The main beam employs a bias-rail box-type structure and connects with the end beam by a high-strength bolt ensuring easy transportation.
Traveling mechanisms of crane and trolley adopt Europe three-in-one drive form, the harden gear face reducer has good performances in compact structure, low noise, no oil leakage and long service lite
As using a new compact trolley and high-strength material, it has small overall dimension and lightweight compared with traditional crane, which can decrease the height of factory building and reduce the cost
The modular design has a short design period and high generalization, which can improve the utilization of components
With compact structure, low clearance, small dimension and large application scope, it can improve production efficiency
Full variable-frequency control runs steadily without any impaction. Running with heavy load at low speed and light load at high speed, it can save energy and reduce consumption.
Mechanical parts
1.Single 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.
Both side of all the steel plate of crane are pretreatment by pretreatment production line,
Sand blasting– Primer spray–Primer drying. Eliminate the innerstress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and anticorrosion quality.
2.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 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.,LTDare 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 position
5.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.,LTDhas a set of steel plate rolling drum producing and processing line which is industry-leading level. From pre-bending 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 and treating by high efficiency quenching and tempering, it can eliminate the internal stress effectively and ensure the processing precision.
8.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.
