Narrow-aisle truck, comprising: - a vehicle body with a longitudinal direction (y) and a width direction (x); - wheels (314a, 314b, 318) assigned to the vehicle body which are arranged in two axes running in the width direction (x) of the narrow-aisle truck and adapted to drive and steer the narrow-aisle truck when travelling on a driving surface; - a drive system that is adapted to exert an acceleration torque on at least one of the wheels (314a, 314b, 318); - a mast extending substantially vertically between the two axes with respect to the longitudinal direction (y) of the narrow-aisle truck; wherein the mast, by means of a bearing arrangement, is movably mounted relative to the vehicle body with respect to at least one degree of freedom of movement; - at least one detection unit (22, 24a-24d, 26) that is adapted to detect at least one status parameter of the narrow-aisle truck and/or its environment and to output corresponding data; - at least one actuator that is adapted to effect a movement of the mast relative to the vehicle body according to the at least one degree of freedom; and - a control unit that is operationally coupled to the at least one detection unit (22, 24a-24d, 26) and the at least one actuator and for this purpose is adapted: - to determine an actual status of the narrow-aisle truck on the basis of the at least one status parameter detected by the at least one detection unit (22, 24a-24d, 26); - to detect an effect of an actuation of the at least one actuator on the actual status; and - to control the at least one actuator in such a way that a difference between the determined actual status and a predefined target status is reduced, characterised in that by means of the bearing arrangement, the mast is floatingly mounted with respect to a bearing plane which extends substantially vertically (z) and in the width direction (x) of the narrow-aisle truck, a further bearing arrangement being also provided that is adapted to enable the mast to be swivelled about an axis which extends perpendicularly to the bearing plane, which swivelling can be driven by a correspondingly arranged actuator, the further bearing arrangement and the actuator for swivelling the mast being arranged on opposite sides of the mast with respect to the width direction (x) of the narrow-aisle truck. - a vehicle body with a longitudinal direction (y) and a width direction (x); - wheels (314a, 314b, 318) assigned to the vehicle body which are arranged in two axes running in the width direction (x) of the narrow-aisle truck and adapted to drive and steer the narrow-aisle truck when travelling on a driving surface; - a drive system that is adapted to exert an acceleration torque on at least one of the wheels (314a, 314b, 318); - a mast extending substantially vertically between the two axes with respect to the longitudinal direction (y) of the narrow-aisle truck; - at least one detection unit (22, 24a-24d, 26) that is adapted to detect at least one status parameter of the narrow-aisle truck and/or its environment and to output corresponding data; - at least one actuator that is adapted to effect a movement of the mast relative to the vehicle body according to the at least one degree of freedom; and - a control unit that is operationally coupled to the at least one detection unit (22, 24a-24d, 26) and the at least one actuator and for this purpose is adapted: - to determine an actual status of the narrow-aisle truck on the basis of the at least one status parameter detected by the at least one detection unit (22, 24a-24d, 26); - to detect an effect of an actuation of the at least one actuator on the actual status; and - to control the at least one actuator in such a way that a difference between the determined actual status and a predefined target status is reduced, - to determine an actual status of the narrow-aisle truck on the basis of the at least one status parameter detected by the at least one detection unit (22, 24a-24d, 26); - to detect an effect of an actuation of the at least one actuator on the actual status; and - to control the at least one actuator in such a way that a difference between the determined actual status and a predefined target status is reduced, by means of the bearing arrangement, the mast is floatingly mounted with respect to a bearing plane which extends substantially vertically (z) and in the width direction (x) of the narrow-aisle truck, a further bearing arrangement being also provided that is adapted to enable the mast to be swivelled about an axis which extends perpendicularly to the bearing plane, which swivelling can be driven by a correspondingly arranged actuator, the further bearing arrangement and the actuator for swivelling the mast being arranged on opposite sides of the mast with respect to the width direction (x) of the narrow-aisle truck.
