  "textContent": "The invention relates to a hook-lift truck for transporting interchangeable containers (8), comprising - two cantilever arms (14) delimiting a space between them, pivotable about a rear pivot axis (16) that is normally horizontal and runs in the transverse direction of the vehicle, which have telescopically extendable and retractable end elements (12), to which support elements (10) in the form of support chains or support cables for an interchangeable container (8) accommodated in the space between the cantilever arms (14) and suspended from the cantilever arms (14) by means of the support elements (10) are attached, wherein the cantilever arms (14) are pivotable backwards and forwards about the pivot axis (16) in a container exchange operating mode of the hook-lift truck in order to set down an interchangeable container (8) standing on the hook-lift truck beyond the vehicle rear onto the ground or to pick up an interchangeable container (8) set down on the ground beyond the vehicle rear onto the hook-lift truck, - at least one tipping hook (22) pivotable between an inactive position and a catch position about a flap axis (26) parallel, preferably coaxial, to the rear pivot axis (16) of the cantilever arms, which is positioned in its catch position in a tipping operating mode of the hook-lift truck - and is arranged to engage a rear tipping bearing pin (28) of an interchangeable container (8) suspended from the end elements (12) of the cantilever arms (14) and moved into a tipping position by pivoting the cantilever arms (14) backwards, and thus to force the interchangeable container (8) into the tipping position with continued pivoting of the cantilever arms (14), - at least one hydraulic pivot cylinder (18) as pivot drive means for the cantilever arms (14), - hydraulic telescoping cylinders for telescopically extending and retracting the end elements (12) of the cantilever arms (14), wherein the telescoping cylinders are connected to a hydraulic circuit associated with them for supply with hydraulic fluid, - drive means for pivoting the tipping hook (22) about the flap axis (26), - a control device (24) for controlling the at least one hydraulic pivot cylinder (18), the hydraulic telescoping cylinders and the drive means for pivoting the tipping hook (22), and - an operating device to be actuated by an operator for setting the desired operating mode of the hook-lift truck and for issuing control commands to the control device (24), characterized in that in the hydraulic circuit associated with the telescoping cylinders a pressure limiting device, preferably pressure limiting valve arrangement, to be activated by means of the control device (24) is provided, which is arranged to limit the maximum hydraulic pressure in the telescoping cylinders to a value in the tipping operating mode of the hook-lift truck that is reduced compared to the value of the maximum pressure in the telescoping cylinders achievable in the container exchange operating mode.",
