Is based on one of the most successful engines offered by Caterpillar, the 3406E. The 3456 is Tier 2 compliant and features increased horsepower and efficient fuel management for quick response, high productivity and exceptional service life. A new, sculptured cylinder block provides greater strength and is lighter weight.
Controls the fuel injector solenoids to start and stop fuel injection. This system provides automatic altitude compensation, air filter restriction indication and will not allow the engine to fire until it has oil pressure, acting as a cold start protection and a form of pre-lube.
Isolates the radiator and fan from the engine compartment for more efficient cooling and allows for a sloped hood for increased viewing.
Improves cooling capabilities by using a parallel flow system with 10 cores. Serviceability is improved with AMOCS as there is no top tank to remove.
Features preimeter-mounted, large diameter clutch packs that control inertia for smooth shifting and increased component life.
Feature optional axle oil coolers, permanently lubed universal joints and stronger axle components in both the differentials and final drives for increased performance, serviceability and durability. Conventional differential is standard.
Can be removed independent of the wheels and planetaries for quick and easy serviceability.
Features two circuits that circulate oil from the differentials through an oil-to-air cooler and a filter back to the brakes. This system provides increased oil life and improves component performance and durability. The system automatically turns on and off at a preset oil temperature.
Are fully modulated and the front and rear service brake circuits are isolated so one circuit can operate if pressure drops in the other circuit.
Are four wheel, hydraulic, oil dipped multiple disc brakes that are adjustment-free, completely enclosed and allow modulated engagement without slack adjusters.
Is spring-applied, oil-released and dry disc. It is mounted on the transmission transfer gear output shaft. Manual override is possible to allow movement of the machine.
Increases hydraulic efficiency and enhances operator comfort through low-effort fingertip controls. XT-3 and XT-5 hose combine with reliable components to help reduce the risk of leaks and blowing lines.
A floor mounted single-lever, fingertip control for lift/lower/tilt/tip sends electronic signals to a main hydraulic valve positioned outside the cab. This eliminates sound, heat and control effort associated with in-cab hydraulic valve systems.
With the STIC control system, integrates steering and transmission into a single controller. The steering system utilizes a variable displacement pump for maximum machine performance by directing power through the steering system only when needed.
Continually monitors various machine systems through three instrument clusters and provides a three-level warning system to alert the operator of immediate or pending problems. EMS III shares information with the engine, hydraulic and transmission controls that can be used during servicing to simplify service and troubleshooting. EMS III allows for new software to be uploaded in the cab.
Is a speed controlled, hydraulic fan that provides maximum cooling efficiency by directing the appropriate amount of power through the fan system based on coolant temperature.
The 834G has two case drain filters that protect the steering and fan pumps from contamination with easy access for service.

The 834G has two case drain filters that protect the steering and fan pumps from contamination with easy access for service.
Combine the use of robotic welding on up to 90 percent of the 834G while castings in several areas to increase strength by helping to spread the loads and reduce the number of parts. This provides highly consistent welds with deep plate penetration and excellent plate fusion. The benefit is increased durability and fatigue strength. The computer controlled machining ensures the alignments of pin bore, axle pad, cab mount and transmission/engine components.
Is designed to resist twisting and torsional forces and to provide a solid foundation for axles, engine and transmission.
Provides maximum structural strength during dozing applications for improved stability.
Is large and improves load distribution by reducing loads to the hitch bearings. The large center hitch design improves hydraulic line routing and makes service access easier.
Pivot on double-tapered roller bearings. Box-style sections in the hitch pins and cross member assembly improve strength of the frame structure.
Use a rubber, mushroomed, cup-shaped design to reduce noise and vibration.
Straight side rail design improves torsional strength, shock load absorption and frame alignment. It is specifically designed with fewer parts to improve quality and reliability.
With over 3.18 m3 (112 ft3) of volume incorporates innovations for operator comfort, maneuverability and productivity. Features include outstanding viewing area, improved cab ventilation, interior sound levels below 77 dB(A), standard coat hook, cup holder, storage bin, intermittent wet-arm wipers, room for a large lunch cooler and radio-readiness.
Combines gear selection and steering into one control lever that requires less effort and provides smooth shifting. Side-to-side motions for steering, finger operated direction control and thumb operated buttons for gear selection combine to provide a fluid motion that reduces effort and allows the operator to work the machine for long periods of time with little or no fatigue.
Operates the Impeller Clutch Torque Converter. Within the first one and a half inches of pedal travel, rimpull can be controlled from 100 percent to 20 percent. Fully depressing the pedal applies the brake. The right pedal allows standard braking.
With air suspension and retractable seat belt is designed for increased comfort and support. Seat cushions reduce pressure on the lower back and thighs while allowing increased arm and leg movement.
Are adjustable fore and aft, with a height-adjustable armrest so operators of any size can find a comfortable position. Single lever control allows operator to control blade functions: lift/lower, tip and tilt.
Allows operators to select tilt or tip control for dozing.
Allows the operator to pre-set the engine speed for a variety of applications, resulting in faster cycle times and increased productivity.
Has four factory preset rimpull settings (low, medium, high and maximum) that can be modified by the dealer for operator preference or to better match ground conditions.
Allows the operator to set the maximum gear into which the transmission will be allowed to shift. This feature allows additional comfort and focus on the job. The switch also offers a manual position for operator controlled shifting.
Activates lock-up clutch for direct drive efficiency.
Are within easy reach to maintain a clear field of vision.
Is improved with bonded front windshield that eliminate distracting metal frames for excellent bucket and work site visibility. An internal ROPS improves peripheral viewing by eliminating the large structure outside the cab.
Disables hydraulic controls.
Is designed for production dozing in stockpiled material and general earthmoving.
Is designed for moving large loads over long distances in mining applications.
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.
For the straight blade and universal blade consist of the blade, push arms, hydraulic lift, tip and tilt cylinders, trunnion mounting and hydraulic line guards.
In addition to the servicing features built into the engine, the 834G includes:
Make detailed comparisons of the machines under consideration before purchase. Cat dealers can estimate component life, preventative maintenance cost and the true cost of lost production.
Look past initial price. Consider the financing options available as well as the day-to-day operating costs. Look at dealer services that can be included in the cost of the machine to yield lower equipment owning and operating costs over the long run.
Cat dealers offer a variety of product support agreements and work with you to develop a plan that best meets specific needs. These plans can cover the entire machine, including work tools, to help protect your investment.
You will find nearly all parts at our dealer parts counter. Cat dealers use a world-wide computer network to find in-stock parts to minimize machine down time. Save money with genuine Cat Remanufcatured parts. You receive the same warranty and reliability as new products at cost savings of 40 to 70 percent.
Improving operating techniques can boost profits. Your Cat dealer has training videotapes, literature and other ideas to help increase productivity.
