发明名称 METHOD OF CONNECTING CRANE SUSPENSION ASSEMBLY SECTIONS TOGETHER AND FRAME MOUNTED ASSEMBLY USED THEREFORE
摘要 A method of connecting sections of a crane suspension assembly together includes attaching a frame to a member of a first section; connecting a tension member between the frame and a connector used in the assembly; moving the tension member so that the connector pivots about a pin to a position where a second hole in the connector is in alignment with a hole in a second section member; putting a second pin through the hole in the connector and the hole through the second section member; and disconnecting the tension member from the connector. The method may also include attaching a frame with a winch to a section of the crane suspension assembly; connecting a line from the winch to the connector; activating the winch to move the connector so that it pivots about a pivot axis; and securing the connector in its second position.
