Portable device for road-building, particularly for overcoming height difference, has two telescoping slittings which are spaced apart from each other and plate-like elements which are movable relative to each other between slittings

摘要

#CMT# #/CMT# The portable device has two telescoping slittings which are spaced apart from each other and plate-like elements (3-8) which are movable relative to each other between the slittings. The plate-like elements are assigned with two identical telescopic sections (9) of the slittings. The telescopic sections of the slittings interlock in tubular manner. Cross beams (10-16) are provided at end of each next smaller telescopic section for the plate-like elements. #CMT#USE : #/CMT# Portable device for road-building, particularly for overcoming a height difference. #CMT#ADVANTAGE : #/CMT# The portable device has two telescoping slittings which are spaced apart from each other and plate-like elements which are movable relative to each other between the slittings, where the plate-like elements are assigned with two identical telescopic sections of the slittings, and hence ensures improved and space-saving portable device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of a portable device. 3-8 : Plate-like elements 9 : Telescopic sections 10-16 : Cross beams 19 : Curve 21 : Support unit #CMT#POLYMERS : #/CMT# The plate-like elements are formed of flexible, rigid plastic.
