Torque Multipliers
MADE IN USA
Why use a torque multiplier?
Fast – Our input torque holding ratchet assists in holding our
multiplier in place while applying torque to fastener, making fastening
safer and faster. This feature is standard on all models except
9S290P, 9S291, 9S292 and 9S391.
Wright Tool offers a complete line torque multipliers. These tools offer
a simple, inexpensive solution to common bolting challenges. Our
multipliers ranging in output torque from 750 ft. lbs. to 8,000 ft. lbs.
typically require a maximum input torque of only 200 ft. lbs. or less. All
of our tools can be operated with any standard torque wrench and will
“multiply” the torque to achieve significantly higher torque outputs. We
offer both reaction bar multipliers, which will typically react against a
flange, as well as reaction plate multipliers designed to react against an
adjacent bolt. Other features of these tools include: Easy To Use – Our low input torque requirement makes our tools
easy to use. Most tools require less than 200 ft. lbs. input to obtain
the multipliers maximum output torque.
Safe, Light – Our unique one-piece construction requires use of
just one tool. A single tool is easier to handle and safer to operate
vs. stacking a number of multipliers. Single piece construction also
makes the package smaller and lighter. Precise – An angle of turn protractor included on our 9S391, 9S392
and 9S393 models allows the user to use torque/angle of turn
method to tighten fasteners more accurately.
Service & Support – Excellent application assistance and product
support is always available.
Simple – A torque conversion chart is attached directly on top of
each tool to show the operator the torque input required for a given
torque output.
Accurate – Use of needle roller bearings produces more efficient and
repeatable output torque (all except 9S290P, 9S291 and 9S292). All
models except the 9S292 have a torque accuracy of +/-5%.
Torque Multipliers
Features of the 9S290P, 9S291, 9S391 & 9S292
• • Compact
A torque multiplier is used to reduce the effort needed to tighten or
loosen a fastener. By using a torque multiplier, thousands of foot
pounds of torque can be accurately applied with a standard 250 foot
pound torque wrench.
• • Low cost
• • Light weight
• • Rugged construction
Example: 9S391 Ratio is 13.6 For every 1 ft. lb. input, the
output is 13.6 ft. lbs. If the customer needs 1,400 ft. lbs. of
torque: 1,400/13.6=103 ft. lbs. of input torque. So the torque
wrench needs to be set for 103 ft. lbs. When 103 is achieved
multiplier will be sending out 1,400 ft. lbs. to the socket. There
is a sticker on the handle of the multiplier to give the user the
correct settings in ft. lbs. and Nm (Newton meters). It has the
input and output ranges.
