C2 Series articulated trucks feature more power and increased payloads

T he new Cat C2 Series articulated dump truck range includes the 234 kW 725C2 and the 274 kW 730C2 and 730C2 EJ with ejector-type body. Rated payloads are 24 t for the 725C2 and 28 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.

The Cat 6F/1R power-shift transmission electronically modulates clutch engagement pressures and incorporates the Caterpillar APECS system.

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.

All three new C2 Series models feature full-time, six-wheel drive. Also, new for the C2 range is all-axle wet brakes. The sealed system prevents the ingress of debris and extends brake life.

The new C2 Series models feature field proven major structures that ensure long term durability in severe applications.

The newly design dump body, using Brinell HB450 wear-resistant steel for added resistance to impact and abrasion, features a diverging flow design that promotes clean dumping and minimizes material carry-back. The body top rail design reduces material spillage in the loading area, and a fully welded front bumper and full-width belly pan provide enhanced machine protection.

To promote safe operation, the cab features integral ROPS/FOPS construction. An electro-hydraulic secondary steering system automatically activates in low pressure situations. The park brake is spring applied, hydraulically released. External switches for fuel cut-off and electrical disconnect are easily accessible outside the machine.

The optional Cat Production Measurement system brings payload weighing to the cab.

Part of Link technologies, the Product Link system wirelessly connects owners to their equipment, providing access to valuable machine data such as location, hours, fuel consumption, idle time, events, and diagnostic codes via the online VisionLink user interface.
