Open Winch Double Girder Overhead Bridge Crane (3-50t)

Light Duty Double Girder Overhead Crane
 
In many cases, you do not have to use a heavy duty crane, such as in a warehouse, or in a workshop where you do not often use crane, we give you a cheapter budegt solution.  The LH double girder overhead crane is the best choice.The hoist system is a wire rope hoist, and this hoist sits on a trolley.  


This designing has following advantages:

- The load capacity is bellow 50t. If more than 50t, we recommend QD winch type of crane.
- The hoist is wire rope hoist, motor self-brake.
- The work duty is A5, equal to 2m of European Rules.
- The budget is only 60% of the winch type of heavy duty crane.
- The self weight is only 50% of the winch type of heavy duty crane.  
- The CT and LT brakes are motor self brake.
- Could be double double speed by VVVF.

Technical Parameter
Charactristics
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.   
  
Technical Characteristics:
1) Hard-tooth surface of reducer
2) Steel winding drum
3) Imported rope
4) Converter function of adjustable speed without contact or module
5) Intelligence controlling
6) Trinity drive

Safety insurance:
 
1. The cranes are all equipped with weight limiters, buffer, distance limit switch, voltage protection equipment, and emergency stop system and so on.
2. The equipment is controlled by central control system.
 
Quality guaranty:
 
1. The quality of our crane would be guaranteed for one year, in this period, if any quality problem happens under correct operation, we will be responsible for repairing of replacing it for free.
