Motor Graders
Basic Application Benchmarksand Operating Techniques
MOTOR GRADERS Basic Application Benchmarks and Operating Techniques 41
MOTOR GRADERS
Favorable Applications:
• Haul road construction/maintenance • Selected load area cleanup• Selected dump area maintenance• Blasting cleanup• Reclamation• Snow removal• Utility ripping
Things to watch for:
• Grade in 2nd or 3rd gear: 6 - 11 km/h (4 - 7 mph)• Use wheel lean and articulation to reduce turning radius • Rip in first gear; manually operate throttle• Excessive speeds negatively affecting cutting edge life• Change cutting edges when down to 10 mm (0.5 in)• Use ripper attachment to rip hard-packed top surface• Always using differential lock when blading and ripping
MOTOR GRADERS Basic Application Benchmarks and Operating Techniques 43
MOTOR GRADERS
Things to watch for:
• Maintain full blade contact with floor to avoid high point loading
• Consider using track-type tractors or wheel dozers for assistance when unable to maintain full blade load
• Use wheel lean to hold front of machine in line, reduce side draft forces, and help reduceturning radius
• Always use differential lock when blading in a straight line
Proper blade angle:• Use widest possible pass width• Reduce pass width (increase angle) if material flows
around leading edge (toe)• Use maximum 10° blade angle if using Graderbit system
or serrated edge• Maintain contact with road
surface across the full width of the cutting edge
Proper blade tip angle:• Moldboard top should be 50 - 100 mm
(2 - 4 in) ahead of cutting edge on Cat® 16H and 24H motor graders
• Constant tip angle minimizes cutting edge wear Cut

TRACK-TYPE TRACTORS
Favorable Applications:
Sizing Tractors for the Truck Dump:
Optimal track-type tractor – truck matchups:
• Production dozing • Dedicated waste dump operations • Stockpile operations/steep slopes • Haul road construction• Reclamation • Ripping
DOZING APPLICATIONS
D9 777
D10 777/785/789
D11 789/793/797
Things to watch for:
• Excessive tramming between locations
• Tramming less than 5% of tractor’s work time
• Loose or missing track hardware
Things to watch for:
• Dozing in 1st gear• Steering with blade
tilt cylinders rather than steering clutches when blade is loaded
• Minimized corner loading, prying, and impact dozing
• Maintain a steady dozing pressure
• Keep unloaded travel distance to a minimum
Basic Application Benchmarks and Operating Techniques 49
TRACK-TYPE TRACTORS
DOZING APPLICATIONS
Back Each Pass Technique(Less Efficient Technique)
• Operator starts each pass at the back of the cut
• Each pass uses theentire length of the cut at a uniform depth
• Efficiency and productivity suffer because the machine travels the entire length of the cut in both directions with each pass
Back to Front Technique(Less Efficient Technique)
• Operator progresses the cut from back to front
• Push distance is reduced with each pass
• Efficiency suffers from uphill blade loading
• Does not fully utilize the slot throughout the cutFront to Back Technique
(Most Efficient Technique)
• Most efficient method of dozing• Works cut from front to back• Push distance increases with
each pass• Uses more efficient downhill
blade loading• Slot is created and utilized
throughout the cut
TRACK-TYPET R A C T O R S
Basic Application Benchmarks and Operating Techniques 51
TRACK-TYPE TRACTORS
Berm Management• Berm height should not
exceed blade height• Berm should only be high
enough to trap material for optimal loading
• Center berm width should be 1/3 the blade width
• The smaller the berm, the easier the disposal for improved productivity
Criss/Cross Berm Removal• Most efficient method
of center berm removal• Works cut from back
to front• Push distance reduces
with each pass• Uses existing slots to hold
in material and increase blade load
Blade positioning on dual tilt machines:
• Begin cut with blade tilted forward• Begin to lay blade back when nearly full• Continue to fill blade while lying back• Tilt blade forward to unload material
TRACK-TYPET R A C T O R S
DOZING APPLICATIONS
TRACK-TYPET R A C T O R S Basic Application Benchmarks and Operating Techniques 53
TRACK-TYPE TRACTORS
RIPPING APPLICATIONS
Things to watch for:
• Rip downhill when possible• If loading scrapers, rip material
in same direction as loading• 1.5 - 2.5 km/hr (1.0 - 1.5 mph)
at 2/3 throttle is most economical• Reduce speed in high impact conditions• Try cross ripping if material
will not free up
Ripper position:• Begin pass with tip rearward• Pull tip forward after tip penetrates
Signs of incorrect positioning/operating:• Excessive track slippage• Blunt tips (GET)• Breaking shank protector or ripper tip pins
Ripper Ground Engaging Tools:• Penetration ripper tip reinforcing ribs must face upward • Ensure ground engaging tool pins, retainers, and bolts
are installed correctly• Never operate a bare shank or worn tip

