Efficiency and Productivity

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

Operators increase productivity with our responsive implements feature.

  • Operate comfortably through electronically controlled hydraulic cylinder stops
  • Handle easy-to-use soft detent controls

Integrated Cat® Technologies

Cat Connect makes smart use of technology and services to improve your job site efficiency. Using the data from technology-equipped machines, you'll get more information and insight into your equipment and operations than ever before. Cat Connect technologies offer improvements in these key areas: Equipment Management – increase uptime and reduce operating costs. Safety – enhance job site awareness to keep your people and equipment safe.

LINK Technologies

LINK technologies like Product Link™ wirelessly connect you to your equipment, giving you valuable insight into how your machine or fleet is performing. Track location, hours, fuel usage, idle time, and event codes through the online VisionLink® interface so you can make timely, fact-based decisions that can boost job site efficiency and productivity, and lower operating costs. VIMS™ data, like events, histograms, and historical trends, can be downloaded for analysis, giving you the information you need to proactively maintain fleet health and optimize performance and uptime.

DETECT Technologies

DETECT technologies like the rear-vision camera enhance awareness by expanding your view of the environment around working equipment so you can work at peak potential, with confidence.

Save on Fuel Costs

Save on Fuel Costs

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:

  • 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.

Safety First

We are constantly improving our products in an effort to provide a safe work environment for the operator and those who work on your job site.

Machine Access

  • Left and right hand stairs are angled to enhance safety for operators getting on and off the 824K.
  • Continuous pass-through with handrails and non-skid surfaces with toe kicks are designed into the service areas.
  • Maintain three points of contact at all times through ground level or platform accessible service areas.

Visibility

  • Optional rearview camera with in-cab monitor increases operator awareness around the machine.
  • Standard cab mounted LED warning strobes

Operator Environment

  • Reduced vibrations to the operator with isolated cab mounts and seat mounted implement and steering controls.
  • Low interior sound levels
  • Pressurized cab with filtered air
  • Standard 76 mm (3 in) seat belts on the operator seat

Purpose-Built Cat Attachments

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.

Long Term Value and Durability

Robust Structures

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

  • Full box-section rear frame resists torsional shock and twisting forces
  • 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.
