Fixed-width screeds from VÖGELE deliver absolutely high-quality, perfectly even results. Their strengths come to the fore when laying down asphalt across pave large widths and thick base courses. The SB 300 Fixed-Width Screed offers a wide range of applications, covering pave widths of 3m to 16m and layer thicknesses of up to 50cm, depending on the tractor unit.Mehr anzeigen Weniger anzeigen
VÖGELE sets the benchmark with products that deliver a phenomenal degree of precompaction in the paving process. Cutting-edge technology and the most advanced materials guarantee the outstanding performance and reliability of VÖGELE compaction technology. This applies to all VÖGELE compacting systems, from vibrators all the way to the VÖGELE high-compaction system with tamper and pressure bars.
This consists of the compacting systems tamper and vibrators and is already delivering convincing compaction values which are exceeded only by the VÖGELE high-compaction system with pressure bars.
V is for vibrators: For ideal grain size distribution in the pavement
An eccentric vibrator makes the screed plate and frame vibrate to ensure optimum grain size distribution in the mix. This is a prerequisite for achieving a pavement with a particularly smooth surface texture. Just as with the tamper, vibration power can be controlled from the ErgoPlus screed console via the speed of the drive shaft.
T is for tamper: Compaction with a precisely adjustable stroke
A correctly set tamper is of key importance for the compaction result and for the floating behavior of screeds. To this end, the speed on all VÖGELE screeds can be adjusted accurately and easily.
The SB 300 and SB 350 Fixed-Width Screeds, together with the two large AB 500 and AB 600 Extending Screeds in the high-compaction variants, also have a tamper stroke setting. This allows the tamper to be adjusted perfectly to suit the quantity and type of mix and the thickness of the pavement. Hydraulic tamper-stroke adjustment is even available as an option on fixed-width screeds.
The pressure bars driven by pulsed-flow hydraulics are the core of VÖGELE high-compaction technology. By combining screed versions TP1, TP2 and TP2 Plus with this unique technology, our pavers achieve maximum compaction values. Compaction performances of over 98% can be achieved with VÖGELE’s unique high-compaction technology – without rolling.
P is for pressure bars: The pulsed-flow hydraulics power pack
VÖGELE high-compaction technology starts with the pulse generator. It generates high-frequency pressure pulses. These keep the pressure bars in permanent contact with the pavement and force down the mix until it cannot be compacted any more. The reason: The pressure bars are located in the rear area of VÖGELE high compaction screeds. This location enables pavers to achieve the highest possible compaction performance, as the mix is prevented from escaping either to the front or to the sides.
It is possible to switch easily from high compaction to conventional compaction and vice versa from the ErgoPlus 3 control consoles. This allows high compaction screeds to be used for standard tasks as well.
VÖGELE has put its faith in electric screed heating for decades. This extensive experience, in combination with continuous further development, means that VÖGELE screeds are now brought to temperature quickly and evenly.
Quick to reach temperature, efficient in operation
During paving, the intelligent generator management system ensures that regardless of engine speed, the generator output required for an optimum temperature of the full paving width is always available – whether the machine is being operated with or without bolt-on extensions. This reduces both the energy required and fuel consumption.
For an even surface structure
The heating elements of the screed heating work where heat is required: at the point of contact with the material. Maximum insulation of the heating elements of the screeds is towards the top, directing 100% of the heat to where it is required. The compacting systems (tamper and pressure bars) are rapidly and evenly heated from the inside by heating rods. In combination with the latest control technology, this means the entire heating capacity can be controlled automatically.
VÖGELE screeds feature leading-edge technology made possible by state-of-the-art production processes. The first of these processes, the precision cutting to shape of extremely wear-resistant sheet steel, takes place on laser cutting stations. Robots which operate continuously to a consistently high standard ensure long-lasting, stable welds.
Hardened for intensive material contact
Screeds are a key factor in the surface quality and evenness of asphalt layers. At VÖGELE, they are made of wear-resistant Hardox steel. The compacting systems (tamper and pressure bars), too, are ready for harsh operating conditions. As the whole of the heat treatment process is key for their quality and service life, the technology leader puts its faith in induction hardening. This is a process which reduces wear and guarantees longevity by means of greater effective hardening depth and maximum evenness.
Comprehensive quality control
Once the screed and its electrical and hydraulic components have been assembled, all the functions are checked. This check comprises several hundred items including settings, filling levels and pressure tests. All the measured values are documented in a Final Inspection Record. Any discrepancies are remedied immediately by experienced VÖGELE experts.
