    摘要： Embodiments disclosed herein generally relate to a system and method for tensioning a bolt. The bolt tensioning system may be used with variable length connection members, for example studs, in any one or more of the drilling, subsea, and process industries to couple a first member to a second member. The bolt tensioning system may remain coupled to the first member and the second member, while applying tension to all of the bolts at the same time, rather than having to torque or tension each bolt individually. The bolt system may accurately and uniformly tension all bolts in a single operation to provide reliable connections.

    摘要： Embodiments of the invention relate to apparatus and methods for a secondary safety device for use on elevators utilized to move casing, tubing, sucker rods, or other circular tools or members in the oil and gas industry. In one embodiment, a secondary latch lock mechanism for an elevator having a primary safety latch is provided. The secondary latch lock mechanism comprises a base portion that is fixed to a body of the elevator, and a handle movably fixed to the base portion and a first gear device by a biasing member, wherein the handle is movable to a first position proximate to the primary safety latch and a second position that is spaced away from the primary safety latch.
