PC228USLC-3 Series Hydraulic Excavator

Working in congested or confined areas can be a challenge. Komatsu’s PC228USLC-3 SeriesHydraulic Excavators have a short tail swing profiledesigned specifically for work in confined areas. By reducing tail swing, thePC228USLC-3 can work in areas where conventional profile excavators wouldpose a safety risk. Perfect for work on roadways, bridge work, urban areas, oranywhere space is limited, the PC228USLC-3 provides you with performance andproductivity you expect from Komatsu equipment.

Larger cab● Komatsu’s low noise design

incorporates a fully pressed, highly-rigid cab that utilizes viscous cabmounting.

● A sliding convex door facilitateseasy entrance in confined areasand reduces the danger of beingdamaged on roadways becausethe door does not protrude whenopen.

● Komatsu’s large cab meets ISOworking space standards toprovide secure, safe, andcomfortable operation.

Wide working ranges● Maximum digging height of the

PC228USLC-3 is larger than that of thePC200LC-7. Raising the boom on thePC228USLC-3 to a wider angle enhancesoverall working performance. Job sitesthat require a long upper reach, such asdemolition and slope cutting benefitfrom the increased digging anddumping ranges of the PC228USLC-3.

High mobility● Large drawbar pull and steering force display

its ability when operating on a slope.

Operator’s CabMulti-Position Controls

The multi-position, pressure

proportional control levers allow

the operator to work in comfort

while maintaining precise control.

A double-slide mechanism allows

the seat and controllers to move

together or independently, allowing the

operator to position the controllers for

maximum productivity and comfort.

Cab Mount

The cab rests on viscous damping

mounts to reduce vibration and noise

from the machine body. The result is

reduced operator fatigue.

Noise

Komatsu’s low noise design

incorporates a fully pressed highly-rigid

cab that utilizes viscous cab mounting.

Sliding Convex Door

The sliding convex door facilitates

easy entrance in confined areas

while reducing the danger of being

damaged on roadways because the

door does not protrude when open.

The cab also features a sliding

window on the door.

Washable Floor

The PC228USLC-3’s floor is easy to

keep clean. The gently inclined surface

has a flanged floormat and drainage

holes to facilitate run-off.

The PC228USLC-3 cab interior is spacious and provides a comfortable working environment…

Large Capacity Air Conditioningand Heating Unit

The PC228USLC-3 air conditioner

capacity is 43% greater than the

PC228USLC-2. The bi-level controls

provide cool air to the operator’s head

and warm air to the feet allowing

comfort throughout the year. The

defroster function keeps the front glass

clear.Capacities

Easy MaintenanceKomatsu designed the PC228USLC-3 to have easy service access. By doing so, routine maintenance and servicing are less

likely to be skipped, which can mean a reduction in costly downtime later on. Here are some of the many service features found

on the PC228USLC-3:

Optimum Maintenance Layout

Effortless access to engine-related maintenance items such as oil

filter, oil dipstick, coolant reserve tank, fuel filter, and air cleaner.

New Hydraulic Filter Element

The new hydraulic oil filter uses high performance filtering

material for long element replacement intervals, which

significantly reduces maintenance costs. The new hydraulic filter

extends the element replacement interval to 1000 hours and keeps

the hydraulic oil replacement interval at 5,000 hours. Its small size

reduces waste material.

Long greasing Interval

Special material is used for the bushings of the work equipment to lengthen greasing

intervals. All bushing lubrication intervals of the work equipment, excluding the bucket

connection, are extended from 100 hours to 250 hours, reducing maintenance costs.

Safety Features

Side-by-Side Cooling

The oil cooler and aftercooler which

previously were installed in front of the

radiator are installed side by side. As a result,

it is very easy to clean the radiator, etc.

Removal and installation of the radiator and

oil cooler can now be done independently.

Water Separation

A Water Separator is standardequipment, removing water mixed in fueland preventing fuel system damage.

Steps with non-skid sheetsprovide improved footing formaintenance.

A Large handrail is installedto aid in getting on/off themachine safely.

EMMS (Equipment Management Monitoring System)

Monitor FunctionThe controller monitors engine oil level,coolant temperature, battery charge, airclogging, etc. If the controller finds anyabnormality, it is displayed.

Maintenance FunctionThe monitor informs replacement time ofoil and filters when the replacementinterval is reached.

Trouble Data Memory FunctionThe monitor stores abnormalities foreffective troubleshooting.
