Container transporter gantry crane, also called straddle crane or straddle carrier, is widely used in the container yard of the port. It is mainly used for transporting container from one yard to another yard.
Container Straddle Crane (Straddle Carrier) also mainly used in ship handing, large structure handing, loading and unloading. Adapt multiple lifting points combined spreader, it can satisfy all kinds of complicated operation condition required by customer. Straddle Crane can rotated 360 degree around the crane center flexible, all the hydraulic transmission mechanism and the lifting mechanism can realize stepless transmission, it can satisfy all the operating requirements in different conditions, the travelling mechanism adopts hydraulic circuit, has the advantage of high efficiency transmission and low failure rate. There is perfect safety instructions and overload protection device to ensure the safety of the operator and equipment. All the action of mechanisms are adopted can-bus control.
High Quality Material and Components
The steel plates are all from Bao steel, Wuhan steel, Handan steel, all steel should be inspected by our National Technology Test Laboratory to ensure the quality.
The generator unit is International brand and the driving, rotating, hydraulic power unit are chinese or international famous brand.
The components of straddle crane are designed into various series standard modulars. And different modulars can be assemblies to different products.
All the modular components can assemble and disassemble 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 the straddle 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.
Steel plate cutting adopts whole sets Messer CNC plasma cutting machine from Germany, wiht 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.
The welding of main beam adopts high efficiency and intelligent welding robot, Weihua are No.1 enterprise who adopts this high technology machine. The welding joint inside of the main beam adopts advanced MAG welding, adopts Ar+CO2 mixed protective gas, The 4 welding joint outside of the main beam adopts automatic submerged-arc fillet welding machine. The welding of main beam adopts radiographic inspection and ultrasonic flaw detection for the welding joint and fillet weld position.
