Efficiency and Productivity

Delivering the efficiency and productivity you demand through integrated machine systems.

Efficiency with Autoshift

The Autoshift mode, when active, allows the machine to automatically upshift or downshift based on machine speed, optimizing performance and thus saving fuel. This feature can be easily enabled or disabled on the soft keypad.

Decelerator Pedal

The left pedal acts as a brake, transmission neutralizer and an engine decelerator to override the engine speed selected by the throttle lock. This enables the operator to slow down when the throttle lock is engaged and to return to throttle lock without pressing a resume or set button again. This aids in maneuvering around trucks, tractors or any other obstacle.

Steering and Transmission Integrated Control System (STIC™)

Experience maximum responsiveness and control with STIC that combines directional selection, gear selection and steering into a single lever.

• Simple side-to-side motion turns machine right or left, minimizing operator movements
• Easy to operate finger controlled gear selection
• Smoother, faster cycles help reduce operator fatigue through the use of low effort integrated controls

Steering System

Confident machine operation starts with precise machine control enabled by the 824K’s load sensing hydraulic steering system.

• Increase efficiency with our variable displacement piston pumps
• Achieve precise positioning for easy loading in tight areas with 43 degrees each way of steering articulation
• Enhance operator comfort with integrated steering and transmission control functions

Electro Hydraulic Controls

Structures

Purpose-built from the ground up for the toughest conditions.

Robust Structures

Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest loading conditions.

• Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame
• Axle mounting has been optimized for increased structural integrity

Push Beam and Push Arm Dozer Arrangement

To ensure long life and reliability, solid one piece push beams are through-width, not merely attached to the side of the frame. In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.

• Reduce waste to the environment with our maintenance free batteries.
• Built for multiple lives, the Cat 824 is one of the most rebuilt products to achieve the second and third life to get the most value from your investment. To assist with maximizing machine life, Caterpillar provides a number of sustainable options such as our Reman and Certified Rebuild programs. In these programs, reused or remanufactured components can deliver cost savings of 40 to 70 percent, which lowers operating cost while benefiting the environment.
• Caterpillar offers retrofit packages to bring new features to older machines, maximizing your resource. And, when you go through the Cat Certified Rebuild program, these retrofit kits are part of the rebuild process.

Blades

Cat blades to match your customers dozing requirements.

Cat Blades

Cat blades are resilient, durable and designed with excellent dozing and rolling characteristics.

• Capacities and widths are set to achieve increased productivity.
• Spreading design allows for spreading of cover material, as well as dozing of heavier loads.

Straight Blade

The straight blade (5.0 m3/6.6 yd3) is designed for production dozing in stockpile material and general earthmoving.

Universal Blade

The universal blade (7.7 m3/10.0 yd3) is designed to move large loads over long distances in mining applications.

Semi-Universal Blade

The characteristics of the straight and universal blades are combined into the semi-universal blade (7.7 m3/10.0 yd3). It provides increased capacity with the addition of short wings which include only the dozer end bits without sacrificing spreading characteristics of straight blades.

Coal Blade

The coal blade (16.2 m3/21.1 yd3) is designed for precise and productive dozing while helping to retain load control with increased capacity for lighter materials. Wing angles help retain the load while dozing.

Assemblies

The blades are combined with bulldozer assemblies which consist of the push arms, hydraulic lift, tip and tilt cylinders, trunnion mounting, stabilizer and hydraulic line guards.

Extended Wear Bulldozer Arrangement

The Extended Wear bulldozer arrangement is designed for moving large loads over long distances in harsh conditions. It consists of an 8.1 m3/10.7 yd3 U-blade with Abrasion Resistant Material (ARM) on the front and sides, cutting edges, push arm and integrated cylinder guards, and a heavy-duty stabilizer.

Other Available Options

See your Cat dealer for other blade options.

Operating Costs

Save time and money by working smart.

Data from customer machines show Cat Wheel Dozers are among the most fuel efficient machines in the industry. Several features contribute to this excellent fuel efficiency:

• ACERT Engine – Advanced engine controls maximizes power and efficiency.
• Engine Idle Shutdown – Automatic engine and electrical system shutdown conserves fuel.
• Lockup Torque Converter – Transfers more power to the ground and optimizes fuel efficiency in all applications.
• Single Clutch Speed Shifting (SCSS) – All new SCSS transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.
• Fuel Tank Capacity minimum of 12 hours operation depending on the application.

Machine configuration, operator technique, and job site layout can impact fuel consumption.

• Machine Configuration – Select the correct blade configuration based on your individual application.
