Abstract: A mobile storage container (1) has a storage space (3) which is delimited by a peripheral wall (5) and by a bottom (6) and a lid (7). The storage container (1) is transportable in a horizontal position and with approximately horizontally aligned longitudinal axis (4) on roads and has in the area of the bottom (6) support legs (8) for installation at construction sites or the like with the longitudinal axis (4) vertically aligned. Each support leg (8) has a support foot (9) which is extendable radially relative to the longitudinal axis (4) past the outer contour of the peripheral wall (5).

Abstract: An excavating device has conical milling tools each having a longitudinal center axis. At least one motor is provided for rotatingly driving the milling tools about their longitudinal center axis. The milling tools each have a mantle surface. The mantle surfaces are positioned at one circumferential point adjacent to one another at a minimum spacing defining a working play between the milling tools such that the mantle surfaces form a continuous working plane. The longitudinal center axis of the milling tools are positioned angularly to one another and to a vertical axis extending between the milling tools. Each longitudinal center axis is positioned at an angle of between 50.degree. and 70.degree. to the vertical axis. Each one of the longitudinal center axes is positioned at an angle of less than 90.degree. relative to the advancing direction of the excavating device.
