A study on crane collapse in construction industry / Wan Azlinda W.Omar

A crane is a type of machine, generally equipped with a hoist, wire
ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. It uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the transport industry for the loading and unloading of freight, in the construction industry for the movement of materials and in the manufacturing
industry for the assembling of heavy equipment. One of the accidents happen in a construction site is crane collapse. Construction sites create a risk not only for the construction worker, but also for the public who move around the site or who may live adjoins them. The problem statement in this study is when cranes are wrongly constructed or operated, they may fail, crushing anything within their path. Incident crane fall in Malaysia is quite serious in the construction industry. The things such this should take serious action from the various aspects including public safety and construction workers. Although this incident is not expected to occur. The objectives of the studies are to study on crane collapse in the construction industry. Data was collected by sending a questionnaire to obtain their response on this issue such as Project Manager, Lift Operator, Crane Owner, Site Supervisor and Crane Operator. This study also to identify
the factors that contributing to the crane collapse and to recommend approaches that should be taken to reduce crane collapse. The major factor that contributes to the crane
collapse in construction industry is Management. If a Management that has been carried out properly and it will reduce the crane collapses. Besides that, all lifting equipment shall have an adequate factor of safety.
