Hydraulic upgrade

摘要

Komatsu is offering a new factory-fitted double auxiliary circuit for its MR-3 mini excavator range. Controlled by a double slider on the machine's PPC joysticks, the new circuit is said to offer higher performances and an improved oil flow.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, is said to be an ideal solution when a rotating function is needed on a roto-tilting attachment or a clamshell bucket, and for demolition equipment.
