According to “Crane Accidents at Construction Sites in Malaysia”, crane-related-deaths is on the rise every year. Most of the fatalities are due to the operational and technical failures. As the location of the cabin is at the top of the structure, whenever there is a crane failure, the crane operator is most likely to suffer from fatal injuries, thus making this job very high risk in terms of safety. As an effort to help reduce fatalities in crane operations, wireless operation was introduced as a solution. Instead of having the cabin up in the sky, it is detached and placed on the ground. Cameras are installed to provide the same vision as if the operator is still a part of the tower crane. As such, the crane operator will be able not just to avoid danger but also increases the chance of survival in case incident.

From another perspective, we also have a vision of safety design which is more a durable and efficient tower crane by introducing a variable counterweight. Conventional tower cranes have a stationary fixed counterweight. With prolonged usage, metal fatigue will arise, and it has become one of the main factors of the tower crane’s limited lifespan. Hence, we have come up with the idea of having a variable counterweight that can be integrated in new tower cranes design as well as modified into existing jibs. With this design, stresses on the tower crane can be significantly reduced, thus enabling them to be more cost-effective as well as sustainable.
