Komatsu
of Japan has released the 830E-5, a 230 metric tonne capacity dump truck said
to be the most technologically advanced 240-US ton class truck the company has produced
to date. Komatsu Ltd. or Komatsu is a Japanese multinational corporation that
manufactures construction, mining, forestry, and military equipment, as well as
industrial equipment like press machines, lasers and thermoelectric generators.
Powered
by a Cummins QSK60 diesel engine rated at a standard 2500 hp (gross), and with
a 2700 hp option for greater speed on grade, it incorporates the latest engine
and drive system technology, as well as capacity and availability improvements.
According
to Jason Arthur, Komatsu's National Product Manager - Mining, the new engine
and drive system features deliver improved performance, intelligent parasitic
load control on the engine, up to 80% lower particulate matter (PM2.5)
emissions and better fuel efficiency.
"Komatsu's
830E has been a long-standing haulage solution in Australian mining for over 30
years," he said."It's developed a reputation for very high levels of
machine availability and structural integrity over its entire asset life. So,
when it was time for a model update, it was imperative to preserve these
attributes, as well as offering sustainable improvements and safety
enhancements incorporating the latest Komatsu technology - to ensure our
customers can further reduce their costs per tonne," he added.
Advances
in the engine and drive system parasitic load management on the 830E-5 reduces
fuel consumption by up to 5% compared with the previous model. Additionally,
the truck can be fitted with on-chassis after-treatment technology allowing it
to comply with stringent Tier 4 Final emissions standards.
"These
latest model improvements also reduce external noise emissions; in fact the
trucks total environmental operational footprint has been significantly reduced
compared with previous models.
"Komatsu's
robust frame design process and the enduring structural integrity of its
predecessors gave us the confidence to re-rate the new 830E-5 model with a
higher standard payload," said Arthur.
"In
addition, it has a generous option allowance that permits it to carry more than
230 metric tonnes, depending on local option configurations. And while the
830E-5 is the most technologically advanced model released to date, we've
maintained our commitment to delivering industry-leading levels of
availability, reliability, low-labour intensity maintenance, and long frame
life," he said.
Maintenance-intensity
reductions include extended-service consumable intervals, extended oil change
intervals, a maintenance-free retard control system, brushless AC motors across
the truck and flange type rims.
A
major feature of the new truck is its new-generation Komatsu cab, which Arthur
said was the largest and most comfortable available. "This is the same cab
we recently introduced on our 930E-5 truck, and it has received consistently
positive operator feedback and acceptance," Arthur said.
"With
noise levels at the operator's ear of less than 79 dBA and significantly
reduced whole-of-body vibration levels due to an improved isolated mounting
system, it meets the most demanding ergonomic requirements. It's also designed
to be completely gender-neutral, with the operating controls and interface
designed for easy and low-effort operation. And it incorporates the full range
of dispatch and visual aids that are essential for today's demanding mining
operations.
