2. Key Performance Features

2.1 Ultra-high maneuverability

The compact body and minimal tail swing design support free operation in extremely confined spaces, including narrow urban alleys, indoor construction sites, gaps between buildings and small residential yards. It can be transported on a small light trailer, no special transit permit is required in most regions.

2.2 High-precision hydraulic system

Equipped with Komatsu’s proprietary closed-center load sensing hydraulic system (CLSS), it delivers smooth and precise control of boom, arm and bucket movements, with excellent fine operation performance for delicate tasks such as pipe laying, gardening planting and paving auxiliary work. The optimized hydraulic circuit reduces energy loss, and its fuel consumption is 10-15% lower than similar models of other brands.

2.3 Operator comfort

Two configuration options are available: open canopy and fully enclosed cab:

The cab version adopts ROPS/FOPS certified safety structure, with shock-absorbing adjustable seats, ergonomic operating levers, and panoramic windows to achieve 360° no-blind spot visibility
Cab interior noise is controlled below 75dB(A), optional air conditioning and heating system are provided for extreme weather operation

2.4 Durability and low maintenance cost

The boom, arm and undercarriage frame are made of high-strength wear-resistant steel, the bucket is reinforced with hard alloy wear plates to extend service life
All daily maintenance points (engine oil dipstick, fuel filter, air filter, hydraulic oil filling port) are accessible from the ground, which greatly reduces daily maintenance time
Extended service intervals for hydraulic oil (replaced every 5000 hours) and core filters, reducing long-term operating cost

2.5 Strong versatility

Supports quick hitch connection with a wide range of attachments, including hydraulic breakers, augers, grapples, rippers, compaction plates and mulchers, to adapt to different work demands without major modification.

3. Safety and Intelligent Configuration

Equipped with Komatsu Equipment Management Monitoring System (EMMS), which monitors the operating status of the engine, hydraulic system and electrical system in real time, and gives fault alarms in advance to avoid unplanned downtime
Standard safety configurations include travel alarm, swing alarm, emergency stop button, hydraulic lock system to prevent misoperation, and anti-slip steps and handrails for safe access

4. Typical Application Scenarios

Landscaping: Digging planting holes, trenching for irrigation systems, grading and moving landscaping materials
Urban utility maintenance: Trenching for water, electricity, gas and communication pipeline installation and repair, sidewalk reconstruction
Indoor construction: Interior demolition, construction waste removal, basement excavation
Agricultural operation: Digging drainage ditches, farm infrastructure construction, orchard clearing
Small residential construction: Small house foundation digging, backfilling, material handling on narrow job sites

5. After-sales Support

Komatsu provides a global after-sales service network covering more than 150 countries, with supply of genuine spare parts, professional maintenance and technical support. The standard warranty for new PC30 excavators is 1 year / 2000 operating hours, with extended warranty options available for users. The model also has a high resale value in the second-hand construction equipment market.
