ABSTRACT:
The invention is directed to a concrete placing boom assembly for use with two trucks. The assembly includes a base frame and a rotatable turret rotatably mounted on the base frame. A foldable boom is pivotally connected to the turret and includes a plurality of boom arms articulately connected one with the other so as to be unfoldable to define an extended boom and foldable to define a stack. The foldable boom is separable at a separation location into two sections transportable on respective ones of the trucks. The assembly of the invention makes it unnecessary to provide auxiliary assembly apparatus for coupling the two sections together.
