ABSTRACT:
A concrete slip former having a hopper mounted on ground-supporting wheel assemblies with a front steerable wheel and a pair of tandem individually mounted rear wheel assemblies connected to the hopper through vertical jack adjusting means to control the height and level. The hopper has an open bottom from which an open bottom mold extends rearwardly to shape the concrete mixture as the machine moves forwardly. A paddle assembly is mounted in the hopper for rotation about an axis transverse to the direction of travel of the machine. The paddle assembly is vibrated by mechanical, pneumatic and/or electrical means during rotation of the paddle assembly.
