The Cat C18 engine is built and tested to meet your most demanding applications. Three C18 engine options are available in this machine: Tier 4 Final/Stage IV with aftertreatment, Tier 3 equivalent, or Tier 2 equivalent.

Fully integrated electronic engine controls works in concert with the entire machine to make your fuel go farther.
Use less fuel idling with Engine Idle Shutdown.
Maximized durability with Delayed Engine Shutdown.

Featuring all new Advanced Productivity Electronic Control Shifting (APECS) transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.

Enable your operators to maximize efficiency by varying machine rimpull while putting more horsepower to hydraulics.

Reduced tire wear
Enables full throttle shifts for faster cycle times
Provides smooth approach to the dump target for less spillage and faster cycle times.

Eliminates TC losses while lowering system heat
Improves travel speeds
Reduces cycle times in load and carry operations

New flow sharing implement and steering variable displacement load sensing piston pumps.
Hydraulic flow now on demand, for improved fuel efficiency.

Long Term Value and Durability

Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest 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.
Lower hitch pin, frame plate, and bearing size have been increased for longer life.

Push beams are through-width, not merely attached to side of frame.
In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.

Built to Perform

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 and less operator fatigue through the use of low effort integrated controls.

Integrated Cat® Technologies

The 834K electronic systems have been completely integrated to function as one machine. This integration creates a smart machine and more informed operator, maximizing the productivity of both. 834K Wheel Dozer Scoop

Cat Product Link allows remote monitoring of equipment to improve overall fleet management effectiveness. Events and diagnostic codes, as well as hours, fuel, idle time and other information are transmitted to a secure web based application, VisionLink™. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level and more. We have worked hard to help our customers and operators perform at their best through our Vital Information Management System (VIMS 3G).

Easy-to-view graphical information display features a large touch screen interface.
Intuitive operation and easy navigation with our enhanced user interface.
Decrease service time by keeping operators informed about machine system malfunction or operation.

Technology that Gets Work Done

Cat MineStar System is the industry's broadest suite of integrated mine operations and mobile equipment management technologies, configurable to suit your operation's needs. Its capability sets – Fleet, Terrain, Detect, Health and Command – contain a range of technologies that let you manage everything from fleet assignment and condition monitoring to remote and autonomous control. The 834K can take advantage of many of these advanced technologies, some of which are standard out of the factory. Fleet provides comprehensive, real-time machine tracking, assignment and productivity management, giving you a comprehensive overview of all operations from anywhere in the world. Terrain with your 834K enables high-precision management of loading operations through the use of guidance technology. It increases 834K productivity and provides you real-time feedback for improved efficiency.

Detect helps increase operator awareness, enhancing safety at your operation. It includes a range of capabilities designed to assist the operator with areas of limited visibility around fixed and mobile equipment.

Health delivers critical event-based machine condition and operating data for your entire fleet. It includes comprehensive equipment health and asset monitoring capabilities, with a wide range of diagnostic, analytic and reporting tools.

Safety First

We are constantly introducing features on our machines in an effort to enhance safety for the operator. 834K Wheel Dozer Scoop

Left and right hand stairs with 45 degree angle enhance safety for operators getting on and off the 834K.
Continuous walkway with non-skid surfaces are designed into the service areas.

Reduce Environmental Impact

Sustainability is designed and built into our 834K's features.

Engine Idle Shutdown and Auto Idle Kickdown can help you save fuel by avoiding unnecessary idling.
Reduce waste generation with our maintenance free batteries.
The 834K is built for multiple lives. 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.
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.

Achieve Greater Productivity

Cat wood chip and coal scoops have the unique capability of maximizing your production by both dozing and carrying a load with each pass. A purpose built hydraulic system is optimized for use with this work tool to maximize machine productivity and efficiency. Dual lift cylinders provide hydraulic lift capacity matched to the demands of the application. 834K Wheel Dozer Scoop

The fixed front axle and oscillating rear axle ensures four-wheel ground contact for optimum traction and stability. The front axle is rigidly mounted to the front loader frame, while the rear axle is allowed to oscillate. This configuration allows the operator's view of the scoop to remain constant as the rear axle oscillates enabling the operator to maintain a smooth and properly graded work area in any underfoot conditions.

Save on Fuel Costs

The 834K has several features to achieve greater fuel efficiency:

Positive Flow Control Hydraulics – Provides only the hydraulic flow required by the implement and steering systems for improved fuel efficiency and greater rimpull.
Engine – Advanced engine controls maximizes power and efficiency.
Engine Idle Shutdown – Automatic engine and electrical system shutdown conserves fuel.
Lock-up Torque Converter – Transfers more power to the ground and optimizes fuel efficiency in all applications.
Advanced Productivity Electronic Control Strategy (APECS) – All new APECS transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.

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

Machine Configuration – Select the correct work tool and tire type based on machine application. Ensure proper inflation pressures.
Idle – Set the parking brake to engage Engine Idle Management System.
