Sliding surface element for ski-jump equipments, has rectangular substructure-surface element, and two block elements which are provided at both external longitudinal edges of substructure-surface element

摘要

The sliding surface element (10) has a rectangular substructure-surface element (12), and two block elements (16) which are provided at the both external longitudinal edges (14) of the substructure-surface element. A base element (24) is made of polymeric material, which is fixed on the substructure-surface element between the block elements. The substructure-surface element is formed with channels (50) which are provided parallely in longitudinal direction of the substructure-surface element and are arranged to the ski-tracks (22).
