Deep Throat TM design allows the make-up operation of both
joints to be performed with out the necessity of rotating the
power tong 180 0, which results in a reduction of crew
fatigue, establishes a safer environment and saves substantial
rig time. (US Patent 5,482,390)
Zero Side Load TM Integral Back-up completely eliminates all
bending and shear forces induced by conventional power
tongs during make-up. (US Patent 5,099,725)
When configured with conventional inserts, the Frank’s Dual
String Tong is designed with a three-jaw gripping system.
This greatly increases the contact area resulting in a reduction
of die penetration and reduces pipe crushing.
