Overview

Enhanced performance

Caterpillar is pleased to introduce to you the 773 Off-Highway Truck. You may be asking how, after 40 years of building trucks, Caterpillar has improved this product’s ability to support your business.
The 773 Off-Highway Truck has been designed and manufactured using the latest quality control technologies – virtual and hands on. This product has over 30,000 hours of proven performance in the hands of customers prior to production, all of which ensures the truck delivered to your yard is ready to work, reliably and dependably.
In addition to quality, Cat 773 trucks will lower your costs with seven different ways to help you conserve fuel. We offer you two customizable fuel economy modes that will let you choose your level of savings. With Cat 773 trucks in your haul fleet, you can be more productive, spend less time on maintenance, and support the environment with new levels of eco performance. Your crew will appreciate all the new comfort and conveniences in our updated cab. Simply put, the Cat 773 trucks can and will make a positive difference to both your business and people – all day, every day.

Benefits

Up To 9% Less Fuel Consumption

Utilizing Adaptive Economy Mode helps save on fuel consumption while maintaining productivity.

Enhanced Operator Comfort

New left side seat placement allows for an easier operation and new levels of comfort all throughout the work day

Expanded Performance

Get the job done faster and more efficiently with increased travel speeds and improved traction control.

Features At A Glance

ACHIEVE GREATER PRODUCTIVITY

Haul your materials faster with an accelerated travel speed.
Put more power to the ground with increased torque.
Enjoy greater productivity while using a more responsive Traction
Control System (TCS).
Reduce tire wear with maximum by engaging TCS early in the slip.
Strong, predictable performance helps operators achieve the lowest cost per ton.

BOOST FUEL EFFICIENCY

Up to 13% less fuel consumption.
Advanced Productivity Electronic Control System (APECS) allows the engine and transmission to communicate on a high level. This communication allows the machine to better utilize the power and torque the engine is producing.
Automatically optimize fuel consumption with the feature—Adaptive Economy mode reduces fuel use without affecting productivity and can be engaged with a single button.
Gain improvements in fuel efficiency with auto-neutral idle.
Haul your 773 truck at a more fuel-efficient engine speed and gear selection with speed limiting.
Conserve fuel with integrated Engine Idle Shutdown by the engine automatically initiating when the truck is in park and idle for a preset amount of time.

DESIGNED FOR SAFETY

Improvements in accessibility with safe, ground-level access tofuel fill and daily maintenance points.
Ensure three points of contact when entering and exiting the machine with strategically placed walkways and grab rails.
Superior brake performance meets the latest brake standards—
ISO 3450:2011.
The ground-level engine shut-off switch stops all fuel to the engine when activated and shuts down the machine safely.
Sturdy 4-point mounted cabin meets rollover protective structure/
falling objects protective structure (ROPS/FOPS) standard.
4-point seat belt provides enhanced safety to the operator.
Seat belt indicator implements both visual and audible alerts to the
operator when seat belt is not fastened.
Lockout features help the service technician to perform
maintenance work on the machine with safe mode.
Secondary steering activates automatically in case of primary
system failure.
Overload speed limiter works with truck payload system to reduce
machine speed automatically when the truck is overloaded.

WORK IN COMFORT

Completely redesigned cab for a whole new standard in visibility, comfort, and productivity.
The new operator seat placement provides easier operation and comfort to the operator.
Improvements in enlarged views of the work area and its surroundings.
Access connectivity and decrease clutter with more storage areas in the newly designed cab.
Automatic cab temperature controls.
Cat next-generation deluxe seat for better operator comfort.

TECHNOLOGY THAT GETS WORK DONE

Integrated systems give you the ability to make timely, fact-based
decisions to maximize efficiency, improve productivity, and lower
costs.
Gain valuable insight into how your machine is performing by
continuously monitoring and collecting vital machine dta via the advisor display with the software Bital Information Management System (VIMS™). Applicable to both U.S. EPA Tier 4 Final/EU Stage V and U.S. EPA Tier 2 equivalent.
Truck Production Management System (TPMS) provides accurate weighing of the materials, stores 2,400 payload cycles, and reportson, haul cycle times, and distances with date and time stamps.
External payload indicator lights alert the loader when to stop, reducing the risk of machine overloading.
Product Link™ system connects to each machine wirelessly,
allowing you to monitor location, hours, fuel use, productivity, idle
time, and diagnostic codes.
VisionLink®
wirelessly connects you to your equipment, giving
you access to essential information you need to know to run your business.
The Cat 773 is MineStar™ ready and includes Cat Product Link
Elite and VIMS to help optimize equipment management, remote
monitoring capabilities, machine availability, and component life while reducing both repair costs and the risk of catastrophic
failure.
Tons kilometers per hour/tons miles per hour (TKPH/TMPH) tire
management system works with TPMS for improved tire life.

REDUCED MAINTENANCE COST AND OTHER COSTS

Grouped service points.
Control particulate matter with two engine-mounted diesel oxidation catalyst canisters. (Tier 4)
NRS technology replaces a portion of intake air with exhaust gas to control combustion temperatures and NOx production. (Tier 4)
Parts commonality with other Cat equipment.
Resolve problems before failure occurs with VIMS notifications.
Autostall enables quick operating temperatures for best performance life.
Prevents hot shutdowns that can reduce component life with the use of delayed engine shutdown.
Hydraulic oil filter life is extended to 1,000 hours under normal operating conditions.

APPLICATION VERSATILITY

Get the right body option—Dual Slope, Flat Floor, or Quarry—for your material and jobsite needs.
For haul profiles including steep slopes, an optional Dual Slope body is available—offering excellent material retention.
The flat floor body is perfect for metering material, especially when
feeding the crusher.
Optimize your body life by selecting a liner package best suited
for your application. We offer steel liners that work for most applications as well as rubber liners for extreme applications.
