Abstract:
A chain elevator comprisingan elevating chain made up of links attached to each other, whereby the planes formed by adjacent links are primarily at a 90.degree. angle in relation to each other, and which chain has a fixed end,an elevating element having a driven chain gear arranged to it, the elevating chain being led to couple with the driven chain gear from a fixing point of the fixed end of the elevating chain located above the driven chain gear in such a manner that the elevating element hangs on the elevating chain, anda driving chain gear located above the driven chain gear, the elevating chain being led to couple with the driving chain gear from the driven chain gear, whereby the plane formed by each elevating chain link in said coupling is substantially at a 45.degree. angle in relation to the shaft of the driving chain gear,wherein the fixing point of the fixed end of the elevating chain is moved aside from the rotating plane of the driving chain gear so that the shaft of the driven chain gear is substantially at a 45.degree. angle in relation to the shaft of the driving chain gear in the direction of view defined by the chain section between the driven and the driving chain gear, and that the plane formed by every second link of the elevating chain coupled with the driven chain gear is substantially parallel with the shaft of the driven chain gear and the plane formed by every other link is substantially perpendicular with said shaft.
