The AP-1050B is a high-production machine designed for interstates, highways, subdivisions, airports and other similar sized projects. It is also effective on new construction projects because of its track undercarriage. The steel track undercarriage uses field-proven Cat D3 Track-type Tractor technology. This method of propulsion offers advantages when operating on unstable bases or on steep grades. Excellent tractive effort, low ground pressure and enhanced flotation are some of the advantages. The new model is suited to all geographic regions that favor track pavers. Typical characteristics of these areas include sandy, loose soil; sub-base or base materials that do not permit good traction by wheel pavers; and areas with significant grades.

Turbocharged for Top Performance and Efficiency
The Caterpillar 3116TA diesel engine is turbocharged for top performance and efficiency especially at high altitudes.

Transverse Engine Mounting
Transverse engine mounting provides better cooling performance and greater accessibility for service.

Low Sound Emission
Low sound emission achieves compliance with major regulatory rules according to Caterpillar sound pad test results.

Heavy Duty Unit-type Fuel Injection
The heavy duty unit-type fuel injection and low pressure fuel lines minimize opportunity for fuel leaks.

Intake Manifold Heater
The intake manifold heater preheats incoming air for quick cold weather starting.

The Caterpillar 3116TA diesel engine meets EPA/CARB emissions engine regulations.

Hydrostatic Drive System
Efficient hydraulic drive system eliminates chains and other mechanical linkages between diesel engine and final drive components.

Closed-loop Hydrostatic Propel System
The closed-loop hydrostatic propel system provides efficient, low-maintenance operation.

Speed Control System
The speed control system maintains preset paving speeds throughout a job.

Propulsion Controller
The propulsion controller provides accurate control of steering and propulsion systems.

Decel Pedal
The decel pedal provides foot control of propel speed freeing the operator to control other paving functions.

Dual Path Steering System
The dual path steering system utilizes steering wheel for simplified operation.

Operator's Station
Single operator's station designed for comfort and optimum efficiency.

Single Operator's Station Slides from Side to Side
The single operator's station slides from side to side and includes fully equipped instrument console and steering wheel with lockable cover.

Dual-slide Feature
The dual-slide feature allows the seat to be slide from side to side and front to back on the pedestal frame, enhancing visibility.

Operator's Seat
The operator's seat pivots 152 mm (6") to the left or right to further enhance operator visibility.

Low-mounted Engine
The low-mounted engine provides unobstructed forward visibility.

Control Console
Full instrumentation package keeps operator informed of all major systems status.

International Symbols and Functional Word Descriptions
The control console has international symbols and functional word descriptions for all controls.

Gauges are Analog Type
The gauges on the control console are analog type for quick interpretation.

Warning Lights and Horn Alert
Warning lights illuminate and horn alert operator to: 1) High hydraulic oil temperature; 2) Low hydraulic oil level; 3) Low engine oil pressure; or 4) High engine coolant temperature.

Electrical Wiring
The electrical wiring is protected by an articulated vinyl enclosure.

Speed Control
Speed control allows the operator to dial a maximum paving speed. Once set, the paver returns to the preset speed when the propel lever is in full forward position.

Feeder/Auger Control System
The feeder/auger control system gives precise mix delivery through the most advanced material handling system.

Feeders and Augers
Left and right feeders and left and right augers are all controlled independently, eliminating the need for feeder gates.

Feeder Speeds
Once the feeder speeds are set, the ratio of feeder speed to the maximum auger speed is automatically maintained by the material handling controller, regardless of propel rate or paving widths.

Controlled Mix Delivery
To control mix delivery, the operator sets a speed rate for each feeder and will maintain the desired mix level in the left and right auger chambers.

Component Wear Reduced
Component wear is reduced because full feeders run at slower speeds.

Potential for Mix Segregation Minimized
The potential for mix segregation is minimized because the head of material remains constant.

Gateless Feeders
Slower running feeders reduce wear and segregation.

Gateless Feeders Always Run Full
The gateless feeders always run full of mix regardless of the speed required to fill the auger chamber.

Changes in Feeder Speed
When changes in feeder speed are needed, delivery of mix to the augers is immediate.

Drag Pans
The drag pans are constructed with abrasion resistant, heat treated steel.

Feeder Flight Bars
The feeder flight bars are forged steel and pinned to two strands of roller bushed chain.

Potential for Segregation Reduced
The potential for segregation is reduced with slower running feeders, especially when working with large stone mixes.

Auger Assembly
The adjustable height auger assembly promotes mat consistency and minimizes segregation.

Hydraulically Adjusted
The auger assembly can be hydraulically adjusted 142 mm (5.6")

Minimizes Segregation
When working with larger stone mixes, segregation can often be eliminated or minimized by raising the augers to allow mix to flow unrestricted under the auger assembly.

The ability to raise the auger assembly simplifies loading and unloading from a transport vehicle.

Dual Lift Cylinders
The dual lift cylinders provide a stable position for the augers, enhancing mat quality.

Feeder Design Improves Mix Flow
The feeder design improves mix flow using a tunnel construction that helps minimize segregation.

Distance Between Feeders Reduced
The distance between the two feeders is significantly reduced because the auger drive assembly is not part of the tractor.

Narrow Distance Between Feeders
The narrow distance between feeders allows flow from both feeders to blend together easily as they discharge into the auger cavity. This design helps minimize segregation.

Auger Case
Since the auger case is not attached to the tractor, voids under the chain case are eliminated.

The track system of the AP-1050B is designed for superior ride quality.

Track Roller
The computer determined track roller placement and special quad roller rear bogies achieve a smoother ride.

Cat D3 Track Rails
The Cat D3 track rails include sealed tracks with split mater link for dependable, low maintenance performance.

Track Tensioning System
The AP-1050B undercarriage has an automatic track tensioning system for lower maintenance and fewer adjustments.

Increased Tractive Effort
The standard rubber track pads provide increased tractive effort. A two bolt attachment system provides easy pad replacement.

Simplified service means more paving and less maintenance time.

Doors and Panels
Large swing-open doors and panels provide access to all service areas.

Engine Mounting
Transverse engine mounting provides ground-level access to hydraulic pumps and engine cooling system.

Wiring System
