Non-Impacting Electric Wrench
Whatever turns your crank ...
Whether
the DTI is installed under the bolt head or on the nut end separated from
the nut by a flat washer, bolt installers can turn the nut with whatever
tool they have, usually air powered impact wrenches.
But now there is an alternative to impacting, and Applied Bolting sells it. It's our Maeda-built reaction-arm non-impacting 900 ft-lb electric wrench. We sell them to erectors who don't want to use air tools, at least not for all their bolts. These erectors put the DTI on the nut end, and don't bother to hold the roll.
This means it's a one-sided one man installation procedure with the advantage to the operator of knowing when the bolt has been sufficiently tensioned, as opposed to when it reaches a certain torque and breaks off, which is what twist-off bolts do.
So
the ease of electric tools from Applied Bolting is now available for regular
hex bolts, just like it is for twist-off bolts. Whad'ya know?
The state-of-the art in 120 volt non-impacting electric bolt tightening wrenches. 240 volt also available. Requires no compressed air: just plug in, engage the reaction arm, and go.
Available in three models of 520, 900, and 1550 ft-lb torque capacity as shown (STC or SR), and to 2600 ft-lb in a different model shape (PG). Model STC11A (900 ft-lb capacity) tightens a 7/8" bolt in 5 seconds from snug without operator fatigue. Variable torque settings limit output when needed.
If used with DTI's, bolts are tensioned with ease and accuracy. Quiet operation with equal power forward and reverse. "Soft start" clutch for operator safety.
