Operation process: lifting method (1) steel piles and precast reinforced concrete column similar. Steel columns can be used for dual-lift crane lifting method. When lifting, dual flat steel column while hanging up off the ground after a certain height suspend, remove transport flatbed truck, then opened simultaneously rotating dual brakes, hanging only by the host lifting, back straight when lifting steel columns, the withdrawal of deputy machine, separate lifting by the host, will anchor screw inserted steel piles seized fixed. (2) the beginning of the school steel columns until the vertical deviation control within 20mm, so that the crane decoupling. Its verticality test instrument with a diameter of latitude, if the deviation of heavy machinery installation company, with Jack corrected. The last correction steel column position to comply with the relevant provisions of misalignment. Then at around 10mm thick steel column was positioned fixed with welding, steel columns recal after mining machinery installation, and then tighten the anchor bolts mechanical installation, and bearing a fixed spot up and down the block, preventing the move. According to an exemplary pilot deployment of EPRI China Construction Machinery Quality Inspection Center will be the national standard "crane safety monitoring and management system" (issued) based organizations to develop appropriate test verification program, developed experimental verification apparatus, equipment and device for large crane safety monitoring and management system to conduct a comprehensive test pilot and verification report issued by experimental verification. Meanwhile sum up the paper machinery installation, and explore the law, gain experience, and to provide technical support for the further improvement of relevant standards and the smooth implementation of the follow-up work. Paper Machinery installation _ Shandong Lu trusted (authenticated) _ Laiwu mechanical installation provided by Shandong Lu mechanical equipment installation Limited.
