Left Pedal

Purpose Built Front Linkage

Cat coal 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) (834 only)

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 824H and 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 for your bottom line

Cat C15/C18 Engine with ACERT™ Technology

The Cat C15/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 coal 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 coal scoops offer a number of standard and optional features to enhance job site visibility.
Standardand optional features include articulated wiper/washer system with intermittent features,
optional rear vision camera, optional high intensity discharge lights, optional warning beacon and
optional turn signals.

5

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.

Optional Auto Reversing Fan

The fan reverses automatically at preset intervals toremove
debris from the inlet screen. It can also be reversed manually
from the cab.

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.

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.

6

Operator Comfort

Best-in-class working environment

Best-in-Class Working Environment

A comfortable operator is a productive operator, which is why Caterpillar has designed the 824H and
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, MP3, or satellite radio options.

STIC Steering System (834H only)

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 (834 only)

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.
