According to the characteristics and the operation condition of the crane and the lubrication requirements of crane arm, special grease used in crane arm was developed by adding composite polyurea thickening agent and functional additives into PAG and low viscosity of PAO base oil. Physical and chemical characteristics of the grease were analyzed, and the field test the grease was carried out. The results show that, the developed grease has good thermal oxidation stability, extreme pressure anti-wear ability, engine invariability, good adhesive and anti-water ability; the developed grease has good lubrication and protective effects for crane working and its daily maintenance.
