Screed plates are constructed of abrasion resistant alloy steel that resists damage and provides an enhanced service life.
Curved nose bar design provides precompaction and enhances material flow under the screed.
Nose bar and screed plate replacement are simplified with tapped holes and studs.
Heavy-duty mounting platforms provide rigid support for screed plates, which simplifies leveling.
Screed plate leveling is quick and convenient with the trailing edge adjusting system.
The trailing edge adjusting system saves time when installing new screed plates or when adjusting existing plates.
The trailing edge adjusting bolt system hardware is plated to provide extra corrosion resistance.
Spring-loaded end gates create a downward force that causes the gates to follow the profile of the surface being paved, assuring a good joint with the adjacent mat.
False-wall design reduces mix contact with the sliding portion of the gate, providing easy gate adjustments.
Bolt-on design allows easy end gate installation and removal.
Replaceable wear strip enhances end gate service life.
Full-length end gate contains material, providing an optimal longitudinal joint.
Two extendable support tubes and a third frame member provide support for each extender.
Visual graduated scales indicate the distance that the extenders move in or out.
Hydraulically driven vibrators located on the extenders are synchronized with the main screed to match frequency and amplitude.
Vertical height adjustment allows the extenders to match the main screed height.
An adjustable plate on the inboard side of each extender provides a tight joint in order to prevent asphalt from bleeding between the main screed and the extender.
Four diesel fuel burners, two on the main screed and one on each extender, provide fast screed plate heating.
Burners on main screed and extenders are mounted on a replaceable, baffled combustion chamber with flame deflectors that direct heat to screed plates, providing even heat distribution.
Full-length insulation over the combustion chamber enhances heating efficiency and minimizes heat transfer to the screed frame.
Glow plug ignition is actuated from the main screed control boxes.
A built-in timer allows 15 minutes of screed plate heating, preventing overheating of the plates.
Heating elements provide a warm-up time to 122° C (220° F) in 30 minutes or less when ambient temperatures are 22° C (40° F) and above.
Multi-zone heating element configuration provides even heat distribution.
Screed control panel includes three temperature settings that are able to accommodate normal hot mix asphalt and extended temperature based mixes.
Controller automatically regulates the screed plate temperature to the selected setting.
On-board diagnostics and screed control panel require minimal operator training.
Industrial, single-phase generator operates at 1800 rpm, includes GFCI breaker protection and provides low sound levels.
Single control switch located on the tractor's operating console activates the generator.
Full power is provided to the electric screed and the optional auxiliary power panel while the engine is operating at idle speed.
Dual bearings with seals extend service life and internal electronic voltage regulation provides consistent power.
Optional auxiliary power panel provides 8 kW of power and includes four 120-volt and two 240-volt receptacles.
The 20-amp receptacles are circuit breaker protected with ground fault circuit interruption (GFCI).
Auxiliary power panel door can remain closed while power cords are attached to the receptacles providing protection.
This screed has been designed for easy service and maintenance with special emphasis given to component access.
Hydraulic hoses and electrical wiring harnesses are cleanly routed and clamped to reduce wear and provide easy service.
Diesel fuel burner lines are equipped with a quick-disconnect coupling that simplifies switching from the screed plate heating system to the wash-down system.
Remote-mounted fittings for vibrator bearings provide simplified lubrication access.
O-Ring face seal fittings and couplings provide maximum protection against hydraulic leaks.
Exposed hoses have nylon sleeve protection to reduce abrasion.
Vibrator system hydraulic lines are constructed of steel tubing, providing durability and resistance to damage.
Integrity of the electrical system is ensured with the use of high-quality components.
The Caterpillar electrical standards, developed to enhance reliability and durability, feature soldered, molded, numbered and color-coded wires. Nylon-braided wrap protects the electrical wires.
Electrical schematics detailing wire numbers, wire colors and component part numbers are located in the service manual.
