STS, the Ship To Shore Container crane is widely used to load and unload containers from ship and trucks. The crane frame design is very advanced so that the crane can work with a high efficiency. The trolley can travel on the rails which are mounted on the outreach beam and the whole crane travels on the rails mounted in the ground. The fast moving and lifting speed brings you excellent working performance.
STS crane is mainly consisted of steel structure, hoisting mechanism, trolley travelling mechanism, long travelling mechanism, luffing mechanism. All the mechanisms can be operated with a stepless speed by the operator in the omnibearing view cabin.
High Quality Material and Components
The steel plates of harbor crane 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 motor, gear box can be China top brand or International brand. The main electric unit can be Siemens, Schneider, ABB.
Modular Design
The components of crane are designed into various series standard modulars. And different modulars can be assemblied to different products.
All the modular components all can assembly and disassembly for good transpotation.
Standard modular components can be manufactured with short producing time and steady quality. So that we can short the delivery time.
Advanced Manufacturing Technology
Pretreat
Both side of all the steel plates of crane are pretreatment by pretreated by 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.
Cutting
Steel plate cutting adopts whole sets Messer CNC plasma cutting machine from Germany, with very fast cutting speed, little deformation, High precision, Deviation could be controlled within 1mm, it can insure the raw material at high quality standard and can reach top level in the industry.
Welding
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 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 default Phase protection device and zero position of all buttons.
The driving and driven wheels have edge brake, and the brake interlocks with the electric to avoid crane from gliding so that can improve the safety.
Weihua crane is the most famous Chinese crane brand, Weihua can also manufacture other kind of quay crane, portal crane, quay gantry crane , ship to shore gantry crane， rail mounted quay crane and so on. Weihua crane can supply quay crane operator training.
