Cat® C9 Diesel Engine
The Cat® C9 is an 8.8 liter (537 in³) displacement, six-cylinder, in-line configured engine with hydraulically actuated electronic fuel injection or HEUI™. The 196 kW (263 hp) rated net power engine meet the latest worldwide emissions standards (10% more than C-series). It uses ACERT™ Technology that provides advanced electronic control, precision fuel delivery and refined air management. This proven technology with thousands of hours in field operations, results in outstanding performances with a constant net horsepower.
Electronic Control ADEM™ A4
The Advanced Diesel Engine Management System continuously monitors important engine conditions and functions. ADEM™ A4 manages fuel delivery to get the best performance per liter of fuel. The controller uses sensors in fuel, air intake, exhaust and cooling systems and provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. ADEM A4 is the electronic brain of the machine that ensures optimal performance.
This system offers numerous benefits, including better cooling performance, reduced plugging, enhanced cold weather operation and improved fuel economy. To reduce fan noise, the cooling fan is driven from a friction disc clutch, which is electrically controlled.
The electronically controlled Hystat drive provides quick response for shorter cycles times and increased productivity. The Hystat drive also offers independent power and efficient control of each track, with fast acceleration and infinitely variable speeds. The operator can command smooth machine turns and counter-rotation.
The 973D features a load sensing hydraulic system that automatically adjusts to operating conditions to provide only the hydraulic flow required by the implement for improved fuel efficiency. This modular hydraulic system delivers precise control with low effort operation and allows simultaneous lift, tilt and travel.
Position Sensing Cylinder
Position Sensing Cylinders (PSCs) are designed to allow for “smart” hydraulic systems. PSCs improve productivity by enhancing operator control. Operator can set lift and tilt kickouts at any position according to the applications without leaving the cab. Electronics within the cylinder allow the hydraulic system to be linked into the machine’s electronics. This link enables the system to track the cylinder stroke, reducing operator effort, and increasing productivity. PSCs allows the machine to use advanced automatic features for smooth start and stop cylinder motion, reducing vibration in the cab.
The standard programmable automatic kickouts provide flexibility and productivity for precise load and dump target heights. Tilt and lift kickouts are set by positioning the bucket or work tool and setting a rocker switch in the cab.
Designed for Comfort
The D-Series cab is designed for operator comfort, convenience and to provide an excellent view to the bucket, tracks and ripper. In particular, the air-suspension seat is ergonomically designed, fully adjustable and vibration-isolated for maximum operator comfort and control. The seat-mounted electro-hydraulic controls provide less vibration for the operator, and they allow combined seat and controls adjustment. The workstation is spacious, quiet and comfortable, assuring high productivity all day long.
Electro-Hydraulic Implements Controls
The new electro hydraulic implement controls provide the operator with responsive, smooth and precise control of bucket and lift arms. A choice of joystick or two-lever control for bucket lift and dump is available as an option.
Hydrostatic Drive System Controls
This accurate control system allows quick machine travel speed, on-the-go directional changes and counter rotation. A choice of V-lever and joystick for speed and steering control is available through the price list.
The 973D comes standard with Cat Messenger, providing real-time machine performance and diagnostic data. Messenger uses a LCD screen to display graphic and text information on machine health, including operating hours, total fuel, fuel consumption rate and total distance. Through Messenger, operator can create his own profile and set Hystat, implement and steering reactions.
The undercarriage on the 973D features an oscillating track roller frame design which decreases ground shock to the machine, increases machine stability, and provides a smoother, more comfortable ride for the operator.
Track link design consists of specially heat-treated steel forgings with different degrees of hardness induced into the steel. This feature increases links’ life and lowers owning and operating costs. A two-piece master link helps servicing the track chain and reduces down time. All those features help increase loader productivity throughout its life.
Maximize Your Productivity
The standard double grouser shoes are designed for good traction, easy turns and bending. However the 973D is available with several shoes options to best match to the job conditions. Any details count, and a single track shoe can make the difference.
Mainframe and Loader Tower
The D-series Main Frame and Loader Tower are made of single, slab rails with reinforced crossing, with castings and forgings incorporated at points of high stress. This particular design distributes those stresses over wider areas for longer structural life.
Durability Over Years
Structures are designed to provide durability and extended service life to support multiple rebuilds.
Wide Range of Buckets
The combination of the right bucket with the right machine will provide the best possible performance in your particular application. The General Purpose (GP) bucket is designed for excellent loadability and long life in applications such as hard bank excavating, stripping, and stockpile loading. The Multipurpose (MP) bucket is designed for a broad range of applications, such as loading, stripping, clearing, bulldozing, picking up debris, and fine grading. The bucket clamps hydraulically to grip or handle other tough-to-grasp materials. For special applications, Caterpillar also provides buckets with special features such as Landfill GP/MP Buckets, or Slag Bucket designed to work in the extreme conditions of a steel mill, including moving slag and skulls.
The multi shank parallelogram ripper adds extra versatility and force to expand the machine’s range of applications. The ripper beam has three pockets for holding ripper shanks, and its design allows the machine to rip frozen ground, asphalt and even hard soils or rock. Longer shanks deliver more work per pass making the machine more productive.
K Series™ Tooth System
The K Series tooth system matches customer expectations for tip retention, easy change-outs and long-term sharpness. The K Series tooth system also features a lower-profile shape that maintains better sharpness as it wears. This means better penetration, improved productivity and less strain on the machine.
General Construction Package
973D is a one-machine workforce that can tackle any task in any jobsite, from general construction to industrial or quarries.
Waste Handling Standard and Extreme Service Packages
On both packages, substantial guarding, debris barriers, cooling system enhancements and precleaners are added to enhance the life and performance of the 973D. The WH standard package should be selected for jobs in landfills, transfer stations or material recovery facilities. The WH ES will be a better fit for transfer stations, demolition sites, severe applications, or when maximum protection is desired.
Steel Mill Package
The steel mill package protects the 973D and its operator against extreme conditions to allow the machine to handle hot slag in steel mill operations. This special package features additional guarding for critical components, sealed undercarriage, heat shields for fuel tank, power train and hydraulics, silicone seals and heat resistant windshield, remote parking brake release and fire-resistant fluids. The Steel Mill Arrangement provides the best protection available for this extremely difficult application.
Wide Gauge Package
The 973D Wide Gauge is designed to work in soft underfoot conditions. The track gauge is widened and wider track shoes installed. A wider bucket also increases productivity, especially in grading and backfilling.
