Dozer drives down costs
Global equipment manufacturer Cat has launched a new dozer.
The Cat D11 features new load-sensing hydraulics and high-
horsepower reverse, combined with the latest technology to
move more material at a lower cost per ton. Engineered to be
rebuilt multiple times, the new D11 has a redesigned main frame
that delivers lower total cost of ownership over the life of the
machine. Time-saving service updates reduce daily maintenance
and boost machine uptime.
According to Cat, new load-sensing hydraulics and new drive
train components deliver up to 8% fuel efficiency gains. The
variable hydraulic pumps adjust output to meet demand, which
saves energy, reduces heat generation, and extends component
life. The new stator clutch torque divider provides improved drive
train efficiency. When combined with the new, high-horsepower
reverse function, the machine delivers 4–8% greater productivity
while burning less fuel.

Bisie opts for Osborn
Alphamin Resources, the company constructing a tin mine in
the eastern parts of the Democratic Republic of the Congo
(DRC), has ordered an apron feeder from South African-based
equipment specialist Osborn.
According to Joe Sequeira, area manager at Osborn, it is
the company’s first order to Alphamin through the venture’s
engineering, procurement, and construction management
(EPCM) contractor DRA. Sequeira says that a 1.2m × 6.5m
Osborn D4 heavy-duty apron feeder has been supplied to
the mine.
Situated approximately 180km west of Goma in the DRC’s
North Kivu Province, Bisie is considered to be one of the
largest tin deposits in the world and among the most advanced
tin projects being developed.
