Product Description of QD Type double girder overhead crane
QD Double girder overhead crane is composed with Girder frame, Crane travel device, and the trolley with lifting and moving device. There are Pave the rail for the trolley move on the main girder.Assemble the moving table on the outside of the two main girder, one side is prepare for the assemble and maintenance the crane move device, another side is prepare for the assemble of the trolley conductor device.
There are full field of view Cabin suspend under the main girder, there are joint control desk or single control box packed within the Cabin, assemble the sidelong ladder between the Cabin and moving table, The main girder joint with the two side end carriage which with the joint point in the middle.
Electric Hoist Double Girder Overhead Crane With Spreader advanced designed crane for the low headroom and high lifting height demands. It has many advantages such as: Strong rigidity, light dead weight, outstanding structure design, long working lift etc. It could save your factory space and investment effectively.High lifting capacity of this crane is designed with two hooks that means two independent sets of hoisting mechanism. The main hook is used to lift heavy objects while the auxiliary used to lift light objects,the auxiliary can also be used for collaborative main hook tilting or tipping the material. However, don’t use the two hooks to lift at the same time when goods weight is over the auxiliary rated capacity.
Mechanical parts
1. Double welding box girder, beam deflection with GB/DIN/FEM standard
2. Steel Material: Chinese standard Q235B and Q345B/Q345E
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 welded together 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, 1050 meters handrail
8. Both side of all the steel plate of crane are pretreatment by pretreatment production line, Sand blasting-- Primer spray--Primer drying. Eliminate the interstress of steel plate; increase the adhesive force of the steel structure. Ensure the appearance and anticorrosion quality
9. Steel plate cutting adapt whole sets Messer CNC plasma cutting machine from Germany, very fast cutting speed, little deformation, High precision, Deviation could be controlled within 1 mm, it insure the raw material at high quality standard and can reach top level in the industry.
10. The welding of main beam adapt high efficiency and intelligent welding robot, Henan Mine Crane Co.,LTD are No.1 enterprise who adapt this high technology machine. The welding joint inside of the main beam adapt advanced MAG welding, adapt Ar+CO2 mixed protective gas, the welding joint outside of the main beam adapt automatic submerged-arc fillet welding machine.
11. The welding of main beam adapt radiographic inspection and ultrasonic flaw detection for the welding joint and fillet weld position.
12. The welding of end beam adapt double gun gantry submerged arc welding, highly welding quality ensure the stable quality of the crane effectively.
13. Adapt the steel plate rolling drum and wireless steel tube, Henan Mine Crane Co.,LTD has a set of steel plate rolling drum producing and processing line which is industry-leading level. From prepending by 1250t press machine, to Edge rolling by three-roller plate roll, at last the longitudinal joint and circumferential joint of drum are welded by automatic welding center and drum processed by heavy duty CNC horizontal machine tool.
14. The wheel and wheel axle and treating by high efficiency quenching and tempering, it can eliminate the internal stress effectively and ensure the processing precision,
The trolley frame, drum, and bogie frame and related big welding structure are treated by Annealing in the natural gas annealing furnace to ensure the Machining accuracy after welding. Henan Mine Crane Co.,LTD have car bottom natural gas annealing furnace, the furnace chamber inside size (length*width*height) is 10000mmx4000mmx4000mm, this annealing furnace can satisfy the Stress-Relieving annealing treatment after welding for the trolley frame, drum, bogie frame, balance beam, spreader and all kinds of welding structure on the crane, Only Henan Mine Crane Co.,LTD has this ability in China Crane Hometown.
15. According to the demand of customer, our crane could be equipped with the high technology anti-swing mechanism which has been apply as the patent of our Henan Mine Crane Co.,LTD group. This is work leading level technology. Henan Mine Crane Co.,LTD take the head in achieve the best and better management, best and better manufacturing, promote the further enhance for the product quality.
16. Henan Mine Crane Co.,LTD has top advanced processing and manufacturing equipment and processing technology in the crane industry all over China, at the same time, Henan Mine Crane Co.,LTD take the head in achieve the best and better management, best and better manufacturing, Try the best to ensure the Henan Mine Crane Co.,LTD product quality and satisfy the demand of customer.
Safety 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 infrared 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 and more (contact with us more details)
