The Wirtgen Group is the world market leader in concrete paving machines. Wirtgen offers Offset & Inset range of concrete pavers. Offset pavers are used to produce monolithic concrete profiles such as protective concrete walls, kerb profiles, gutters or narrow paths. With offset slipform pavers, the concrete is transported into the offset mold via a loading conveyor or a conveyor auger. The offset mold can be mounted on the left or right-hand side of the machine. A number of molds in a wide range of different shapes & sizes are available for individual applications. The offset profiles are continually produced monolithically, with or without reinforcements. Machine features include a top-quality machine control system, a practical steering and drive system and stringline-free concrete paving.
In offset application, mixer trucks deliver the concrete into the receiving hopper of the slipform paver. Transport to the mould is effected via a slewable belt or auger conveyor. Depending on the paver model, the belt conveyor is available in different lengths and in folding design. The auger conveyor is also available in different designs. And whether belt or auger conveyor: all settings, such as conveying speed, angle of incline or position can be made at the mere push of a button. A separate cross-feeding auger offers numerous advantages. The mixer truck can drive right in front of the slipform paver, thus eliminating the need to close off additional traffic lanes. The cross-feeding auger is the ideal solution also whenever larger volumes of concrete are required as a material buffer, for example, when paving in narrow bends where it is not possible for the mixer truck to continue the uninterrupted delivery of concrete to the slipform paver.
Inset pavers cost-effectively produce concrete pavements, such as for motorways, arterial roads, runways or railway lines. In addition to single-layer concrete paving, bottom-layer and top-layer concrete can also be paved synchronously in two layers ‘wet on wet’. With inset slipform pavers, the concrete is placed directly in front of the machine and distributed by a spreading auger or spreading plough. Vibrators compact the concrete homogeneously and the mold forms it in the specified width and thickness as the slipform paver advances. Integrated dowel bar and tie bar inserters position dowel bars and tie bars as specified. The finishing beam levels the area transverse to the pavement and the super smoother creates a perfect surface. When paving dual-layer concrete, the bottom-layer & top-layer concrete are processed simultaneously and paved wet-in-wet.
In inset application, the concrete is either deposited right in front of the slipform paver or is fed in front of the machine from the side via a belt conveyor or side feeder. In the next step, the concrete is distributed evenly across the full paving width by a spreading auger or spreading plough. Homogeneous compaction of the concrete is effected by means of integrated electric or hydraulic vibrators. The inset mould forms the concrete slab to the specified thickness and width while the slipform paver advances. In addition, a dowel bar inserter can be integrated which inserts the dowel bars into the concrete as specified parallel to the paver’s direction of travel. Central tie bars or side tie bars can be inserted transverse to the concrete pavement. The surface is levelled off transverse to the paver’s direction of travel by the oscillating beam. The “grinding movement” produces a small concrete roll in front of the beam which adds to the high quality of the concrete surface. In the next step, a super smoother is used to finish the concrete slab.
Over the past 20 years, we have accomplished technical innovations in our products and have built application expertise in concrete paving.
