Analysis of organizational features of the work of assembly cranes in cramped conditions construction

Abstract

The possibilities of placing erection cranes in cramped conditions are considered. The factors for determining the type of crane and the conditions for its operation at the construction site are given. The principles of determining the conditions of tightness of the construction site in accordance with the regulatory documentation are shown. The possibilities of limiting the boundaries of the dangerous zone of the crane are considered. The designs of various cranes are analyzed from the point of view of their placement in cramped conditions. Data are given on the features of the use of bottom-slewing and top-slewing tower cranes in the construction of civil buildings of different heights. The possibility of replacing tower cranes with fast-mounted ones during the construction of low-rise public buildings is being considered. Recommendations are given on the placement of cranes of various designs, the definition of the technological sequence of the construction of the building.
