19.12.2011 Caterpillar New Fuel-Efficient Motorgraders

Caterpillar presented new motor graders the Cat 120M2 and 12M2 — with their all-wheel-drive (AWD) counterparts, the 120M2 AWD and 12M2 AWD featuring low-emitting, fuel-efficient engines meeting Tier IV Interim emission standards. The new M Series 2 models have wider net-horsepower ranges than their M Series predecessors. The 120M2 and 120M2 AWD use the C7.1 ACERT engine, and the 12M2 and 12M2 AWD the C9.3 ACERT engine. Maximum net power ratings for the new models, respectively, are 189 hp (141 kW), 209 hp (156 kW), 223 hp (166 kW) and 243 hp (181 kW).

New motorgraders continue to feature Caterpillar’s control system, which uses two electronic joysticks to provide complete control of the machine, while reducing hand and wrist movement by nearly 80 percent, compared with conventional controls. The spacious M Series 2 cab, with standard air conditioning, uses angled doors and a sloping rear window to afford enhanced visibility to the heel and toe of the moldboard and to the ripper.
