When choosing slewing support, we should pay attention to the load of slewing support. The greater the load of slewing support, the more weight it can bear. Therefore, we should choose the appropriate slewing support according to the type of work.
Rotary bearing is a kind of special bearing, which can bear the combined load of axial load, radial load and overturning moment at the same time. Therefore, the maximum bearing capacity of each load should also be considered when choosing rotary bearing. In the actual use process, try not to exceed the maximum load, so as not to cause damage to the slewing bearing. If the slewing support is used under overload, there may be stuck and can not rotate. This time, the body can be tilted by reducing the amplitude, adjusting the position of the leg or moving the chassis, so as to help realize the slewing movement of the weight and complete the scheduled lifting operations. If the slewing bearing has been damaged, it should be repaired to avoid greater damage. Therefore, in order to increase the service life of slewing bearing, it is necessary to calculate the maximum load and select the appropriate slewing bearing.
