Cat® C2 series articulated trucks feature more power

Published by

The new Cat® C2 Series articulated dump truck range includes the 314 horsepower (234 kW) 725C2 and the 367-horsepower (274 kW) 730C2 and 730C2 EJ with ejector-type body. Rated payloads are 26.5 t for the 725C2 and 31 t for the two larger models. Standard automatic traction control ensures efficient operation of the new models, which advance the design of predecessor models with increased productivity, lower operating costs, and added rimpull/retarding capability, while retaining the long-term durability, high availability, high resale value, and optimum rental margins of previous models.

Engines in all three models are available that meet or are equivalent to world emission standards: US EPA Tier 2/EU Stage II, Tier 3/Stage IIIA, or Tier 4 Final/Stage IV. A diesel particulate filter and selective catalytic reduction system provide exhaust aftertreatment for Tier 4 Final/Stage IV models.

The Cat 6F/1R power-shift transmission electronically modulates clutch engagement pressures for smooth, positive shifts and incorporates the Caterpillar Advanced Productivity Electronic Control Strategy (APECS) system. The APECS system improves acceleration, maintains torque converter lock-up (and ground speed) during shifts, provides automatic speed holding, and modifies shift points to match operating conditions. Net benefits include high productivity, optimum control, and increased fuel economy.

For controlling downhill speed, the 730C2 and 730C2 EJ employ an engine-compression brake that provides 60% more retarding force than previous models. The 725C2 uses a fluid retarder with four operating modes. Both systems effectively manage speed and minimise service brake application for extended brake life.

All three new C2 Series models feature full-time, six-wheel drive and are equipped with wet disc clutch locks in the cross axle and inter-axle differentials. Automatic, on the go application of the locks is fully proportional, engaging only the required amount of lockup to maintain traction in adverse conditions—with no input from the operator. Also, new for the C2 range is all-axle wet brakes. The sealed system prevents the ingress of debris and extends brake life.
