Abstract
PURPOSE: To prevent vibration of a load at the time of critical load by inputting expected load weight information to a computing device for boom deflection quantity for a crane, work radius of a boom, etc., and reducing corresponding quantity to boom deflection quantity by an expected load weight. CONSTITUTION: Prior to lifting a load 19, a sheave 16 on a crown of a jib 14 top of an innermost boom 10 of an expansion boom 6 is disposed around a vertical line passing a gravity center G of the load 19. Expected weight information of the load 19 is inputted to a computing device 30, and deflection quantity to be generated at the boom 6 and the jib 14 when the load 19 of an expected weight is suspended is computed, and a hoisting angle of the boom 6 and the jib 14 is set as θc as they are raised for a corresponding angle to the deflection quantity. After a hook of a rope 17C suspended from the sheave 16C is hooked on the load 19, the rope 17C is wound. As tension of the rope 17C increases, deflection of the boom 6C and the jib 14C is gradually increased to be at dot line positions 6D, 14C, and the sheave D is disposed around a vertical line passing the gravity center G of the load 19 at the time of the critical load.
