Komatsu PF55L 21.2t 1988-1995 - Product Description

Powertrain and Design

The Komatsu PF55L is a crawler excavator with an operating weight of 21.2 tons. It features a KOMATSU S6D105 diesel engine providing an output of 88.3 kW at 2100 RPM. The machine employs hydraulic drive, allowing it to perform various construction tasks effectively. Its flexible design makes it an ideal choice for work in confined spaces and challenging terrain conditions.

Undercarriage and Hydraulics

The PF55L is equipped with a fully hydrostatic undercarriage that ensures excellent maneuverability. It has variable-capacity hydraulic pumps, optimized for delivering power for all working operations. The high-quality hydraulic system allows the machine to execute complex tasks with great precision. An automatic control system, featuring a built-in microcomputer, maintains optimal arm and bucket angles, thereby increasing work efficiency.

Operating Parameters

Operating parameters of the Komatsu PF55L include a maximum digging height of 9230 mm and a maximum digging depth of 6550 mm. The maximum reach is 9850 mm, and its bucket capacity is 0.8 m³. The bucket width is 665 mm, clearly illustrating this model’s capabilities. The machine is designed to expedite work at greater depths and heights thanks to its flexible boom.

Optional Equipment

The PF55L does not come with any additional equipment such as a particulate filter or air conditioning. There are no additional options listed in the available data. The machine is designed to achieve maximum efficiency with its basic equipment. Therefore, consideration should be given to the potential for purchasing or exchanging components based on specific work requirements.

Safety and Technical Data

The PF55L model complies with safety standards associated with construction work. It is equipped with hydraulic brakes and a hydraulic lock, safeguarding against unexpected machine movement. Additionally, its low ground pressure of 0.36 kN/cm² minimizes the risk of soil erosion at the construction site. In terms of servicing, all replacements and adjustments can be performed while maintaining high quality standards.
