حفارة صغيرة Komatsu PC30

As a globally renowned construction machinery brand, Komatsu excavators, leveraging technological expertise and market experience, offer significant advantages in performance, reliability, and economy. They are suitable for a wide range of applications, including earthmoving, mining, municipal construction, and agricultural development. Their core advantages can be summarized in the following six points:
1. Strong compatibility between the power and hydraulic systems, resulting in high operating efficiency

Independent powertrain and stable power output

Komatsu excavators are equipped with independently developed diesel engines (such as the 3D series for miniature excavators and the SAA series for large excavators). These engines, along with core components such as hydraulic pumps and transmissions, are all factory-matched, resulting in low power transmission losses (5%-8% lower than comparable third-party assembled equipment). For example, the PC360LC-11 large excavator boasts a net engine power of 203kW, exhibits no noticeable speed loss even under heavy loads, and boasts an earthmoving cycle time (excavation - lifting - dumping) that is 10%-15% faster than competing excavators. Precise and controllable hydraulic system.
The load-sensing hydraulic system automatically adjusts hydraulic flow based on workload intensity: reduced flow saves fuel during light-load operations (such as site leveling), while increased flow boost is achieved during heavy-load operations (such as hard rock excavation). Joystick response delay is ≤ 0.3 seconds, enabling precise bucket angle control during delicate tasks (such as pipe docking and slope shaping), reducing rework.

Durable structure, low failure rate, and long service life.
High-strength structural components offer excellent fatigue resistance.
Key components such as the bucket, arm, and boom are constructed from high-strength, wear-resistant steel (such as Komatsu's specialized HT800 steel), which is 15%-20% thicker than ordinary steel. Key welds feature a "double-layer weld + stress relief" treatment for superior deformation resistance. For example, the PC7000-8 bucket used in mining applications boasts a lifespan of 8,000-10,000 hours (compared to approximately 6,000-7,000 hours for comparable competitors). Excellent compatibility of wearing parts and low wear rates. Bucket teeth, liners, and other wearing parts are made of high-chromium alloy with a hardness exceeding HRC60. When handling materials like sand, gravel, and limestone, they wear 30% slower than standard parts. Furthermore, standard specifications allow for universal use across excavator models (for example, bucket teeth for small excavators are compatible with the PC20-PC50 series), reducing spare parts inventory costs.

III. Outstanding fuel economy and low operating costs. Intelligent fuel-saving technology controls fuel consumption. The standard "ECO mode" reduces engine idle speed (approximately 800 rpm for small excavators and 700 rpm for large excavators) and optimizes hydraulic flow distribution, resulting in overall fuel consumption 10%-15% lower than in standard mode. For example, the mid-sized PC200-11 machine consumes approximately 18-20L/h of fuel during earthmoving operations, compared to approximately 22-25L/h for similarly sized competitors. This translates to fuel savings of 16,000-20,000 yuan (based on diesel fuel costing 8 yuan/L) for 2,000 hours of operation per year.

Long maintenance intervals and low maintenance costs

Engine oil change intervals are 500 hours (1,000 hours for some large machines), and hydraulic oil change intervals are 2,000 hours, 30%-50% longer than the industry average. Furthermore, centralized maintenance points (such as the oil and air filters, which are located on the side of the machine) eliminate the need to disassemble complex components. Basic maintenance can be completed by a single operator in 30 minutes, minimizing downtime. 4. High operating comfort and reduced operator fatigue.

Humanized cab design.

The cab features a suspended shock-absorbing structure that filters over 60% of ground vibrations. The seat is a multi-adjustable hydraulic seat (supporting fore/aft, height, and backrest angle adjustments) and equipped with a lumbar support, preventing back pain during extended work (over 8 hours). The cab is well-sealed and operates with a noise level of ≤75 decibels (compared to approximately 80-85 decibels for comparable competitors), minimizing noise interference.

The intuitive operating interface makes it easy for novices to use.

The instrument panel uses a color LCD display, displaying real-time information such as fuel consumption, engine load, and fault codes, allowing users to easily determine equipment status without requiring specialized knowledge.

The joystick features a light lever (40% less effort than traditional mechanical levers) and a short travel, allowing precise control of movement during delicate operations and reducing operational difficulty. 5. Wide Application Adaptability and Versatile Expandability
A comprehensive range of machines accommodates diverse working conditions. From small models (PC10-PC50, suitable for interior decoration and garden renovation), mid-size models (PC120-PC360, suitable for municipal construction and earthmoving), to large models (PC400-PC8000, suitable for mine stripping and large-scale infrastructure projects), these machines can meet the needs of various operation scales. Some models feature adjustable track widths (such as the PC30MR-5, which can be retracted from 1.3m to 1.1m), making it suitable for confined spaces.
Multiple Attachment Compatibility: One Machine for Multiple Uses
Over 20 attachments, including buckets, breakers, wood grapples, and rippers, can be quickly replaced. A breaker handles concrete blocks and rocks; a wood grapple is suitable for landscaping (grabbing trees); and a tilting bucket is used for slope grading, eliminating the need for additional specialized equipment and improving equipment utilization. 6. Comprehensive global service network and fast after-sales response.

Timely spare parts supply.

Komatsu has over 2,000 spare parts centers worldwide, with regional spare parts depots in major Chinese cities (such as Beijing, Shanghai, and Guangzhou). Common spare parts (such as bucket teeth, filters, and hydraulic oil) can be delivered the same or next day, eliminating extended downtime due to parts shortages.

Professional technical support.

Equipped with a "remote diagnostic system" (select newer models), this system monitors equipment status in real time via a mobile app, providing early warning of faults (such as high hydraulic oil temperature and filter clogs). Our after-sales engineers are factory-trained and have over five years of repair experience. Complex faults (such as abnormal engine noise and hydraulic system leaks) can be addressed on-site within 24 hours.
