Pemasok yang Diaudit LDP electric single-girder crane is a small-size low headroom crane. The electric hoist is at one side of the girder, which increases the workspace.
It is applicable to the places where the workshop's headroom is low.
The crane is composed of a box-shaped girder weld by steel plates, an end girder, crab frame, and a fixed electric block. The crab is partially hung and runs at one side of the g rider. The electric hoist is raised to the upside of the girder from under the girder, which effectively increases the lifting altitude.
The trolley adopts a separate drive, conical motor brake and exposed gear drive. The traveling motor can be a soft start motor and variable-frequency adjustable-speed motor according to user requirements. The crane can start steadily and runs safely and reliably.
It has three operation modes: ground handle, wireless remote control and cab. The cab has two types, open cab and closed cab. The span of it is 7.5-22 5m(subject to non-standard design according to user s requirements). The classification group is A3 and the operating ambient temperature is-25ºC~40ºC.
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,
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.,LTDhave car bottom natural gas annealing furnace, the furnace chamber inside size (length*width*heigh) 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.
