Rubber tired mobile vehicles are used increasingly in underground mining. They offer flexibility, maneuverability and high productivity. However, safety does not come naturally, it has to be designed and built into these machines. The concept of designing for safety is exemplified in the load-haul-dump machine (LHD). A systems engineering approach is adopted. Safety is considered from several aspects. The machine itself -- Strength of structural components, vehicle stability, power train selection, safety in the steering, braking and other hydraulic systems, electrical systems safety. The operator-vehicle system -- Positioning of the operator station, convenient ingress and egress, good lighting and visibility, ergonomically designed instrument panels and controls to maximize operator productivity and minimize physical exertion, comfortable seating and overhead protection. The machine-environment system -- Diesel exhaust emission, noise, heat, flameproofing in gassy mines, compactness and maneuverability, radio remote control in hazardous environments.
