The AP655F is a mid to high production, rubber track paver that excels on airports runways, interstates, highways, and other large jobsites. It's high travel speed, flotation, and traction deliver superb mobility.
The C4.4 engine provides 129 kW (173 hp) and meets U.S. EPA Tier 4 Final and EU Stage IV emission standards.
Eco-mode utilizes an engine speed of 1650 rpm and reduces fuel burn by up to 5% over Cat E-series pavers while also lowering sound levels even more.
Automatic Engine Speed Control
When automatic engine speed control is activated, the engine speed is reduced to an idle speed of 1000 rpm when the propel lever is moved to neutral, or to 1300 rpm when screed heat is active.
Eco-mode and automatic engine speed control when activated together modify the engine rpm based on load factors. When activated the engine will operate at 1650 rpm when paving. If the upper power threshold is exceeded, the engine speed will increase to 2200 rpm and remain there until the demand drops below the threshold and remains there for 30 seconds, ensuring reliable performance.
Quiet heat mode operates at an engine speed of 1300 rpm and provides screed plate heating in under 15 minutes.
Quick heating mode provides a heat-up time in under 35 minutes when equipped with the wide-width paving package. Quick heat does not heat any faster than quiet heat when the screed is at standard extendable widths.
Three preset heating options provide a wide range of temperatures for various mix designs; Low is 110 degrees C or 230 degrees F, medium is 130 degrees C or 266 degrees F, high is 160 degrees C or 320 degrees F.
The dual independent operating stations can extend beyond the frame for good all-around visibility. The low profile, front-mounted cooling system improves forward viewing and the redesigned auger assembly optimizes visibility to material height in front of the screed. The heated seat option, multiple seat adjustments, and tilting consoles conform to the operator to provide day-long comfort. The top-mounted cooling system directs fumes, hot air, and fan noise away from the crew for a cooler and quieter working environment.
The exclusive ventilation system draws fumes from the conveyor tunnel as well as the auger chamber and redirects them away from the operator for a more comfortable working environment.
Single touch features for the auto-fill feeder system, feeder system activation, and hopper control, allow operators to concentrate on truck exchanges and other duties for improved efficiency.
Technology helps operators perform. Intuitive symbols and large graphics simplify operation, while the interactive LCD display with touchscreen access to generator activation, screed temperature control, and mix height adjustment, increase efficiency.
The auto fill feeder system simplifies starts by alternating the conveyors and augers until the mix height reaches the sensor set point, eliminating manual activation and constant monitoring.
Single Touch Feeder System
The two augers and two conveyors can be activated automatically with a single switch, simplifying setup. Each auger and each conveyor can still be operated independently when needed.
One Touch Hopper Control
The hopper wings and hydraulic apron can be folded with a single touch and release. The system can be tailored to activate left or right wings, or the front hydraulic apron independently or together.
Cleanout and Warm-Up Mode
This feature activates the augers, conveyors, and tamper-bar (if equipped) at a reduced speed, allowing the application of release agents to prevent material build-up.
Mix Height Adjustment
Mix height adjustment in front of the screed can be modified from the tractor LCD display for increased versatility when needed.
Hydraulic Mainframe Extensions
The optional 457 mm (18") hydraulic mainframe extensions attach to the auger assembly and provide smooth material flow out to the extenders. They retract with the screed extensions when reducing paving widths.
Multiple Feed Sensor Options
The feeder system can be tailored to automatically operate with 0, 2, or 4 feeder sensors. When paving with 0 sensors due to a failure, simply set the feeder system to automatic and adjust the mix height setting, no need to cycle the manual switch as previous models required.
Hardware-free bed plates simplifies replacement and bottom side mounting hardware for the chain guards eliminates bolt wear and material build-up for easier service.
The Mobil-Trac undercarriage minimizes tow-point movement. The front and rear bogie sets crawl over obstacles and help maintain ground contact. The smooth belt option performs well on soft base materials and fresh mats. The tread-bar design excels on loose paving/transport conditions.
Self-tensioning accumulators, center guide blocks, and rugged internal belt cables ensure durability. The components are rubber coated in order to shed asphalt and prevent accumulation.
Exclusive zone monitoring allows heating to continue in the event of a temperature sensor failure. The system also monitors heating elements for failure conditions, eliminating unnecessary replacement.
Feeder system ratio adjustment capability from the screed provides versatility. Standard power adjustment for extender height, slope, and crown, allows for on-the-go adjustment at standard and maximum paving widths.
Two-Speed Proportional Extender Control
Exclusive two-speed proportional extender control offers slower speed for precise control around obstacles and quick reaction when extending paving widths.
The heating elements slide out for easy replacement, no need to remove the screed plates. Machined screed frames simplify plate replacement and leveling.
Tamper Bar Screed Option
Tamper bar equipped screeds increase density as it tucks material under the screed plates. Three stroke settings of 2, 4, and 7 mm and the variable tamper speed of 700 to 1800 rpm provide versatility.
Wide-Width Paving Packages
Exclusive power controls simplify adjustment across the entire paving width for better mat texture and quality. An innovative design utilizes extender slope to attach wide-width paving packages, eliminating the need for other lifting devices.
F-Series pavers allow Cat Grade Control to be operated from any of the two tractor or two screed consoles. Split screen mode can be setup to monitor each side of the screed enabling single person operation.
More accurate control maximizes mix utilization and saves money. True averaging with sonic sensors that utilize 5 transducers, 2 readings are discarded and 3 averaged. A 10-point Auto-Calibration eliminates over/under adjustment from a single calibration point. Cross-coupling, slope and elevation are maintained with height adjustments. The true 9 m (30 ft) sonic averaging beam modifies tow point movement by 1/3 of total grade deviation.
Water-resistant displays, factory installed components, and consistent routing deliver performance. Sealed components withstand heat, moisture, and vibration, while the built-in temperature sensors provide better reliability than bail-type sensors.
