ABSTRACT:
A supporting leg for a vehicle that transports exchangeable containers comprises two telescopic tubes and a pneumatic drive for retracting and extending one of the tubes. Thread-type or annular bearing parts comprising a horizontal bearing surface are configured on the inner extendable tube. An engagement part with horizontal bearing surfaces, which interacts with the bearing parts, is located on the outer tube. The engagement part is pre-stressed in its displacement from the disengaged position to the engaged position in a spring-loaded manner and is fixed to the outer tube with a non-positive fit.
