Cat has launched three new articulated trucks, the 730, 730 EJ (Ejector), and 735, which have been extensively redesigned to enhance the features and performance of their C-Series predecessors (730C2, 730C2 EJ, and 735C).
The new trucks have new operator stations, including new controls, transmission-protection features, new hoist-assist system, advanced traction control system, new stability-assist system, and a fuel saving ECO operating mode. In addition, the design of the 730 and 730 EJ is enhanced with automatic retarder control and a hill-start feature. The 735 retains these features from its C-Series predecessor and further incorporates significant design refinements that include a new Cat C13 ACERT engine, Cat CX31 transmission (also on the 730 and 730 EJ) and structural and dimensional modifications that reduce empty weight by 22%, while retaining the productivity of the outgoing 735C. According to Cat, these features combine for up to 19% gain in fuel efficiency.
The new 735 replaces the Cat C15 ACERT engine, rated at 441 net horsepower, with the Cat C13 ACERT, rated at 428 net horsepower. The new 730 and 730 EJ continue to use the Cat C13 ACERT engine, rated at 367 net horsepower. The C13 engine used in all the new trucks is available in configurations to meet emissions standards of both highly-regulated and lesser-regulated countries.
The cab’s new external “spinal-ROPS” design incorporates a rear-quarter glass that eliminates a structural pillar in the C-Series design, for enhanced rear visibility. Also, a new “wake-up” feature initiates the machine’s displays when the door is opened. The door is of a lighter, stronger design with a shut-assist feature for improved sealing against dust infiltration. The overall cab design results in lower inside sound levels at 72 dB(A), a 7 dB(A) reduction compared to previous models.
