Description

Both the customer and industry have highlighted the need to apply accurate bolt loading in a controlled and safe manner. Boltite Bolt Tensioning system offers the quickest, safest, most accurate means of applying a specified residual load to stud bolts. Boltite AT Series Bolt Tension Features: - AT series tensioners with innovative spring return reduces operator fatigue and reduces operation time, are a modular tool which can use various adaptor kits allowing them to be used on multiple bolt sizes. - Unique design provides the optimum bolt tensioner Modern computer-aided design techniques Finite element stress analysis Photo-elastic modeling Strain Gauging and cyclic testing Boltite AT Series - 1.Overstroke Eliminator ① A relief valve has been incorporated into the piston to prevent overstroking, thus eliminating seal damage and improving operator safety. When the maximum stroke is exceeded, the overstroke relief valve bleeds of the water-based hydraulic fluid safely within the tool. 2.Rapid Power Return Stroke ② Automatic, spring-assisted piston retraction assists in reducing the duration of tensioning programmers, improved time saving. 3.Misalignment Compensation ③ The unique floating piston design allows a 30 tilt (in any direction) without loss of load, preventing piston seizure or damage to the cylinder bore. 4.Piston Stroke Indicator ④ The integral piston stroke indicator allows piston stroke to be viewed, measured and controlled. 5.Seals ⑤ Low friction, anti-roll/non-spiraling seals and rigid back-up rings are incorporated within a unique piston/cylinder design for improved life and reliability.
