Improved cycle times and lower cost/tonne are key benefits for the upgraded Caterpillar ADT models
has redesigned three of its ADT models, the 730, 730 EJ (Ejector), and 735. The firm says that the updates boost the proven features and performance of their C-Series predecessors (730C2, 730C2 EJ, and 735C). Improvements include operator stations with innovative 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 730 and 730 EJ now have an automatic retarder control and a hill-start feature. The 735 retains these features from its C-Series predecessor and also features the latest Cat C13 ACERT engine, Cat CX31 transmission. In addition the revised 735 has a 22% lower empty weight than its predecessor as well as 19% gain in fuel efficiency.
The cab fitted to all three models is said to be larger and more comfortable, with revised ergonomic controls and greater all-round visibility. A new lighting system illuminates the cab's entry steps and hitch area. Optional integrated payload lights provide an external indication of payload levels for the loader operator. Optional long-range, LED work lights improve visibility at night or in situations of lower visibility. New cab-mounted mirrors, including a front-visibility mirror, enhance all-around visibility for the operator.
The 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. In addition, the standard 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 is said to use the differential locks to avoid wheel spin, while a throttle-smoothing system prevents acceleration surges when travelling over rough terrain that makes keeping a steady pressure on the throttle pedal difficult.
