Availability
Cat Wheel Dozers are designed with durability built in, ensuring maximum availability through multiple life cycles. With optimized performance and simplified serviceability, our machines allow you to support your job site efficiently and safely while lowering owning and operating costs. Introduced in the mid-1960's, the 834 has been the industry leader for over 50 years. Focused on helping our customers succeed, we have continued to build upon each new series. The 834 continues our legacy of reliability, performance, safety, operator comfort, serviceability, and efficiency.
ENHANCED SAFETY
Equipped with standard safety features, improving visibility and providing a safer operating environmentLOWER MAINTENANCE COST
Make regular maintenance more convenient with scheduled engine and fuel filter change intervalsBETTER FUEL EFFICIENCY
Equipped with a combination of proven components and technologies, meeting expectations for excellent productivity, fuel efficiency, reliability, and service life
Unmatched Durability
- The full box-section rear frame resists torsional shock and twisting forces.
- Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame.
- Optimized axle mounting results in increased structural integrity.
- Achieve longer component life with increased size of upper hitch pin, frame plate, and bearing.
- Solid through-width push beams transfer and absorb stresses through a larger portion of the frame.
- Features fully enclosed hydraulic wet disc brakes for improved performance.
- Robust structures withstand the toughest conditions and multiple lifecycles to improve your bottom line.
- In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.
Optimum Efficiency
- The Cat C18 engine is designed for maximum fuel efficiency in the most demanding applications.
- Experience reliable efficiency with complete control over injection timing, duration, and pressure with Mechanically Actuated Electronic Unit Injection (MEUI™).
- Best-in-class Cat planetary powershift transmission features consistent, smooth shifting and efficiency through integrated electronic controls.
- Extended engine life and improved fuel efficiency with reduced rated speed.
- Impeller Clutch Torque Converter (ICTC) and Rimpull Control System (RCS) provide precise rimpull control.
- Load sensing hydraulic steering system enables precise machine control for easier loading.
- Lock-up torque converter with advanced control of lock-up speed.

- Dual lift cylinders provide hydraulic lift capacity matched to the demands of the application.
- Can be equipped with optional ground level accessible swing-out reversing fan for quick inspection and easy cleanout.
- Equipped with underhood ventilation system which creates a neutral pressure environment to prevent wood chip ingestion from hood openings while providing fresh air to the alternator, electronics, and turbo.
- Extended top guard for increased capacity for wood chip scoops.
- Higher ground pressure decreases risk of fires and maximizes use of storage space.
- Less damage to coal or wood chips due to rubber tires.
- High ground speed provides ability to manage multiple piles.
- Scoop design allows load and carry function for mixing.
- Lift and tip-out design makes stockpiling operations easy.
- Scoop tilt control is standard to maximize worksite efficiency.
