Komatsu PC55MR-3 – specifications

The Komatsu PC55MR-3 is a mini excavator falling into the category of compact earthmoving machinery. As part of the MR series, this model focuses on applications where small dimensions and a minimal swing radius are paramount. The design aims to operate in confined spaces without the upper structure extending beyond the tracks. This enables safe maneuvering in urban areas or on small construction sites where lack of space precludes conventional designs.

Technically, the machine is powered by a Komatsu 4D88E-6 engine with four cylinders, operating at a rated speed of 2,400 rpm. The operating weight of 5,160 kg ensures stable stability during excavation work without exceeding the load capacity of many transport vehicles. With a length of 5,550 mm, a width of 1,960 mm, and a height of 2,550 mm, the unit remains compact enough to pass through standard gates. The climbing ability of 30% allows it to handle slopes and uneven terrain. The fuel tank capacity of 65.1 l ensures sufficient operating time for longer work phases without frequent refueling.

Within the group of mini excavators, the PC55MR-3 positions itself through its specific dimensions and weight. These parameters define the application range for tasks such as laying pipelines, setting paving stones, or excavating foundations in residential areas. The combination of compact design and a weight of 5,160 kg makes it suitable for tasks requiring more stability than lighter models, yet still needing the accessibility of smaller machines.
