Abstract (en)
[origin: WO2017151325A1] An actuator assembly for operating a tubular running device includes a housing assembly coupled to the outer cage. The housing assembly is movable relative to the inner mandrel. An upper fluid chamber is disposed between the housing assembly and the inner mandrel, and a lower fluid chamber is disposed between the housing assembly and the inner mandrel. Fluid pumped through an upper pressure port into the upper chamber moves the housing assembly in a first direction thereby causing the gripping apparatus to engage the tubular, and fluid pumped through a lower pressure port into the lower fluid chamber moves the housing assembly in a second direction thereby causing the gripping apparatus to disengage the tubular.
