Performance improvements and technology with a customer-friendly interface are key benefits of the new F-Series Pavers from Cat® Paving Products.
Fuel Consumption
Several features help improve fuel economy while maintaining high performance levels.
Engine performance is aided by the 167 kW (225 hp) Cat C7.1 ACERT™ engine, which meets European Stage IV and U.S. EPA Tier 4 Final Emissions regulations without sacrificing power. On some F-Series models, a Cat C7.1 engine is also available that meets emissions equivalent to U.S. EPA Tier 3 and E.U. Stage IIIA. It provides power of 186 kW (249 hp).
Eco-mode is standard on F-Series pavers. When used with automatic engine speed control, Eco-mode efficiently manages engine RPMs to optimise fuel economy, reduce sound levels and keep the paver running cool. The control automatically adjusts RPMs when the engine reaches a high-load threshold or needs additional cooling.
Screed Heating System
An integrated generator, the power behind a new screed heating system, is another fuel-saving enhancement. Exclusive to Caterpillar, the F-Series generator was developed by the same team that designed and engineered the highly innovative Cat D7E Dozer.
The integrated generator is directly connected to the paver engine and operates as a core part of the machine. The SE60 Series screeds’ refined heat distribution combine with the generator to bring the screed to the proper temperature in approximately 15 minutes, compared with the previous 30-45.
The F-Series pavers run at about 1,300 rpm while heating, compared with the more common 2,200 rpm of some competitive machines. The lower rpm requirement lessens sound levels and can lead to earlier start times in residential areas.
Technology
Touch screen displays provide increased flexibility for operating and adjusting the machine. The colour display offers high visibility and more user-friendly options.
New feature controls are accessed through the touchscreen. The most frequently used functions are still controlled by switches.
The new single-switch auto-fill feeder system simplifies setup and helps provide consistency for operators of varied experience and skill levels.
The screed-heating system diagnostics enable uninterrupted paving in the event a screed temperature sensor fails. The system automatically compensates, allowing consistent, uninterrupted paving.
Ratio control for the conveyors can now be controlled from the screed. Likewise, the tractor operator can now adjust the mix height for increased flexibility. Previously, only the tractor operator could control conveyor ratio.
A pendant control that enables the screed operator to stand alongside the machine is now available.
Operator Console
The operator console features enhanced functionality.
Controls are as simple and flexible as the contractor needs. Crews who prefer limited options have an organised, efficient control system at their fingertips and mostly in the same locations as on earlier models. Those who want to utilise more functions can do so by accessing various menus through the touchscreens.
Propel and feeder system settings transfer between stations with the touch of a single switch. Speed, as well as operation and travel modes, also are automatically adjusted at both stations.
Paver operators can make various screed adjustments without leaving their seats. Cat Grade Control now can be operated from the tractor consoles if desired.
A single-button auto-feeder system does the work of four switches. An auto-fill button alternates between running the augers and conveyors; helping operators build a proper head of material from the start.
A warm-up/clean-out mode runs the feeder system at a reduced speed, enabling the operator to perform wash-down duties. It also automatically lifts the auger for simplified transport.
If a crew doesn’t want to utilise all controls and the associated technology, “lockouts” are provided on the screed to prevent accidental access.
