Because it has a very large size and little standard structural parts, its construction time was short and there are many construction difficulties, engineers adoped the high-level assembly construction method, proper lifting machines and scientific and reliable installation methods, and these measures ens.

In this article, some high\|rise steel structural lifting methods, including choice of lifting machines, lifting method, measurement and correction of columns and beams, installment of high\|strengthen bolts, and welding of pegs of profiling steel boards, are introduced.

This paper discusses the design of concrete hardware for the monitoring and control system of large hoisting machinery based on embedded microprocessor development board EasyARM2200 and presents the software components and flowchart of programs.

Selecting and arranging hoisting machinery is one of the key tasks in boiler installation planning, which determines the difficulty and operability of hoisting, and construction schedule.
