Design enhancements for new Cat ADTs

Three new Cat articulated truck – 730, 730 EJ (Ejector), and 735 – have been exten- sively redesigned, enhancing the field- proven features and performance of their C-Series predecessors (730C2, 730C2 EJ, and 735C) with new operator stations, including new controls, transmission-pro- tection 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 auto- matic 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 transmis- sion (also on the 730 and 730 EJ) and structural and dimensional modifi- cations that reduce empty weight by 22%, while retaining the productivity of the outgoing 735C. These features combine for an up to 19% gain in fuel efficiency. The cab’s new external “spi- nal-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, New to HPE Africa’s range of Hyundai Earthmoving Equipment is the R260LC-9S crawler excavator, which is now available to the southern Africa market. Hyundai R260LC-9S excavators are suited for a range of sectors, including civil engineering, mining, aggregates, construction and plant hire. “Notable features of this series include advanced engine technology for high productivity, fuel efficiency and low emissions; computer aided power for optimum control of the machine and a high-strength operator cab, with good visibility for improved safety on site,” explains Alex Ackron, MD of HPE Africa. “The re-designed hydraulic system ensures fast, smooth and precise con- trol.

the passenger seat now uses a flip up/ down design and added cushioning. For added safety, a new lighting system, controlled via a ground- level switch, 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. Exterior cab features include an improved flexible lower fender and a low-profile exhaust stack that need not be removed for transport. l

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. Optional new infrared glass reduces solar heating inside the cab, and left- and right-hand sliding windows increase ventilation and facilitate communication with workers and the loading-vehicle operator. A new, auto- matic climate-control (HVAC) system positions more vents above and behind the operator for increased heating and cooling efficiency. A new heated/cooled seat is designed to give operators increased adjustments that allow “dial- ing in” personal-comfort settings; also, offer improved pump flow, which mini- mises fuel consumption, while the auto boom-swing priority function delivers maximum performance. Ground-line access to components enables easy maintenance, minimising downtime of the machine,” adds Ackron. Hyundai 9S series excavators are fitted with components designed for extended service life. Bushings have long-life lubrication intervals of 250 hours; hydraulic filters offer a service life of at least 1 000 hours and hydraulic oil offers 2 000 hours of service. Efficient cooling systems and integrated pre-heated systems extend service intervals and minimise operating costs. The new Hyundai Hi-Mate system enables users to remotely track and
