COMPARISON OF ACTUAL VARIABLE OPERATING PRODUCTIVITY OF TOWER CRANE WORK WITH REGULATORY CONCRETE IN CONCRETE MONOLITHIC REINFORCED CONCRETE FLOOR PLATES

Abstract

buildings.

     The tower crane performs such working movements: changing the departure, lifting the boom, turning and moving the crane. Changing the departure of the boom, depending on its type, is carried out either by raising or lowering the boom, or moving the truck along the boom.

     While choosing the method of transportation and laying of concrete mixture at height, the method of "crane - bucket" is often used, which involves laying concrete mixture with buckets.

     The purpose of this work is to compare the actual variable operational productivity of the tower crane with the normative. The subject of the study is the actual variable service life and productivity of the tower crane.

     The process of concreting a monolithic reinforced concrete floor slab during the construction of a 23-stored building is investigated, the following tasks are set: 1 - brands of tower crane; 2 - the actual variable service life of the tower crane, 3 - the actual variable operating capacity of the tower crane.

     While determining the actual variable operating capacity of the tower crane was explored: the required height of the hook; the crane brand was selected; duration of a working cycle without combination and at combination of operations; variable performance of the crane at the combined and incompatible cycles; efficiency of combination of operations at work of the tower crane.
