An adjustable height beam support (11, 12) is fastened to a frame (1) mounted on wheels (6 to 9); a vertically moveable sliding carriage (14) carries a rotatably mounted pressure beam (13). By means of double-acting hydraulic cylinders, two pressure arms (13a, 13b) slidingly mounted on the pressure beam (13) can press outwards against the container side walls or--with the pressure beam set vertically--against the bottom and the top of the container. Deformations of the container walls can, in this manner, be corrected without large expenditure of time and money. A mobile hydraulic cylinder (23) can be applied to both the frame (1) for moving the equipment into the container and to the pressure beam (13).

1. Equipment for the repair of dents or bulges in containers, comprising: wheel supported frame means; a vertically upright support column fixedly mounted on said frame means; first carriage means reciprocally mounted on said support column between upper and lower limits; elongated beam means
1. Equipment for the repair of dents or bulges in containers, comprising: wheel supported frame means; a vertically upright support column fixedly mounted on said frame means; first carriage means reciprocally mounted on said support column between upper and lower limits; elongated beam means and first mounting means for mounting said beam means on said first carriage means, said mounting means including means defining a horizontal axis intermediate the ends of said beam means; second and third carriage means reciprocally mounted on said beam means, one each on opposite sides of said horizontal axis, each said second and third carriage means having a container engaging tool thereon; drive means for driving said second and third carriage means reciprocally on said beam means; a cylinder means having a movable member thereon and second mounting means for mounting said cylinder means to said support column; connecting means for connecting said movable member on said cylinder means to said first carriage means so that said first carriage means will travel up and down said support column in response to a movement of said movable member; whereby said second and third carriage means and said tool thereon can be moved by said drive means into simultaneous engagement with spaced surface sections on said container, such as spaced sidewall sections or spaced top and bottom wall sections at vertical locations determined by the position of said first carriage means on said support column. 2. Equipment according to claim 1, wherein said cylinder means consists of an internal cylinder and an external cylinder encircling said internal cylinder and defining said movable member, and a vertically stationary piston slidably located in said internal cylinder, and wherein said connecting means includes two chains for connecting said first carriage means to said external cylinder and a chain idler unit which is fixedly attached to the upper end of said external cylinder, whereby a displacement of the external cylinder between its lower and upper position relative to said internal cylinder raises and lowers said beam means with respect to said carriage support and a displacement of the internal cylinder relative to said piston with said external cylinder in its lower position raises and lowers said beam means with respect to said support column by a further amount. 3. Equipment according to claim 1, wherein said horizontal axis divides said beam means into two arms, each of said arms having a front-mounted support rail in which a mobile hydraulic cylinder can be inserted and displaced to any given point on said beam means, and wherein said mobile hydraulic cylinder is provided with rollers, permitting the latter to hang releasably in said support rails, each of the two said support rails having an upright U-profile, which is matched to the size of said rollers. 4. Equipment according to claim 3, wherein a sliding piece, which is freely displaceable on said beam means, is located in the central region of the latter serving as a holding device for said mobile hydraulic cylinder, said sliding piece also having a support rail designed as a U-profile. 5. Equipment according to claim 1, wherein for adjusting the working position of said beam means when in a normally horizontally aligned position, a drive is provided consisting of a hydraulic cylinder located at the lower part of said first carriage means, which hydraulic cylinder is connected via a lever to a pivot pin on said beam means. 6. Equipment according to claim 1, wherein on the lower part of said frame means, at least two freely rotatable rollers are mounted on pivoting arms, being pivotable about a horizontal axis and coupled to a drive in such a way that said rollers can be lowered onto a container bottom by a first action of said drive and, on further action of said drive, can lift said frame means sufficiently far for the latter to be displaced with said wheels onto the bottom of the container. 7. Equipment according to claim 6, wherein said frame means is provided with two rollers mounted on pivoting arms on each of two mutually opposite sides. 8. Equipment according to claim 7, wherein each pivoting arm has a toothed segment at an end opposite to said roller, which toothed segment engages with a toothed rack which can be moved forwards and backwards and which is coupled to said drive, and wherein said toothed rack having teeth which are directed downwards at one of its end sections and upwards at the opposite end section, with the objective of pivoting said pivoting arms, engaging via toothed segments with said two end sections, in opposite rotational directions when said drive is actuated. 9. Equipment according to claim 8, wherein said pivoting arms located at mutually opposite sides of said frame means are of different lengths and said toothed rack has at least one offset. 10. Equipment according to claim 6, wherein said drive is a mobile hydraulic cylinder which, in its working position on said frame means, is inserted between two buffers so as to be freely removable in such a way that this hydraulic cylinder can also be applied at other locations on the frame on correspondingly located holding devices. 11. Equipment according to claim 10, wherein said mobile hydraulic cylinder has a side protrusion in such a way that the upper part of said hydraulic cylinder can be put under load with said protrusion between two flanges of a U-profile for the purpose of straightening the latter. 12. Equipment according to claim 1, wherein said horizontal axis divides said beam means into two arms, wherein on each arm at least one acceptance part for fastening a buffer, vertically insertable on said arm in its horizontal position, is provided for the purpose of straightening bent bottom profiles.
