LB Type Small Overhead Crane Systems

1. Product Introduction:

 

The LB type overhead crane systems.

 

LB type small bridge crane systems is used with explosion-proof electric hoists such as BCD and BMD to become a light and small crane running on rails. Its applicable lifting capacity is 1-20t and its applicable span is 7.5 -22.5 meters, working level is A3-A5, and the working environment temperature is within the range of -25-+40℃.

 

The LB type small overhead crane systems is based on "LDA" and is based on GB3836.1-2000 "Explosion-proof Electrical Equipment for Explosive Environments" and GB3836.2-2000 "Isolated Electrical Equipment for Explosive Environments" d”》designed with reasonable structure, beautiful appearance and strong explosion-proof properties. This LB type crane systems is widely used in factories, warehouses and stockyards of chemical industry units. It has two forms: ground and driver's cab. The driver's cab is divided into open and closed. The installation form is divided into left and right. The entrance direction is divided into side and End faces for users to choose according to their respective usage conditions.

3. Component:

 

LB bridge crane systems consists of four parts: metal structure, explosion-proof electric wire rope hoist, operating mechanism, and electrical equipment.

 

Metal structure part: The main beam is made of U-shaped channel steel rolled from steel plate, then welded with I-beam to form a box-shaped solid web beam. The crossbeam is also rolled into a U-shaped channel with steel plates, and then welded into a box-shaped crossbeam. For the convenience of storage and transportation, M20 bolts (high-strength bolts) are used to connect the main beams to form a whole.

 

LB type small bridge crane systems: The explosion-proof electric wire rope hoist can lift heavy objects and move longitudinally along the main beam.

 

Operating agencies: Adopt separate drive form, drive and brake are completed by explosion-proof conical rotor three-phase asynchronous motor. The transmission adopts "one open and one closed" gear transmission, and the closed gear part borrows the reducer of the hoist to run the trolley part.

 

Electrical Equipment: There are two kinds of electrical control, the electric hoist and the whole crane are equipped with safety devices, such as lifting limit switch, end limit switch, etc.

 

4. Applicable Environment:

 

This LB type small crane systems is suitable for use in flammable and explosive environments. Explosion-proof grade dIIBT4

 

5. Wearing Parts:

 

The wearing parts of LB overhead crane systems include brake rings, rope guides, buffers, travel limiters, slings, and current collectors.

 

6. How to operate an LB type small overhead crane systems?

LB bridge crane systems has two operation modes: ground and operation room. The control room has two types: open type and closed type. It can be divided into two types: left or right installation according to the actual situation. There are two entrance directions: side and end, to meet the user's choice under various different needs.
