Abstract
Relevance of applying factory-assembled unit installation method in the contemporary construction is stated. Foreign experience is shown and main foreign manufacturers of crawler cranes and gantry cranes are given. Basic technical characteristics and design parameter of foreign and domestic cranes are quoted. The experience of gantry crane usage is discussed. Technical characteristics of gantry cranes from Sarens, Enerpac, Riggers Manufacturing, LiftSystems, Hydrolast, and Enerprom are given.
Highlights
The main direction in the contemporary construction is dry construction of civil and industrial buildings and facilities allowing their fast erection at minimal labor cost on the construction site
The comprehensive installation process consists of a number of steps, which are performed in sequence from delivery of prefabricated elements to the construction site and their assembly into a finished facility according to the design documentation and method statement
During installation using comprehensive construction and process blocks, process equipment and engineering lines are mounted onto construction structures
Summary
The main direction in the contemporary construction is dry construction of civil and industrial buildings and facilities allowing their fast erection at minimal labor cost on the construction site. The comprehensive installation process consists of a number of steps, which are performed in sequence from delivery of prefabricated elements to the construction site and their assembly into a finished facility according to the design documentation and method statement. Individual structures are enlarged into flat or spatial blocks. This allows performing construction works, which are difficult to do at height, at zero level. In preparing organizational and technological documentation, the choice of installation method determines the technological sequence of installation works and largely determines the technical and economic parameters, labor productivity, quality of works, energy intensiveness, and mechanization level.
