Coil shift transfer car
View Patent ↗A system is disclosed for transferring a cylindrical coil suspended on a first stem projecting horizontally from a first base to a remotely positioned and axially aligned second stem projecting horizontally from a second base. The system comprises a track extending between the first and second stems, a carriage movable along the track, and a conveyor on the carriage, with a receiving end and a delivery end. The carriage is movable along the track to a first location at which the receiving end of the conveyor underlies the coil suspended from the first stem. The conveyor is vertically adjustable from a lowered position spaced beneath the coil to an elevated position at which the coil is lifted from the first stem and supported on the receiving end of said conveyor, with the conveyor then being operable to shift the coil to a position supported on the conveyor delivery end. The carriage is then shiftable to a second location at which the coil is axially inserted on the horizontally positioned second stem, with an end of the coil in contact with the second base. The conveyor is then lowered to deposit the coil on the second stem, thereby allowing the carriage to again move along the track to begin another coil transferring cycle.
