2. Key Performance Features

2.1 Engine & Fuel Efficiency

Equipped with Komatsu's proprietary ECOT3 technology, combined with high-pressure common rail fuel injection system and exhaust gas recirculation (EGR) system, it reduces harmful emissions while cutting fuel consumption by 10~15% compared with the previous generation PC240-7 model.
Two working modes are available for users to switch: Power (P) mode for heavy-load high-efficiency operations, and Economy (E) mode for light-load scenarios to further reduce fuel cost.
Auto idle and auto deceleration functions are standard: the engine automatically reduces rpm when there is no operation for 4 seconds, effectively saving fuel.

2.2 Hydraulic System

Adopts Komatsu's exclusive Closed-center Load Sensing System (CLSS) with variable displacement piston pumps, which delivers fast response and high precision of movements. It ensures stable speed and force for each actuator even when multiple actions (boom lifting, arm pulling, bucket rotating, swinging) are performed at the same time.
Built-in pressure compensation valves reduce unnecessary pressure loss, and the hydraulic oil replacement interval is extended to 5000 hours, greatly lowering long-term maintenance costs.

2.3 Operator Cabin & Safety

The fully sealed, sound-insulated cabin has an internal noise level as low as 70 dB(A), providing a quiet working environment.
Standard ROPS/FOPS certified cabin structure protects operators from collision and falling object impacts.
Equipped with fully adjustable air-suspension seat, multi-vent automatic air conditioning system, and a large full-color LCD monitor that displays real-time data including fuel consumption, oil temperature, fault codes, and maintenance reminders.
Optional rearview camera, extra working lights, and anti-theft system are available to adapt to complex working conditions.

2.4 Durability & Easy Maintenance

The boom, arm, and bucket are made of high-strength wear-resistant steel plate, with reinforced welding points, which can adapt to long-term heavy-load operations such as rock excavation.
The heavy-duty undercarriage adopts sealed lubricated track links, supporting rollers and idlers, with a service life 30% longer than similar products of other brands.
All routine maintenance points (fuel filter, oil filter, air filter, grease filling ports) are designed to be accessible from the ground, no need to climb onto the upper frame for maintenance.
Standard Komatsu KOMTRAX remote monitoring system: fleet managers can check equipment location, working hours, fuel consumption, and fault warnings in real time via mobile app or web platform, which reduces unplanned downtime and prevents equipment theft.

3. Typical Applications

Municipal engineering: road construction, pipeline trenching, urban greening land preparation
Building construction: foundation excavation, construction material loading and unloading, site clearing
Small & medium mining: overburden stripping, ore handling, quarry excavation
Special operations: can be equipped with breakers, grapples, hydraulic shears for demolition, forestry logging, and scrap handling work.

4. Optional Configurations

Different bucket types: rock bucket, grid bucket, light-duty earthwork bucket
Work attachments: hydraulic breaker, wood grapple, quick coupler, hydraulic shear
Undercarriage options: wide track (for soft/wet ground), heavy-duty track shoe
Comfort upgrades: premium audio system, heated seat, 360° surround view camera

5. Market Advantages

As one of Komatsu's best-selling medium excavator models, the PC240LC-8 has a very high global ownership, with easily accessible spare parts and a perfect after-sales service network. It also has an excellent resale value, with a 3-year old equipment residual rate remaining above 60% in most markets, making it a cost-effective choice for both individual operators and large construction fleets.
