Hydraulics

The Multi-Combined Valve allows the operator to select up to ten preset work tools from the monitor.
A medium pressure function providing proportional flow, ideal for tilting buckets or rotating tools
A hammer circuit (one-way high pressure)
A dedicated circuit to operate hydraulic quick couplers.

Heavy Lift Mode - Maximizes your lifting performance by boosting the lifting capacity of the machine up to 7%.

Adjustable Swing Aggressiveness - Allows you to adjust the aggressiveness of the machine swing to match the operator's preferences.

Stick Regeneration Circuit - Increases efficiency and helps enhance controllability for higher productivity.

Booms and Sticks

Rugged Performance - Booms and sticks are welded, box section structures with thick, multiplate fabrications in high stress areas for the tough work you do.

Flexibility - The choice of various booms and sticks provides the right balance of reach and digging forces for all applications.

Sticks -

Medium stick (2500 mm) for greater crowd force and lift capacity
Long stick (2800 mm) for greater depth and reach

Booms -

Variable Adjustable (VA) – improved right side visibility and roading balance. When working in tight quarters or lifting heavy loads, the VA boom offers the best flexibility.
One-Piece Boom – Fits best for all standard applications such as truck loading and digging. A unique straight section in the curve of the side plate reduces stress flow and helps increase boom life.

Smart Technologies

SmartBoom* - Reduces stress and vibration.

Truck Loading - Loading trucks from a bench is more productive and fuel efficient as the return cycle is reduced while the boom down function does not require pump flow.
