Performance

Performance

Powerful digging combined with smooth control.

Stability

An extending undercarriage and fold out dozer blade allow the machine to be configured for optimum performance. Blade extensions are retained with the dozer making them easy to use and ensuring that they are not lost.

Dozer Float

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

Long Dozer Option

The optional longer dozer blade enables improved ‘dig to blade’ characteristics to give easier on site clean up.

100% Pilot Controls

Delivers excellent machine control and lifetime ‘as new’ performance eliminating the need for linkage and cable maintenance, lowering owning and operating costs and resulting in less downtime.

Dig Force

The new 301.7D 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 reach.

Versatility

Versatility

Flexibility built in for a variety of jobs.

High Flexibility

Compact in size and with a transport weight under 2000 kg (4,500 lb), the 301.7D 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 range of work tools are available including buckets, hammer and auger to take advantage of the machines versatility. All these tools are matched to the machine to optimize performance and deliver excellent value through productivity and long life.

Auxiliary Hydraulics as Standard Fit

Machine is ‘ready to work’. Hammer and two way lines complete with quick disconnect fittings as 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.

Productive Comfort

Productive Comfort

Large operator environment and ergonomic control layout.

Cab Comfort

The Cat 301.7D gives the operator a large comfortable space in which to work. The ergonomic control layout, travel pedals and adjustable wrist resets are engineered to minimize operator fatigue and increase productivity. The layout is designed for easy cleaning, minimizing downtime between jobs. There is a choice of cab with heater or canopy available. The canopy offering two sided access for even greater on site versatility.

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 in front window to suit their visibility and ventilation requirements with easy storage.

Engine and Serviceability

Engine and Serviceability

Superior power with easy access and minimal maintenance requirements keep you working.

Powerful Engine

The Cat 301.7D is fitted with a 17.9 kW (24.3 hp) gross power engine that is installed at a much lower rated 13.2 kW (17.7 hp). This is designed to reduce engine wear, give cooler running temperatures, with longer life and lower owner and operating costs.

Excellent Service Access

Daily checks and regular service points including fuel and hydraulic oil fill are easily reached via the large steel rear door. The main hydraulic valve and lines are also easily reached through a removable floor plate and side panels. The machine has durable steel body panels all around, offering good resistance to impact damage and helping to maintain the machine’s appearance and value.
