More than a dozen new
Caterpillar machines made their North American debut at CONEXPO-CON/AGG 2011, including
the 140M2 all-wheel-drive grader.
The newest grader models from Cat are the 140M2 and the 160M2, along with their
all-wheel-drive (AWD) counterparts, the 140M2 AWD and 160M2 AWD. They are equipped
with engines meeting Tier 4 Interim/Stage IIIB emissions standards. The company
said that new models also deliver added value for the customer by lowering
operating costs and enhancing productivity, operator convenience and
serviceability. M Series 2 models are designed for a broad range of tasks,
including heavy blade work, road maintenance, ripping and precision-finishing
They feature emissions
reduction technology from the Cat NOx-Reduction System, which captures and
cools a small volume of exhaust gas, then returns the cooled gas to the
combustion chamber to reduce nitrogen-oxide emissions.
At the heart of the M
Series 2 design is the Cat control system, whose two electronic joysticks are
designed provide complete, precise control of the machine. The company claims
that the control system results in nearly 80% fewer hand and wrist movements
compared to conventional motor-grader controls; it says that the net result is
enhanced operator comfort and efficiency.
The new M Series 2
motor graders also feature electronic vertical adjustment of the joystick
control pods, allowing each operator to tailor joystick height. Selectable
blade lift speed modes allow more precise control to match lift response to the
Other features include optional anti-icing glass for
the windshield and right door to keep their surfaces clear in cold weather.
