Superbolt multi-jackbolt tensioners (MJTs) өндөр чанарын гангаар хийгдсэн, өөр дээрээ давхар түгжигч боолттой, torques өөр дээрээ тохируулах чангалах боломэжтой сулардаггүй боолтны шилдэг технологи юм.
Superbolt™ Solution of MJTs, Studs & Flexnuts first installed as active field test in December 2007
НОРД-ЛОК боолтны технологийн төгс шийдэл
Factory bolting configuration for the front strut limits access for the technicians and proper tooling.
• Safety concerns working with high energy tooling in confined space.
• Lack of proper reaction point for conventional tooling meant tooling would often slip adding to the danger.
• The factory specified Torque/Turn to Yield tightening method, does not achieve adequate preload for the severe service conditions.
• Inadequate preload then results in factory bolts failing in yield or fracture.
• Bolt failures often result in damage to the mounting faces necessitating expensive field machining and downtime in order to repair fretting damage.
