Abstract
A telescopic supporting device for heavy loads of trailers is disclosed which device has a supporting leg projecting from a guiding tube and on the lower end of the supporting leg there is detachably fastened an articulated foot. The foot features a supporting plate which has fastened thereto a holding ring. The lower terminal section of the supporting leg has a ground plate that overlaps the lower edge to laterally jut out. A coupling articulately connects the holding ring with the supporting leg, the coupling being provided with a bolt system traversing diametral circular holes. An elastic compression body is placed between the ground plate and a supporting plate. The upper terminal section of the holding ring overlaps the laterally jutting-out edge section of the ground plate. The supporting leg and the ground plate are separated. To the ground plate there is fastened a supporting tubular sleeve, that fits within the leg. The bolt system transverses diametral circular holes in the supporting sleeve wall and the bolt system is countersunk in circular holes in the supporting leg wall.
