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.
- 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.
- 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.
- 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.
- 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.

Tires
| Note (2) |
Caterpillar recommends the customer evaluate all job conditions and consult the tire manufacturer for proper tire selection. |
| Note (1) |
Productive capabilities of the 773G truck are such that, under certain job conditions, TKPH (TMPH) capabilities of standard or optional tires could be exceeded and, therefore, limit production. |

ROPS
| FOPS Standards |
Falling Object Protective Structure (FOPS) meets ISO 3449:2005 Level II FOPS criteria. |
| ROPS Standards |
Rollover Protective Structure (ROPS) for cab offered by Caterpillar meets ISO 3471:2008 ROPS criteria. |
Sound
| Sound Standards (3) |
Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in a noisy environment. |
| Sound Standards (2) |
The exterior sound pressure level for the standard machine measured at a distance of 15 m (49 ft) according to the test procedures specified in SAE J88:2008, mid‑gear moving operation is 86 dB(A). |
| Sound Standards (1) |
The operator Equivalent Sound Pressure Level (Leq) is 76 dB(A) when SAE J1166 FEB2008 is used to measure the value for an enclosed cab. This is a work cycle sound exposure level. The cab was properly installed and maintained. The test was conducted with the cab doors and the cab windows closed. |
