Abstract

A semi-trailer landing gear, in particular to support trailers, with a support element which includes an outer sleeve and an inner sleeve and which can be displaced in a telescopic manner in relation to the height. The outer sleeve includes a securing flange which can be applied to a vehicle. The aim of the invention is to develop a semi-trailer landing gear which is economical to produce and can also withstand high loads. The aim is achieved by virtue of the fact that the outer sleeve and the securing flange are made of a single piece of flat steel by edge rolling.
