  • the assembly comprises a tube 40 within the outermost telescope tube 4 having a base ring 40".
  • a hydraulic cylinder 62 concentric with the tube 40, is attached to and extends upwardly from the ring 40".
  • the hydraulic cylinder 62 is provided with a piston 63 therein having a piston rod 64, which slidably passes through the middle opening 65 of the ring 40".
  • the piston rod 64 is hollow and passes through and is securely fastened to a base ring 4" of the tube 4.
  • the piston rod 64 is also fastened to and communicates with a feed pipe 66, for supplying oil under pressure into the space 67 above the piston 63, by means of which the cylinder 62 is raised.
  • the tube 40 also rises by virtue of the base ring 40" connecting the elements 40 and 62 for mutual motion therebetween.
  • a chain 49' is provided and is fastened at one end to a member 68 fastened to the upper end of the telescope tube 4 and at the other end to the base ring 39" of the third telescope tube 39, the chain 49' passing over a wheel 47 mounted at the upper end of the second telescope tube 40.
  • raising of the telescope tube 40 causes the third telescope tube 39 to rise.
  • a second chain 48' which is fastened at one end to a member 69 at the upper end of the second telescope tube 40 and at the other end to the base ring 38" of the fourth telescope tube 38, extends over a wheel 48 mounted at the upper end of the third telescope tube 39. Through this second chain 48, the rising movement of the third telescope tube 39 is transferred to the fourth telescope tube 38.
  • a third chain 47' which is fastened at one end to a member 70 at the upper end of the third telescope tube 39 and at the other end to the base ring 37" of the fifth telescope tube 37, extends over a wheel 47 mounted at the upper end of the fourth telescope tube 38.
  • the rising movement of the fourth telescope tube 38 is transferred to the fifth telescope tube 37.
  • guide rings 4', 40', 39 and 38' respectively, each said ring accommodating the inner tube adjacent thereto in a sliding fit. The manner in which these rings are fastened to the tubes is shown in detail in FIG. 7, with reference to the ring 39'.
  • the upper ends of the telescope tubes 4, 40, 39, 38 have bolts 71 welded to their outer surfaces. These bolts pass through boreholes 72 provided in the guide rings 4', 40', 39', and 38' and allow the clamping of the guide rings to the tubes by means of nuts'73 threadedly engageable with the bolts 71.
  • a similar technique is used to fasten the base rings 4", 40", 39", 38" and 37" to the telescope tubes 4, 40, 39, 38 and 37 respectively whereby the screw bolts 74 (see FIG. 8) are welded to the inner surface of each tube and pass through boreholes 75 in the base rings 4", 40", 39", 38" and 37", to which they are fastened by means of nuts 76, screwed onto the bolts 74.
  • Each base ring 40", 39", 38” and 37 protrudes radially outwards to a small extent from the respective telescope tube 40, 39, 38 and 37 and therefore also serves as a guide ring for the respective adjacent outer tube.
  • the cylinder 62 By locating the cylinder 62 inside the tubes an extremely safe and compact arrangement is provided, which has the further merit of simplicity and structural robustness. Also, the fluid transmission to the interior of the cylinder is greatly facilitated by arranging the piston rod 64 to be fixed to the base ring 4" of the outer tube 4 and to be hollow, whereby the fluid may be introduced therethrough without the need for external piping.
