In this paper,a new stationary crane operating with loads is designed to solve the problems of external foreign matter interference and steel rope management that are often encountered in the operation of traditional cranes,including the easy dislocation and winding of telescopic steel rope in the recovery process and the damage caused by foreign matter mixing.Those problems not only reduce the operation efficiency of the equipment,but also increase the operation risk and maintenance cost.By introducing the design of steel wire brush head,equipment damage caused by foreign matters is reduced,thus prolonging the service life of the equipment and effectively preventing the dislocation and winding of the telescopic steel rope.The new structure also takes into account the convenience and practicability of operation.Accurate control of the working timing and rotating speed of the cleaning roller shaft can ensure that the cleaning process is efficient and no additional wear is brought to the telescopic steel rope.Meanwhile,the structure can also adapt to different environments and working conditions,and has good adaptability and reliability,which improves the operating efficiency and safety of the equipment.
