Tribological properties of resin sliding material and high tensile strength steel material with various coating films used in the boom extension mechanism of construction cranes

Abstract

There is a growing need for grease-free boom extensions on actual cranes. The problem with implementing a greaseless design is that the friction of the sliding parts increases, which can cause material wear. One way to solve this problem is to apply a special coating to the material surface. In this presentation, we will report on the analysis and evaluation of the friction properties of resin sliding material and high tensile strength steel material with various coatings used in crane boom sections using a 3-pin on disc frictional apparatus.
