ABSTRACT:The objective of this study provide a conceptualization for the automation of lift car operations on high-rise building construction sites, in order to build high-rise building effectively and make a proper lifting plan. We got the week point of a hand-operated lift car, and got problems of an automatic lift car up to now. And we proposed the improvement schemes considered the week points and the problems for the automation of the lift car.
Purpose The objective of this study is to develop an algorithm which can increase productivity of lift operation on temporary twin-cage and multi-cage lifts for construction sites. the algorithm is developed for optimizing operation efficiency at high-rise construction sites. Moreover, it is expected that the algorithm can reduce working hours and traffic queues through operation optimization. Method The developed algorithm can optimize lift operation time by using a lifting cycleestimating method which is generated based on the fundamental concerns when lift scheduling is planned. Lifting cycleestimation is a vital part for an arithmetic computation based on lift selection algorithm which controls factors such as distance between each lifts, among passengers, and distances among lifts according to moving direction. Results & Discussion We carried out surveys and conducted interviews with mechanical and construction professionals to analyse fundamental considerations of material lifting operation planning. We extracted the weight of each of the relevant factors. Based on the weight of factors, we set the lifting cycle-estimate suitable for high-rise buildings. The optimized operating algorithm is extracted through lifting cycle-estimates. Finally, we propose the prototype of an interface that is embedded into the lift with the optimized operating algorithm.
