Cat 730, 730 EJ (Ejector), and 735 articulated dump trucks have redesigned operator stations. The cab has a rear-quarter glass that eliminates a structural pillar in the previous design, for enhanced rear visibility. A “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.
The ADTs have automatic retarder control and a hill-start feature.
The Cat Detect/Stability-Assist system monitors the working angle of the tractor and body, as well as the grade, and cautions the operator if the machine is approaching the set threshold angle, stopping the dump process if continued action may result in potential tipping.
The Cat Advanced Automatic Traction Control system proactively applies differential locks to avoid wheel spin, and a throttle-smoothing system prevents acceleration surges when traveling over extremely rough terrain that makes keeping a steady pressure on the throttle pedal difficult.
Optional Cat Connect PAYLOAD technology calculates payload via sensors on the walking-beam suspension, and load-status lights at all four corners of the cab roof ensure visibility to the loader operator from any angle.
The 735 (right) received structural and dimensional modifications that reduce empty weight by 22 percent, while retaining the productivity of the predecessor 735C and delivering up to 18 percent better fuel efficiency. It has a 428-horsepower Cat C13 ACERT, rated at 428 net horsepower. The 730 and 730 EJ have the same engine, rated at 367 horsepower.
The 730 EJ is designed to eject loads while traveling, providing positive dumping of the entire load, and also to work in areas with overhead restrictions and with soft underfoot conditions with improved machine stability.
