PRESSURE COMPENSATED PUMP.
The parallel circuit of the pump allows for activation of multiple functions at the same time with no loss of speed or power and allows for improved integration of automatic grade and slope control systems.

INDEPENDENT CONTROL.
Independent control of the left and right side conveyors and augers provides versatility for the contractor. Utilized with optional inner and outer cut-off shoes enables paving from 0 to 8’ (2.4 m).

CUT-OFF DOOR VERSATILITY.
Two independent cut-off doors prevent spillage and reduce clean-up between passes. Eye-level indicators, when standing on the screed, signals the operator when the doors are open or closed. The doors are programmable to close automatically when in reverse.

9-TON HOPPER.
The 9-ton (8.1 mt) hopper promotes efficient operation while the rounded design reduces cold material buildup and simplifies clean-out. Independent control of each hopper wing allows for paving next to buildings and obstacles.

PUSH ROLLER OPTIONS.
The standard oscillating push roller pivots to manage trucks in tight spaces and offers six positions to match your trucking fleet. The optional hydraulic push roller features 8” (203 mm) of adjustment. The narrow, 23” (584 mm) width of the push roller and low front apron height of 19” (482 mm) allow for improved truck engagement with the paver.

PAVING RANGE.
Hydraulically extendable standard paving range of 8’ to 15’ 8” (2.44 m - 4.80 m). With the cut-off doors closed, paving range from 0 to 3’ 10” (0 - 1.1 m). Optional cut-off shoes allow paving less than 8’ (2.4 m) within the main screed.

THERMOSTATICALLY CONTROLLED.
Thermostatically controlled, electric heated screed plates are powered by a tractor-mounted 12 kW generator. Four heating elements ensure consistent temperature across the screed. Screed heat is programmable and controls heating elements to maintain temperature.

INTEGRATED SONIC SENSORS.
Standard sonic sensors are integrated into the end gates to ensure proper alignment for controlling head of material. Hard-wired cables are protected from crew members, tools and obstacles.

MULTIPLE ADJUSTMENTS.
Operator friendly adjustment handles along with crown, extension height, extension slope and extension angle of attack adjustments create optimal mat quality. Power crown, slope and extension height options available.

HEATED END GATES.
The optional heated end gates feature a heating element for improved joint matching and reduced hand work for crew members. 

GRADE AND SLOPE CONTROLS.
The P385B is pre-wired to work with multiple grade and slope control systems. Sensor and control panel mounts provide clean working environment. 

CAT 3.4B Tier 4 ENGINE.
The Cat 3.4B Tier 4 engine with 100 hp (74 kW) provides clean, quiet power. A passive regeneration cycle ensures no down time for regeneration. 34 gal (129 L) fuel capacity allows for a full day of paving without re-fueling.

LARGEST UNDERCARRIAGE.
Best-in-class 90” (2286 mm) track length with 68” (1727 mm) of ground contact and 140 mm track chain pitch provides smooth ride and excellent flotation. Automatic track tensioning ensures performance and maximizes component life.

HIGHWAY CLASS CHAINS.
Highway class chains and conveyor and auger bearings provide long-term reliability. Remote grease lines located on the front of the counter weight provide easy daily maintenance.

COOLING PACKAGE.
Largest-in-class, hydraulically-driven, thermostatically controlled cooling package directs air in from the sides and is exhausted out and up through the hood, away from the operators.

RE-BUILDABLE MACHINE.
The P385B is designed to be re-buildable with replaceable floor plates in the hopper to maximize paver life and lower operating costs. Performance poly track pads are individually replaceable if damaged.

HYDRAULIC GENERATOR.
Hydraulically-driven generator runs with the engine at lower rpm to heat the screed. Generator is only turning when it needs to for increased life and less fuel consumption. Generator is located in a clean, protected environment, easily accessible from the right side of the machine.

THREE OPERATING POSITIONS.
Three different operating positions meet crew requirements. Top position provides good visibility into the hopper, mid-level enables clear views of the auger chamber and screed while screed-level allows complete control from the screed.

DUAL OPERATING STATIONS.
The dual operating control stations are identical for maximum efficiency. Stations come standard with steering wheels with propel levers option available. Paving functions are active on both panels at all times. Steering and propel control functions are interchangeable with the push of a button.

INTELLIGENT STEERING.
Weiler’s intelligent steering controls the responsiveness of the wheel based on ground speed providing better control at transport speed and in tight spaces. The magnetic resistance wheel has adjustable settings for operator comfort.

PAUSE FEATURE.
Pause mode stops the paver without having to move the propel lever, allowing for consistent paving speed throughout the job. Feeder system can be set to remain on, or turn off when paused, based on operator preference.

POP-UP CONTROL PANELS.
Optional, screed-mounted control panels are located on each side of the screed and provide operators with complete control of all paving functions including tow point, cut-off doors, head of material and dump hopper.

HAND HELD REMOTE PENDANTS.
Optional remote pendants with magnetic mount include adjustments for tow-point height, extension width and auger override, enabling the operator to control the screed from ground level. 

REMOTE GREASE FITTINGS.
Remote grease lines are grouped and located in easy-to-reach locations for quick work of daily grease requirements. 

SPRAY DOWN SYSTEM.
Toggle switches, located on each side of the machine, engage the spray down pump on an adjustable timer system. A 25’ (7.6 m) hose reel and 10’ (3 m) coiled hose provide complete machine coverage from the separate 10 gal (37 L) spray down tank.

ENGINE ACCESS.
Five large doors provide exceptional access to the engine and hydraulic components. All filters are located behind a single door for simplified servicing. 

ELECTRICAL SYSTEM.
Braided harnesses and sealed connections offer optimal reliability. Color-coded and numbered wires, along with the 12V system with automotive fuses, simplify service. CANbus communication features reduced wires for increased reliability.

ELECTRONIC CONTROLLER.
The electronic controller provides machine diagnostics and machine calibration. Mounted in the center of the machine allows visibility for all crew members.

CAT DEALER SUPPORT.
Weiler equipment is sold and serviced exclusively at Caterpillar dealers. In-stock replacement parts and factory trained technicians keep your machine up and running with limited machine down time.
