Abstract

La présente invention concerne un équipement destiné à un derrick et comprenant deux, ou davantage, ensembles hydrauliques piston-cylindre (10, 11) servant à hisser et à abaisser un joug (8) qui se déplace sur des rails de guidage (7) dans le derrick lui-même, et un système hydraulique (30) servant au fonctionnement des ensembles piston-cylindre, ce système ayant différents modes de fonctionnement: hissage ou descente normal(e) du joug (i), utilisation de la zone différentielle du piston (21) pour abaisser ou hisser rapidement le joug et, éventuellement, une combinaison de ce qui précède, avec un supplément de pression fourni par les accumulateurs (39).
