Productivity

Improving your bottom line

Purpose Built Front Linkage

Cat wood chip 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.

Auto Idle Kickdown (AIK)

If an operator is not actively operating the machine 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 of the F-N-R switch to the STIC™ Steer.

Impeller Clutch Torque Converter (ICTC) Left Pedal Control

The ICTC works with throttle lock to allow 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.

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 machine performance by directing power through the steering system only when needed. This improves efficiency and reduces heat build up.

Reliability

Maximizing uptime, long life - it’s what you expect from your bottom line

Cat C18 engine with ACERT™ technology

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.

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.

Structures

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.

Safety

Built to protect you

Entry and Exit

Getting on and off the machine is one of the leading causes of injury on a job site. Cat wood chip scoops have a number of features to ensure your operator gets safely on and off the machine. They include primary and secondary stairwell exits, punch stamped tread plates, ground level nighttime stairwell light switch, full perimeter railings on upper platforms, side platform emergency egress and toe kicks and optional roading fenders.

Rearview Camera

With the new optional rearview camera, visibility is greatly enhanced. The camera is located in a pocket on the grill to protect it from damage and the elements. The camera can be set to activate only when the transmission is in reverse to help eliminate distractions in the cab, especially when in dark environments.

Visibility

Cat wood chip scoops offer a number of standard and optional features to enhance job site visibility. Standard and optional features include long life LED lights, articulated wiper/washer system with intermittent features, front walk around platform for easy windshield cleaning access, optional rear vision camera, optional high intensity discharge lights, optional warning beacon and optional turn signals.

Serviceability

Easy to maintain. Easy to service.

Optional Swing Out Radiator Fan

The optional swing out radiator fan provides for easy access to the radiator cores for easy cleaning and inspection.

Auto Reversing, Hydraulically Driven Demand Fan

The demand fan automatically adjusts fan speed for optimal cooling, resulting in reduced power draw on the engine, better fuel efficiency and more power for hydraulics and rimpull. The fan reverses automatically at preset intervals to remove debris from the inlet screen. It can also be reversed manually from the cab.

Component Access

Swing out doors on both sides of the engine compartment provide easy access to the engine oil dipstick and filler spout, S·O·SSM ports, fuel filters air conditioner compressor, engine oil filters, alternators, starting receptacle, air filter service indicator, cooler fill and ether starting aid. There are also ground level viewable sight gauges on all major systems and centralized remote pressure taps.

Shutdown and Lockout Features

An electrical disconnect switch and hydraulic lockout switch allow service technicians to perform maintenance while the machine stays static. Other shutdown or lockout devices include ground level engine shutdown and ground level steering hitch lock lever.

Operator Comfort

Best-in-class working environment

A comfortable operator is a productive operator, which is why Caterpillar has designed the 834H with a best-in-class working environment for this size scoop. 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). Options include heated seat for cold weather operations and Bluetooth, MPS, or satellite radio options.

STIC Steering 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.

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.
