Komatsu PC40-5 3.91t 1988-1995 - Product Description

Powertrain and Design

The Komatsu PC40-5 is powered by a Komatsu 3D95S diesel engine, generating 28.7 kW. This three-cylinder, four-cycle engine is water-cooled and operates optimally at 2600 rpm. The low noise level inside the operator's cab helps minimize fatigue, thanks to the noise-absorbing materials used in its construction.

Undercarriage and Hydraulics

The excavator features a fully hydraulic drive system, with each track driven by an axial piston motor. It produces a maximum breakout force of 25.5 kN, allowing for efficient operation in confined spaces. Additionally, the boom can swing 90° left and right, enhancing the machine's versatility in challenging environments.

Operating Parameters

This model has an operating weight of 3910 kg and a bucket capacity of 0.19 m³. It measures 5.34 m in transport length and 1.84 m in width. The maximum digging height reaches 3.50 m, while the maximum horizontal reach is 5.45 m. These dimensions make the PC40-5 convenient for transportation and effective for excavation tasks.

Optional Equipment

The PC40-5 can be fitted with an optional cab, offering better protection from external elements. Various bucket attachments are also available, tailored to meet job-specific requirements. The standard features include a 12V electric starting motor and a 35 A alternator to ensure efficient operation.

Safety and Technical Data

The PC40-5 adheres to safety standards, providing stability when operating on uneven terrain. The cab can be equipped with different protection systems, and hydraulic controls include safety features to prevent unintended movements. Furthermore, the exhaust system and high-quality materials used in its construction ensure long-lasting performance and reliability.
