TRIMBLE 2D GRADE CONTROLSYSTEMS FOR SMALL SITES
Trimble’s productivity-enhancing Grade Control
Systems are scalable and can be configured for justabout any machine or job. All Trimble Grade Control
components have been designed for ease of use,quick setup and extreme durability to ensure thehighest uptime and longest life possible.
Connected Machine functionality is
included in all 2D Grade Control Systemsfrom Trimble. Connected Machine
solutions decrease machine downtime, and canreduce rework and miscommunication by wirelessly
sending data between the machine and the office.
When combined with VisionLink®, Trimble’s asset,
fleet and site productivity management software,
you get better control of your fleet and your site.

Grading
An excellent first investment for contractors new toconstruction technology.
A single laser and laser receiver are used to measure thelift and tilt of the blade. To measure the slope of the blade,
add another laser receiver or a slope sensor. An in-cab
Trimble CB450 or CB460 Control Box provides elevationand slope guidance, so you can more accurately andquickly get to grade.
Trimble 2D Grade Control can easily be upgraded toa 3D Grade Control System.

2D Grade Control gives you precise vertical guidancenecessary to achieve tight tolerances and a smoothfinished grade.

Ideal for earthmoving contractors looking to improve theirexcavation productivity and profitability.

Two angle sensors and a rotation sensor can be used infinished grade applications to calculate the cross-slope ofthe blade. Adding a laser receiver or a sonic tracer gives you
the ability to measure elevation when required. Additionally,
when using the a sonic tracer, the system allows forstringline, previous pass, or curb and gutter tracing.

Trimble 2D Grade Control uses an angle sensor, dual
axis sensor and laser catcher to measure the relationshipbetween the body, boom, stick and bucket. This
determines where the bucket teeth are, and where theyshould be, to guide the operator to the desired depthand slope.
The system also offers the flexibility to upgrade to a
3D Grade Control System.

Ultimate Productivity
TRIMBLE 3D GRADECONTROL SYSTEMS
From bulk earthmoving through grading tofinished material compaction, Trimble has a 3D
Grade Control solution for your machine typeand application requirements. Ask your SITECH
distributor about the appropriate 3D sensor
option—GNSS or total station-based systems—
then use the same components across your entire
fleet, through the life cycle of the project.
All Trimble 3D Grade Control Systems
come standard with Connected Machinefunctionality. Wirelessly transfer data
between the office and the machine, and manage
asset, fleet and site productivity with VisionLink
software powered by Trimble.

Bulk Earthworks
Design information and live cut/fill indications are
displayed in the cab, allowing excavation to be done ina safer, stakeless environment.
The system provides real-time information for monitoring
avoidance zones and simultaneously collects as-built
data as the machine cuts to grade. With these capabilities,
operators can keep tighter control over safety issues
and see precisely where dirt is being moved on site.
XX MACHINE TYPES: dozers, excavators, motor graders

and wheel loaders
XX COMMON APPLICATIONS: land reclamation, dam andreservoir construction, new infrastructure projects,
landfills and waste deposits

Grading
Get to grade faster and more accurately than ever, even withcomplex designs.
The on-board Trimble control box determines the position ofeach tip of the blade and compares it to the design elevation
to compute cut or fill to grade. The cut/fill data is used to drive
the valves for automatic blade control, or is shown on in-cablightbars that provide visual guidance for manual operation.
XX MACHINE TYPES: dozers, graders, excavators, scrapers andcompact grading attachments
XX COMMON APPLICATIONS: Highway and railway construction,and residential and commercial site construction.

Compaction

Finished and Fine Grade

The Trimble CCS900 Compaction Control System
helps you accurately control the compaction process,while reducing unnecessary passes that result inover compaction.

Achieve finished grade to millimeter accuracy withfewer passes.

The system achieves target compaction faster,
more accurately, with less rework. The early detectionof unsuitable materials and hidden obstructions canbe excavated and re-graded or compacted prior tomore costly phases of the construction process.
Compaction results are recorded and stored for analysis
and generation of documentation deliverables at theend of the project.
XX MACHINE TYPES: two-drum and four-drum

soil compactors
XX COMMON APPLICATIONS: highway and railway
construction, residential and commercial site
construction, parking lots and sports fields022482-2511D_GCS900_Brochure_043018.indd 7

By maintaining tight tolerances every time, a GCS900
system results in higher quality work delivered to theclient. Finished grade materials can be placed moreaccurately and in a shorter time period, keeping thematerial costs to a minimum and realizing better profits.
With more confidence in the cost of operations andquicker completion to finished grade, the equipment
owner is able to lower bids and gain more business inevery phase of the project.

Solution Components
Connected Machine
Now standard in all Trimble Grade Control Systems,
the Trimble Connected Machine solution helps
contractors manage their assets and see whatmachines are doing. Machines can collect asbuilt measurement data for office delivery, and receive GNSS
corrections using the Internet. A 3D design created in the officecan be sent to the machine operator for faster, more precise
grading and earthmoving. Support can be delivered remotely,
without ever leaving the office. Additionally, the machine can beused for volume measurements, so expensive measurements bygrade checkers occur less frequently. Drive time and rework arealso minimized, as both the office and machines in the field are
kept up-to-date with the latest information.

Connected OfficeThe Trimble Connected Office solution allows
contractors to create 3D construction models,perform data preparation and takeoff, wirelessly
sync data, monitor site productivity, and manage
fleets and assets. The 3D design model created in the officecan be sent to machines and controllers in the field, increasing
efficiency, reducing rework and saving money. Additionally, acomplete view of site productivity including materials quantity
and movement, volume and compaction data, and fleet andasset management information can be shared across theorganization to enable rapid decision-making and better
communication.

Connected Controller
The Trimble Connected Controller solution
wirelessly syncs Trimble Site Positioning Systems
in the field with the office and allows the Trimble
controller to receive GNSS corrections via theInternet. A grade checker can receive the design model, create
new measurements and then send the measurement andstakeout results back to the office for review. Design changes
originating in the office can also be sent to the controller so fieldcrews are rapidly updated with current information. All of thisis accomplished without personnel ever leaving the site or theirdesk, dramatically increasing productivity and reducing costs.
