Abstract
Disclosed is an extraction press assembly for facilitating removal of an object from a bore of a structure. The extraction press assembly comprises a coupling mount, a base plate, a support structure, and a press. The coupling mount can be configured to couple to the structure, thus securing the extraction press assembly to the structure. The base plate can be axially spaced from the coupling mount, and can support the press. The support structure can comprise axial extensions coupling the coupling mount to the base plate, and facilitating adjustment of the base plate (and thus the press) relative to the coupling mount. The press can be located between the coupling mount and the base plate and can be configured to expand and contract axially, and to exert a pressing force upon an extraction pole of an extraction pole assembly within the bore, which force is transferred to the object lodged within the bore. The press can be pivotally coupled to the base plate to rotate between a first position for extracting an object and a second position for accessing the bore.
