Abstract
An apparatus for supporting a trailer of a tractor semitrailer has a supporting element that is telescopically adjustable by way of a gear shifting mechanism having a gear input shaft running vertically onto a spindle. In this way, the supporting element has an especially compact construction and can be installed very easily. The gear shift also has a free floating gear between two shift positions and can be shifted very conveniently.
