Development of the design of a sectional boom of the vertebral type on a special chassis for construction dismantling work

Abstract

The article discusses the design of a designed flexible boom on a special chassis for dismantling construction work in cramped conditions. A detailed description of the main structural elements, their purposes, as well as operating principles is provided. Developed 3-D models of a special vehicle structure with a flexible boom designed for dismantling work. Hydraulic shears are considered as the main working equipment in this work. Technical solutions for their design for working with small construction waste, concrete structures and reinforcement are presented. Options for retrofitting with special equipment for working at different times of the day and under different conditions, both in cramped and open construction sites, are proposed. To control the flexible boom, hydraulic equipment was developed: a special hydraulic distributor and flexible shells, which together are responsible for the smooth and precise movement of the flexible boom in cramped conditions of the construction site. As conclusions, the work provides options for the practical application of the developed flexible boom design.
