The telescopic struts by RESQTEC can withstand 15 tons of weight and are available in various lengths. They are easily extended to the desired length, in which they remain stable when bearing weight, thanks to their patented locking system that does not require pins, ensuring speed and safety. They can secure a vehicle from tilting uncontrollably or support a structural element from collapsing. Also, when combined with an air supply, they can follow the lifting arc of a large object (e.g. truck, train car) while lifting it, to make room for the victim below.
