Recently, a worker from a high-rise apartment construction site suffered a head injury, sustained from hazardous manual handling, leaving them unconscious and hospitalised after being struck in the face by a makeshift trolley.
WorkSafe report workers used a tower crane to load packs of three-metre-long metal studs into a cantilevered crane loading platform (CCLP). Then, they unloaded 4 packs at a time from the CCLP onto a makeshift trolley which was being used to move the packs of metal studs. The load then became unbalanced and slid off one end, causing the makeshift trolley to strike the worker in a catapult motion, knocking him unconscious.
