A support jack with a vertically telescopically displaceable supporting element (1) having an outer sleeve (2) and an inner sleeve (3) is described. For the operator, it is sometimes hard to discern whether the support jacks find an adequate abutment on the ground. In an extreme case, the support jack sinks into the ground under the load of the vehicle (14). The vehicle (14) is then no longer adequately supported and can tip over. For this reason, the object of the invention is to develop a support jack in such a way that secure standing is already discernible for the operator during extension of the supporting element. According to the invention, the object is achieved with a support jack in which a supporting load indicator (4) with a pressure element (5) is arranged on the supporting element (1), the pressure element (5) triggering a signal when a predefinable supporting force is reached.
L'invention concerne un vérin d'appui comportant un élément d'appui (1) télescopique en hauteur et doté d'une gaine externe (2) et d'une gaine interne (3). L'utilisateur a généralement des difficultés à voir si un vérin d'appui a un palier porteur suffisant sur le sol. Dans des cas extrêmes, le vérin d'appui s'enfonce dans le sol sous la charge du véhicule (14), lequel n'a plus alors de soutien suffisant et bascule. C'est pourquoi l'invention vise à perfectionner un vérin d'appui de manière à ce que l'utilisateur voit si le vérin a une position stable dès qu'il sort l'élément d'appui. A cet effet, le vérin d'appui de l'invention comporte un élément d'appui (1) doté d'un indicateur de charge d'appui (4) comprenant un élément de pression (5), lequel déclenche un signal lorsqu'une force d'appui donnée est atteinte.
