Shoulder Eye Bolt Failure During Equipment Lift


A fracturing (“frac”)/ wellhead assembly was lifted approximately half an inch to adjust a support (levelling jack) stand. The lift was conducted using the horizontally - attached shouldered eyebolts on the equipment. The orientation of the eyebolts required an angular lift. The lift took place and the eyebolt shanks sheared off. The wellhead equipment was secured and no other damage occurred.
