Electric Double Girder Overhead Crane with Hook and Grab is composed with Girder frame, Crane travel device, and the trolley with lifting and moving device,Cabin and cable and electric control system. There is rails paved on the main girder for the trolley moves on the main girder.
There are walkway platform on both sides of the main girder, one side is prepared for assembly of driving motor and maintenance the crane move device, the other side is prepare for assembly of the trolley conductor device.
There are two operating methods, namely, on floor and in the driver's cabin, The cabin is divided into open-style and closed style. The cabin can be installed on the left or right according to actual conditions.The operator can enter the cabin from one side, rear or top, which depends on the different user's requirements.
The cabin is of full field of view, and it is suspended under the main girder, there are two joystick control desk installed in the cabin, to control the lifting up and down,trolley tranverse traveling and crane long traveling.
The main girder joint with the two side end carriage by welding,this design and structure is strong and robust.
Mechanical parts
Double welding box girder, beam deflection with DIN/FEM standard
Steel Material: Chinese standard Q235B and Q345B
Trolley rail is made of high strength hot rolled flat steel (16 Mn)
Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster
The girder and end beam are connected together by high strength bolts to ensure the structure strength and precision of the whole machine
The end beams are equipped with flat wheel or double rim wheels, anti-friction bearings, buffer blocks and derailment preventing end plate
Maintenance walkway is located on one side of the main girder, consisting of flower pattern plate, 1050meters handrail.
Safety protection system
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
