Upgraded midi excavator offered by Komatsu
An important midi excavator is offered by Komatsu
An array of performance improvements ensure that Komatsu’s 5.3tonne class PC55MR-3 midi excavator offers increased performance over earlier generation machines. Weights range from 5.28- 5.35tonnes depending on specification and the PC55MR-3 features a tight tail design that allows the machine to work in restricted spaces. Power comes from a Komatsu 4D88E-6 diesel that meets the necessary emission standards. High operator comfort is claimed due to ergonomic controls and the machine also offers good visibility from its low noise cab. The machine is available with either long or short arm, cab or canopy, rubber, steel or road liner shoes to suit the application. High efficiency is claimed due to the use of the Komatsu CLSS hydraulic system, which also provides precise control even in combined operations.
As an option Komatsu offers a factory-fitted double auxiliary circuit, which can be controlled by a double slider on the machine’s PPC joysticks. This offers higher performance and improved oil flow. By switching into the attachment work mode, the double circuit offers a range of working options. One additional hydraulic circuit can be used to operate attachments such as tilt buckets or hydraulic breakers. The second hydraulic line, with a lower oil flow rate, suits use with a roto-tilting attachment or a clamshell bucket, and for demolition equipment.
Maintenance is said to be easy and the machine also features the firm’s sophisticated KOMTRAX satellite monitoring system, which can deliver machine data over the internet and allows owners or fleet managers to view the machines location, performance and service requirements.
