LH double-girder crane with electric hoist consists of box-shaped bridge,trolley travelling mechanism,crab and electric equipment. It employs fixed electric hoist which is fitted on crab frame as hoisting mechanism. The crab uses LD drive to run,while the trolley adopts LD drive or QD drive. The structure,simple and convenient,features low entire height and light dead weight,so that it is applicable to operational sites of medium and small lifting load such as factories and mines, workshops and warehouse.
It has three operation modes: ground handle,wireless remote control and cab. The cab has two types:open cab and closed cab.
1. PLC+man-machine interface(optional)
2. Variable-frequency technology
3. Small space use
4. Safety and reliable
5. Energy-conservation
6. Low cost of running and maintaining

1. Double welding box girder, beam deflection with DIN/FEM standard
2. Steel Material: Chinese standard Q235B and Q345B
3. Trolley rail is made of high strength hot rolled flat steel (16 Mn)
4. Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster
5. The girder and end beam are connected together by high strength bolts to ensure the structure strength and precision of the whole machine
6. The end beams are equipped with flat wheel or double rim wheels, anti-friction bearings, buffer blocks and derailment preventing end plate
7. Maintenance walkway is located on one side of the main girder, consisting of flower pattern plate, 1050meters handrail.

1. Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible
2. Long and cross travel limited by means of preliminary and final limit switches or Wireless anti-collision device
3. Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from accidental falling
4. All movements can be switched off by actuating the emergency-off switch at the control station via a main contact
5. High quality long time bearing polyurethane materials buffer fixed at the end of trolley travelling and crane travelling to prevent over traveling
6. Safety hook latch used for avoiding the lifted material out off from the hook
7. Audible and visual alarm device to inform the person stay near by the travelling crane
8. Rain Cover for lifting mechanism of outdoor cranes, electric cabinet and driving mechanism
9. Protective earth conductor is fitted as standard
10. Voltage lower protection system
11. Current overload protection system
1. Overhead crane and gantry crane manufacturing and tolerances of rail installation GB/T10183-2005
