Abstract

This lift bail enables the assembly technician to lift and install the heavy circuit boards in computer frames in a safe manner for the installer and without any potential damage to the board. The lift bail consists of a spider clamp gripper 10 with four pockets which are configured to engage with the mushroom shaped heads of handles 12 for the board 14. A locking plunger (not shown) is actuated manually to prevent the board 14 from slipping out of the four pockets during installation. The gripper or spider clamp frame 10 is attached to the bail 18 via a pivot bearing 20. The gripper can be pivoted from a horizontal position to a vertical position by means of a lever handle. The vertical position is the normal installation attitude for placement of the board into the frames.

Board Lift/Installation Bail

This lift bail enables the assembly technician to lift and install the heavy circuit boards in computer frames in a safe manner for the installer and without any potential damage to the board. The lift bail consists of a spider clamp gripper 10 with four pockets which are configured to engage with the mushroom shaped heads of handles 12 for the board 14. A locking plunger (not shown) is actuated manually to prevent the board 14 from slipping out of the four pockets during installation. The gripper or spider clamp frame 10 is attached to the bail 18 via a pivot bearing 20. The gripper can be pivoted from a horizontal position to a vertical position by means of a lever handle. The vertical position is the normal installation attitude for placement of the board into the frames. The gripper can also be pivoted about the "z" axis to enhance or facilitate board installation. The entire lift fixture is suspended from a vertical lift cable through an eyebolt 22 which is attached to an air balance lift.
