1.2  The crane is mounted on 8 wheels with tubeless tires and powered by a diesel engine which drives an electric generator.

 

1.3  The crane is equipped with appropriate flexible hydraulic container spreader, which is connected to trolley through the upper frame and wire rope system. And the hydraulic power comes from spreader itself, and  we just provide the power supply and communication.

 

1.4 The crane is designed to travel straight along its normal path, and at right angles to that path by rotating the travel wheels through an angle of 90 degrees by electric device.

1.5 The crane is capable of handling a container load of 41 tons by means of flexible hydraulic container spreader of 10 tons, and also able to lift one 9′6″high container over five 9′6″high stacked containers and to span six rows of 8′wide containers with row distance of 400mm and a container trailer track. Effective trolley travel is 18500mm not affecting operation in stacking area.

 

1.6 Hoisting mechanism and trolley travel are able to work simultaneously or separately with load, the same applies to gantry travel and trolley travel.   

 

1.7 The Electrical drive of main working mechanism equipped with full digital AC frequency convertor, PLC speed governor and constant power adjustment device for hoisting mechanism.

 

1.8 The crane has a monitoring and management system. It has the function of data collection, analysis, management, and fault diagnosis and is also able to deliver the main parameters and operating conditions to the electrical room, cabin and control centre for monitoring and control.

 

Modular design

 

The component parts of crane are designed into various series standard modulars. And different modulars can be asseblied to different products.

All the modular components all can assembly and disassembly for good transpoftation.

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.
