A new design increases legroom 11%, a full 88.9 mm (3.5 in), and eliminates knee contact points.
Standard enclosed ROPS with air conditioning enhances operator comfort as well as efficiency.
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. 1) Bowl (forward & back) 2) Ejector (side to side) 3) Apron (thumb rocker switch) 4) Transmission Hold 5) Cushion Hitch 6) Trigger - Auger on/off (not shown - is on front of joystick) * Standard open bowl does not have a trigger.
Instrumentation has been relocated for optimal viewing. Real-time performance and diagnostic information is provided through the display panel.
Monitors the machine status and provides real-time information including warnings of problems identified by the EMS.
Enhances convenience by placing the frequently used switches and indicator lights on the instrument panel, and less frequently used switches on the overhead console.
Enhances operation during long haul cycles by allowing the operator to maintain a desired engine speed without maintaining pressure on the throttle.
Standard air conditioning system with improved ventilation location enhances airflow in the cab.
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.
The redesigned hood has sloped corners to maintain visibility. The exhaust has been moved to the back of the hood to increase visibility to the right side.
Electronic control module monitors air filter restriction and sends a warning message to the electronic monitoring system to alert the operator if the restriction exceeds the allowable limit.
Electronic control module activates the ether injection system during engine cranking to enhance cold weather starting.
At high altitudes the system automatically de-rates fuel delivery as a function of barometric pressure sensed by the system's atmospheric pressure sensor.
Electronic Technician displays real-time pressures, temperatures, fuel settings and diagnostic messages as well as historical information such as engine over-speeds, overheating, low oil pressure, and air filter restriction events.
Electronic controls yield a fuel savings by optimizing the timing setting for varying conditions.
Caterpillar's HEUI™ fuel system uses hydraulic electronic unit injectors, has fewer moving parts than mechanical unit injection, and requires few adjustments.
With fewer mechanically controlled parts to wear or adjust, the electronic controls reduce maintenance costs and increase machine availability.
Utilizing electronic sensors, the optimum air/fuel ratio is precisely controlled by the electronic control module during all segments of the haul cycle. This results in a reduction of smoke and particulates during cranking, starting, and acceleration.
Electronic control module automatically compensates for low alternator output at low idle to keep the batteries fully charged.
Automatically synchronizes engine speed to transmission speed during shifting to reduce power train stress, increase component life, and provide a smoother ride for the operator.
Top gear selection may be either selected by the operator or downloaded into the MAC-14 controller. Provides the flexibility to match the hauling speed of the fleet to specific job-site needs.
Electronic differential lock on the tractor helps prevent the drive wheels from spinning in poor underfoot conditions. The operator engages the differential lock, prior to wheelspin, with either the left or right foot controls located on the floor of the cab.
Allows the operator to maintain the current gear for enhanced control.
Prevents the transmission from shifting into neutral if the operator selects neutral while moving faster than 8 kmph (5 mph). Maintains oil to transmission to prevent damage.
Reduces driveline torque and transmission clutch energy when directional shifts are attempted while the engine is at high rpms.
Outboard-mounted, planetary design final drives reduce torque loads on other drivetrain components while delivering exceptional reliability in the toughest applications.
Provides cam-operated expanding-shoe type brakes, independent front and rear circuits, low air pressure audible and visual action alert indicators, and a push-button operated parking brake.
The engine has the HEUI™ fuel system which uses hydraulically actuated electronically controlled unit injectors. The 3408E diesel engine has dual horsepower capability for the tractor, and provides the power and torque rise for excellent lugging in tough loading conditions.
The electronic engine provides dual horsepower settings, which increases horsepower and provides quicker acceleration on the haul road.
Yields improved fuel economy through more precise fuel delivery and cleaner, more efficient combustion.
Utilizes advanced engine management software to monitor, control and protect the engine.
Reduces air inlet temperature for enhanced combustion efficiency, reduced emission levels, higher altitude capability, and more power.
Reduces wear on the service brakes and enhances machine control. The hydraulic retarder is internal to the power train and acts as an internal brake when going down a grade. It is engaged before going down a grade.
A modular design radiator that is less prone to plugging due to a lower fin density of nine fins per inch versus thirty-three of the previous folded core radiator.
Offers less resistance to incoming materials.
System combines constant spreading control while minimizing carryback material.
Optional attachment, helps retain material and keep it from spilling over onto the rear of the scraper.
Adds strength and dent resistance to bowl sides and floor.
May be adjusted according to job conditions. The stinger (drop down) position provides good penetration and efficient flow of material into the bowl while the level cutting edge is used for finish work. For efficient loading the thinnest edge that provides satisfactory wear life should be used.
To optimize scraper loading in various materials a wide range of G.E.T. are available.
Work alone capability with a wide material appetite ranging from overburden to laminated rock. Conditions material which promotes compaction in the fill and significantly reduces dust during loading.
Provides increased power to the auger for improved loading performance.
The auger lifts material off of the cutting edge for true self-loading capability. Material is distributed evenly throughout the bowl, resulting in consistent loads.
Prevents material spillage and retains fine material far better than an elevating scraper.
Electrically actuated hydraulic damper absorbs haul road shocks for increased operator comfort.
Full hydraulic power steering provides automotive feel with positive, modulated flow control for constant steering response.
Service points for the engine are grouped on the right-hand-side for easy access.
Sealed floor rollers eliminate lubrication.
Simplifies serviceability by removing the cab pilot valve and associated line from the cab, which provides increased cab space and reduces noise. The high efficiency electro-hydraulic pilot oil filter provides cleaner oil for the pilot system.
Incorporates color-coded and numbered circuits for quick identification and simplified troubleshooting.
Provide greater parts commonality and ease of serviceability to the wheels and brakes.
Monitors the machine status and provides real-time information to the operator including warnings of problems identified by the Electronic Control Modules.
Allow quick trouble-shooting using the Electronic Technician (ET) service tool.
