Proven Cat engines provide the power and torque rise for excellent lugging in tough loading conditions.
Variable horsepower comes standard and increases engine performance by setting injection timing to the optimum at every speed and load point.
The torque rise provides high lugging force during acceleration and less down-shifting on grade or in rough underfoot conditions.
The fuel system and Electronic Control Module on the 3412E tractor engine and 3408E scraper engine economically and precisely deliver fuel.
High injection pressures, independent of engine speed, decrease smoke and emissions while improving response.
Variable injection timing and duration improve fuel efficiency and cold starting, decrease smoke and emissions.
Injection rate shaping reduces emission and engine noise.
Fewer mechanical parts in the fuel system improves reliability.
Electronic control provides automatic altitude deration and automatic air filter restriction deration.
Neutral start control prevents engine from starting unless transmission is in neutral.
Throttle back-up provides the operator with a preset engine speed control in the event of a throttle input failure.
The HEUI (Hydraulic Electronic Unit Injection) is a unique and proven high-pressure, direct injection fuel system.
HEUI (Hydraulic Electronic Unit Injection) fuel system incorporates rate shaping technology which modifies the heat release characteristics of the combustion process for significant decreases in combustion sound and emission levels.
Directional shift management prevents the operator from shifting out of neutral when engine rpm is above a preset level.
Controlled throttle shifting increases drivetrain life by reducing the fuel injection rate just prior to shifting.
Automatic ether starting aid greatly improves cold weather starting.
Electronic ground level shutoff enables the operator to stop the engine from the ground with the flip of a switch.
Steel spacer plate between the block and head eliminates the need for counterbores and helps prevent associated cracking problems.
Oil-cooled pistons and full-length water-cooled cylinder liners provide maximum heat transfer for longer component life.
The aftercooler lowers intake charge air temperature to increase power and reduce thermal stresses that can cause premature wear of pistons, rings, and liners.
Engine oil cooler maintains optimum oil temperature for proper cooling and longer lubricant life.
Laminated thermal-shield improves tractor protection by reducing the temperature of exposed engine surfaces, cools engine and operating compartments, extends hose and wiring life.
Eight-speed power shift transmission provides automatic, on-the-go shifting for simple, reliable operation.
Neutral coast inhibitor control helps prevent the transmission from shifting to neutral at speeds above 8.1 km/h (5 mph).
Top gear control helps prevent shifting above a programmed gear to better regulate haul road speeds.
Electronic Programmable Transmission Control (EPTC II) records both current and intermittent faults.
The standard retarder can extend brake life.
Check engine indicator informs the operator of engine conditions and aids in problem diagnosis.
The Caterpillar electronically controlled cushion hitch design dampens shocks to provide a smoother ride.
Electronic rocker switch located on the multi actuates cushion hitch from within the cab.
Electronically controlled cushion hitch locks down for positive control of the cutting edge during loading and dumping.
Double kingbolt design withstands high external forces and allows easy installation and removal.
Extensive use of steel castings eliminates many welded joints, making a strong hitch.
Wide cutting edge scoops large volume loads from shallow cuts, while the low-profile design of the bowl offers less resistance to incoming materials.
Cellular construction adds strength and dent resistance to bowl sides and floor.
Steel router and edge supports, floor plates and high-abuse components are tempered for strength.
Cat bulldozer ejection system combines constant spreading control with bowl-cleaning efficiency.
Angled top plate on ejector helps retain load.
Quick drop bowl lowers bowl quickly. Carry check safety feature helps prevent bowl dropping in case of line failure.
Bowl ejector and apron feature box section design with integral casting, increasing dent-resistance wear life and overall rigidity.
Apron design is curved and carries approximately one-third of the load to better utilize space and enhance loading.
Coal bowl is available, offering increased volume for use with light-weight materials.
The auger is able to handle a wider variety of materials compared to conventional elevating scrapers.
The auger eliminates the need for a large support fleet.
The auger has a single hydraulic system for the entire machine with separate implement pumps/valves.
Minimal parasitic loss due to auger increase hydraulic demand.
A slip limiter switch prevents rear wheel spin during loading.
The auger arrangement is ideally suited for landfill applications.
The auger improves material mixing for greater compaction in the dump area.
The auger minimizes dust and noise during loading.
The auger mechanism is hydraulically driven and controlled by a switch on the apron lever in the operator's compartment.
Standard rubber-mounted cab reduces noise and vibration for comfortable, shift-long operation.
Low-effort controls are easily accessible for sure, precise operation.
Hydraulic servo-steering system provides low-effort automotive feel and excellent maneuverability.
Tilt steering column adjusts to five different positions for operator comfort and control.
A suspension seat delivers a comfortable ride.
The Electronic Monitoring System checks important machine systems and provides a three-level warning.
The operator's station includes radio compatible wires in the cab.
Multifunction bowl lever gives operators the ability to control important scraper functions without removing their hands from the bowl lever.
Engine overspeed indicator light and alarm sound when the engine rpm exceeds 2700.
Standard air conditioning keeps operator comfortable and productive. The turn signals in the cab are also standard.
Scraper-mounted fuel tank improves access to tractor engine compartment.
Improved wiring harness incorporates color coded and numbered circuits for quick identification, minimum 10-amp fuses and improved connectors.
Diagnostic connector, with the aid of a service tool, allows quick analysis of the starting and charging circuits.
O-ring face seals help keep these machines 'dry'.
Centralized lubrication blocks for the hitch and steering reduce lube time.
Service points for the engine are grouped on the right side for easy access.
Service platforms and numerous handholds improve access and safety.
Increased component commonality with other Caterpillar scrapers/machines improves parts availability.
Electronic ground-level engine shut-offs for convenient operator and services areas.
The optional retarder extends brake life when working on severe, downhill slopes.
Extensive use of castings in the frame, hitch and bowl provide long service life.
Rounded off bumpers reduce hooking into high walls.
Standard tires provide the maximum flotation of the available options.
Laminated Thermo-Shield helps keep surface temperatures in the engine compartment below the flash point of diesel fuel.
