- an object of the invention is to provide an installation of the aforementioned type, the design of which allows easy intervention on the machine in a safe manner without harming productivity.
- the subject of the invention is an installation for maintaining a rolling machine with two or three wheels with a view to an intervention on said machine, said installation comprising an elongated plate developing longitudinally from one end towards the opposite end and having two opposite faces and a first holding device having at least two jaws capable of forming a vice to allow gripping in a vice of at least one wheel of the machine, characterized in that the installation comprises a second holding device, in that the first and second holding devices are arranged one, at one of the ends, the other, at the other of the ends of the so-called top face of the plate , in that the second holding device is removably mounted on the plate, in that the second holding device comprises a first jaw and a second jaw that can be positioned facing each other in a direction transverse to a longitudinal axis of the plate, in that the first and second jaws each
- a second holding device capable of ensuring a vice grip of the rear wheel of the machine makes it possible to easily lift the front of the machine.
- THE removable mounting of the second holding device on the plate makes it possible not to interfere with the access of the machine to the plate.
- the design of the jaws of the second holding device allows quick blocking so as not to affect productivity.
- the screw/nut assembly is an irreversible assembly.
- pressing on the mobile part of the first jaw does not generate any rotation of the screw.
- the angle of friction between the nut and the screw is greater than the helix angle of the screw.
- the plate is provided with through holes and the fixed parts of the first jaw and the second jaw of the second holding device are each equipped with at least two lugs each insertable in a hole of said plate for maintaining the stationary state of said fixed part.
- the fixing of the fixed parts of the jaws to the plate by simple tabs allows this operation to be carried out simply and without tools.

- a similar U-hook could have been obtained using the lug alone.
- the hooks of a bit are open towards the longitudinal edge of the plate closest to the bit.
- the U-shaped hooks tend to move away from each other by sinking deeper into the through holes of the plate in the coupled state of the fixed parts of the first and second jaws to the plate 2 when the first and second jaws are biased in the direction of separation from each other, in particular when the moving parts of said jaws are biased in the direction of separation from one another, so that any risk accidental stalling of said fixed parts of the first and second jaws 61 and 62 of the plate 2 is prevented.
- the first holding device 4 is positioned on the face side 33 of the top of the plate 2 at one end, for example the end 31 of the plate 2.
- the machine 15 such as a motorcycle is introduced on the plate 2 by the opposite end 32 of the plate 2 and is brought to the first holding device 4, so that the front wheel of the machine is gripped in a vice at the level of the first holding device 4 between the jaws 41 and 42 of the first holding device 4.
- the second holding device 5 can then be put in place at the opposite end 32 of the plate 2.
- the fixed part 622 of the second jaw 62 is coupled using the lugs 12 in the holes 11 of the plate 2, and the movable part 621 of the second jaw 62 is moved by hand to slide relative to the fixed part 622, until it comes to bear against a side of the rear wheel of the machine 15.
- each member 10 of radial immobilization associated with a bearing 6221 of the fixed part 622 is screwed to bear on a bevel of one of the guide pins 82 of the second jaw 62 introduced into said bearing 6221 .
- the fixed part 612 of the first jaw 61 of the second holding device 5 is similar to that of the second jaw 62, fixed to the plate 2.
- the movable part 611 of the first jaw 61 is guided in sliding movement by the axes 81 guide which are mounted movable to slide in the bearings 6121 of the fixed part 612 of the first jaw 61 .
- the screw 71 which is one end, coupled in a free rotational manner to the movable part 611 of the first jaw 61 and which is screwed into the nut 72 of the fixed part 612 of the first jaw 61 is driven in rotation to allow a separation of the movable part 611 of the first jaw 61 of the fixed part 612 of the first jaw 61 until the movable part 611 of the first jaw 61 comes into abutment on the side of the rear wheel of the machine 15 opposite to that against which the mobile part of the second jaw is supported.
