摘要:
A method of handling a generally cylindrical conduit includes positioning a lift cylinder within the generally cylindrical conduit. The lift cylinder includes an inflatable bag, an inflation port, and an attachment point. The method also includes connecting a fluid source to the inflation port, inflating the inflatable bag with the fluid source such that an outer surface of the inflatable bag engages an inner surface of the generally cylindrical conduit, connecting a winch to the attachment point, and moving the lift cylinder and the generally cylindrical conduit with the winch.
