When load exceeds
the rating determined by precision tempered torque springs, the unit's
drive key pivots out of a slot to disengage the coupling. Once the overload
is removed and speed reduced, the Torq-Tender resets itself automatically.
H-TLC:
The Torque Setting Is Adjustable. If operating conditions require
periodic changes in torque settings, the H-TLC gives you that ability.
Simply adjust the unit's external compression bolts until the desired
new setting is reached.
It works on a spring-
loaded convex pin and detent design which reacts to overloads...but
not to lubricants. Unlike friction-type designs, you can submerge an
H-TLC in oil and still depend on precise disengagement at your design
limits.
