Energy conservation has become the consensus of all walks of life, without affecting the efficiency of the same time, how to be more green, more environmentally friendly, it requires more thinking, more input and more practical. As for the coastal belt along the Yangtze River in China's container ports dotted-like arrangement, a more urgent action should be.

    Information indicates that the port is huge sources of air pollution. Which have become a major port equipment rubber-tyred gantry cranes (RTG) rely on their own diesel generators are configured to provide power to work on the port environment, leading to higher pollution; and a large number of ships per day by the docks in Hong Kong, ship diesel engine on the port city of pollution is very serious (see Figure 1, Figure 2).

    As the first port of Shanghai, is the port in recent years has been saving energy "pioneers" in the Hong Kong group vice president Bao Qifan, under the leadership launched a series of energy saving innovation. Bao Qifan said: "This is not only the company's own interests and development needs, but also help to improve corporate social responsibility and establish the image of Shanghai International Shipping Center."

    The transformation of RTG power supply

    RTG's own diesel generator configured to use the port will be the formation of large pollution, then the transformation of the RTG power supply has become the focus of research. Bao Qifan correspondents described in detail to the reconstruction of two ways.

    Way: oil change electric RTG

    This is mainly abandon RTG's diesel generators, for "oil change electricity", using the overhead trolley line power supply. Bao Qifan said that the site in this manner power supply system is independent from the five towers, four load-bearing rope, hanging bracket and five trolley line to form a whole structural system.

    Tower to the top position for the installation to avoid Reso, the middle bearing cable installation position, the bottom of the installation location for the trolley line. Conductor line installed height of 25.5 meters above the ground, more than all the yard crane height. Trolley line every 10 meters to install a hanging line is designed to ensure a basic level trolley line. Trolley line ends at the end with weight crosshead to prevent trolley line with the seasonal changes in outdoor temperature thermal expansion and contraction caused by changes caused by sagging degree. 20 meters from the tower is equipped with anti-sway cross arm, in windy conditions to minimize the trolley line under the swings. RTG designed and installed in the side of a platform for installation of four slide wire-guided electrical, platform height of 2 meters in order to repair and replace the corresponding parts personnel. Towers have been built around the defense wall, container trucks and other construction vehicles to prevent accidents and pose a major threat to the tower. In addition, also made of iron links to anti-static and electric shock treatment step.
