Benefits and Features

Compact Radius

Configured without the additional counterweight the 302.7D CR is a true zero tail swing machine with the upper body staying within the width of the undercarriage during rotation. This enables the operator to work within confined areas and concentrate on the work being performed without having to worry about the back of the machine.

Transport Weight

The 302.7D CR is designed with a transport weight below 2.7 tonnes (6,000 lb) with cab fitted. This allows lower trailer transportation costs using a standard passenger vehicle (subject to national restrictions).

Additional Counterweight

An optional additional weight increases the machines lifting capability with only a small addition to the overhang. An optional additional counterweight increases the machines lifting capacity with only a small addition to the overhang. (This counterweight is fitted as standard for North America and Australia)

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 lines options are available to further increase machine versatility. Stick and bucket cylinder hoses are protected by routing them through the boom.

100% Pilot Controls

Delivers excellent machine control and lifetime ‘as new' performance eliminating the need for linkage and cable maintenance.

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.

Thumb Ready Stick (North American Builds)

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

Dozer Float

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

Cab Comfort

The Cat® 302.7D CR gives the operator a large comfortable space in which to work. The ergonomic control layout, travel pedals and adjustable wrist rests are engineered to minimize operator fatigue and increase productivity.

Simultaneous Operation

Both machine upper body swing and boom offset can be controlled simultaneously for faster machine positioning and object handling.

Adjustable Flow Control

Machines configured with proportional auxiliary hydraulics include adjustable hydraulic flow control for even greater tool control. Especially useful with tools such as angling buckets.

Split Front Window

The lower front window section slides into the upper section frame. Both sections are then raised and stored in the roof using a gas assisted mechanism. This allows the operator to position the front window to suit their visibility and ventilation requirements with easy storage.

Pivot Bushing

Steel bushings are fitted on all front linkage pivot points including the swing casting, boom, stick and bucket. Designed for long life and easy replacement.

Maintenance Access

Removable covers in the cab and at the rear of the machine provide easy access to hydraulic system components.

Side Mounted Engine

All daily service points are easily accessed through the large side cover. The engine position also reduces heat and noise transfer into the operator station (cab).
