Mackolines Machines & Hire builds the first model for cable logging operations.
The new Mackolines Machines & Hire 180 swing yarder is purpose-built from the ground up. It combines the speed and stability of conventional yarders with the mobility and simpler controls of excavator-based yarders. The result is a powerful and versatile yarding machine for extreme terrain logging applications. The 305 kW (409 hp) carrier was carefully designed with a component layout, hydraulic system, drivetrain, and boom system optimized for yarding. The result is high line pull, excellent stability, and efficient operation.
Designed to achieve exceptional stability, The 180 can achieve high line pull without the use of guylines in most operating conditions. The purpose-built undercarriage has a reinforced pedestal and carbody with an extended blade for added stability. The blade mounts are tied directly into the carbody for added strength. The machine can be quickly moved to the next set-up by simply lifting the blade. In operating situations where additional stability is required such as with extremely long yarding distances or low deflection conditions, a simple static guyline can be quickly set up. The machine still retains the ability to swing with this guyline attached.
The purpose-built winches are driven with efficient dedicated closed loop hydraulic circuits for smooth operations and infinitely variable speed control. The closed loop circuits provide energy when lowering the load for increased efficiency. Intuitive joystick controls, along with many programmable features reduce operator training time and increase production.
