2. Key Features

2.1 High Efficiency & Low Fuel Consumption

Equipped with Komatsu proprietary Closed-Center Load Sensing System (CLSS), the hydraulic system delivers fast response and precise control for smooth compound movements, suitable for fine landscaping and trenching work. The matched ECO mode reduces fuel consumption by up to 10% compared to older generation models, without sacrificing operation performance. The emission aftertreatment system requires no extra diesel exhaust fluid (DEF) and has low maintenance costs.

2.2 Ultra-compact Maneuverability

The PC50 adopts a short-tail swing design, with a minimum tail swing radius of only 1,410 mm. It can operate freely in extremely narrow spaces including urban alleys, indoor demolition sites, orchards and residential construction plots, and can be easily transported via light-duty trucks.

2.3 Operator Comfort

Cab configuration features a fully suspended seat, low-effort joysticks, and a fully sealed air conditioning system, with internal noise controlled at 72 dB(A) to reduce fatigue during long hours of operation.
Canopy configuration comes with a sunshade, safety belt and anti-rollover protection structure (ROPS) to meet safety requirements for outdoor open-air operation.

2.4 Reliability & Easy Maintenance

Boom, arm and chassis structural parts are made of high-strength wear-resistant steel, with reinforced protection for key vulnerable parts, adapting to harsh construction conditions.
All daily maintenance points (air filter, oil filter, fuel filter, hydraulic oil check port) are designed to be accessible from the ground, cutting routine inspection time to less than 5 minutes.
Standard fitted with Komatsu KOMTRAX remote monitoring system, which supports real-time tracking of equipment location, working hours, fuel consumption and fault warning, helping users reduce unscheduled downtime.

2.5 Multi-scenario Adaptability

It supports quick coupler installation, and can be matched with a wide range of attachments to expand functions: hydraulic breaker, log grapple, auger, ripper, sweeper, snow plow, etc., to meet demands of demolition, drilling, material handling, road cleaning and other diversified operations.

3. Typical Application Scenarios

Landscaping: Terrain shaping, irrigation trench digging, tree planting
Urban utility maintenance: Cable/pipeline laying, small road repair, narrow-space demolition
Residential construction: Foundation excavation, site clearing, small material handling
Agricultural operation: Orchard management, farmland renovation, biogas digester excavation
Indoor work: Mall renovation, basement construction, interior demolition

4. After-sales Support

Komatsu provides global unified after-sales service, original spare parts supply, standard warranty policy and operator training support for the PC50 series, making it a cost-effective choice for small construction teams, rental operators and individual users.
