Brief Introduction:
Single girder overhead crane is a kind of material lifting equipment which was hung on the top of the workshop, ware house and stock ground. Both of its ends are located on tall concrete pillars or metal stents. The bridge structure lies and runs on both sides of the elevated track, This type crane can take full advantages under bridge space of lifting materials and not hindered by ground equipment It's owns the largest number used lifting machinery.
Specifications:
LD-A type electric single-girder overhead crane is designed and manufactured according to standard JB/T1306-1994. It is usually fitted with single/double speed electric hoists. Its rated lifting capacity is 1t-20t, span is 7.5m~22.5m, applicable temperature is -25° C~ +40° C, and the humidity is no higher than 85%.

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.
