If the surface is slanted or uneven, on the separate incline- adjustable lower pedestal of the hydraulic sheeting support 50, previously affixed through bores 52 if necessary, the lower fixed pedestal 2 is placed under the subject element of support or elevation.

  • the hydraulic sheeting support functions as an independent post that can accept compression forces. Likewise, it can serve as a hydraulic jack where the element of elevation is substantially higher in respect to the anchorage from which it is possible to use an elevation force. Because of the large range of height regulation, the use of the hydraulic sheeting support is vastly suitable in situations where loads are individually elevated to relatively different heights.

Abstract

L'invention porte sur une construction améliorée de support de revêtement hydraulique qui comprend : un vérin hydraulique (1) fixé par un boulon de carter de vérin (4) sur le filetage (17) d'un cylindre principal (15) et fixé de manière analogue sur un cylindre opérationnel (18) disposé à l'intérieur du cylindre principal (15) par un boulon qui permet d'attacher le cylindre opérationnel au support de revêtement hydraulique (13). Au-dessus du boulon de sécurité (20) est placée une échelle millimétrique (24) qui, combinée à l'échelle centimétrique (43), indique la hauteur exacte de support du support de revêtement hydraulique. Un verrou situé sur le cylindre supérieur du support de revêtement hydraulique empêche que le cylindre supérieur (40) ne sorte accidentellement du cylindre opérationnel (18). L'option autorisant l'installation de piédestaux supérieurs interchangeables (47) permet d'élever (et de soutenir) des charges de formes différentes, et des piédestaux inférieurs séparés à inclinaison réglable permettent l'installation du support de revêtement hydraulique (50) sur des surfaces inclinées et irrégulières. L'invention élimine tout risque de torsion ou de rupture du support et la fixation de l'écrou de sécurité (23) sur le bord supérieur du cylindre principal en acier (15) permet d'éviter une exposition prolongée du vérin hydraulique (1) aux effets des charges soutenues.
