AP755 Features High Capacity Cooling System Cat C7 Engine with ACERT Technology Dual Operator Stations Optimum Operator Visibility Electric or LPG Heated Screeds Material Handling System Undercarriage and Steering System Improved Serviceability
Cat C7 Engine with ACERT Technology Gross Power (SAE J1995) 149 kw (202 hp) at 2200 rpm Turbocharged. Meets European EU Stage IIIA engine emission regulations. Maximum fuel efficiency, minimum emissions.
Low-Transverse-mounted Engine Optimum access to the hydraulic pumps. Large service panels ensure quick and easy inspection of the main parts, providing also optimum ground level serviceability.
Hydrostatic Propel System Operational and mechanical benefits. An efficient hydrostatic, closed-loop propel system drives the rubber tracks. Its two pumps are infinitely variable and electronically controlled for starting and stopping ramps. No mechanical linkages.
Operator's Station The dual operator s station includes two seats fitted on a mechanically sliding semi-platforms. Both seats and sliding console are mounted on pivoting pedestals, enhanced visibility for the operator. Excellent view to the: - material in the hopper - steering guides - auger chamber
Operator's Station An optional folding canopy assures operator comfort and protection. Excellent visibility to the steering guide and track contact point. The operator is positioned away from the engine heat and exhaust. Paver operator is visible to Truck Drivers. Benefits include operator comfort and efficiency.
Console Panel Sliding operator s console panel. Fully equipped with comprehensive controls. Conveniently monitor of all machine functions. A lockable vandal cover protects console controls.
Undercarriage and Steering System Two rubber shoe crawlers provide a reliable, smooth ride. The undercarriage provides excellent machine stability. An electronic steering wheel assures a constant speed and direction. Working speed ranges to 26 m/min Travel speed ranges to 6 km/h
Material Handling System The system maintains an uninterrupted flow of material from the hopper to the screed. Feeding conveyors always run full of mix. Immediate delivery of mix to augers. Narrow center flight bar cover helps eliminate segregation.
Feeder & Auger Control Left and right feeder/auger units operate independently of each other. Augers are reversible and hydraulically adjustable in height. Simplified mix delivery. Minimizes hand work. Helps minimize segregation. Benefits include high mat quality and optimum distribution of material in front of the screed.
Electrical System 24-volt electrical system. Two 12-volt batteries. 24-volt, 80-amp alternator. Cat enhanced-life electrical standards increase reliability and are easy to troubleshoot and maintain.
Serviceability Excellent access to all machine parts requiring regularlyscheduled maintenance. The front service panel features a single wide hinged door providing easy filter and traction valves serviceability.
Serviceability The ergonomic operator s station provides optimum comfort, visibility and control during machine operations. Hydraulic motors for augers are fitted outboard for improved accessibility and serviceability.
Serviceability Motors for conveyors are fitted under the side doors promoting easy access for servicing. Wiring for the electrical system is numbered and labeled with component identifiers to simplify troubleshooting.
Tractor Options Folding operator s station canopy. Hydraulic raising operator s station canopy. Grade control systems. Slope control systems. Supplementary working lights package. Automatic greasing system for tractor. Refueling pump.
