In offset applications, a concrete mixer transfers the concrete to the receiving hopper. The material is transported into the slipform via a swivel-mounted conveyor belt or a swivel-mounted auger conveyor. Depending on the machine model, the conveyor belt is available in various lengths and in a folding version. Different versions of the auger conveyor are also available. Whether conveyor belt or auger all of the settings such as conveyor speed, inclination angle, or position can be adjusted at the touch of a button. An additional transverse auger conveyor offers many benefits. For example, the concrete mixer can travel in front of the slipform paver and not need to be off to the side, thereby eliminating the need to close another lane. Despite the fact that a larger quantity of concrete is required as a buffer, the transverse auger conveyor is still an ideal solution like in tight bends where the concrete mixer is unable to permanently supply the machine with concrete, for example.
Concrete feeding system offering various adjustment options. Flexible arrangement of the offset mould on the left or right side, close to or far to one side of the machine frame. Most diverse offset moulds for poured-inplace profi les available for a wide of applications.
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 plow. Built-in electrical or hydraulic vibrators ensure homogeneous compaction of the concrete. The inset mold forms the concrete surface to the specified thickness and width while the slipform paver travels forward. In addition, a dowel bar inserter can be added which inserts the dowel bars into the concrete as specified parallel to the pavers direction of travel. Central tie bars or side tie bars can be inserted perpendicular to the road surface. The oscillating beam scrapes the surface across the roadway. The grinding movement produces a small concrete roll in front of the beam which enhances the high quality of the concrete surface. Afterwards, a super smoother can smooth the concrete surface.
Compact dimensions and minimum modification requirements ensure ease of loading and cost-effective transport. Depending on the pavers configuration, the dowel bar inserter or oscillating beam, super smoother and concrete spreading equipment can remain mounted on the machine during transport.
The machine can be equipped with a hydraulic or electric vibrator drive to comply with site requirements. It comes with 24 hydraulic connectors in standard design (optionally 30 or 36) but can optionally be fitted with 26 or 34 electric connectors.

The WPS 62(i) placer speader is normally used in combination with a slipform paver and a texture curing machine. While trucks and semitrailers successively dump concrete into the conveyor belt units large receiving hopper, the conveyor belt guides the conveyed material to the center of the road. The WPS 62(i) placer speader uses a spreading auger to spread the laid concrete and paves it uncompacted with a narrower width and greater thickness than the following slipform paver. Finally, the paver paves the pre-poured concrete in the required width and thickness together with the pre-laid reinforcement. To complete the process, the texture curing machine produces a defined surface structure and sprays evaporation protection onto the fresh concrete road surface.

concrete pavers | construction equipment
Form-riding pavers ride on metal forms that set the boundaries of the paved surface; a typical application for these machines is bridge-deck paving, and the machine typically employs rollers that move transversely over the surface to finish the concrete.
The most widely used machine for paving concrete roadways is the mainline slipform paver, which extrudes a paved surface without the use of forms. Curb-and-gutter machines are a type of slipform paver that can use variously shaped molds to place other than flat surfaces, such as curbs, roadway median barriers, and bridge parapets
The slipform process for mainline machines involves first placing fluid concrete in front of the machine, which, as it advances, uses augers to spread the concrete uniformly across the surface to be paved. A strike-off plate levels the concrete and removes excess material, and multiple, hydraulically driven vibrator tubes (and sometimes mechanical tamper bars) consolidate the concrete. Mainline slipform pavers often also have a dowel-bar inserter, a mechanism that automatically vibrates dowel bars into position to serve as load-transfer devices across pavement joints. Profiling molds (or pans) at the rear of the paver then set the finished grade and elevation of the consolidated concrete, and a finishing mechanism creates an initial texture for the surface.
Many mainline pavers automatically change paving widths without stopping the paving process, eliminating the time-consuming task of mechanically adding or deleting sections of the various paving elements.
