| Heavy-Duty Mounting Platform Heavy-duty mounting platforms provide rigid support for screed plates, which simplifies leveling. | ||
| Screed Plate Leveling The screed plate leveling system incorporates a threaded bolt design that provides quick adjustment. | ||
| Quick And Convenient Screed plate leveling is quick and convenient with the trailing edge adjusting system. | ||
| Trailing Edge Adjusting System The trailing edge adjusting system saves time when installing new screed plates or when adjusting existing plates. | ||
| Extra Corrosion Resistance The trailing edge adjusting bolt system hardware is plated to provide extra corrosion resistance. | ||
| End Gates The spring-loaded end gates create a downward force to help contain the asphalt and follow the profile of the surface being paved. | ||
| Spring-Loaded End Gates 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 False-wall design reduces mix contact with the sliding portion of the gate, providing easy gate adjustments. | ||
| Bolt-On Design Bolt-on design allows easy end gate installation and removal. | ||
| Replaceable Wear Strip Replaceable wear strip enhances end gate service life. | ||
| Full-Length End Gate Full-length end gate contains material, providing an optimal longitudinal joint. | ||
| Triangular Extender Configuration Each extender is supported by two extendible support tubes and a third frame member to form a triangular configuration that provides torsional resistance and rigidity. | ||
| Support Provided For Each Extender Two extendable support tubes and a third frame member provide support for each extender. | ||
| Visual Graduated Scales Visual graduated scales indicate the distance that the extenders move in or out. | ||
| Hydraulically Driven Vibrators Hydraulically driven vibrators located on the extenders are synchronized with the main screed to match frequency and amplitude. | ||
| Vertical Height Adjustment Vertical height adjustment allows the extenders to match the main screed height. | ||
| Adjustable Plate 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. | ||
| Diesel Screed Plate Heating System The Extend-A-Mat 8-16B offers a diesel screed plate heating system. The diesel screed plate heating system is highly efficient and provide fast warm-up. The diesel heating system features four burners and glow plug ignition. | ||
| Four Diesel Fuel Burners Four diesel fuel burners, two on the main screed and one on each extender, provide fast screed plate heating. | ||
| Even Heat Distribution 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 Full-length insulation over the combustion chamber enhances heating efficiency and minimizes heat transfer to the screed frame. | ||
| Glow Plug Ignition Glow plug ignition is actuated from the main screed control boxes. | ||
| Built-In Timer A built-in timer allows 15 minutes of screed plate heating, preventing overheating of the plates. | ||
| Electric Screed Plate Heating System he Extend-A-Mat 8-16B offers an electric screed plate heating system. The electric screed plate heating system is highly efficient and provide fast warm-up. The electric heating system features an integrated generator and multi-zone heating elements for even heat distribution. | ||
| Heating Elements 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. | ||
| Even Heat Distribution Multi-zone heating element configuration provides even heat distribution. | ||
| Screed Control Panel Screed control panel includes three temperature settings that are able to accommodate normal hot mix asphalt and extended temperature based mixes. | ||
| Regulated Screed Plate Temperature Controller automatically regulates the screed plate temperature to the selected setting. | ||
| Minimal Operator Training On-board diagnostics and screed control panel require minimal operator training. | ||
| Generator System (Tractor Option) The generator system supplies power to the optional electric screed heat and to the optional auxiliary power supply panel. | ||
| Industrial, Single-Phase Generator Industrial, single-phase generator operates at 1800 rpm, includes GFCI breaker protection and provides low sound levels. | ||
| Single Control Switch Single control switch located on the tractor’s operating console activates the generator. | ||
| Full Power Full power is provided to the electric screed and the optional auxiliary power panel while the engine is operating at idle speed. | ||
| Dual Bearings Dual bearings with seals extend service life and internal electronic voltage regulation provides consistent power. | ||
| Auxiliary Power Panel (Tractor Option) The optional auxiliary power panel supplies 8 kW of power for night-time lighting and job-site work tools. The panel includes four 120-volt receptacles and two 240-volt receptacles. | ||
| Auxiliary Power Panel Optional auxiliary power panel provides 8 kW of power and includes four 120-volt and two 240-volt receptacles. | ||
| Ground Fault Circuit Interruption The 20-amp receptacles are circuit breaker protected with ground fault circuit interruption (GFCI). | ||
| Auxiliary Power Panel Door Auxiliary power panel door can remain closed while power cords are attached to the receptacles providing protection. | ||
| Serviceability The Extend-A Mat screed is easy and fast to service and maintain with special emphasis given to component access. | ||
| Easy Service And Maintenance The screeds have been designed for easy service and maintenance with special emphasis given to component access. | ||
| Hydraulic Hoses And Electrical Wiring Hydraulic hoses and electrical wiring harnesses are cleanly routed and clamped to reduce wear and provide easy service. | ||
| Diesel Fuel Burner Lines 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 Remote-mounted fittings for vibrator bearings provide simplified lubrication access. | ||
| Hydraulic Leaks O-Ring face seal fittings and couplings provide maximum protection against hydraulic leaks. | ||
| Nylon Sleeve Protection Exposed hoses have nylon sleeve protection to reduce abrasion. | ||
