Power Train ­ Engine Electronically controlled Caterpillar engines with ACERT technology, modular radiator with 9 fins per inch, and an Electronic Control Module maximizes power to the cutting edge and exceptional haul road speed. 4 ® Power Train ­ Transmission Planetary powershift transmission delivers excellent load capability. Redesigned front and rear axles accommodate wider brake shoes and drums. The neutral coast inhibitor and programmable top gear reduce wear while increasing machine performance. [. . . ] Convenient storage location includes space for a lunch box and first aid kit. The cab also has a cup holder as well as an ashtray. · 8 Visibility. Hood and front shroud width increased to accommodate the low emission engine, the air-to-air aftercooler (ATAAC), ether starting aid, and lights. Hood corners are sloped to maintain the same level of visibility as the E-Series. Simple and easy to operate, the joystick enhances the productivity of operators of all skill levels. Requires less force to control the critical scraper functions and requires less lever travel. Grab handle/ hand rest next to joystick controller so operator has a place to rest hand while on the haul and return roads. 1) Bowl (forward & back) 2) Ejector (side to side) 3) Thumb rocker switch · Apron position · Elevator direction, speed 4) Transmission Hold 5) Cushion Hitch 6) Trigger* (not shown here ­ is on front of joystick) · Auger (on/off) · Push-Pull (bail up/down) · Elevator (on/off, resume) * Standard open bowl does not have a trigger 1 (Down) 4 5 3 2 (Forward) 2 (Return) 1 (Up) Instrument Display Panel. Features a quad-gauge layout showing engine coolant temp, transmission/torque converter oil temp, fuel level, and system air pressure. The 627G tachometer can monitor either front or rear engine speeds. Once the 627G tractor engine has been started, the operator can start the rear engine from inside the cab. EMS III can display both front and rear engine information right in the cab. Frequently used switches and indicator lights are on the instrument panel, and less frequently used switches on the overhead console. Engine Speed Lock Controller. Enhances operation during long haul cycles by allowing the operator to maintain a desired engine speed without maintaining pressure on the accelerator. Simplifies gear selection (1st, 2nd, Drive and Reverse) and allows operator-defined top gear control. Relocating the gear control to the rear increases operator legroom. 9 Structures Superior structural design and construction optimize performance and reliability. 1 2 3 4 5 6 7 8 Load cylinder Hitch castings Scraper gooseneck Nitrogen accumulators Orifice Oil from tractor hydraulic system Leveling valve Free floating pistons Cushion Hitch. The electronically actuated cushion hitch incorporates a parallelogram-type linkage for exceptional strength with nitrogen accumulators to deliver a smooth ride for enhanced operator comfort. · · · controlled oil flow dampens rebound oscillation leveling valve automatically centers piston in cylinder for all loads steel castings are used extensively to eliminate many welded joints and increase strength double-kingbolt design withstands high external forces and simplifies installation and removal 3 2 4 · 4 1 5 7 8 6 8 Nitrogen Accumulators. Vertically mounted hydraulic cylinder transfers road shocks to nitrogen accumulators. Nitrogen accumulators absorb and dampen road shocks, thus preventing these loads from being transmitted to the operator. An operator-selectable lockout switch, located on the joystick, locks the cushion hitch for improved control of the cutting edge during loading and dumping. 10 Scraper Bowl Designed for optimum loading, material retention and ejection. Redesigned Bowl. Excellent productivity with a 10% increase in bowl capacity, improved draft arm protection, and better load retention.
