Model SD hydraulic torque wrenches use
standard square drive power sockets* to help you torque industrial size
bolts on heavy equipment. The offset drive-head is designed with the
smallest possible head radius for use on close clearance jobs such as
API and ANSI flanges. Torque reaction is accomplished by placing the
built-in steel reaction arm against any adjacent rigid structure.
Custom reaction arms are available to accomodate most applications.
You'll save time and money using these versatile and compact tools to
torque any nut or bolt from 3/4" to 6" in diameter. We manufacture a
variety of hydraulic torque wrench systems, ranging from those capable
of supplying up to 200,000 Ft-Lbs of torque, all the way down to
systems supplying 200 ft-lbs of torque.
Operation is simple! One worker can
position the wrench on a bolt head and operate the control valve on the
torque wrench. The hydraulic cylinder rod strokes out and turns the
fastener 15° each cycle.
Separate electrical control pendants are not used. When the
control valve is released, the load is removed thus allowing the wrench
mechanism to ratchet in preparation for the next stroke. The open
center valving in the wrench precludes ever "hydraulically locking" the
the wrench onto a nut or bolt. To loosen bolts, the tool is simply
turned over. From the Model SD-1.5 on up to the Model SD-200, you get BMF quality and engineering
built-in. Torque output is accurate within ±3%.
Torque Wrenches are stronger.
Our unique and simple ratchet design engages all 24 ratchet teeth at
one time. Therefore, the torque load is distributed over all the
ratchet teeth instead of high loading on 1 or 2 teeth as in other
ratchet wrenches. There are no pins, no pawls, and no levers in our
ratchet to break or wear out. In fact, we warrant our ratchet mechanism
for a full 3 years.
Torque Wrenches are safer.
Only the worker who positions the wrench on the bolt controls its
operation . Nuts and bolts are made up quicker and more safely because
the time and the risk of coordinating the efforts of a 2-man operation
is eliminated. Most of our wrench Models require only 3000 PSI to
produce maximum torque, compared with the 10,000 PSI required by other
maker's designs. Lower pressure means lower hazard for your workers.
BMF Torque Wrenches are more
Our wrenches are designed with simplicity in mind, incorporating as few
moving parts as possible to limit points of maintenance. We manufacture
our wrenches from either heat treated chrome-moly alloy steel, or high
strength 7075-T6 aluminum, imparting quality and longevity of service
into every wrench we sell. Our low pressure hydraulic systems are
inherently more reliable than high pressure systems.
All of these features combine to give you a
hydraulic powered torque wrench system that can safely, reliably, and
easily torque industrial size bolts.
Model SD Torque Wrenches are available with
Hex Drives to fit directly into Hex Socket Cap Screws. Other options
include remote control valves, and models for subsea service. Ask us if
you have a specific requirement, we can most likely meet it.
stocks large power sockets for virtually any size inch or metric, 6 or
12-point bolt heads. If we don't have it, we can make it for you.
