New Torque Anti-sway System (1)

· Through proper arrangement of guide pulleys in the horizontal and vertical direction, the movement of the four wire ropes can effectively prevent the swing of the spreader, greatly improving container hoisting efficiency.

New Torque Anti-sway System (2)

· The new-developed patented four rope anti-sway system effectively achieves bidirectional anti-sway of the spreader. This system allows a ±250mm movement of spreader in the gantry or trolley direction, greatly improving container hoisting efficiency.

Container Auto-tracking and Auto-hoisting System

· Based on the data stored from the mechanism positions and the containers on the yard as well as database management, automatic tracking operation and the most optimized tracking control of the mechanisms can be realized, increasing the working efficiency and ensuring safety.

Soft Landing of Spreader onto The Container

· Software intelligent deceleration technology and hardware inspection protection device are applied to adjust the time and position of deceleration dynamically. This helps decrease crush and wheel load, thus increasing service life and stability of the crane.

Anti-wind Anchor System

· Equipped with two independent sets of anchoring devices resisting horizontal force, four sets of ropes resisting overturning torque, four sets of anti-creeper or wheel clamp resisting gust, the system ensures the stability of the whole machine. Optional electric iron wedge, wheel clamp, rail clamp, rail jack and other wind proof devices are available.

Intelligent Rectification Technology of Gantry

· Deflection of bogie relative to the rail is detected in real-time as the control signal for the transducer to control motor speed. The bogie deflection can be corrected manually (or automatically) to prevent rail gnawing, thus ensuring sate operation, reducing wearing between wheel and rail, and span service life of crane.

Energy Recycling Technology

· Active inverter technology is applied to transfer the stored dynamic power and potential power into electricity which is recycled to the grid. Moreover, it can resist the pollution to the grid from higher harmonic voltage, thus increasing the power factor of the equipment.

Intelligent Low Voltage Capacitor Compensation

· Fully automatic resonance eliminating reactive power compensation device is configured to achieve the average power factor above 0.9, which improves electricity efficiency and reduces wire consumption.

The Preparation Process

· Complete processing equipment for steel pretreatment, cutting, bevel cutting, bending forming and other material processing are applied to provide a powerful guarantee on welding quality.

The Welding Process

· As the first semi-automatic welding assembly line for heavy port machinery, the box beam welding cycle has been shortened by 15%. By applying semi-automatic car welding of H-beam, the welding cycle of stay bar system and M-house base has been shortened by over 30%. Large structures including boom and girder can be welded completely in the factory, and the UT qualification rate is over 99%.

The Coating & Preassembly

· As the launching of new industrial park, super-large parts blasting, component painting, and assembling can be processed in the factory to guarantee the production cycle and product quality.
