About the support bearing of a 100-ton crane

A significant simplification of the machine parts of the mechanism for changing the departure of cranes with articulated (breaking) boom has another significant advantage in terms of ease of operation.


Until now, the long spindles for retracting the boom of floating cranes could not be enclosed in a box; therefore, they were not sufficiently wetted with a brush. In contrast, the short spindle of cranes with a breaking boom is protected by a telescopic tube and runs in oil.


Similarly, all parts for the drive are enclosed by an impenetrable casing and located directly at the spindle.


The rotating part of the 100-ton floating crane is built according to the proven and proven bell shape, mounted on a tower fixed on a pontoon.


One of the most important parts for crane operation is the support bearing, which takes on the weight of the turning part.


The special design of the bearing, which accepts not only axial, but also radial forces, is shown. Axial roller bearing of the rotary part of a 100-ton floating crane.


The reaction in the lower part of the bell is perceived in the usual way, with the help of rollers. The bearing is equipped with spherical rollers, which, even in case of misalignment, cannot have a dangerous load on the edges. This is necessary due to the fact that, due to the inaccuracy and deflection of the crane structure, the rolling surfaces of the bearing on the upper rotary part can never be in a position relative to the rolling surface of the ring on the tower in such a position that the conical rollers could fit their entire surface.


The entire bearing is immersed in oil. Electrical cables pass through the inside of the bearing, enclosed in a tube supporting the collector rings.


There are two hooks with a lifting capacity of 50 tons each for lifting cargo. Each hook is suspended at six ends, with a diameter of 34 mm, made of a material with a tensile strength of 160 kg/mm2. In addition, the crane is equipped with a 10-ton auxiliary hook. The winches of a floating crane are shown.


All high-speed winch transmissions operate in oil baths. The coupling couplings in this design were almost completely avoided. Each of the three lifting mechanisms has a separate motor. All shifting gears are completely excluded to increase the lifting speed of light loads. Instead, when lifting light loads, the engine speed increases by 70% due to the weakening of the field.
