Vögele's new AB 500 and AB 600 extending screeds and their permutations have an infinitely variable single-tube telescoping system for an immense range of job applications with pave widths from 6.5 to 31 ft. (2 to 9.5 m). The screeds match with all the Super pavers featuring a basic width of 8.3 and 9.8 ft. (2.55 and 3 m).
In addition, they also can be equipped with various compaction systems, including tamper technology, depending on the paver model and application. The large number of possible combinations and different compaction options open up an almost limitless range of job applications for the extending screeds.
Pavement quality is further enhanced by technical innovations in the AB 500 and AB 600 which make the screeds easy to operate. These include easily and precisely adjustable hydraulic side plates, as well as hydraulic crown adjustment, which is integrated as a standard feature, and can be adjusted directly from the screed console. Wear resistance of the screed plates also has been improved, the time required to heat up the screed shortened, and the tamper geometry optimized. All these features make for better compaction and evenness, according to the manufacturer.
The new screeds are distinguished by vibration-damped middle stairs or ascent. The ascent is comfortably designed with low steps and an additional hinged step.
Optimum working conditions are essential, especially for the screed operator. The new screed consoles of the Dash 3 paver generation include a number of innovative features to assist the operator.
