1. An autonomously-guided industrial truck, comprising:
a vehicle frame for connection to a load unit or load bearing means, the vehicle frame defining a vehicle contour in horizontal cross-sections, the vehicle frame comprising three horizontal structural levels, arranged one above the other in a vertical direction, the three horizontal structural levels comprising:
a lower structural level in which a base plate is arranged, the base plate receiving a lower section of at least two scanner units and receiving a drive wheel of the industrial truck, the lower structural level having a first contour;
an upper structural level with a covering, the upper structural level having a second contour; and
a middle structural level comprising a frame structure for connecting the lower structural level and the upper structural level, wherein the middle structural level includes a region formed between the first contour and the second contour;
at least one drive wheel assigned to the vehicle frame to stand below the vehicle frame on a driving surface; and
wherein the at least two scanner units are arranged within the vehicle contour and in the middle structural level, extending vertically upwards from the base plate such that a scanning plane of the at least two scanner units lie vertically in a region of the middle structural level; and
wherein the at least two scanner units are arranged such that the scanning plane is completely covered in a range of three hundred sixty degrees (360°) along a horizontal direction relative to the industrial truck by the at least two scanner units.
