Lifting machinery refers to material handling machinery that lifts or lifts heavy objects, and is a type of machinery that works intermittently to lift heavy objects. Generally speaking, during the operation of lifting machinery, material collection, transportation, and unloading are carried out sequentially, and the work of each corresponding mechanism is intermittent. Frequent start stop, heavy load, impact load, dust pollution and other harsh working conditions are common phenomena in lifting machinery equipment. KMR provides various high-performance bearing solutions for the lifting machinery industry.
