Hydraulic Elliptical Bolt Tensioner, 38 mm Bolt, 57 mm A/F - Enerpac FTE7511S

The FTE7511S elliptical bolt tensioner tensions foundation bolts of 38 mm diameter hydraulically and under strain control. Its elliptical shape reaches joints with limited access without reducing tensioning capacity.

Benefits

• Elliptical form for use in confined spaces without loss of performance
• Uses the existing hex nut as a reaction point to eliminate thread fit misalignment
• Nut rundown with a Tommy bar, no offset rundown gear required
• Max. stroke indicator protects against over-stroking and extends service life
• Auto-retract piston for fast operation
• Zinc coating for high corrosion resistance
• Compatible with Williams, Dyson and Macalloy studs
