Anti-friction coating for telescopic crane parts

Abstract

The invention relates to an anti-friction coating for relatively slidable machine parts such as telescopic crane parts, in particular telescopic elements of a crane or mobile crane. A coating of anti-friction lacquer is applied to one of the relatively slidable parts, such as a telescopic crane part substrate. The anti-friction layer is compacted and sliding properties are imparted by incorporating nano-particles therein.

1 . An anti-friction coating for telescopic crane parts, in particular telescopic elements of a crane or mobile crane, comprising a coating of anti-friction lacquer and an additive layer applied to a telescopic crane part substrate, said additive layer being compacted and incorporating nano-particles. 
     
     
         2 . An anti-friction coating as in  claim 1 , wherein the anti-friction coating is applied to a substrate comprising a pre-coated fine-grained steel. 
     
     
         3 . An anti-friction coating as in  claim 1 , wherein said nano-particles are incorporated continuously in said additive layer on or underneath the surface of the anti-friction lacquer coating. 
     
     
         4 . An anti-friction coating as in  claim 1 , comprising additives based on siloxane. 
     
     
         5 . An anti-friction coating as in  claim 4 , wherein CH 3  residues are incorporated in the surface of the anti-friction lacquer coating above the siloxane elements of the additive layer. 
     
     
         6 . An anti-friction coating for relatively slidable parts comprising a coating of anti-friction lacquer and an additive layer applied to at least one of said parts, said additive layer being compacted and incorporating nano-particles. 
     
     
         7 . An anti-friction coating as in  claim 6 , wherein the anti-friction coating is applied to a substrate comprising a pre-coated fine-grained steel. 
     
     
         8 . An anti-friction coating as in  claim 6 , wherein said nano-particles are incorporated continuously in said additive layer on or underneath the surface of the anti-friction lacquer coating. 
     
     
         9 . An anti-friction coating as in  claim 6 , comprising additives based on siloxane. 
     
     
         10 . An anti-fiction coating as in  claim 9 , wherein CH 3  residues are incorporated in the surface of the anti-friction lacquer coating above the siloxane elements of the additive layer.
