10 handles 10, and a platform 15.

ESCAMOBILE frame 1 has four vertical tubes 11, 12, 13, 14 and two inclined tubes

16 and 17. The tubes 11 and 14 are intended to receive the corresponding ends of the element 6 and the tubes 12 and 13, the corresponding ends of the element 7, while in the inclined tubes one engages

, e the corresponding ends of the element 5 which constitutes an access ladder having steps 19:

On each of the elements 6 and 7 of one of the ESCAMOBILE models are welded horizontal tabular elements 20 open at their two ends and intended to receive the platform 15. The steps 19 rest on tubular elements 21 falling opposite tubular elements 20 so as to be able to engage pins 22 passing through said elements 21 and penetrating into said elements

_7Q 20 and forming the assembly members of element 5 on elements 6 and 7.

In each of the elements 6 and 7 of ÎΕSCAOTOMOBELE are slidably mounted two vertical rods 24 joined at their upper part by a tube 25 constituting a railing, said rods 24 being pierced with a series of holes 26 in which pins 27 can be selectively engaged who. passing through a hole corresponding to the upper ends of elements 6 and 7 make it possible to wedge the

₂₅ guardrail at any desired height.

The wheels 2 are mounted idler each at the end of a half-axle 29 of square section, each half-axle being slidably mounted in a corresponding tubular element 30 of the frame in metallic structure. This arrangement allows the wheels 2 to move apart from one another so as to give the ESCAOTOMOBILE scaffolding a good foundation. „ _N Indeed if the user works at a relatively high height, it is preferable not to risk tipping said ESCAOTOMOBILE scaffolding. to move the wheels 2 apart as much as possible.

The wheels 3 and 4 1 ^{"ESCAOTOMOBILE} are each mounted idle on ^the end of an axle? 1 which is erected a vertical shaft journalled in a bearing 32 of the frame 1 the upper end of said shaft

-, _< - has a yoke 34 in which is articulated, around a horizontal axis 35, a rod of square section

36 engaged in a tube of corresponding section 37 terminated at its free end, by the operating member 9 presenting the handles 10.

On the tube 37, is articulated a bar 39 in the shape of a U whose branches are intended to penetrate, each, in one of the tubes 25 constituting the guardrail of 1ΕSCAOTOMOBILE. The axle 31 carries two portable players 40, allowing blocking or unblocking, each of these two portable players being arranged in the vicinity of one of the ends of said axle 31 and being intended to cooperate with the wheel 3. and the other with wheel 4

To mount the ESCAMOBILE scaffolding according to one of the variants of the invention, the procedure is carried out as follows: the lower end of the element 6 is engaged in the tubes 1 1 and 14. then the element 7 in the tubes 12 and 13, the element 5 being engaged by its lower ends in the inclined tubes 16 and 17. the pins 27 are then engaged in the tubes 21 and 20. the platform 15 is placed on the tubes 20 at the chosen height , the rods 24 are slid and engaged in the holes 26 of the pins 27 to wedge the guardrail at a suitable height finally the branches of the U-shaped bar 39 are engaged in the tubes 25

The user being mounted in the nacelle, on the platform 15 he can, at will, advance,

10 turn or move back the convertible ESCAMOBILE Indeed, to advance said ESCAOTOMOBILE scaffolding. it will suffice, by acting on the handles 10 to give them a back and forth movement. we understand that when we act on one of the handles 10. for example by rotating it \ ers the front. the corresponding wheel will describe the same movement but cannot go back because the pawl 40 by cooperating with the teeth 41 will oppose it then by acting on the other handle 10. by making it

15 swivel forwards, the other corresponding wheel will be described the same movement without the first wheel having moved back
