Abstract: A support jack with a vertically telescopically displaceable supporting element having an outer sleeve and an inner sleeve 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. The vehicle 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 with a pressure element is arranged on the supporting element, the pressure element triggering a signal when a predefinable supporting force is reached.
