Key Features

1. High-Efficiency Powertrain

Equipped with Komatsu’s self-developed SAA6D107E-1 engine, it adopts electronic high-pressure common rail fuel injection technology and Komatsu exclusive ECOT3 emission control technology, which not only meets strict Tier 3 emission requirements, but also reduces fuel consumption by 8-10% compared with the previous 7-series model. The variable geometry turbocharger (VGT) ensures strong low-speed torque output, with excellent adaptability to heavy load conditions such as rock excavation and heavy material loading. A cold start assist device is standard, supporting normal start at -25°C, and can be upgraded to a cold zone kit for lower temperature environments.

2. Precision Hydraulic System

The PC240LC-8 adopts Komatsu’s patented Closed-center Load Sensing System (CLSS), which adjusts hydraulic flow output according to the actual load of the working device to avoid unnecessary power waste. The built-in PC valve and LS valve realize smooth and accurate compound actions (such as simultaneous digging and lifting, swinging and dumping) without jamming or action lag, greatly improving operation efficiency. The system is preset with multiple working modes:

Power (P) mode: Full power output for heavy-load excavation scenarios
Economy (E) mode: Prioritizes fuel efficiency for light and medium-load daily operations
Breaker mode: Adjusts hydraulic flow and pressure to match hydraulic breakers and other attachment works

3. Safe & Comfortable Operator Cab

The cab meets ROPS (Roll Over Protective Structure) and FOPS (Falling Object Protective Structure) international safety standards, providing all-round safety protection for operators. The fully sealed pressurized cab reduces internal noise to only 72dB(A), and the multi-layer dust filter isolates external dust to maintain a clean internal environment. Other comfort configurations include:

Adjustable air suspension seat with lumbar support, reducing fatigue during long hours of work
Multi-zone automatic air conditioning system, with air outlets distributed around the seat
7-inch color LCD monitor, displaying real-time working parameters, fault codes, fuel consumption and other information
Low-effort pilot control joysticks with adjustable operating sensitivity
On-board radio, USB charging port and storage compartments for personal belongings

4. Outstanding Durability & Reliability

The main frame, boom and arm are made of high-strength thickened steel plate, and all welding joints are subjected to stress relief treatment, which can withstand long-term impact loads under heavy working conditions.
High-manganese steel crawler chains, track shoes and supporting wheels are all designed with dust-proof sealed structures, extending service life by 30% in sandy, muddy and dusty construction sites compared with ordinary models.
The two-stage fuel filtration system effectively filters impurities in low-quality fuel, reducing the risk of engine failure.
The hydraulic system is equipped with a high-precision oil return filter to ensure the cleanliness of hydraulic oil and extend the service life of hydraulic components.

5. Easy Maintenance & Smart Management

All daily maintenance points (air filter, oil filter, fuel filter, hydraulic oil dipstick, etc.) are designed to be accessible at ground level, no need to climb to the top of the machine, shortening maintenance time.
Standard Komatsu KOMTRAX telematics system supports remote monitoring of equipment location, working hours, fuel consumption, fault warning and other data, which is convenient for fleet managers to carry out equipment scheduling, maintenance planning and anti-theft management.
Extended maintenance interval: engine oil replacement interval is 500 hours, hydraulic oil replacement interval is 5000 hours, reducing long-term operating costs.

Typical Applications

The PC240LC-8 adapts to a wide range of working scenarios:

Municipal engineering: Trench excavation, pipeline laying, site leveling, greening construction
Transportation infrastructure: Subgrade excavation, slope trimming, bridge construction, highway and railway construction
Mining and quarrying: Ore stripping, material loading, quarry rock excavation
Demolition work: Equipped with hydraulic breakers or hydraulic shears for small building demolition
Agriculture and forestry: Land reclamation, forest land clearing, water conservancy project construction

Optional Configurations

Users can choose customized configurations according to actual working conditions:

Special buckets: Rock bucket, grid bucket, wide bucket for light materials
Work attachments: Hydraulic breaker, hydraulic shear, wood grapple, ripper, auger
Quick coupler: Realizes fast switching of different attachments within 1 minute, improving work efficiency
Extended boom and arm: Max digging depth can be increased to 9-12m, suitable for deep foundation pit excavation and high-altitude dumping operations
Special environment kits: Cold zone kit (adapt to -40°C low temperature), tropical dust-proof kit (adapt to high temperature and high dust working conditions)
Centralized automatic lubrication system: Regularly lubricates all lubrication points automatically, reducing manual maintenance work

Market Positioning

As one of Komatsu’s best-selling medium-sized excavator models, the PC240LC-8 is widely recognized by global users for its low failure rate, low fuel consumption and high residual value. It is an ideal choice for both individual operators and large engineering fleets, with extremely high cost performance in the 23-27 ton excavator market segment.
