ChinaProduct Description Double girder gantry crane are mainly
consists of Girder frame, Crane travelling device, hoist as the
lifting device and electrical parts, it is designed with working
grade of A5~A8 according to the use frequency. Bridge adopts box
welded structure, high degree of vertical and horizontal rigidity.
It has a strong beam and a stable travelling mechanism; the
emergency switch can stop any movement once any dangerous happened.
It is rely on the bridge frame along the workshop rail direction
moves forward-backward, the hoisting mechanism can be hoist type or
winch type according to the lifting capacity and working demand.
The trolley along the main beam direction moves left-right and the
hook lift up-down. FEM design The European
type double girder gantry crane is designed according to DIN/FEM
standard with stepless lifting speed and cross travelling speed and
long travelling speed. Light weight design The European
type double girder gantry crane is more advanced on structure
design. The crane self height is 20%-25% lower than normal overhead
crane, the self weight can be 20%-30% lighter, the wheel press can
be 15%-20% smaller, the hook limit will be smaller so the working
space will bigger. Moreover, the light crane structure can reduce
the workshop cost. Modular design The component parts of
crane are designed into various series standard modulars. And
different modulars can be assembled to different products. All
the modular components all can assembly and disassembly for good
transportation. Standard modular components can be
manufactured with short producing time and steady quality. So that
we can short the delivery time. Advanced manufacturing
technology Both side of all the steel plate of crane are
pretreatment by pretreatment production line, Sand blasting--
Primer spray--Primer drying. Eliminate the inner stress of steel
plate, increase the adhesive force of the steel structure. Ensure
the appearance and anticorrosion quality. Steel plate cutting
adapt whole sets Messer CNC plasma cutting machine from Germany,
very fast cutting speed, little deformation, High precision,
Deviation could be controled within 1mm, it insure the raw material
at high quality standard and can reach top level in the
industry. The welding of main beam adapt high efficiency and
intelligent welding robot, Weihua are 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. The welding of main beam
adapt radiographic inspection and ultrasonic flaw detection for the
welding joint and fillet weld position. High
security Overload limit monitor, it can shows the loading
capacity and help the operator to avoid overload. Automatic
checking system, the controller can check the effectiveness of
power voltage, the of default Phase protection device and zero
position of all buttons. Up and down double lifting limit
switch, when the hook reach the limited position, the crane will
shut off the power automatically and will reposition by itself.
Also it can make the motor work on the opposite way to avoid
attacking the crane girder. Wire rope is imported from
Germany, the breaking force is no less than 2160KN/mm2 and safety
factor no less than 5. High
reliability Motor. Motor is imported from Germany, the
insulation class is F class, the protection class is IP54. The
motor has overheat protection device and warning function. The
motor box is of Ardal material which has good radiating
performance. Reducer. Reducer is imported from Germany, which
can improve the loading ability with the hard gear. The gear box
has a perfect leak tightness which can avoid oil leak. Main
electric unit. Main electric unit is Siemens, ABB, Schneider brand,
the protecting class is no less IP54. Wheels. Wheels are
forged by 65Mn steel, which is very wearable and using life is very
long. Low-energy & free-maintenance With
Germany motor, the total power can be 20% lower than normal crane,
which can save energy. Compositive transmission mechanism has
less mid device, the efficiency can be higher. Frequency
control speed, the can be low-high speed 1:10, which will improve
the working efficiency with more than 20%. Free
maintenance+easy maintenance design will reduce the maintenance
cost for you. Components which are imported from abroad, the
break down rate is very low and will reduce your cost when using
the crane. Technical specificationModel numberMG - Double
