A device for handling connector pins, that is, for inseting and removing pins from alined holes in structural members, comprising a pair of frame plates notched to fit over the structural members and which are formed to receive the hydraulic jack and pump of a conventional tool so that extension of the jack moves the connector pin into or out of position. For insertion, the frame receives a pin in alinement with holes in the structural member, and for removal the frame includes a tray for receiving the pin when it is pushed free. In each case, extension of the jack causes pin movement. The center of gravity of the device, and a suspension member, is to the jack side of the notches so that the device can be manipulated at one side of the lower cord of a crane boom, for example. Jack piston extensions and pin handling tools are provided.
A device for handling connector pins comprising, in combination, a pair of frame plates having alined notches to fit over structural members with holes to receive connector pins, said plates being connected with a butt plate and a bed plate defining a jack receiving trough, a hydraulic jack with a piston in a cylinder rested in said trough, said plates and trough being sufficiently long to receive a pin between said notches and said jack when said piston is in said cylinder and the jack is adjacent said butt plate so that hydraulically extending the piston will force the pin transversely of the notches and into holes in members in said notches, said frame plates having a pin receiving tray on the side of said notches opposite said jack for receiving the pin when the jack is used to force a pin from members in said notches, and a pin carrying tool having a handle and a pin embracing portion, and a pair of auxiliary push pins for extending the reach of said jack by being inserted between said jack and a connector pin, and said side frames having sockets for storing said push pins and hooks for storing said tool.
