Komatsu has released its D375Ai-8, which is the company’s first mining dozer incorporating its fully integrated Intelligent Machine Control system.
The 72.9 tonne D375Ai-8 is powered by a US EPA Tier 4 Final emission certified Komatsu SAA6D170E-7 diesel rated at 455 kW in forward gears, and 558 kW in reverse, to provide more reversing power for higher productivity.
According to Michael Hall, Komatsu Australia’s Mining Product manager, the iMC version of the dozer can carry out both bulk and final trim dozing in fully automatic mode from start to finish, delivering final grade performance and accuracy.
While this is Komatsu’s first mining machine fitted with integrated Machine Control, the concept has been successfully used on its smaller and mid-sized dozers across Australia and New Zealand over the past three years.
“The concept has been shown to significantly increase productivity and efficiency – up to twice as productive as dozers fitted with ‘bolt-on’ third party machine control systems according to Australian users and operators – while reducing the cost of each metre of material moved,” he says.
“This will deliver major benefits to mining operations across the board, whether in bulk overburden moving, chasing thin or narrow seams, for mine infrastructure works, for stockpile management, or in rehabilitation projects.
“Komatsu’s intelligent Machine Control is another step on the path to fully autonomous dozer operation.
“In addition, this technology offers significant safety benefits in stockpile applications with a remote control-ready option available.”
