The new Cat 730C2 has a rated payload of 28 tonnes.
The 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 tonnes for the 725C2 and 28 tonnes 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.
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.
Equipment Africa says: To improve productivity, the optional Cat Production Measurement system brings payload weighing to the cab, helping operators work more productively and accurately. The integrated system calculates payload values using sensors located on the walking beam suspension and shows when target weight is reached, thus maximizing payloads and productivity.
