Body Options

           

Our truck bodies are engineered to compliment the chassis and built to haul your material for years of trouble-free performance. In fact, Cat truck bodies are designed to let the truck perform at peak efficiency by correctly centering and distributing the load. Outfitting your truck body with a steel or rubber liner may be advisable based on material type and application. If you have questions about body selection or applying liners, your Cat dealer has the tools and knowledge to help you with this decision process.

The Rubber Liner

This important factory-installed option will prolong body life in hard rock applications.

  • Available for the dual slope and flat floor bodies

  • It will reduce shock loading for both the operator and truck

  • It absorbs noise, reducing both spectator and operator sound levels

  • The rubber liner is not a good option for wet, sticky material

  • The rubber liner should not be used with our body heat option


Side Boards

In the event that your material is light weight, we offer factory-installed 150 mm (6 in) sideboards to help you achieve rated capacities. You can use our “Body Selection Guide” as a reference for selecting the correct body type and liner package. Cat dealers can order this document using reference number AEXQ0673.

Dual Slope Body

If your haul profile includes steep slopes, the dual slope body offers excellent material retention.

  • The dual slope has a SAE 2:1 heaped capacity of 35.20 m3 (46 yd3) with a steel liner configuration

  • 400 BNH steel on interior surfaces offers excellent wear characteristics

  • Material is carried low and centered for stability

  • A single 16 mm (0.62 in) steel liner option is available for this body

  • A single rubber liner is available for this body


Flat Floor Body

If you're feeding a crusher, the flat floor body is an excellent choice for metering material.

  • The flat floor body also offers excellent material retention and stability

  • 400 BNH steel is used on internal surfaces for wear protection

  • A single steel liner option is available

  • A rubber liner is also available for this body




Sustainability

           

As you work for a more sustainable business model, the Cat® 773G can contribute in more ways than one.

Fuel and Emissions


  • There are multiple fuel saving strategies on the 773G, two are economy modes that are adjustable to meet your unique production needs

  • For the U.S., Tier 4 Final emission controls are conveniently low maintenance and are transparent to the operation of the truck


Sound


  • Operator noise is reduced by 50% using sound suppression technology in the cab

  • A rubber liner option for truck bodies reduces noise levels for both the operator and spectators


Component Life

Long Term Value and Durability

           

At Caterpillar, we know that our truck is critical to your business, that's why we use industry leading technology to ensure maximum machine availability and reliability.

Structural Strength

The backbone of the 773G is its frame. Our frames are designed for off-road integrity and more than one life cycle. The 773G, with its new power and performance increases, has updated final drive gears and a new rear axle housing to support this new level of work.

  • Caterpillar strategically applies castings with box section construction to manage off-road stresses

  • A new front frame design increases the approach angle on ramps and grades

  • New heavy duty gears compliment the updates in power and torque

  • A new robust rear axle housing also supports the truck's performance


Suspension


  • Front struts use our proven king pin design for effective absorption of haul road shocks

  • Rear suspension cylinders have been inverted to minimize contamination


Planetary Powershift Transmission with APECS Controls

New APECS controls improve performance with the following:

  • Torque shift management - allows the truck to power through shift points

  • Part throttle shifting - provides an exceptionally smooth ride

  • ECPC - electronically controls clutch pressures for long life


Cat C27 ACERT


  • 5% more power gives the truck new performance levels and quick haul cycles

  • Cat MEUI™ injectors provide high pressure, fine atomization under all load conditions for fuel efficiency and responsiveness

  • Low pressure fuel lines from the tank to the engine simplify service

  • The C27 is carefully balanced with vibration controls that reduce noise and protect against unnecessary harmonics

  • Cooling is provided by either a demand fan (standard for Tier 4 Final machines) or a conventional cooling fan

  • Ground level engine shutdown switch for safety

  • Excellent high-altitude capability (see specifications for details)


Steering


  • The steering linkage is designed to provide feedback to the operator

  • The Cat king pin front suspension system maintains steering tolerances and tire alignment


Brake Performance

Cat trucks provide powerful, fade-resistant braking for off road applications, and G Series introduces new ways to extend your brake life.

  • Rear brakes are wet disc while the front are dry, caliper type

  • Slope holding capability benefits from all wheel parking brake actuation

  • Brake life can be extended by choosing the optional Cat Engine Brake

  • Additional springs in the design reduce wear and increase service life

  • A brake wear indicator keeps you informed of maintenance timing

  • Extended life brake material is available for extreme applications




Cutting Your Fuel Costs

           

The 773G introduces several key fuel conservation features:

  • Auto Neutral Idle - as the 773G idles in a forward gear, the transmission will automatically slip in and out of a neutral state to avoid stalling the torque converter and increasing fuel consumption.

  • Engine Idle Shutdown - when your G Series truck is in park and idles for more than a preset time, the truck will initiate engine shutdown to conserve fuel. This feature can be time adjusted or turned on or off according to your specific needs.

  • Speed Limiting - while you can continue to gear limit your G Series trucks, Caterpillar offers speed limiting that allows the truck to travel at a more fuel efficient engine speed and gear selection.

  • Transmission Controls - New APECS transmission controls increase fuel efficiency by maintaining momentum and speed on grade.


Economy Modes


  • Standard Economy Mode - G Series has the ability to adjust engine power based on your site, fleet and economic conditions. You can manually control fuel burn by adjusting the power down between 0.5 and 15 percent.

  • Adaptive Economy Mode - New for G Series - this economy mode requires a baseline for production from you using the Advisor display. As the truck transits the haul cycle, it is constantly evaluating its ability to meet your baseline in a reduced power setting. Where full power is needed, full power is applied, where reduced power works, reduced power is applied. It's fully automatic with no special operation required.





Overview

G Series represents a new era for the 773, and with your long-term success as our goal, we've developed this truck to be more productive and economical. It offers your operators the confidence, comfort and control to run at peak efficiency, and it can feed your crushers and haul material at a lower cost per ton. When you also consider its performance and fuel efficiency, the 773G is the right truck for our generation.
