The Cat C4.4 engine achieves emission levels equivalent to U.S. Environmental Protection Agency (EPA) Tier 3, EU Stage IIIA, Korean Tier 3 and China Stage 2 emission standards, while offering increased performance, high fuel efficiency and reliability. This means more work done in a day, low operating cost and minimal impact on our environment.
Low sound levels, as a result of the variable fan speed and remote cooling system.
Product Link allows remote monitoring of the machine and helps improve your fleet efficiency as well as reduce your costs. Your Cat dealer can help extend service intervals, meaning fewer required fluids and disposals, all adding up to lower operating costs.
Lubricant filters and various drains are designed to minimize spills. Cat O-Ring Face Seals, XT™ Hoses and cylinders help prevent leaks that can reduce performance and cause harm to the environment.
This program is a key element in the range of solutions offered by Caterpillar and Cat dealers throughout the world to help customers achieve growth at the lowest cost while eliminating waste. Used equipment is inspected, guaranteed and ready for work and customers will benefit from a Caterpillar warranty.
Responding quickly to changing loads, the constant power strategy delivers the same amount of power regardless of operating conditions. The Cat engine achieves emission levels equivalent to U.S. Environmental Protection Agency (EPA) Tier 3, EU Stage IIIA, Korean Tier 3 and China Stage 2 emission standards, delivers a maximum net power (Acc. ISO 14396) of 108 kW at a rated speed of 2,000 rpm.
This combination provides outstandingly low fuel consumption during both working and traveling applications.
The electronically controlled hydraulic motor drives a variable speed on-demand fan, resulting in optimized fuel consumption.
The Automatic Engine Speed Control reduces engine speed if no operation is performed, reducing fuel consumption and sound levels.
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.
The rubber-mounted cab includes thick steel tubing. Associated with the comfortable air-suspended seat, it helps reduce vibrations and sound levels.
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.
Easy adjustment of the cab temperature with filtered ventilation to make your operators comfortable in all climates.
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.
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.
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.
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.
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.
Together with the best in class visibility to all sides, the rear view displayed on the monitor helps ensure a safe operation.
Reduces travel time between sites.
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.
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).
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.
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.
This closed hydraulic circuit maximizes swing performance without reducing power to the other hydraulic functions, resulting in smoother combined movements.
Maximizes your lifting performance by boosting the lifting capacity of the machine up to 7%.
Allows you to adjust the aggressiveness of the machine swing to match the operator's preferences.
Increases efficiency and helps enhance controllability for higher productivity.
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.
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.
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.
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.
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.
Cat Work Tools are designed to function as an integral part of your excavator and are performance-matched to Cat machines.
Hydraulic quick couplers enable to simply release one attachment and connect to another without the need to leave the cab, making your excavator highly versatile and productive. Spindle quick couplers are also available.
A wide range of specialized buckets including the Cat K Series™ or J type (depending on the region) Ground Engaging Tools is available to match all application requirements.
Cat hammer series deliver very high blow rates, increasing the productivity of your tool carriers in demolition and construction applications.
The Multi-Grapple with unlimited left and right rotation is the ideal tool for stripping, sorting, handling and loading. The powerful closing force of the grab shells combined with fast opening/closing time ensures rapid cycle time, which translates to more tons per hour.
Cat compactors integrate perfectly with the Cat hammer line - brackets and hydraulic kits are fully interchangeable between hammers and compactors.
Perform tool changes in seconds … Combine a quick coupler with common work tools that can be shared between the same size machines and you'll get flexibility on every job. The hydraulic quick coupler automates tool exchange, so operators can change work tools quickly, from the safety and comfort of their cabs. Make your operators more efficient and productive.
With timely, useful information, you can better manage your assets and costs. Just a few clicks give you access to comprehensive remote monitoring, asset tracking and maintenance management. The powerful, web-based VisionLink® application allows you to see information from all your assets - working time vs. idle time, fuel usage, diagnostic fault codes, security alerts and more. When you know where your equipment is, what it's doing and how it's performing, you can maximize your efficiency and lower your operating costs. It pays to know Cat Product Link.
