Keeps Operators Productive All Shift Long

Comfortable Seat Options

Both standard and comfort seat options give your operators all the comfort they need for a long day of work. The comfort seat is equipped with a passive seat climate control and air suspension which can be adjusted to the operator’s weight, allowing relaxed, ergonomic sitting.

Low Vibration/Sound Levels

The rubber-mounted cab includes thick steel tubing. Associated with the comfortable air-suspended seat helps reduce vibrations and sound levels.

Comfortable Operation

Two-way pedals for travel and auxiliary circuits provide increased floor space, reducing the need to change positions. The auxiliary high-pressure pedal can be locked in the off position and used as a footrest. The steering column is easily tiltable thanks to a large pedal at its base.

Automatic Climate Control

Easy adjustment of the cab temperature with filtered ventilation to make your operators comfortable in all climates.

Storage Compartments

A large compartment behind the seat provides sufficient room to store a large lunch box or a hard hat. A cover secures the contents during machine operation. Several other dedicated spaces can hold large mugs, MP3 players or a cell phone.

Power Supply and MP3 Radio

The cab includes a 12V-7A power supply socket for charging electronic devices such as MP3 players, laptops and cell phones. A CD/MP3 radio is available.

For Ease of Operation

Ergonomic Layout and Smart Controls

The operator station is designed for simplicity, functionality and ease of operation. Frequently used switches are centralized on the right-hand switch console. Features like the heavy lift mode, ride control or SmartBoom will not only increase your productivity but also help reduce fatigue for your operators.

Large Color Monitor

Easy to read and in local language, you can rely on the high-resolution LCD monitor, which will keep you aware of any important information. “Quick Access” buttons allow a quick selection of favorite functions. The tool select function lets you preset up to ten different hydraulic attachments for quick tool changes.

Optimized Visibility

All glass is affixed directly to the cab, eliminating the use of window frames. The 70/30 split front windshield stores the upper portion above the operator and is easy to release. A large skylight provides upward visibility and includes a retractable sunscreen. The parallel wiper system covers the entire front windshield.

Standard Rearview Camera

Together with the best in class visibility to all sides, the rear view displayed on the monitor helps ensure a safe operation.

Strength and Versatility on Wheels

High Travel Speed (Maximum 37 km/h)

Reduces travel time between sites.

Heavy-Duty Axles

Rigidity and long life with effective transmission protection and heavy-duty axles. The transmission is mounted directly on the rear axle for protection and optimum ground clearance. The front axle offers wide oscillating and steering angles.

Smart Travel Alarm (Adjustable)

The alarm sounds when the machine starts moving. The Auto Mode stops the alarm when it has been sounding for an uninterrupted 10-second interval. It can also be disabled (optional).

Stabilizers and Dozer Blade – Versatile Solutions to Do It All.

Various undercarriage configurations are available to provide the best solution for your work environment including dozer blades and/or outriggers. Outriggers can be individually controlled to horizontally stabilize the machine even on slight slopes.

Advanced Disc Brake System

Minimizes the rocking effect when working free on wheels. The disc brake system acts directly on the hub instead of the drive shaft to avoid planetary gear backlash. The axle design lowers life costs. Oil change intervals are at 2,000 working hours.

Joystick Steering

Keep both hands on the joysticks even when simultaneously moving the implements and repositioning the machine, by the use of the slider switch on the right joystick.

Fast Cycle Times, Heavy Lift Capacity

Dedicated Swing Pump

This closed hydraulic circuit maximizes swing performance without reducing power to the other hydraulic functions, resulting in smoother combined movements.

Proportional Auxiliary Hydraulics, Tremendous Versatility

The versatility of the hydraulic system can be expanded to utilize a wide variety of hydraulic work tools using multiple valve options. Basic controls include (optional):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 toolsA hammer line (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.

Maximum Flexibility – High Productivity

Rugged Performance

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


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


Short stick (2000 mm) for maximum breakout force and lifting capabilityMedium stick (2300 mm) for greater crowd force and lift capacity


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* and One-Piece Reach 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.*One-Piece Boom is not available in all markets. Check with your local dealer.

Reduces Stress and Vibration

Rock Scraping

Scraping rock and finishing work is easy and fast. SmartBoom simplifies the task and allows more focus on stick and bucket, while the boom freely goes up and down without using pump flow.

Hammer Work

The front parts automatically follow the hammer while penetrating the rock. Blank shots or excessive force on the hammer are avoided resulting in longer life for the hammer and the machine. Similar advantages with vibratory plate compactors.

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.

Fast Travel Speed with More Comfort

The ride control system lets you travel faster over rough terrain with improved ride quality for the operator. Accumulators are acting as shock absorbers to dampen the front part motion. It can be activated through a button located on the soft switch panel in the cab.
