The beam associated with the lower fitting is provided with two bars of different lengths, the bars being pivotally connected to the hoist shaft and to a conical part. Preferably, the total length of the two bars is less than or does not exceed significantly the height of the hoist shaft. The longer bar is connected to the hoist shaft by an outwardly closed, generally U-shaped suspension and securing bail surrounding the bar with play and extending generally transversely to the hoist shaft. The ball is provided with a guide and support for a support bolt secured to the upper end of the longer bar.
