cable is suspended in cable trolley which slides flexibly and smoothly on a C-type steel.
