(1)Technical feasibility demonstration. The comparison of several hoisting methods, from the advanced feasibility, safety and reliability, economic application, local conditions, etc.
(2) Security analysis. Hoisting work should be safety first, must combine the concrete situation, carries on the safety analysis to each technical feasible method from the technical, discovers the unsafe factor and solves the method and analyzes its reliability.
(3) Progress analysis. Hoisting work often restricts the progress of the whole project. Therefore, it is necessary to analyze the duration of different hoisting methods, and the method adopted can not affect the progress of the whole project.
(4) Cost analysis. To carry out minimum cost accounting for safety and schedule, and obtain reasonable profit.
(5) Make a comprehensive choice according to the specific situation.
