Concrete placing boom adapter |
摘要 |
A support structure for supporting a concrete placing boom above a work site. The support structure includes a support mast having a generally smooth outer surface. The support mast receives an adapter that can be removed from one support mast and attached to another. The adapter includes a mast receiving portion having a pressure coupling for holding the adapter in contact with the outer surface of the mast. The adapter further includes a boom attachment portion that allows the pedestal of the concrete placing boom to be securely attached to the adapter. The adapter includes a central guide pin that is received within a guide opening formed in a top plate of the support mast. The interaction between the guide pin and the central opening on the mast aids in guiding the adapter onto the mast.
