Used Compact Excavator CAT 308C
Product Information
The used CAT 308C is a compact crawler excavator for construction, utility, road, and landscaping work. Its compact-radius body helps it operate where working space is limited. At the same time, the steel undercarriage provides a firm base for digging and loading.
Longmai Machinery supplies used construction equipment to contractors, machinery dealers, rental firms, and fleet owners. Buyers can request current photos, operating videos, condition details, and inspection support. In addition, our team can help with machine preparation, export documents, loading, and shipping.
Compact-Radius Design for Busy Sites
The CAT 308C uses a compact rear design. Therefore, the upper body needs less space when it swings. This feature is useful near buildings, walls, roads, fences, and other site limits.
Moreover, the machine is small enough for many urban and commercial jobs while still offering the strength of an 8-ton-class excavator. It can dig trenches, prepare foundations, grade soil, and load loose material.
The pictured unit includes an enclosed cab, steel tracks, a front blade, and a digging bucket. However, the final attachment and machine setup depend on the selected unit.
Engine and Hydraulic Performance
Reference CAT 308C configurations use a four-cylinder Mitsubishi 4M40-series diesel engine. Net power is about 40.5 kW at 2,000 rpm. As a result, the excavator can provide steady power for daily digging and loading work.
The hydraulic system supports smooth boom, stick, bucket, swing, and blade movement. In addition, auxiliary hydraulic lines may be fitted for compatible work tools. Buyers can therefore discuss options such as a breaker, auger, grapple, or different bucket.
Reference digging force is about 56.9 kN at the bucket and 37.3 kN at the stick. Consequently, the machine can handle soil, clay, gravel, and similar jobsite material.
Steel Undercarriage and Front Blade
The steel crawler undercarriage gives the excavator broad ground contact. Therefore, it can maintain a stable base on soil, gravel, and uneven ground.
Travel speed is approximately 3.0–5.0 km/h, while swing speed is about 10 rpm. These figures support practical movement and short digging cycles on active sites.
The front blade adds more value. For example, it can level soil, fill trenches, clear loose material, and support the machine during digging. As a result, contractors can complete several site tasks with one machine.

Because the machine combines a compact body with useful digging power, it is suitable for buyers who handle different types of small and medium projects.
Inspection and Machine Preparation
Before an order is confirmed, buyers can request current machine photos, an operating video, and available unit records. The inspection can cover the engine, hydraulic system, cylinders, boom, stick, bucket, swing system, blade, travel motors, cab, and undercarriage.
Furthermore, a buyer-appointed or third-party inspection may be arranged. Cleaning, fluid checks, minor repairs, paint work, and attachment matching can also be discussed.
Since this is used equipment, normal wear may be present. The production year, working hours, serial number, service history, attachments, and final condition should be listed in the quotation.
