Benefits & Features
Engine
The Cat® C18 engine with ACERT™ Technology is U.S. EPA Tier 3 and EU Stage III compliant. It features increased horsepower and efficient fuel management for quick response, high productivity and exceptional service life. A sculptured cylinder block provides greater strength and is lighter weight.
Linkage Regen Valve
The regen valve creates a closed loop system to ensure optimal flow to the blade lift cylinder during the blade cycle. The improved flow reduces the head-end void of the lift cylinder after lowering, improving blade response and controllability.
Impeller Clutch Torque Converter (ICTC) Left Pedal Control
The ICTC allows the operator to modulate rimpull to the wheels and slow the machine down without reducing engine speed. This allows the machine to maintain full hydraulic power for blade and steering control which gives the 834H a hydrostatic feel while keeping the benefits of the world’s most efficient and powerful drive train and powershift transmission with lock-up control system.
Automatic Blade Positioning
This patented system mimics manual operations by automatically lowering the blade when the machine is shifted forward and raising it in reverse. The set points to where the blade raises/lowers can be easily adjusted from the operator’s seat.
Speed and Versatility
The speed and mobility of the 834H wheel dozer gives it the versatility needed to perform a variety of jobs on your job site:
If an operator is not actively operating the 834H for a period of time, the AIK system will temporarily reduce the engine speed to save fuel. After an automated engine speed reduction, the system will automatically resume the engine speed to the previous setting when the operator engages the implement control pod or the F-N-R switch on the STIC™ Steer.
Engine Idle Shutdown
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.
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 economy.
Combining the use of robotic welding and castings in critical high stress areas, more than 90 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.
Cat Planetary, Power Shift Transmission
Electronic shifting provides smooth, consistent shifts. Large diameter clutches coupled with four planetary gear trains provides added durability for extended, trouble free life.
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 increased performance, serviceability and durability.
Final Drives
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.
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.
Optional Engine Brake
An optional engine brake offers additional engine retarding, reducing the load on the service brakes and extending service brake life.
