Abstract
The heads of a pressure vessel are normally attached to the vessel body by studs and nuts arranged in a bolting circle. Each nut is engaged by a wrench, the handle of which is radially outwardly disposed relative to the bolting circle. The outer ends of all the wrench handles have elongated openings slidably engaged by pivot pins that pivotally connect the handles to the ends of turn-buckles, so that the wrenches may all work concurrently. Preferably, the wrenches are ratchet-type socket wrenches. Hydraulic cylinders are attached to some of the wrench handles and impart a back-and-forth movement to the latter for screwing the nuts at a precisely-measured and uniform torque and all simultaneously. The arrangement can be modified to suit different numbers of studs and/or diameters of the bolting circle.
