TRENDS IN MOBILE PLANT: MATERIALS HANDLING IN THE FUTURE

This article describes current trends in mobile earthmoving plant, especially in Australia, and indicates possible future developments. New technology not only offers benefits in lower costs per tonne, but will also extend the viability of some quarries. The major aims of machine development are improved productivity for all types of equipment and lower costs per cubic metre. Manufacturers are attempting to build machines that will suit the needs of both mining and quarrying. However, those needs do not always coincide. Quarry redevelopment can extend a quarry's life, and at the same time provide an opportunity to raise productivity and safety. Major manufacturers have now incorporated quarry ageing into their design criteria for haul units and other equipment. The key current issue in quarrying is the environment. Quarry life could be extended by major advances in reducing machine noise levels and by the real possibility of bulldozers ripping material that was previously blasted. Modern earthmoving machines are also becoming significantly safer. Future developments in earthmoving technology seem likely to bring larger, more durable machines with better control systems, more automated functions, more efficient, electronically controlled engines and transmissions, and lower noise and emission levels. Mobile handling systems will reduce cost per tonne and provide a safe working environment.
