Abstract

The invention relates to a chain elevator comprising an elevating chain (1) made up of links (2) attached to each other, whereby the planes formed by adjacent links are primarily at a 90.degree. angle in relation to each other; an elevating element (3) having a driven chain gear (7) arranged to it, the elevating chain (1) being led to couple with the driven chain gear from the fixing point (9) of the fixed end (8) of the elevating chain located above the driven chain gear (7); and a driving chain gear (100) located above the driven chain gear (7), the elevating chain being led to couple with the driving chain gear from the driven chain gear (7). The fixing point (9) of the fixed end of the elevating chain is moved aside from the rotating plane (A) of the driving chain gear (100) so that the shaft (7a) of the driven chain gear is substantially at a 45.degree. angle in relation to the shaft (100a) of the driving chain gear when seen from above or below, the plane formed by every second link (2) of the elevating chain coupled to the driven chain gear (7) being substantially parallel with the shaft (7a) of the driven chain gear and every other link being substantially perpendicular in relation to said shaft, and the plane formed by each link (2) of the elevating chain coupled the driving chain gear (100) being substantially at a 45.degree. angle in relation to the shaft (100a) of the driving chain gear.
