Komatsu offers twin auxiliary circuits on mini excavators
01 March 2012
Komatsu is now offering customers the option of adding factory-fitted double auxiliary circuits to its MR-3 mini excavators.
The circuits, available on models PC30MR-3, 35, 45 and 55, are controlled by a double slider on the machine's proportional pressure controlled (PPC) joysticks.
One of the additional hydraulic circuits can be used to operate attachments such as tilt buckets or hydraulic breakers, while the second, lower pressure circuit is designed for applications such the rotating function on a roto-tilting attachment, a clamshell bucket, or for demolition tools.
The two circuits can be used independently, with a maximum pressure of 70 l/min on the first line and 25 l/min on the second.
Komatsu said availability of the auxiliary circuits may vary from market to market and advises customers to contact their local Komatsu representative.
