2. Key Performance Features

2.1 High Efficiency & Low Fuel Consumption

The SAA6D107E engine delivers high torque at low RPM, ensuring sufficient power output for heavy-load operations such as rock excavation and demolition.
Equipped with Komatsu’s exclusive energy-saving system, including an adjustable ECO mode and automatic idle function, it reduces fuel consumption by 10~15% compared to the previous PC240-7 model, without compromising working efficiency.
The CLSS hydraulic system achieves precise matching between engine output and hydraulic load, minimizing energy loss during compound operations (simultaneous boom lifting, arm operation and swing).

2.2 Ultra-high Durability

The boom, arm and chassis frame are made of high-tensile strength steel, with reinforced welding joints at stress-concentrated positions, resistant to impact and deformation under long-term heavy-load work.
The undercarriage adopts high-manganese steel track shoes, sealed and lubricated track links, and reinforced carrier rollers/ idlers, extending service life by 20% compared to同类 models in harsh working conditions.
The standard bucket uses wear-resistant steel plates and replaceable high-hardness cutting edges, suitable for hard soil, gravel and light rock working conditions.

3. Operator Comfort & Safety

The cab meets global ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) certification standards, providing all-round safety protection for operators.
Pneumatic suspension seat with 6-way adjustment, lumbar support and armrests, effectively reduces vibration during long-term operation.
Low-effort pilot control levers, with adjustable operation sensitivity, reduce operator fatigue.
Fully automatic climate control system with multi-directional air outlets, and sound insulation design keeps internal noise at only 72 dB(A), providing a quiet working environment.
7-inch color LCD monitor displays real-time operating data (fuel level, water temperature, hydraulic oil temperature, fault codes) and active maintenance reminders.
Standard safety configurations include travel alarm, reverse buzzer, hydraulic lock (prevents misoperation of working devices) and emergency steering pump (supports safe parking in case of unexpected engine shutdown).

4. Maintenance & Serviceability

All daily maintenance points (oil filter, fuel filter, hydraulic oil return filter, air filter) are designed to be accessible from ground level, eliminating the need to climb onto the machine for routine service.
Extended service intervals: engine oil change every 500 working hours, hydraulic oil change every 5000 working hours, air filter replacement every 1000 working hours, greatly reducing downtime.
Equipped with Komatsu’s exclusive KOMTRAX remote monitoring system, which supports real-time tracking of equipment location, working hours, fuel consumption and fault warnings, convenient for fleet management and preventive maintenance.

5. Typical Applications

The PC240LC-8 is widely used in:

Municipal engineering: road construction, pipeline excavation, foundation construction
Mining & quarrying: gravel loading, overburden stripping
Water conservancy projects: river dredging, dam construction
Landscaping: terrain shaping, tree pit excavation
Demolition: small building demolition with hydraulic breaker attachment
Material handling: bulk cargo loading in ports and logistics yards

This model also has a very high residual value in the second-hand equipment market, with sufficient spare parts supply and a global after-sales service network, leading to low long-term operating costs.
