What is  electric double girder overhead cranes

LH type electric single girder overhead cranes is the most commen crane. It has the advantage of light deadweight, little material, low price, easy control and convenient amending. LH type single beam electric bridge crane was recommended by WTO and apply to China standard JB/T1306-94.

LH type electric single girder crane can be divided into three parts as follow:
1. Steel structure inclueds main beam and end truck
2. Lift equipment, CD/MD or chain hoist. LD crane could have one or two speed.
3. Crane traveling mechanism: Two end carriages with wheels driven by electric motor.

Advantages
1. The quality of the main girder decides use age and use cost of the crane. "shengqi" consummately adopt European most advanced design and manufacture craft of the main girder. Mail girder wear well , not only let user ease use, but also low maintenance cost.
 
2. The up camber curve of main girder adopt optimize 4 times curve, ensure traveling have no upgrade resistance when full loading. Overcome the disfigurement of traveling motor overload traveling and trolley slide traveling.
 
3. End carriage is box girder, and the connection between end carriage and main girder adopt high strength bolt, in order to transport conveniently.
 
4. Optimize structure design, bearing layout reasonable , bear horizontal force, improve use age of the bearing.
 
5. The connections of every mechanical part are gears, in order to achieve simple installation and convenient maintenance. The drive wheel group and driven wheel group are all supported on crescent bearing box , convenient for disassembly and adjust.   
 Specification:
Can be customized.

Safety feature:
1. Limit switch.
2. Overload stop device for hoisting.
3. Long bearing buffer for crane traveling.
4. Power faliure backup.

Notice: As this kind of crane is customized, in order to offer you most suitable design and solution, please confirm following information when you send inquiry.
1. Lifting capacity.
2. Span length. (rail center to rail center)
3. Lifting height. (hook center to ground)
4. Do you need bus bar, rail from us?
5. Local power supply 380V 50Hz 3P?
6. Working condition: What goods to lift?
7. Drawings of working place would be appreciated.
