In a crawler-type track, an endless flexible belt is stretched over a stator which includes fluid-receiving pressure-tight cells and is formed with a central fluid collecting tank connected to a revolving pump. The cells of the stator are supplied with pressure fluid via the channels or passages formed in the stator. The belt is radially spaced from the stator so that a gap, formed therebetween, is filled with pressure fluid. The belt is provided with an inner slide layer also formed with fluid-receiving cells. The fluid-containing system is enclosed in a pressure-tight circuit.

A fluid-operated transporting crawler-type track, comprising a bending-resistant and torsion-resistant stator; an endless, flexible and a fluid-and-pressure-tight belt stretched over an entire width of said stator, said stator including fluid-receiving and fluid-transmitting pressure-tight cells and passages uniformly distributed over the width of said stator, said passages connecting said cells with a bottom-side slide surface of said stator, said belt and said stator being spaced from each other to form there-between a gap which admits the fluid, said stator being formed with a collecting tank centrally positioned in said stator and with an inlet opening which connects said tank with said gap; side walls pressure-tight enclosing said stator at the sides thereof and being of the length smaller than the thickness of said belt, said belt having a slide layer facing said stator and having an outer surface facing said stator, formed of hydrostatic cells, said hydrostatic cells being open towards said stator and having elastic cell walls; non-rigid reinforcements inserted in said belt and connected with lateral support elements extended outwardly from said belt and forming a roller chain supported in a side wall of said stator; wheel disks engaged with said roller chain so as to rotate said belt and positioned outside of said stator; and a drive aggregate for driving said disks, said belt being at two sides thereof fluid-tightly connected to said side walls.
