Slew Control Methods for Tower Cranes
Today, tower cranes are in widespread use on construction sites all around the world. An important issue that arises when operating these cranes is the oscillatory behavior that occurs during payload transportation, which can have severe effects on safety as well as accuracy of payload delivery. Due to the nonlinear nature of the rotating crane motion, controlling these oscillations is a comple...
متن کاملTOWER CRANES AND SUPPLY POINTS LOCATING PROBLEM USING CBO, ECBO, AND VPS
Tower cranes are major and expensive equipment that are extensively used at building construction projects and harbors for lifting heavy objects to demand points. The tower crane locating problem to position a tower crane and supply points in a building construction site for supplying all requests in minimum time, has been raised from more than twenty years ago. This problem has already been so...
متن کاملTOWER - Theatre of Work Enabling Relationships
In a co-located team, members typically learn from a wide range of cues about the activities of the other members, about the progress in the common task and about subtle changes in group structures and the organization of the shared task environment. Most of this group awareness is achieved without specific effort. A distributed team – even if its cooperation is based on a stateof-the-art group...
متن کاملDesign of a WSN-Based Monitoring System for Avoiding Collision of Tower Cranes
Tower cranes in large construction projects are likely to collide with other cranes close to them during the operation, which is a severe hazard to the security of the staff. Thus, a WSN-based monitoring system for avoiding collision of tower cranes is proposed. The 3D data positioning technology is used to install angle and position sensors at intervals in the cranes in order to collect positi...
