Audited Supplier LH type Double Girder Electric Overhead traveling Crane for hoist lifting
LH type double girder electric overhead traveling bridge crane is a type of lifting machine, a machine that moves in a circular, intermittent motion. A working cycle consists of the picking device lifting the object from the picking place, then moving horizontally to a designated place to lower the object, followed by a reverse movement to return the picking device to its original position for the next cycle.
LH type double girder electric overhead traveling bridge crane is composed of two main beams and end beams. The main beam and the end beam are rigidly connected, and the two ends of the end beam are equipped with wheels to support the bridge to run on the elevated. Rails are welded on the main beam for the trolley to run. There are more typical structural types of bridge main beams, such as box structure, four truss structure and hollow truss structure.
Compared with the QD type double-girder bridge crane :
1. The work level of LH type crane is relatively low, between A3 and A4, which is not suitable for heavy workshop work; the work level of QD type crane is relatively high, between A5 and A6, suitable for work in production workshops, warehouses, freight yards, etc. Heavy workshop.
2. The LH type crane has a compact structure, light weight, simple operation and space saving.

Mechanical parts:
1. 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 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., LTD has 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.
