Tackling machine comprises supporting frame structure (1) with shape of a parallelepiped and detachable connecting devices interconnect its elements. It is placed on ground (2). The longitudinal guide (6) has forked end and is mounted to the structure (1) through the forward end (61). The forked end (62) of the longitudinal guide goes outside the structure (1). At least one metal rod (8) whose upper end (81) protrudes above the parallelepiped, and carry at least one tensioner (9), connected to the forked end (62). The drive unit (10) is mounted to the fork-shaped longitudinal guide and has a working area arranged outside the structure (1). The tackling dummy (11) is attached to the carrier (12) by a detachable connecting device (13). ## Claims ### Claim 1 A tackling machine comprising a supporting frame structure comprising a plurality of load-bearing upper girder elements connected with each other and with columns, and a longitudinal guide is mounted lengthwise centrally on the frame structure to which a drive unit is mounted with a tackling dummy suspended thereto on a carrier, wherein the supporting frame structure has the shape of a parallelepiped, comprising all the elements forming its outline, comprising upper girder elements, columns and lower girder elements, and it is placed on a ground surface, wherein the longitudinal guide is a fork-shaped tubular element and is mounted to the supporting frame structure by its the forward end abutting bearing elements and a forked end of the fork-shaped tubular element is located outside the supporting frame structure, which includes also fixed to it at least one metal rod comprising an upper end protruding above the parallelepiped, and at least one tensioner is fixed thereto, connected to the forked end of the fork-shaped tubular element, wherein the drive unit is mounted to the fork-shaped tubular element and has a working area along the fork-shaped tubular element, arranged outside the supporting frame structure, and the tackling dummy is attached to the carrier by a detachable connecting device, further wherein the drive unit comprises a carriage comprising wheels, which is disposed inside the fork-shaped tubular element which comprises a slit along its entire length, wherein the carrier of the tackling dummy is situated. ### Claim 2 (depends on 1) A tackling machine according to claim 1, characterized in that the columns, the upper and lower girder elements of the support frame structure are interconnected by detachable connecting devices. ### Claim 3 (depends on 1) A tackling machine according to claim 1, characterized in that the tensioner is made of a chain. ### Claim 4 (depends on 1) A tackling machine according to claim 1, characterized in that the tensioner is made of wire rope. ### Claim 5 (depends on 1) A tackling machine according to claim 1, characterized in that the carriage is driven by an electric motor. ### Claim 6 (depends on 1) A tackling machine according to claim 1, characterized in that the carriage is driven by compressed air. ### Claim 7 (depends on 1) A tackling machine according claim 1, characterized in that the drive unit is a container for compressed air on a side of which there is a supply mouthpiece, wherein the fork-shaped tubular element is formed by a pair of S-shaped tubes, positioned specularly to one another, and the container for compressed air is secured by at least two hoops attached to each tube of the pair of tubes, and is secured by at least one additional hoop, to which the carrier of the tackling dummy is suspended. ### Claim 8 (depends on 7) A tackling machine according to claim 7, characterized in that the attachment of the at least two hoops to each tube of the pair of tubes is accomplished by a climbing roller). ### Claim 9 (depends on 7) A tackling machine according to claim 7, characterized in that rigging devices are utilized for the attachment of the at least two hoops to each tube of the pair of tubes. ### Claim 10 (depends on 1) A tackling machine according to claim 1, characterized in that the detachable connecting device takes the form of a flexible plate, passing through openings of a double cap which includes axially fixed in the upper end of the tackling dummy a tubular connecting element with a diametrical opening on which a cap is arranged with a suspension element and with two diametrically opposite openings corresponding to the diametrical opening of the tubular connecting element and the flexible plate is placed in the openings of the cap and the diametrical opening of the tubular connecting element. ### Claim 11 (depends on 1) A tackling machine according to claim 1, characterized in that the carrier has a fixed connection to a carriage and a cap. ### Claim 12 (depends on 1) A tackling machine according to claim 1, characterized in that the detachable connecting device is of the type of flexible link between a suspension element axially fixed at the upper end of the tackling dummy and the carrier. ### Claim 13 (depends on 1) A tackling machine according to claim 1, characterized in that the tackling dummy is made of polystyrene foam.
