A loaded truck rolling unexpectedly doesn't give second chances. Mechanical brakes fail, air systems leak, and drivers make mistakes that put workers in danger during loading operations. Physical blocking prevents movement regardless of what happens with vehicle systems, creating the redundancy that saves lives when everything else goes wrong. Quality wheel chocks Australia handle the forces involved when tonnes of vehicle and cargo try to move on sloped surfaces. Cheap plastic versions crack under pressure, whilst properly engineered designs absorb impacts and maintain position. High-visibility colours prevent trip hazards in busy yards where workers navigate around parked vehicles constantly. Sizes range from light commercial applications through to mining equipment that requires substantial blocking capacity. Compliance officers check for adequate vehicle securing during safety audits, making proper chocks a regulatory necessity alongside their obvious safety benefits during daily o
