ABSTRACT OF THE DISCLOSURE A device for controlling hydraulic distributors in a suspender of hoisting means, comprising a closed casing filled with a liquid substance and containing a ball, the casing being mounted to tilt about a pivot fixed to the suspender frame, a stop being provided for controlling at least one of the hydrau- lic distributors. The closed casing has a bottom which is flat and is provided with two adjustable horizontal guide rails for the ball. Each of the guide rails is connected to the bottom of the casing by means of a vertical pivot. At least one end of each of the guide rails is coupled with the corresponding end of the other guide rail by means of a tension screw the position of which is determined by a link fixedly attached, to the inside wall of the closed casing facing the ball, while a vertically oriented adjustable elastic dog is secured to the outside wall of the casing opposite the inside wall. This device can be used in all cases where the necessity of espe- cially repeated manipulation of loads, the centre of gravity of which is beyond their axis of gravity, occurs and where a quick, safe as well as often considerably accurate balancing of loads to assume the horizontal position, is desired.
