Specific Engineering Challenges During the Large-Scale Structures’ Mantling and Dismantling Procedures

Abstract

Mounting and dismantling of large-scale mechanical systems is a complex engineering challenge due to several factors, such as structural diversity and size of handled structures, limited maneuvering options, and absence of related literature, to name the few, all of which make each problem unique. Numerous disasters throughout the history created a need for a safe approach to the problem of executing such procedures risk-free, while preserving the structural integrity and functionality of the structures. One of the most reliable methods is the application of unique below-the hook lifting devices and the goal of this paper is to present the benefits of their use via two examples. Case 1 deals with dismounting of dated constructions in a densely populated area, with limited structural data provided. Case 2 is focused on mounting of a large-scale roof structure in harsh boundary conditions, with limited maneuvering space. Results presented in this paper represent a contribution to the field of below-the hook lifting devices.
