Description

Our tensioners have quality designed in with standard features that enhance durability and efficiency to get the job done faster and safer:

Quality Means Lower Life-Cycle Costs:

  • Achieves 90% proof load requirement for ISO 898 Grade 10.9 bolts
  • Fully enclosed load cell eliminates debris in piston retraction mechanism
  • Auto-Engaging Geared Nut Rotator
  • Self-energizing, long life seals

Enhanced Usability:

  • Piston stroke limit indication
  • High pressure swivel coupling (swivel is optional on WSS & WSL)
  • 19,580 psi  (1,350 bar maximum operating pressure)
  • Automatic piston retraction mechanism

Designed with Safety in Mind:

  • Overstroke prevention for safe operation
  • Anti-slip grip surface
  • Tool lifting-strap as standard

WDD UP TOWER WIND TENSIONERS
