PRODUCTIVITY,RELIABILITY & FUEL EFFICIENCY
Productivity is critical to your bottom line. Cat 834H offers features and systems that help to improve performance and lower your cost-per-ton.
The Cat® C18 engine with ACERT™ Technology features increased horsepower and efficient fuel management for quick response, high productivity and enhanced service life.
PURPOSE BUILT FRONT LINKAGE
Cat 834H maximizes your mining 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.The linkage regen valve creates a closed loop system to ensure optimal flow to the blade lift cylinder during the blade cycle.
AUTO IDLE KICKDOWN (AIK)
When the operator is not actively operating the machine for some period of time, the AIK system temporarily reduces the engine speed to save fuel. After an automated engine speed reduction, the system automatically resumes the engine speed to the previous setting when the operator engages the implement control pod of the F-N-R switch to the STIC™ Steer.
IMPELLER CLUTCH TORQUE CONVERTER (ICTC) LEFT PEDAL CONTROL
The ICTC has a throttle lock to allow the operator to modulate rimpull to the wheels and slow the machine down without reducing engine speed. This enables the machine to keep full hydraulic power for blade and steering control which gives the 834H a hydrostatic feel.
OSCILLATING REAR AXLE
The fixed front, 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.
LOAD SENSE STEERING
The steering system utilizes a variable displacement pump for maximum performance by directing power through the steering system only when needed. This improves efficiency and reduces heat build up.
SPEED & VERSATILITY
The speed and mobility of the 834H wheel dozer makes it ideal to perform a variety of jobs on your job site:
- Haul road maintenance
- Dozing truck dumps
- Loading area maintenance
- Blasting maintenance
VARIABLE SHIFT CONTROL (VSC)
VSC matches transmission shifting patterns to machine application requirements, by shifting at lower engine rpms. This both improves shift quality and fuel efficiency in certain applications.
Lock-up Clutch Torque Converter
The lock-up clutch torque converter provides direct drive efficiency, translating into improved fuel econom
CAT PLANETARY, POWER SHIFT TRANSMISSION
Electronic shifting provides smooth, consistent shifts. Large diameter clutches coupled with four planet gear trains provide added durability for extended, trouble free life.
Combining the use of robotic welding and castings in critical high stress areas, more than 80 percent of the machine structure is robotically welded to provide highly consistent welds and increased strength. Castings are also used in several areas to increase strength by helping spread the loads and reduce the number of parts.
AXLE-SHAFT, OIL DISC BRAKES
These brakes are adjustment free, fully hydraulic and completely sealed. Disc face grooves provide cooling even when brakes are applied for a longer component life.
- Location of brakes allow for improved serviceability. The axle shaft brake design allows for brake service while leaving the final drive intact.
- Axle-shaft brakes require less force by operating on the low torque side of the axle. Combined with improved axle oil circulation for increased cooling, the oil-enclosed, multiple disc brake design improves durability.
HEAVY DUTY AXLES
Optional axle oil coolers, permanently lubed universal joints and stronger axle components in both the differential and final drives are offered for better performance, serviceability and durability.
The final drives feature planetary reduction at each wheel. Torque is developed at the wheel which provides less stress at the axle shafts extending axle life and reducing owning and operating costs. Proprietary gear cutting and heat treating methods are used in the manufacturing to provide best in class reliability and durability.
The 834H has a number of features that minimize operator fatigue, resulting in a safe, productive work . The world class cab incorporates features for operator comfort and ergonomics, visibility and ease of operation.An updated Implement Pod is fully adjustable and designed for low-effort comfort. Switches and controls are located within easy reach of the operator.Interior noise levels are reduced to a quiet 73 dB(A).
Cat Monitoring System (EMS-III) provides information on machine’s major components. This includes gauge displays for the fuel tank level; temperature gauges for the engine coolant, torque converter and hydraulic oil; tachometer analog gauge with digital readout for gear selection and ground speed and a monitoring system.
The STIC steer controller uses a single lever for steering and transmission control. Left-hand operations enable the operator to shift and change directions without letting go of the steering controls.
This new feature will automatically shutdown the engine after the machine has been in a safe idling state for an extended amount of time. The operator in the cab will be audibly and visually warned before the shutdown occurs.