HAUL ROADCONSIDERATIONS
HORIZONTAL AND GENERALVERTICAL ALIGNMENT
Three key factors in haul road design:• Material Quality• Design• Maintenance
Rules of thumb:
• If you can comfortably travel your haul roads at 60 km/h (35 mph) in a light vehicle, this is an indicator of good haul road conditions
• Haul roads begin at the loading face and end at the dump
• Maintain good floor conditions approaching and at the dump
• Maintain good floor conditions approaching and at the face
• Travel at reasonable speeds in the load and dump zones
Things to watch for:
• Design corners and crests with clear visibility at operating speeds
• Design for worst case scenarios

CROSS FALL KEEP GRADE SMOOTHAND CONSTANT
On flats:• Maintain minimum
slope for drainage• Use 2% constant
cross fall with extreme caution and travel loaded truck on the “uphill” side
• If constant cross fall is not selected, crown haul roads with minimum slope angle
On grades:• Minimal cross fall
is required unless rainfall is heavy
Smooth, constant grades:• Grades less than 10% are recommended for maximum tire life• Consistent grades should be maintained� Minimize transmission shifts� Maintain higher average speed� Allow more constant braking effort on returns

Radius:
• Use maximum practical radius
• Keep constant and smooth transitions
Superelevation:
• Employ if speeds exceed 15 km/h (10 mph) as per Performance Handbook
• Greater than 10% superelevation should be used with caution

DRAINAGE SAFETY BERMS (WINDROWS)
Things to watch for:
• Slope must adequately carry away maximum expected rainfall, with minimum puddling, pot-holing or water entry into road sub-base
Things to watch for:
• Recommended berm height is a minimum of half the wheel height
– Safety berm along the edge of the truck dump– Safety berm along all haul road edges
• Check your local mining regulations

HAUL ROAD MODELING ROLLING RESISTANCE
These are examples of a
poorly constructed haul road
(top) and a well constructed
haul road (bottom)
Top:• Poor drainage• Poor compaction• Poor road base material
Bottom:• Good drainage• Good compaction• Good road base material
Tire Penetration
For off-highway trucks running radial-ply tires,assume a minimum rolling resistance of:
• 1.5% for a hard, well-maintained, permanent haul road• 3% for a well-maintained road with little flexing• 4% for a road with 25 mm (1 in) tire penetration• 5% for a road with 50 mm (2 in) tire penetration• 8% for a road with 100 mm (4 in) tire penetration• 14% for a road with 200 mm (8 in) tire penetration
In practice, a 5% increase in rolling resistance can result in up to10% decrease in production and a 35% increase in production costs.

SOFT AND WET AREAS
An example of highrolling resistance• 610 mm (24 in) deep tire
penetration• 30% rolling resistance• Reduced production• Excessive fuel burn• Reduced tire life• Reduced component life
Things to watch for:• Remove soft and wet
spots; completely refill and compact with good dry material
• Without a good repair, these spots will continually deteriorate

DESIGN ANDMAINTENANCE
• The haul road begins at the loading face and ends at the dump point
• Once a road deteriorates, it takes five times as long to repair it to good condition again“Fix it once, fix it right!”
• If one can travel comfortably in a light truck at 60 km/h (35 mph), then road surfaces are good
• Good roads improve production, extend tire life, and reduce overall operating costs
Basic Haul Road Design and Maintenance 77
MINE HAUL ROADS
DUST CONTROL
• Watering removes dust hazard and maintains compaction
• Use “checkerboard” or “spot” intermittent pattern on grades to reduce slippage risk during retarding on grades
• “Spot watering” works well for areas with limited water supply
POINTS TO REMEMBER
CAT® GLOBAL MINING
Basic Truck Dump Design
and Maintenance
TRUCK DUMPO P E R AT I O N Basic Truck Dump Design and Maintenance 81
TRUCK DUMPS
• Body bulldozing– Pulling through berm
after dumping is hard on underside of the body
• Dumping into existing pile– Not lowering body
prior to moving forward
Damage Indicates:• Pulling through pile• “Pinching” material
under tail• Pushing with a dozer• Poor dumping practice
can result in rear rib and tail area damage
Things to watch for:
• Maintain eye contact with dump maintenance tool whenever possible
• Watch dump edge for stability• Dump away from safety berm if edge
is unstable (dump short)• Maintain proper safety berm height• Lower body before moving from dump• Advance haul road with dump• Maintain slight slope for water drainage

