Benefits & Features
Cat C11 Engine with ACERT Technology
ACERT Technology
The C11 ACERT engine introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability. The technology capitalizes on Caterpillar expertise in four core engine systems: fuel, air, electronics and after treatment. ACERT technology is a unique and revolutionary systems solution that enables Cat engines to meet today's clean air regulations, thus establishing the building blocks for attaining tomorrow's more stringent standards.
C11 Block
The one-piece, gray iron block features generous ribbing for stiffness and heavy bearing bulkheads for rigidity and strength as the crankshaft turns. Straight O-ring connection points reduce the loss of engine oil and fluids.
Cylinder Head and Piston Technology
The C11 has a cross-flow cylinder head with refined port geometry, which improves breathing and provides better combustion. The Monotherm/steel pistons have a forged steel design, which offers high strength, light weight and tighter tolerances. The result is better oil control, minimal blow-by and long liner life.
Advanced Diesel Engine Management (ADEM) A4 Engine Controller
The ADEM A4 electronic control module manages fuel delivery to get the best performance per liter or gallon of fuel used. The engine management system provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It tracks engine and machine conditions while keeping the engine operating at peak efficiency.
Fuel Delivery
Multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. This translates into more work output for your fuel cost.
Noise Reduction Technologies
Noise reduction has been achieved through design changes to the isolated top cover, oil pan, multiple injection strategy, insulated timing case cover, sculpted crankcase and gear train refinements.
Performance and Productivity – Power Train
Mechanically Actuated Electronic Unit Injection (MEUI)
A highly evolved fuel system with a proven record of reliability in the field. It combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection. It excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C11 to have complete control over injection timing, duration, and pressure.
Air-to-Air Aftercooling (ATAAC)
ATAAC keeps air intake temperatures down and, in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. Significant improvements in airflow are generated by a turbocharger, unique cross-flow head and a single overhead camshaft.
Wastegate Turbocharging
Single wastegate turbocharger provides higher boost over a wide range, outstanding low-end performance with improved peak torque and enhanced engine response.
Electronic Transmission
The Caterpillar six-speed electronically controlled transmission is designed specifically for the articulated truck and its applications. It features anti-hunt shift strategy for speed continuity.
Controlled Throttle Shifting (CTS)
Significantly reduces power train stress and clutch wear by controlling engine speed, torque converter lock-up and transmission clutch engagements.
Retarder
Integral retarder with high-power density design. Due to its compact size, the unit quickly fills with oil, providing more retarding power and fast response times.
Usable Rimpull
Power train components work together to offer more usable rimpull at higher speeds on effective grades. In first gear, the torque converter overcomes grade resistance by sending more torque to the wheels and preventing engine lugging. On downhill grades, the retarder acts like a brake by slowing the machine.
Hydraulic Fan
The remote-mounted hydraulic fan is temperature sensitive providing variable speeds when needed, which minimizes power requirements. The result is more power to the ground and faster cycle times.
Performance and Productivity – Suspension and Traction Control
Front Suspension
The three-point front suspension permits the axle to oscillate ±6°, softening impact loads on structures and components and providing a smooth ride, so the operator can travel at speed over rough terrain.
Rear Suspension
Features a walking beam geometry with Caterpillar designed rear suspension mounts which provide a reliable and stable ride for excellent load retention.
Traction Control
The traction control system is comprised of a wet clutched inter-axle differential and wet clutched cross-axle differentials. All differentials can be engaged and disengaged on-the-go for maximum versatility. When used together, the differentials provide 100 percent driveline locking.
Inter-Axle Differential Lock
Locks all three axles in unison and modifies torque distribution for excellent traction in poor underfoot conditions and on grades. It is operated by a switch located at the footrest.
Cross-Axle Differential Locks
Provides full driveline locking – all three axles and all six wheels – for maximum performance in the most adverse conditions. Acts in unison with the inter-axle differential lock when the footswitch is actuated and the dash-mounted switch is selected.
Exhaust Heat System
The body comes exhaust heat ready.
Steering System
Cat articulated trucks use a load-sensing steering system for smooth, precise control. It features a single, variable displacement pump. Two double-acting, cushioned steer cylinders allow the machine to articulate 45° to the left or right, permitting precise positioning in tight areas. Its compact Hand Metering Unit controls the cylinders for responsive steering and performance. An electronic secondary steering system is standard.
Performance and Productivity – Ejector
Ejector
The 730 Ejector is designed to disperse the load on-the-go for faster cycle times and lower spreading costs. The ejector body also offers clean load ejection and the capability to work in areas with restricted overhead clearance and soft underfoot conditions.
Versatility
The 730 Ejector is based on the standard 730 Articulated Truck and shares all its versatility. Similar in design to the well proven 740 Ejector model, the 730 Ejector can operate in the same conditions. The 730 Ejector offers a number of unique capabilities that stretches the operation envelope.
Spreading
The truck can eject the material and spread it out while moving, reducing the size of additional spreading and dozing equipment. This makes the 730 Ejector an ideal solution for road building and landfill applications. On-the-go ejecting results in faster cycle times and reduced power train loads.
Stability
Ejecting the load without raising the body increases stability, allowing load dispersal on inclines, side slopes, and in very soft underfoot conditions such as landfill sites. Generally, these conditions would be unacceptable with a conventional truck, but are ideal for the 730 Ejector.
Overhead Clearance
Because the body is not raised when ejecting the load, the truck can be utilized in areas with reduced overhead clearance such as when working around overhead lines, conveyors, hoppers and bridges. The ejector is also ideal for tunneling and underground operations.
Carry-Back
The design of the ejector is inherently self-cleaning and practically eliminates material sticking to the body, which increases productivity, improves fuel efficiency and lowers cost per ton.
Body
Reinforced body is made from thick high-yield, heat-treated Brinell hardened steel (Brinell 450 on the base and Brinell 400 on the sides) that provides exceptional durability. Ejector top rails are made from high-strength alloy steel. For optimum durability and wear life, the ejector body is designed to work in applications where the material consists of rocks smaller than 152 mm (6 in.) in diameter.
Blade
The ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractor-scrapers.
Cylinder
A three-stage, high-speed, double-acting cylinder is specifically designed for horizontal mounting and provides smooth load ejection. It is centrally supported and nitride-hardened to ensure a long service life.
Proven Technology
Much of the 730 Ejector design is carried over from the standard Cat 730 Articulated Truck.
