Designed to combine simplicity with smart bolting technology, Enerpac announced the ETW-Series electric torque wrenches for controlled bolting applications in offshore wind projects that require speed, precision and traceability.
From their foundations to their nacelles, wind towers are bolted together. These bolts are subjected to stress originating from several causes including vibration, fatigue cycles (caused by the constant rocking back and forth of the tower), and inclement weather. Consequently, applying a suitable controlled bolting method to achieve the required preload of the fasteners is necessary for the construction and maintenance of any wind tower.
According to Enerpac, the ETW torque wrench provides fast, accurate and safe fastening through the creation of automatic presets. Operated with an interactive 7 inch touch-screen, the user inputs the desired torque, or torque and angle specifications, into the control box. These are then applied to the number of fasteners required for the job. For simpler jobs, torque values may be input directly into the gear control panel of the wrench, which also enables the operator to monitor and manage the fastening process, to ensure that each fastening is made to specification.
In addition to the ETW, Enerpac also produces manual and pneumatic torque wrenches, as well as hydraulic torque and bolt tension systems, for offshore wind bolting applications.
