发明名称 Hoisting yoke
摘要 A hoisting yoke for a load. At its ends the beam or frame of the yoke has points of suspension for the load and a hoisting point. The hoisting point is displaceable for distributing the weight of the load uniformly over the points of suspension. The beam or frame of the yoke is provided with hoisting points at its opposite ends. The intermediate hoisting point is displaceable dependent on the load picked up by the hoisting points at the ends such that all of the hoisting points carry an equal part of the load.
