ABSTRACT:
Apparatus and methods for manipulating concrete products having first and second ends. The apparatus comprises first and second engaging assemblies for engaging the first and second ends of the product. The engaging assemblies are mounted on a structural assembly. At least one of the engaging assemblies is displaced along the structural assembly towards the other of the engaging assemblies to grip the concrete product therebetween. A rotational actuator may be provided for each of the engaging assemblies for rotating the concrete product from a casting orientation into an installation orientation. The structural assembly may accommodate one or more sets of engaging assemblies and may be designed to allow fine adjustment of these assemblies relative to the concrete products to be manipulated.
