VÖGELE extending screed with front-mounted extensions

The VF 500 Extending Screed has been specially developed for the SUPER 1700-3i and SUPER 1703-3i pavers of the Universal Class. The VF 500 is ideal for applications which require a variable paving width, such as parking lots with islands and light masts, roads for residents only, urban roads with manhole covers, gas or water connections, junctions on highways or work on country roads, i.e. jobs which involve paving around obstacles.

Screed guiding system

The operating principle of all VÖGELE extending screeds is the single-tube telescoping system. Even at maximum extension, half of the three-part, generously-sized telescoping tube is clamped, ensuring optimum stabilization. As the guiding system is arranged at a high level, this prevents any contact with paving mix.

The 3-point support in VÖGELE extending screeds means that torsional forces acting on the hydraulic extensions as a result of the pressure of the mix do not have a negative influence on the guiding system. The point at which the telescoping tube is attached, the bearing for the telescoping tube and the torque restraint system all absorb the forces acting here, guaranteeing strain-free extension and retraction of the hydraulic extensions – without any kind of tilting or jamming.

The 3-point support, an especially resilient part, combines with low-wear sliding bearings inside the telescoping tubes for gentle, smooth adjustment of pave width.

Heating System

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.

Manufacturing Technology

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.
