Compared to fixed-width screeds, extending screeds offer the benefit of higher adaptability on the job site when it comes to quickly adjusting the pave width to match requirements. VÖGELE now present their new AB 500-2 Extending Screed. Larger width, more compact design, less noise - these were the main goals pursued by the VÖGELE engineers. Given these attributes, the abbreviation of "AB" may well also stand for "Absolutely the Best".

The new AB 500-2 Extending Screed, compared to the former design, has been improved with many different aspects in mind and a number of innovations have been integrated. It begins with pave width. The screed's basic width is 2.55m, no change has been made to this, and it extends hydraulically to a width of 5m. By addition of bolt-on extensions, however, the new AB 500-2 builds up to a maximum width of 8.5m which, compared to the former design, is an increase of half a metre.

For the new AB 500-2 Extending Screed, the depth of screed plates has been inceased from 300mm to 330mm. Larger depth results in even more stable floating of the screed. The screed plates larger in area feature enhanced wear behaviour and prolonged service lives.

Typical VÖGELE features are service-friendly design and ease of maintenance, so that it goes without saying that VÖGELE engineers also had these aspects in mind when conceiving the new AB 500-2. The tamper shield's design prevents bitumen from getting into the tamper area, thus eliminating the need for time-consuming cleaning. The tamper shield demounts very easily for performing maintenance services. Needless to say that all service points on the new screed are conveniently and quickly accessible. As a very service-friendly improvement, the vibrator shaft has been relocated. In the new screed, the shaft is attached to the screed frame and no longer to the screed plate. As a result, replacement of screed plates or heating rods is much easier and the time replacement takes cut considerably.
