By its use, one man can raise evenly longpieces, motor truck bodies, etc., etc. Still another variation is the hoist with a hand wheelextension which is especially valuable when the heatfrom a furnace or the size of the work to be lifted issuch that the operator cannot stand directly under-neath the hoist.
