Selecting the best possible cranes and identifying spatial conflict-free locations on sites can result in productivity and safety improvements for large-scale industrial construction projects. In the current practice, experienced lift engineers select cranes based on the heaviest lift and/or the largest lifting radius of the identified crane. This practice is relatively time-consuming, and opti...

The purpose of multi-tower crane motion planning is to find a collision-free construction process for multiple tower cranes operating in a construction site. This problem can be reduced to the path searching problem in highdimensional space and an important amount of research related to the path search algorithm has been published in various fields. In this paper, we analyzed the features of hi...

Intelligent tower crane has large structure deadweight. The service life of the whole machine is dependent on the life of the structure. As a result, the metal structure should be designed by using correct and reasonable methods to obtain excellent fatigue properties. And it can guide the design, manufacturing, use and maintenance process for crane. And it has great significance to prevent the ...

Today, steel tower cranes are widely used in the construction sites. In this study, the accident occurred in Turkey in 2006 with the overturning of a tower crane in a construction site and the damage occurred on the nearby buildings due to this accident were taken into consideration. At first, the technical characteristics of the EC-H type tower crane used in that construction and then the reas...

yard crane is an important resource in container terminals. efficient utilization of the yard crane significantly improves the productivity and the profitability of the container terminal. this paper presents a mixed integer programming model for the yard crane scheduling problem with non- interference constraint that is nphard in nature. in other words, one of the most important constraints in...

Due to the central role of cranes in construction operations, specialists in the construction industries have cooperated in the development of structured methods and software to help select the best crane type in construction sites. Crane selection is a time consuming process which needs extensive data exploitation. Moderately few systems have been developed to aid in selecting cranes and in se...
