|
Cat 3176 DITA ATAAC Engine
The innovative Cat 3176 diesel engine delivers large-engine performance from a compact engine design. The six-cylinder engine is turbocharged and air-to-air aftercooled. With high displacement and low rated speed, this engine provides excellent fuel economy and durability that can significantly reduce operating costs. |
|
Variable Horsepower (VHP)
This option automatically delivers power when it's needed. In lower gears where traction is limited, horsepower is restricted to conserve fuel. In higher gears, when the machine can use it, horsepower has been increased. VHP controls fuel injection characteristics to reduce fuel costs, while increasing peak torque for higher ground speeds, increased rimpull in all gears, and greater productivity. |
|
Lugging Performance
High torque output and torque rise makes the 3176 very responsive. Its superior lugging capability pulls through sudden, short-term increases in loads, reducing the need to downshift while maintaining consistent, desirable grading speeds to get the work done faster. |
|
Fuel Efficiency
Caterpillar state-of-the-art electronically controlled, computer-actuated unit injection fuel system has high injection pressure for complete, efficient fuel combustion and reduced emissions. The high compression-ratio system provides dependable cold-starting performance. The dual-filter fuel system reduces component wear. |
|
Extended Engine Life
The large bore-stroke design and conservative power rating minimize internal stresses and increase component life. The low engine speeds reduce engine wear and sound levels. |
|
Electronically Controlled
Caterpillar can maximize engine efficiency by controlling the amount of fuel injected into each cylinder. This type of control allowed our engineers to develop unique power curves specifically for motor grader applications, allowing the customer to achieve maximum power with minimal fuel consumption. |
|
Hydraulic Demand Fan
The hydraulic demand fan control automatically adjusts cooling fan speed according to engine cooling requirements. This system reduces demands on the engine, putting more power to the ground and improving fuel efficiency. |
|
Improved Torque
Power curves customized for the 14H increase peak torque for higher ground speeds and enhanced productivity. Rimpull has been increased in all gears for greater productivity. |
|
Emissions Compliant
The 14H is even more environmentally friendly than its predecessors with reductions in NOx, hydrocarbon, and particulate emissions. The Cat 3176 meets or exceeds all U.S. EPA Tier II and EU Stage II emissions control standards worldwide. |
|
Power Train
The power shift transmission takes full advantage of the powerful 3176 DITA ATAAC engine. The Variable Horsepower option uses specific torque curves for each gear range for optimum performance. Dual air system and multi-disc oil brakes assure reliable braking control. |
|
 | | Power Shift Transmission
Caterpillar transmissions are designed and built specifically for Cat motor graders. The transmission provides on-the-go, full-power shifting as well as inching capability. |
|
Direct Drive
Delivers superior fuel efficiency and "feel" of blade loads, material hardness and ground speed. |
|
Gear Selection
Eight forward and reverse speeds give the operator a wide operating range for maximum flexibility. With four gear selections below 11 km/h (6.8 mph), the operator can precisely match working speeds to job conditions for maximum productivity in earthmoving applications. Gears five, six and seven provide the optimal speed range for efficient snow removal operations. Gear 8 is designed for roading. |
|
Planetary design
Large-diameter clutch packs and oil cooling help dissipate heat, resulting in extended transmission life. |
|
Inching Pedal
The inching pedal delivers precise control of machine movements with excellent modulation and low pedal effort. This is especially important in finish grading or other close-quarter work. The ECPC allows optimum inching modulation for each specific gear, providing the operator better control and feel when inching is needed. The inching pedal has also been redesigned and repositioned for superior modulation and improved operator comfort. |
|
Dual Certified Air Tanks
Supply braking capacity to each side of the machine. This system ensures secondary braking capability in the event a failure occurs in a single brake line. The dual air system also has a large reserve for stalled-engine braking. |
|
 | | Oil-Disc Brakes
Caterpillar multi-disc brakes have a large brake surface for dependable braking capability and extended life before rebuild. |
|
Location
Brakes are located at each tandem wheel to eliminate braking loads on the power train and to reduce servicing time. |
|
Brake Reliability
The completely sealed and adjustment-free brakes are oil-bathed, air-actuated and spring-released. |
|
 | | Hydraulics
The load-sensing hydraulic system lowers power consumption and system heat. The advanced PPPC control valves provide low lever effort, balanced flow and consistent cylinder speeds for outstanding blade control. Blade float is incorporated into the blade lift valves. |
|
Load Sensing Hydraulics
H-Series motor graders use the advanced proportional priority pressure-compensating (PPPC) hydraulic valves. This advanced "triple-PC" system is unique to Caterpillar and provides superior implement control and enhanced machine performance and efficiency. |
