Embodiment Construction

[0016] like figure 1 As shown, the coated elements of a pair of sliding parts proposed by the present invention are based on the following structure. Underneath the paint surface 1 is first the additive layer 2 with CH directly under the surface 3 residues, and located at CH 3 Residues under the Si element (Si) of the siloxane additive. The additive layer is bonded to the substrate 4 via siloxane bonds (conventional repeating Si-O-Si bonds) indicated by reference numeral 3 and the added nanoparticles result in a smooth surface optimized for sliding purposes. In this particular case the substrate is a steel surface, although it could in principle be any type of substrate.

[0017] figure 2 The microscopic images (observed in cross-section) of the coated film in , show the compaction achieved by the nanoparticles (siloxane additive), which leads to a smooth coated film and reduces the number and degree of irregularities. The additive is placed continuously throughout the a...

Abstract

The coating has an anti-friction paint layer which is applied on a telescopic crane part substrate (4) and is made in a compressed and sliding manner by the storage of nano particles. The substrate is made up of fine grained steel such as grounded fine grained steel, and the nano particles are continuously accumulated as an additive on and / or below a surface (1) in an additive layer (2) of the paint layer, and the additive is used on a siloxane base.

Description

technical field [0001] The present invention relates to anti-friction coatings for telescoping crane components. In particular, the invention relates to anti-friction coatings for telescoping elements of cranes or mobile cranes. Background technique [0002] In the case of crane jibs, a grease coating is typically used for pairs of telescoping parts where one part slides inside the other and has to be replaced periodically by a rolling process or a spraying process. Grease coatings are also suitable for other pairs of sliding parts or applications, eg in the case of support systems where one part slides over the other in order to assume a chosen final position. [0003] Lubricants used for this purpose are relatively expensive as they must be of high quality and environmentally friendly. Lubricant application during initial assembly involves several jobs and leads to high costs on the one hand and high maintenance costs for the operator on the other. The purpose of the lu...
