The Used CAT 305.5 Mini Excavator combines compact dimensions with practical digging power for construction, landscaping, utility work, road projects, and general earthmoving.

With an operating weight of approximately 5,400 kg, this crawler excavator is easy to use on smaller jobsites while still providing the stability needed for excavation and loading work. In addition, its 0.22 m³ bucket, 3.2 m boom, and 1.5 m stick provide a useful working range for many daily applications.

The machine is powered by a Cat C2.4 DI four-cylinder diesel engine. Together with a hydraulic excavator system and crawler undercarriage, it offers a balanced combination of digging force, mobility, and control.

Compact Size for Flexible Jobsites

One key advantage of this used Caterpillar excavator is its compact body.

The machine measures approximately 5,765 mm long, 1,950 mm wide, and 2,540 mm high. Therefore, it can work more easily in areas where a larger excavator may have limited access.

Its compact dimensions are useful for urban construction, landscaping, utility installation, residential projects, and small roadwork.

At the same time, the crawler undercarriage provides a stable working base on soil, gravel, and uneven ground.

Cat C2.4 DI Diesel Engine

This configuration uses a Cat C2.4 DI diesel engine with a displacement of 2.4 L and four cylinders.

The supplied configuration lists rated power at approximately 34.1 kW. Published 305.5 references also list the C2.4 DI engine and show rated output figures that vary according to the measurement standard used.

The water-cooled engine is designed for construction equipment use. Moreover, the 78 L fuel tank supports practical daily operation before refueling is required.

Strong Digging Performance

The excavator provides a 35 kN bucket digging force and approximately 27.2 kN stick digging force.

As a result, it can handle common excavation tasks such as trench digging, foundation preparation, soil removal, material loading, and site leveling.

The maximum digging depth reaches approximately 3,720 mm, while the maximum digging radius is about 5,955 mm. This gives the operator enough working range for many small and medium construction projects.

0.22 m³ Bucket for General Earthmoving

The standard bucket capacity is approximately 0.22 m³.

This size offers a practical balance between digging capacity and machine size. It can be used for soil, sand, gravel, clay, loose stone, and similar materials.

Depending on the project, different buckets and compatible attachments may also be selected after confirming the machine's hydraulic and mounting configuration.

Stable Crawler Undercarriage

The steel crawler system helps distribute machine weight over a larger ground area.

Therefore, the excavator can maintain better stability on soft or uneven surfaces compared with wheeled equipment. The crawler design is particularly useful on construction sites, landscaping projects, rural work areas, and earthmoving jobs.

The two-speed travel system, with speeds of approximately 2.8 to 4.3 km/h, also allows the machine to move efficiently around the work area.

Comfortable Operator Cab

The enclosed cab provides wide glass areas for forward and side visibility.

Inside, the operator has access to hydraulic joysticks, operating controls, an adjustable seat, and machine monitoring instruments. The compact control layout helps simplify daily operation.

Good visibility is especially important when digging close to walls, loading trucks, working near underground utilities, or operating in confined spaces.

Typical Applications

The Used CAT 305.5 is suitable for a wide range of work, including:

Foundation and trench excavation
Residential construction
Road and drainage projects
Landscaping and land preparation
Utility pipe installation
Small demolition work
Farm and rural construction
Material loading
Site cleanup
Municipal engineering

Because of its compact size, it is also suitable for contractors who need one excavator for several different job types.

Why Choose a Used CAT Mini Excavator?

Buying a used mini excavator can help contractors increase equipment capacity while reducing initial investment.

A CAT 305.5 offers a useful middle ground between very small mini excavators and larger construction excavators. It is compact enough for restricted sites but still provides a 5.4-ton operating weight and strong digging forces.

For equipment dealers, rental companies, contractors, and overseas machinery buyers, this model can be a practical addition to an existing fleet.

Used Excavator Inspection

Before shipment, buyers should confirm the condition of the engine, hydraulic pump, control valve, boom, stick, bucket, cylinders, tracks, rollers, sprockets, electrical system, and operator cab.

Working hours, production year, serial number, maintenance history, and actual attachments should also be checked for the individual machine.

Because used equipment condition can vary, final specifications should always be confirmed for the exact unit ordered.
