The Cat® 302.4D provides power and efciency so that you can get the best out of your

job without ever feeling the strain. You can be assured of faster, more powerful digging
with a smoother response.

3

Versatility

Flexible and functional for all jobs.

High Flexibility

Compact in size and with a transport weight under
2300 kg (5,070 lb), the 302.4D can be transported
easily using a conventional trailer and pick up truck
or transit van.

The sturdy hoisting eyelets on the cab roof enable
the easy and rapid relocation of the machine
between sites.

Automatic Swing Lock

Safe transportation of the machine is aided by the
Cat automatic swing lock which locks the machines
upper body in place when the control console is
raised or the engine is stopped.

Work Tools

A variety of purpose designed work tools are available, including buckets, quick couplers,
hammer and auger. All Cat tools are built to last and matched to your machine to deliver
excellent value and optimize performance.

Auxiliary Hydraulics as Standard Fit

Machine is ‘ready to work.’ Hammer and two way lines complete with quick disconnect
ttings are standard. Connections are located close to the tool to reduce hose lengths and
any potential damage. Additional line options are available to further increase machine
versatility. Stick and bucket cylinder hoses are protected byrouting them through the boom.

Auxiliary Flow Control

Machines congured with proportional auxiliary hydraulics, include the ability to adjust
the ow for even greater tool control. Especially useful with tools such as angling ditching
buckets.

Thumb Ready Stick (North American Builds)

The 302.4D is congured with brackets and relief valves for simple and cost effective
mounting of a hydraulic thumb.

4

Built Tough

The front end of the 302.4D is designed
forhard work. Its rugged construction and
protected hydraulics ensure that the machine
is up to the toughest of jobs. Steeltubes,
positioned above the boom supply the
hydraulic uid to the tools, ensuring
protection from damage while keeping
anymaintenance quick and easy.

Components have been located to ensure
the best possible machine center of gravity
and weight distribution and give operator
condence over a range of terrain and
applications.

Performance

Powerful operation and greater uptime.

Dozer Float

Ground levelling and nishing applications are fast and easier
withthe dozer oat function engaged making site clean-up much
more efcient.

Dig Force

The 302.4D boasts high bucket and stick forces making it an
impressive and productive excavator.

The choice of two stick lengths allows the customer to congure
hismachine to deliver even higher stick forces or longer reach.
Youhave the choice, we have the solution.

All hydraulic functions are fully pilot operated, delivering
effortless operation, reducing maintenance and lowering owner
operatingcosts.

5

The Cat 302.4D cab is amongst the largest in the industry. The at cab
oor optimizes visibility and increases operator leg room. The ergonomic
control layout provides a comfortable, highly productive workspace.

The large two-part front windscreen allows the driver to slide both lower
and upper panes beneath the cab roof, so protecting them from damage
when the front screen is wide open. This also negates the need to
remove or store the bottom windscreen pane away separately.

100% Pilot Controls

All hydraulic functions are fully pilot operated, delivering effortless
operation, reducing maintenance and lowering owner operating costs.

2 Way Canopy Access

Canopy builds allow the operator to enter and exit
the operator station from both sides of the machine,
helping to increase productivity and making working
around site much easier.

‘As new’ machine controllability is maintenance free without the need
for adjustment of linkages or cables.

Auxiliary and boom swing services are controlled by proportional
switches mounted on the joysticks.

6

Productive Comfort

Large operator environment and ergonomic control layout.

7

Maintenance and Service

Easy access and minimal maintenance
requirements keep you working.

Unmatched support makes the difference

Your Cat dealer is ready to assist you with your purchase decision and everything after.

• Financing packages are exible to meet your needs

Easy Maintenance and Service

All daily checks and regular service points, are easily accessed.

A large steel rear door and removable panels allow room to efciently work on the machine when
required. The main hydraulic valve and lines are also easily reached through a removable oor plate
andside panels.

Durable steel body panels all round the machine offer good resistance to damage and are easily
maintained to help keep the machine looking good andholding its value.

Both side plates and the cab oor plate are easy to remove and provide unhindered access to all
internalhydraulic components.
