EFFICIENCY
The high-definition hydraulic system provides load sensing and flow distribution, which ensures accurate operation, efficient operation and greater controllability. Power on Demand delivers optimum efficiency and performance the moment you need it. This automatic system provides fuel efficiency through an appropriate engine rating to meet all operational needs as needed.
FLEXIBILITY
With a wide range of Cat working tools, the Cat mini excavator is a versatile machine that can meet the demands of any work site. Turning the bucket 200 degrees provides greater material retention during loading and makes it easier to dig flat walls without having to relocate the machine.
SPECTACLE
The orientation of the front excavator bucket allows the operator to perform work faster. The COMPASS control panel is a standard feature that allows the operator to easily adjust auxiliary flows to achieve optimal performance of the working tool, activate automatic idle mode to improve fuel efficiency, and use the safety system to protect valuable assets by simply pressing a button. The site monitoring system included in the COMPASS monitor provides an output signal from the pitch and roll sensors to aid in leveling and level ground. This affects the accuracy and performance at the end of the work.
PERFORMANCE
Convenient maintenance and service requirements include easy access to daily checkpoints, 500-hour engine oil and filter change, 500-hour front implement lubrication interval, S · O · SSM oil sampling valve and overall durability.
SECURITY
All Cat mini excavators with a load capacity from 3.5 to 8 tons are ROPS, TOPS and Top Guard Level 1 certified and include a Cat interlock system (hydraulic interlock), a certified battery that allows you to relieve auxiliary pressure, providing connectivity and disconnection . Tools safer and easier as well as an alarm. All of these safety features are standard on the E2 model range (optional signaling in Europe).
