Cantilever crane lifting (1) pre-assembled, the first test beam segments (especially mating surface) geometry, embedded parts location jib crane, and mark the signs point to measure the beam axis and the segment, according to Cantilevering construction requirements, the reinforcing member in the local setting, segmental temporary tension preload structure, after all the preparations in place, you can start Cantilever Erection. L # symmetrical assembly first paragraph, by the l # girder vehicle segment shipped to the bridge, hanging straight fight crane lifting, vertical position. (2) the beam segments matching filler surface coated with epoxy and cement binder, coating evenly, thickness control at 1.5mm, and the use of the coating thickness varies up and down to adjust upwards and fight cantilever crane down phenomenon, through local and temporary tensile reinforcing members pretension structure, further connected matching surface tension after wearing beam longitudinal girder segment tendons until after the next assembly cantilever crane beams, vertical tensioned prestressed reinforced . (3) Segmental when applied to vertical tensioned prestressed temporary finishing rebar, post-tensioning, grout immediately, until the next segment after the lifting of the closure of this segment of the anchor to ensure Hanging Cantilevering After the anchor force machines. (4) When the segment Cantilevering to do linear control, measuring instruments tracking, and direct contact with the lifting of command, so that timely control of cantilever beam crane hanging fight linear. Must be on linear (height, midline), etc. before and after each segment of the beam positioning accuracy measurements Column jib cranes, timely monitoring data collection and analysis, for the next section of the beam control Cantilevering provide parameters to do the next beam linear segment control. Cantilever crane jib crane for hanging pictures hollow cantilever steel structure, light weight, span, lifting capacity, economical and durable. Built-in running gear, made of special plastic with rolling bearings go round, small friction, walking briskly; small structural dimensions, particularly conducive to improving China cantilever crane hook travel company's position in the world, China has improved the production of construction machinery has accounted for half of global engineering machinery production, but compared to some of the high-end equipment with the international advanced enterprise products, there is still a wide gap. China is a big country crane jib cranes, but not the power. Chinese construction machinery cantilever crane manufacturers have cried for years "to build a world-class brand" slogan, can the status quo is not satisfactory, the crux of what? In this regard, Chen, vice president of the non-Zoomlion said, "Made in China" Machinery Products can be sold overseas in recent years, China has indicated that the quality of machinery products has been recognized by the world. The data show that China's construction machinery Crane (Column jib cranes - jib cranes crane sales and sales have leapt to the top of the world, is expected in 2012 China's construction machinery industry sales and sales growth of more than 30%, exports volume is expected to reach $ 8.5 billion - $ 9,000,000,000 .2009 September 28, Zoomlion CIFA official with the Italian company signed a merger agreement. Now, looking back, a lot more powerful than the CIFA European companies since 2008 the world's financial crisis failed. Although there are risks of overseas M & A process, but Chinese enterprises "going out" is inevitable. In addition, through cooperation with foreign companies, China's position in the world has improved. jib cranes crane _ Xinxiang Constant Crane lifting equipment (certified) _ Anyang cantilever crane lifting by Xinxiang City Constant lifting equipment Limited.
