Komatsu, excavator--Komatsu New PC55MR-3 Midi Excavator

Komatsu Europe International has further expanded its MR-3 range of excavators with the launch of the 5.2 t class PC55MR-3 midi excavator. The MR-3 range, built in Italy and covering 1.4 t to 5.5 t models, is now almost complete, with just a 2 t unit to be launched in early 2011.

The new model - which replaces the previous PC50 - has a Stage IIIA engine (28.5 kW Komatsu 4D88E-6), proportional controls, and offers auto-idling as an option. The PC55 has an operating weight of 5280 to 5350 kg, and has a tight tail design making it suitable for working in restricted spaces. It has a bucket capacity 0.07 to 0.175 m3 and is available with either long or short arm, cab or canopy. The CLSS hydraulic system has been further enhanced on this model with new, optional fingertip controls acting on the first auxiliary hydraulic line, offering improved versatility and 'controlability' to guarantee maximum precision with minimum finger fatigue when working with attachments.

The excavator offers unequalled comfort, despite its compact size. Special attention was given to the operator's wellbeing, with ergonomic and dedicated PPC controls, and, as an option, an efficient air conditioning and ventilation system.
