Abstract: A device relocates an underlift/vertical arm assembly from the end of a sub-frame to the boom of a wrecker, and hence whole space of the end of sub-frame is used to design rear outriggers that will certainly exhibit an excellent performance. An advantage of a large space for this specific application is to design a wider span of rear outriggers, as completely extended, to match that of the front outriggers, and in the mean time, the tip of a rear outrigger has a sufficient strength to maintain a good stability. The increased length of overlapping part in each section of the three stage outriggers assists to achieve this goal. As the three stage outriggers are fully extended, the tip of each right/left side is additionally reinforced by a diagonal folding bar which bridges between an outer vertical barrel and the end of primary inner sleeve. Consequently, a combination of wider spans and higher stiffnesses at the tip of the rear outrigger provides the wrecker with a superior stability.

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.

The lever is sufficiently long to provide adequate mechanical advantage to force the tongue of a loaded trailer upwardly the required distance. The lever may be pivoted in the opposite direction to lower the tongue of the trailer by pulling the inner jack tube within the outer jack tube.
