Abstract
The present invention provides a novel arrangement for selective mounting and demounting of a mold to a self-propelled slip-form paving machine. The paving machine basically comprises a frame, a drive engine, a hopper for concrete or another suitably flowable paving material and the aforementioned mold in the desired configuration of the pavement (curb, gutter, etc.) to be formed. The mounting and demounting arrangement comprises a set of hydraulically pivotable latching levers which engage with latching bars on the mold for quickly coupling of the mold to and from the machine frame without the necessity of manual manipulation of mounting bolts.