|
Less Hydraulic Pump Demand
The load-sensing hydraulic pump doesn't run continuously under load, but operates only when needed. This lowers horsepower consumption, maximizes power to the ground and implements. It also increases fuel efficiency, reduces system heat, and extends hydraulic component life. |
|
Implement Control Valves
Designed and built by Caterpillar specifically for motor graders, PPPC valves have different flow rates for the head end and the rod end of the cylinder. This insures consistent extension and retraction properties for each cylinder, for unmatched implement control. To help maintain exact blade settings, lock valves are built into all control valves. Line relief valves are also incorporated into selected control valves to protect the cylinders from excessive pressure. |
|
Consistent Cylinder Velocities
The Caterpillar Proportional Priority Pressure-Compensation hydraulic valve gives a different flow rate when extending versus retracting many of the cylinders. Cylinder velocities are consistent in both directions. The result is a hydraulic system that provides outstanding operator "feel" and predictable system response for unmatched implement control. |
|
Low Operator Effort
The hydraulic implement controls feature short lever throws and low lever efforts in both directions. This design reduces operator fatigue and helps keep the operator alert and productive an entire shift. |
|
Controls Spaced
Properly spaced control levers and short lever throws allow the operator to easily manage multiple controls with one hand. |
|
Balanced Flow
When the operator uses several controls at the same time, flow is proportioned to ensure all implements operate simultaneously with little effect on the engine or implement speeds. If hydraulic demand exceeds pump capacity, all cylinder velocities will be reduced by the same ratio. The result is improved productivity in virtually any application. |
|
Blade Float
Blade float, incorporated into the blade lift control valves, allows the blade to move freely under its own weight. By floating both cylinders, the blade can follow the contours of the road when removing snow. Floating only one cylinder permits the toe of the blade to follow a hard surface while the operator controls the slope with the other lift cylinder. |
|
Independent Oil Supply
Large separate hydraulic oil supply prevents cross-contamination and provides proper oil cooling, which reduces heat build-up and extends component life. |
|
Heavy Duty XT Hose
The use of Caterpillar hoses throughout the machine allows state-of-the-art durability and high pressures for maximum power availability and longer hose life, reducing downtime. O-ring face seals assure rock-solid connections that maintain pressure and reduce oil leaks. Intelligent hose routing minimizes exposure to damage, increasing hose life and enhancing reliability. |
|
Optional Hydraulic Lockout
Mechanically locks all moldboard, machine, and attachment control levers during machine roading. This prevents implements from being accidentally engaged when the motor grader is travelling down the road. |
|
Drawbar, Circle, Moldboard
Flexible positioning of the tall moldboard, large throat clearance and long wheelbase improve material handling. Rugged construction and replaceable wear parts minimize operation costs. |
|
 | | Blade
The tall moldboard and large throat clearance help move material more quickly and efficiently. Heat treated moldboard rails, tough-hardened cutting edge and end bits, and large diameter bolts assure reliability and longer service life. |
|
Blade Positioning
The blade linkage design provides extensive moldboard positioning, most beneficial in mid-range bank sloping and in ditch cutting and cleaning. |
|
Blade Angle
A long wheelbase allows the operator to obtain an aggressive moldboard angle. This aggressive angle permits material to roll more freely along the blade, which reduces power requirements. This is particularly helpful in handling very dry materials, cohesive soils, snow and ice. |
|
Circle Construction
One-piece forged circle stands up to high stress loads. Raised wear surfaces prevent circle teeth from wearing against the drawbar. The 64 uniformly spaced circle teeth are flame cut and heat induction hardened to resist wear, and the circle is secured to the drawbar by six support shoes for maximum strength and durability. |
|
Replaceable Wear Items
Tough, durable nylon composite wear inserts are located between the drawbar and circle, and between the support shoes and circle. This sacrificial wear system helps keep components tight for fine grading and allows easy replacement. These inserts reduce rotational friction and extend component life. Replaceable bronze alloy wear inserts are used in the blade lift and centershift cylinder sockets, draftball surface, moldboard slide rail and tip bracket bearings. |
|
Circle Drive Slip Clutch
This standard feature protects the drawbar, circle and moldboard components from shock loads when the blade encounters immovable objects. It also reduces the possibility of the grader making abrupt directional changes in poor traction conditions, further protecting the machine, operator and surroundings. |
|
Drawbar Construction
The A-frame drawbar uses box-section design for high strength and optimum durability. The bottom face is machined to provide accurate adjustment and precise blading. |
