At present, with the development of industry, larger equipment is mostly presented in a modularized form, the time consumption for equipment manufacturing and assembling is long, and meanwhile, because the equipment is supplied in an integral frame type, the appearance of sleeve type equipment which is preassembled is mostly irregular in the field installation process. In reconstruction and extension projects, the main plant structure is not generally adjusted, the replacement work of equipment in the plant is carried out in a limited space, but because of the obsolescence of the plant main body, the original plant design is not considered for equipment updating, or the defect of height limitation of the plant is overcome, the hoisting operation height can not meet the requirement, and the hoisting operation can not be carried out in the plant. The traditional construction operation is usually completed by destroying a large-area wall body, hoisting the large-area wall body by small-angle climbing rods through hoisting machinery and prying the large-area wall body by matching personnel. This method has the following problems: 1. when equipment is hoisted in a closed factory building, the position of a hoisting machine is difficult to select, the condition that a hoisting arm of the hoisting machine is superposed with a locating central point needs to be considered, and the included angle between a crane boom and the ground is small, so that the light and heavy machinery rollover accident is easy to occur; 2. when the equipment in the limited space is installed, due to the fact that the line of sight of the hoisting machinery is not visual, misoperation of personnel is easy to occur, and manual hoisting accidents are easy to cause; 3. in the equipment replacement process, the damage amount of the plant main body is large, and the safety of the plant structure is endangered.
In addition, if the equipment to be in place is located below the horizontal elevation, the hoisting machinery cannot be matched to complete hoisting operation under the condition of limited space, and after the ground in a large range is damaged, the equipment is hauled and installed by manpower, so that time and labor are wasted, and accidents caused by the crowd injury of personnel are easy to happen.
