Key Features & Advantages

1. High Efficiency & Low Operating Cost

The PC30 is equipped with Komatsu's proprietary power matching system, which optimizes engine output and hydraulic response to cut energy loss, delivering 10% lower fuel consumption than older-generation models of the same class. Its aftertreatment system only uses a Diesel Oxidation Catalyst (DOC), eliminating the need for a Diesel Particulate Filter (DPF) and active regeneration, greatly reducing daily maintenance costs and downtime.

2. Ultra-Compact Short-Radius Design

The MR (Mini Radius) variant adopts a short tail swing design: the rear overhang of the upper structure does not exceed the track width during rotation, allowing safe operation in extremely narrow spaces such as urban alleys, indoor demolition sites, small residential yards and greenhouse interiors. Its narrow body can be transported via small trailers, and even enter construction sites through standard elevator openings.

3. Operator-Friendly & Safety Compliance

The cabin or canopy is fitted with ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) as standard, meeting global construction safety regulations.
Low-effort pilot control joysticks have short travel and smooth feedback, reducing operator fatigue during long working hours.
The large panoramic front window provides unobstructed visibility of the bucket and working area, improving operation accuracy and safety.
Optional air conditioning, heating and noise reduction modules keep the operating environment comfortable even in extreme weather.

4. High Reliability & Easy Maintenance

Reinforced boom, arm and undercarriage components are designed for heavy-duty working conditions, extending the service life of structural parts.
All daily maintenance points (engine oil filter, fuel filter, air filter, hydraulic oil level gauge, etc.) are arranged on the side of the machine for ground-level access, no need to climb the machine for routine servicing.
Optional Komatsu KOMTRAX telematics system supports remote monitoring of equipment location, fuel consumption, maintenance reminders and fault alarms, making fleet management more efficient.

5. Strong Versatility

The PC30 is pre-configured with auxiliary hydraulic lines, and can be fitted with a quick coupler to switch between multiple attachments in minutes, adapting to diverse work scenarios:

Hydraulic breaker for demolition work
Auger for tree planting and pole hole drilling
Grapple for waste handling and stone loading
Trencher for cable and pipeline trenching
Sweeper, lawn mower, snow plow for municipal maintenance work

Typical Applications

Urban municipal engineering: Sidewalk repair, water pipe/cable trench digging, road surface maintenance, public facility renovation
Landscaping and gardening: Terrain leveling, tree pit digging, landscape stone handling, garden construction
Small construction projects: Residential foundation excavation, small building demolition, construction waste removal
Agricultural operations: Orchard ditching for fertilization, greenhouse land preparation, livestock farm waste cleaning
Confined space work: Indoor demolition, basement construction, factory interior renovation

Optional Configurations

Rubber track / steel track, tracks of different widths
Extended boom and arm for larger working range
Quick attachment coupler
Various specialized work attachments
Closed cabin with air conditioning / heating
Rear view camera, rotation warning alarm
KOMTRAX remote monitoring system
Additional auxiliary hydraulic lines for high-flow attachments

Brief Summary

The Komatsu PC30 series mini excavator balances performance, durability, flexibility and operating cost, making it an ideal choice for small and medium-sized construction operators. Supported by Komatsu's global after-sales service network and abundant spare parts supply, it also boasts a very high resale value in the second-hand equipment market, with a low total cost of ownership throughout its service life.
