STS, the Ship To Shore container cranes are widely used to load and unload containers from ship and trucks. The crane frame design is very advanced so that the crane can works with a high efficiency. The trolley can travels 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, lifting speed brings you excellent working performance.

STS crane is mainly consisted by 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

 

Harbour crane steel plate 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 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

 

Pretreat

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.

Cutting

Steel plate cutting adapt whole sets Messer CNC plasma cutting machine from Germany, vrey 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.

Welding

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.

Automic checking system, the controller can check the effectiveness of power voltage, the of default Phase protection device and zero position of all buttons.

The driving and driven wheels has edge brake, and the brake interlocks with the electric to avoid crane from gliding so that to improve the safety.

 

Weihua crane is the best 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.
