Caterpillar has launched its new F series excavators, saying they give the operator an unprecedented level of accuracy for far less effort.
We had the opportunity to take a look at the new range at Cat distributor William Adams’ lot in Clayton, Victoria, today. Cat also took the opportunity to launch its M series wheel loaders.
The F series consists of 15 models, ranging from the 11-tonne 311FL RR to the 92-tonne 390FL. All models are powered by proprietary Cat diesel engines configured to meet US Tier 4 Final/EU Stage 4 emissions standards.
The engines have an automated speed control system that adjusts engine speed based on load, an automatic shutdown after a pre-set idle time plus multiple work modes that adjust the machine to specific tasks. Cat says these systems combine to reduce fuel use by up to 10 percent over previous models.
The F series machines can also be equipped with Cat’s GRADE automated grading system. Using this, operators merely have to set the maximum depth, height and bucket angle they wish to dig at and the excavator won’t move beyond these parameters.
Cat says this system can deliver accurate grades up to 45 percent faster than manual grading methods.
The structure of the Cat F series excavators is manufactured with reinforced mountings to accommodate the heavy-duty ROPS operator’s cab. The boom arm and sticks have baffle plates for added strength and is further reinforced by the machine’s box-section design.
The operator’s cab has been redesigned from previous models and includes a heated/cooled air-suspension seat, air-conditioning using filtered air, and the right and left joystick controls are adjustable to suit operator preference.
For safety and convenience Caterpillar has placed most routine service points at ground level behind large doors that latch securely in place. A full-length firewall separates the pump compartment from the engine compartment to isolate fires if they happen. There is also a ground-level fuel shutoff switch that can immediately stop the engine in an emergency.
