The new product line has five models ranging from 68 to 157 kW (92 to 214 hp).The key features of the new dozers include best-in-class drawbar pull, increased power ratings, the first selective catalytic reduction (SCR) used in a dozer, fuel savings of up to 14%, and a significantly improved operator cab. The new models are the 750M (68 kW / 92 hp), 850M (82 kW / 112 hp), 1150M (93 kW / 127 hp), 1650M (110 kW / 150 hp) and 2050M (157 kW / 214 hp).
Productivity improvement has been a focus in the new series. This has been achieved through increased engine power, the new SCR technology, a hydrostatic drive system and an advanced load management system. The load management system automatically reduces track speed, and thereby increasing torque, when a heavier load is on the blade, and increases track speed when a lighter load is on the blade. The dozer is therefore always working at optimal power and efficiency.
The M-series also meets Tier 4 Interim emission standards through the use of SCR technology. FPT (Fiat Powertrain Technologies) supply the new engines for the 850M to 2050M models. SCR is well suited to dozers as it lets the engine run at peak performance under variable loads, without compromising power or drawbar pull, which is vital for earthmoving. SCR has its key advantages as being reduced maintenance (no diesel particulate filter) and improved fuel efficiency. The 750M, which has been designed primarily for the rental market, does use cooled exhaust gas recirculation (CEGR) to achieve emission standards.
New control customisations allow the operator to match machine performance to the jobsite requirements. This includes the ability to set blade sensitivity (models 1150M to 2050M), steering sensitivity and shuttle sensitivity to smooth, moderate or aggressive. An electro-hydraulic joystick simplifies operation by providing better feel and responsiveness. A fingertip blade shake allows quick blade cleaning, and a grading mode reduces blade speed by 40% to increase accuracy. The dozers are compatible with blade control technologies from Leica Geosystems, Topcon and Trimble.
The new cab-forward design has floor to ceiling glass for good blade visibility. The sloped hood and operator position in the cab improve visibility further. The cab is sealed and pressurised to keep dust and fumes out. Other improvements to the dozer include a box-style C-frame for strength, a new cooling system and easy access from the ground for maintenance work. All new machines come with a three-year, 3,000 hour warranty. Source: www.casece.com
