US Patent 7762377 Transport car for metal coils

A transfer car in a conveyance system for metal coils, having a support saddle, a chassis that can be moved along a conveyance path by a drive and a mechanism for raising and lowering the support saddle along a linear vertical guide on a plate-like base frame. A steel slab is used as the plate-like base frame, on which a scissor unit is mounted for the purpose of linear vertical guidance and so as to not take on any lifting forces. Two lifting cylinders are installed some distance apart as the drive and act directly on the support saddle to provide the sole lifting forces to raise and lower the support saddle.
