Inclined construction hoist for efficient resource transportation in irregularly shaped tall buildings

Construction hoists are essential equipment in tall building construction for the vertical transportation of construction resources. Recent increases in the construction of irregularly shaped tall buildings have created demand for a more efficient hoist operation system. This study proposes a new inclined construction hoist for efficient transportation of resources in the construction of irregularly shaped tall buildings. Tilted masts and inclination and speed control systems enable the transportation of resources without needing temporary structures to access the building, which require large cost and time inputs. In a case study, the proposed system remarkably reduced total operation costs by 26.0%, total resource transportation time by 28.8%, and time taken to the highest floor by direct transportation by 11.0% over existing systems. The proposed system will contribute to successful project completion with reduced costs in response to the current trend in tall building construction. (C) 2015 Elsevier B.V. All rights reserved.
