The VF 500 is the 8-ft. (2.4 m) version of the 10-ft. (3 m) VF 600 screed, introduced as the VF 600-2 at World of Asphalt 2012.

The front-mount VF 500 screed from Vögele is designed for use with the 8-ft. (2.4 m) tracked Vision 5100-2 and wheeled Vision 5103-2 pavers.

The VF 500 is the 8-ft. version of the 10-ft. (3 m) VF 600 screed, introduced as the VF 600-2 at World of Asphalt 2012. Also available for the 10-ft. tracked Vision 5200-2i and wheeled Vision 5203-2i pavers is the rear-mount VR 600 screed from Vögele.

With front-mount screeds, extensions are bolted onto the front of the screed, permitting screed extension and retraction without trapping material — compared to rear-mount screeds — allowing versatility on applications with varying requirements, such as parking lots with islands and light poles, residential and city streets with storm sewers, gas and water mains, intersections on major highways and county roads with multiple obstructions. Also, their short end-gates minimize required hand work, according to the manufacturer.

The new Vögele VF 500 extending screed is equipped with vibration across the full paving width, up to 15 ft. 6 in. (4.7 m). Its basic width is 8 ft., and it can be extended hydraulically up to 15 ft. 6 in. With bolt-on extensions fitted, it builds up to a maximum width of 21 ft. 6 in. (6.5 m).

The screed is controlled easily and intuitively through Vögele’s ErgoPlus operating system, via two fixed consoles on the main screed and two remote control units. The display of the ErgoPlus console allows the screed operator to monitor both the left and the right side of the screed. Machine-related parameters such as vibration speed or auger speed can be adjusted conveniently via the display of the screed console.

An advanced electric screed heating system ensures uniform heat distribution all over the screed plates and short times required for heating. A three-phase generator is installed for constant and uniform heating of all compacting and smoothing elements. Excellent thermal insulation of the screed plates minimizes loss of heat. It also ensures that heating the screed to operating temperature takes a short time, even with the engine running at minimum rpm.

The screed operator can select manual mode or automatic mode for conveyors and augers. There also is a reversing auger rotation function.
