Description:
LDA model single girder EOT crane is a kind of light duty crane, with the capacity of 1 to 20 tons. The span is 7.5to 31.5 meters. Working duty is A3 A4. Working environment temperature is -20°C to 40°C.
LDA model single girder EOT crane consists of main beam,end beam,electric hoist,festoon cable and electric control system,It is widely used in plants, warehouse, and material stocks to lift goods.
LDA model single girder EOT crane is matched with electric hoist which is CD model or MD model.
It is prohibited to use the equipment in the combustible, explosive or corrosives environment.
Mechanical Parts：
1.Double 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.
