Keeps Operators Productive All Shift Long
BENEFITS AND FEATURES
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, air suspension with automatic adjustment to the operator’s weight, lumbar support and a seat heater.
Low Vibration/Sound Levels The rubber-mounted cab includes thick steel tubing. Associated with the comfortable air-suspended seat, it 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 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 areas 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
BENEFITS AND FEATURES
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.
*Not available in all territories like Africa, Middle East and Eurasia. Please contact your Cat dealer for details.
Strength and Versatility on Wheels
BENEFITS AND FEATURES
High Travel Speed (Maximum 37 km/h) Reduces travel time between sites.
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.
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).
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.
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 can be up to 2,000 working hours depending on the machine usage.
Fast Cycle Times, Heavy Lift Capacity
BENEFITS AND FEATURES
Dedicated Swing Pump This closed hydraulic circuit being dedicated to the swing only 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. 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 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.
Maximum Flexibility – High Productivity
BENEFITS AND FEATURES
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.
Boosting Up Productivity
BENEFITS AND FEATURES
SmartBoom* 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.
*Not available in all territories like Africa, Middle East and Eurasia. Please contact your Cat dealer for details.
Ride Control* 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.
*Not available in all territories like Africa, Middle East and Eurasia. Please contact your Cat dealer for details.
