Customizable 5~74/20t Double Beam Hook Electric Overhead Traveling Foundry Crane

Customizable 5~74/20T Double beam hook electric overhead traveling foundry crane  Product Descriptions of Hot metal lifting Double Beam Bridge Crane:QDY Type 5~74t Hook Bridge Crane is composed of boxed bridge frame, hook, crane travelling mechanism and electric system. The main hook employs a load tool as the lifting device to hoist steel ladle, the auxiliary hook cooperate with the main hook to accomplish pouring of molten steel and steel slag, and other auxiliary hoisting.Use various speed system with speed ratio as 1:10 for main mechanisms such as hoisting, trolley traversing and crane travelling. Also we can choose the suitable speed under the customer requirementMechanical parts:Double welding box girder, beam deflection with DIN/FEM standardSteel Material: Chinese standard Q235B,Q345B, and Q355EManual brush painting,One alkyd iron red primer painting, two alkyd orange enamel finish paintingEpoxy zinc-rich primer 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 plate.1. Both sides of all the steel plate of crane are pretreated by pretreatment production line,Sand blasting-- Primer spray--Primer drying. Eliminate the inner stress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and anti corrosion quality.2. Steel plate cutting adapt whole sets laser CNC plasma cutting machine from Germany, very fast cutting speed, little deformation, High precision,  Deviation could be controlled within 1mm, it insure the raw material at high quality standard and can reach top level in the industry.  3. 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 4 welding joint outside of the main beam adapt automatic submerged-arc fillet welding machine.4. The welding of main beam adapt radiographic inspection and ultrasonic flaw detection for the welding joint and fillet weld position5. The welding of end beam adapt double gun gantry submerged arc welding, highly welding quality ensure the stable quality of the crane effectively.6. 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 prebending 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.7. The wheel and wheel axle are treated 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.8.
