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 fittings 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 configured with proportional auxiliary hydraulics, include the ability to adjust the flow for even greater tool control. Especially useful with tools such as angling ditching buckets.

Thumb Ready Stick (North American Builds)

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

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 fluid 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 confidence over a range of terrain and applications.

Dozer Float

Ground levelling and finishing applications are fast and easier with the dozer float function engaged making site clean-up much more efficient.

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 configure 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.

The Cat 302.4D cab is amongst the largest in the industry. The flat cab floor 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. ‘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.

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.

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 efficiently work on the machine when required. The main hydraulic valve and lines are also easily reached through a removable floor 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 floor plate are easy to remove and provide unhindered access to all internal hydraulic components.
