crane accident minimization by using android application

ABSTRACT The introduction of new Occupational Safety & Health Administration (OSHA) regulations has been referenced by organizations involved in crane operations as being a significant milestone in reducing the number of crane accidents. This study investigates the impact of the new regulations on the frequency of crane accidents that result in fatalities and injuries while identifying crane related hazards posing significant safety risk during crane operations. Crane related accidents were analyzed in detail to compare accident frequencies resulting in fatalities and injuries. Specifically, accidents were sorted by causes of crane accidents and types of crane failures. Every construction projects need machinery and equipment. Lifting and hoisting are important construction process tasks that require huge planning. Many kinds of projects, such as high-rise construction, the cranes are critical and one of the most commonly shared resources at the site. Therefore, efficient and safe operation of cranes is of the utmost importance in the safety, schedule, and overall success of the project. Mobile boom cranes are widely used to perform important tasks in various applications. Their mobility, unlike other types of the conventional cranes, provides an advantage of faster positioning. To study the tip-over stability, a tip-over prediction model is developed. The mobile boom crane model consists of four main body parts such as base, boom, height of building and payload. A crane is considered as stable when two or more wheel contact forces are positive, or making good ground contact enough to experience ground reaction forces. The prediction calculation from the prediction model are then Verified by simulation results. The outcomes are analyzed to make final conclusions about the tip-over stability of mobile boom cranes by developing an android application for the pre-construction planning to avoid crane tipping over. The prediction model and the results in the thesis provide a significant tool for practical application of tip-over stability of mobile boom cranes.