Incorrect
GROUND ENGAGINGTOOLS (GET)
Things to watch for: GET• Use the best option for the application
to maximize production• Protect, but do not overprotect
– Increases bucket/implement weight– Decreases payload– Affects GET component life– Reduces penetration and productivity– Better penetration reduces fuel
consumption– Adversely affect operating techniques
• Replace components when they reach 100% wear
– Helps penetration thereby increasing bucket fill factor
– Better penetration reduces fuel consumption and tire slip
– Use worn GET wear patterns as a condition monitoring tool to manage operating techniques
HYDRAULIC BACKHOES
Things to watch for: GET• Maintain proper bench height• Load square to the face• Avoid excessive prying or corner loading• Maximize GET* tip contact
(i.e., boom up and curl bowl through material)– Minimizes bowl contact– Keeps heel clear of the material– Keeps bucket throat open
• Use “boom up” to minimize bucket heel contact• Never operate with blunt GET or bare bucket edge

Things to watch for:• Grade in 1st gear• Determine drainage pattern
prior to grading• Obtain road bed material
sufficient to slope road• Always keep edges sharp
for better penetration• Change edges prior to
moldboard damage• Always lock differential
when grading or ripping• Always perform articulated turns with wheel lean to reduce turning radius
Proper blade angle:• Use widest possible pass width• Reduce pass width (increase angle) if material flows
around leading edge (toe)• Use maximum 10° blade angle if using Graderbit system
or serrated edge• Maintain contact with road
surface across the full width of the cutting edge
Proper blade tip angle:• Moldboard top should be 50 mm
(2 in) ahead of cutting edge • Constant tip angle minimizes

HAUL ROADCONSIDERATIONS
Three key factors in haul road design:• Material Quality• Design• Maintenance
HORIZONTALAND GENERALVERTICAL ALIGNMENT
Things to watch for:• Design corners
and crests with clear visibility at operating speeds
• Design for worst case scenarios
KEEP GRADE SMOOTH AND CONSTANT
Smooth, constant grades:• Grades less than 10% are recommended for maximum tire life• Consistent grades should be maintained�Minimize transmission shifts�Maintain higher average speed�Allow more constant braking effort on returns
SAFETY BERMS (WINDROWS)
Things to watch for:• Recommended berm height is a minimum of half
the wheel height– Safety berm along the edge of the truck dump– Safety berm along all haul road edges
• Check your local mining regulations
UNDERGROUNDA P P L I C AT I O N S Caterpillar Underground Machines 119
ROLLING RESISTANCE
For off-highway trucks runningradial-ply tires, assume a minimumrolling resistance of:
• 1.5% for a hard, well-maintained, permanent haul road
• 3% for a well-maintained road with little flexing
• 4% for a road with 25 mm (1 in) tire penetration
• 5% for a road with 50 mm (2 in) tire penetration
• 8% for a road with 100 mm (4 in) tire penetration
• 14% for a road with 200 mm (8 in) tire penetration
In practice, a 5% increase in rolling resistancecan result in up to a 10% decrease in productionand a 35% increase in production costs.

*Ballast weight for bias ply tires from Goodyear data, radial ply weights from Michelin data. Contact your tire supplier for additional information. Under abnormal tire wear conditions, ballasting of rear tires may be desirable. Ballasting of front tires also should only be done where extremely rapid tire wear rates are encountered. Excessive weight will reduce machine performance.
**1.6 kg (31⁄2 lb) Calcium Chloride per gallon water. Solution weighs 4.6 kg (10.15 lb) per gallon.
***Fillage beyond 75% of tire enclosed volume is not recommended. With liquid ballasting, inflation pressure must be checked at least once per day.
NOTE: When liquid ballasting telehandler tires, consult Telehandler’s Operation and Maintenance Manual for requirements.Total machine mass including all attachments in operating condition, all reservoirs at full capacity and ballasted tires must not exceed certification mass listed on the ROPS certification label.
