Hy-Tec Industies Austen Quarry


Like any tool, the teeth of an excavator’s bucket have a limited lifespan. In the case of the PC850 excavator at HY-TEC’s Austen Quarry, the teeth are replaced every week. Like a dentist fitting enormous veneers, quarry workers had to manually attach the five 29 kg teeth, putting the workers at risk of musculoskeletal and pinch point injuries.

In a true team effort, Hy-tec engineers, safety officers and workers developed the Excavator Bucket Tooth Exchanger. It’s a simple design that eliminates the need for a worker to handle the heavy teeth – a hydraulic arm does the heavy lifting to load the teeth into the attached tray. A forklift moves the device into position and the excavator bucket slots straight in.

"The exchanger has not only reduced the risk of injury to workers, but it made the process of changing teeth faster. Not bad for an idea that cost a little over $1000 to manufacture. We are fortunate in that our health and safety achievements and initiatives are continuously recognised within the Hy-Tec Business however, to receive recognition from an external body such as SafeWork NSW was incredibly rewarding for everyone involved", Carolyn Fisher, HSE Manager Hy-Tec.
