Hydraulic tamper stroke adjustment

As it is very time-consuming to adjust the tamper stroke mechanically, it is often not adjusted at all, which means that different layer thicknesses are frequently paved at the same setting. VÖGELE developed the hydraulic tamper stroke adjuster to stop this. The Dual Power Shift Tamper enables paver operators to set the ideal tamper stroke for the paving task in question quite simply at the touch of a button.

Quick and easy

It’s very time-consuming to adjust the tamper stroke mechanically, because the eccentric bolts on every bearing have to be adjusted manually. As an example: for a pave width of 12 meters (39.4 feet), 16 eccentric bolts need to be adjusted. Calculating 8 to 10 minutes per bearing, that will take more than 2 hours. The consequence is that the tamper stroke is often not adjusted during mechanical adjustment.

The technology behind the hydraulic tamper stroke adjuster is perfectly simple: altering the direction of rotation of the eccentric tamper shaft adjusts the tamper stroke. Depending on configuration, this is either 2 and 4 mm (8 and 0.16 in) or 4 and 8 mm (0.16 and 0.32 in). This allows high-quality paving results to be achieved much more conveniently, and saves an enormous amount of time compared to mechanical adjustment.

The hydraulic tamper stroke adjuster is available for the following latest-generation extending screeds: AB 500 and AB 600 and for the following fixed-width screeds: SB 300 and SB 350.
