In a pivotable telescopic support device (5) for a semitrailer, having in each case one telescopic support (9) on each side of the chassis (1) of the semitrailer, which telescopic supports (9) are mounted so as to be pivotable about a transverse axis (6) of the chassis (1) and can be locked in a pivoted-down limit position and in a pivoted-up limit position, for the purpose of secure locking in the respective limit position a locking shaft which can be rotated by means of a handle (78) counter to the force of at least one restoring spring (91) is mounted on the telescopic supports (9), on which locking shaft at least one bolt (82) is fastened which, in the respective limit position of the telescopic supports, engages, under the effect of the restoring spring force, with a hook (84; 85) behind a projection (69; 70) fixed to the frame, whilst the pivoting up of the telescopic supports (9) is promoted by the force of at least one relief spring (66). <IMAGE>
