1. Introduction

The 1 LDA type single girder electric overhead crane is the most commen crane. It has the advantage of light deadweight, little material, low price, easy control and convenient amending.
LD type single girder electric overhead crane working class A3-A5, working ambient is from -25C to +40C.
LD type single beam electric bridge crane was recommended by WTO and apply to China standard JB/T1306-94.

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.  

Cause this is a kind of customized product,please provide us with the following information:
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?
