Hydraulic tamper stroke adjustment
Hydraulic tamper stroke adjustment at the touch of a button
A correctly set tamper stroke is a key factor in both the compaction result and the floating behavior of screeds.
It’s very time-consuming to adjust the tamper stroke mechanically, because the eccentric bolts on every bearing have to be adjusted manually. VÖGELE developed the hydraulic tamper stroke adjustment system for all compaction variants 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
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.
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.
