The subway gantry crane is a special gantry crane for lifting and transporting muck in subway tunnel construction. In the construction of subway tunnels, due to the space structure limitation, the excavated time tunnel, it is not for a time before the tunnel. to use a crane to lift the muck from the ground to the ground for processing. The crane has a relatively high level of work and can achieve higher work efficiency.
The main girder of the crane is an off-track box-type structure. The design adopts three-section disassembly and transportation, and through ANSYS finite element data analysis to ensure that the main girder has good rigidity and strength. At the same time, the use of anti-sway control and correction technology to ensure the safe and stable lifting process of the crane, laying a good foundation for the scientific research work of the State Grid.
China's high-speed rail business has developed by leaps and bounds in the past 10 years, and high-speed rail construction has frequently set world records and achieved world-renowned achievements. Not only that, the high-speed rail, which has the reputation of China's "diplomatic business card", is also an important carrier for the implementation of the "Belt and Road" initiative, and it bears the mission of the era of interconnection.
Mining cranes are bridge cranes installed in the hoisting machine room for installation and maintenance of hoists and their accessories. According to its working conditions, it requires a high lift, which is a super hoist crane; the hoisting mechanism has double speed, its low speed is used for installation, and the high speed is used for hoisting; the running speed should be relatively low, and ground operation
