SP 154i: Top Layer and Bottom Layer Concrete Paver
As a bottom layer paver, the slipform paver is equipped with an automatic dowel bar inserter, up to three automatic side tie-bar inserters, and a concrete conveyor to the top layer paver. The heavy-duty paving mold paves the concrete true to line and level while the paver moves forward. Electric vibrators compact the concrete. Then dowels and tie bars are precisely inserted into the bottom layer concrete. The result is a homogeneous, cost-effective concrete surface that forms the ideal base for the high-quality top layer concrete.
When using the SP 154i as a top layer paver, the top layer concrete is conveyed over and across the bottom layer paver via a belt conveyor and placed on the fresh bottom layer concrete in front of the top layer paver. The top layer concrete is paved “wet on wet” and compacted with T-vibrators specially designed for top layer concrete. The slipform paver comes standard-equipped with an oscillating beam and super smoother to produce a level surface, while the hydraulically adjustable one-piece or two-piece side plates on both sides minimize concrete loss. Specially designed trailing forms and extended side plates additionally ensure that the slipform paver can produce perfect concrete corners.
Easy Transport and Short Setup Times
The SP 154i stands out for its outstanding maneuverability and traction, regardless of the surface conditions, thanks to its four steerable and slewing crawler units. Making the units independent of each other makes transport easy and results in minimal assembly/disassembly effort. The SP 154i features a high degree of automation, which makes concrete paving extremely cost-effective.
