European Single Girder Overhead Travelling Crane 20t LDC Low Headroom 50hz

Product Description:
 
The low headroom single girder overhead crane is a light-duty material handling equipment, designed for low headroom workshop application.
The standard Lifting capacity is from 10 to 10 tons. The span is 7.5to 31.5 meters. The working grade is A3. The working temperature is -25°C to 40°C. It is matched with low headroom electric hoist, the self height of this type of hoist is lower than the normal CD MD type electric hoist, therefore, this type hoist could help to increase the lifting height at the low height building.
 
This kind of overhead crane (overhead crane) is widely used in low height factories, warehouses, material inventories and other places to lift goods. It is forbidden to use inflammable, explosive and other corrosive environments.

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.
