Unmatched power and true torque control…
with minimal effort and maintenance-free operation.

• High-strength fasteners for critical applications require massive and accurate torque.
  Field maintenance operations demand portability and problem-free operation. The
  solution is an innovation in wrench technology-mechanical wrenches from POWER-
  DYNE.

• Standard bar torque wrenches are limited to the amount of muscle power that can be
  applied. Conventional torque multipliers augment muscle power, but sacrifice accuracy.
  Electrical or pneumatic tools require a power source, which usually restricts their use to
  the limited area where power is available. No other method of tightening fasteners
  combines the accuracy, portability and ease of use found with POWER-DYNE
  mechanical wrenches.

• POWER-DYNE mechanical wrenches give you accurate torque, when and where you
  need it. On maneuvers, at a remote mining site, or atop a superstructure. Our
  mechanical wrenches can generate from 20 to 20,000 ft–lbs of output torque with
  practically effortless torque input. The design concept is unique: Internal gearing
  multiplies the operator’s input from 50:1 up to 2400:1. The result is more easily obtained
  torque than with other multipliers, and extreme accuracy from minimal input.

• A hydraulic readout system is incorporated in POWER-DYNE’S mechanical wrench
  design which responds to changing torque on the fastener. Actual fastener relaxation is
  directly measured to produce more accurate torque readings than those obtained by
  measuring applied torque. Direct readout of the output torque ensures accuracy to ±2%.
  
• Applied pressure is smooth and balanced. The pure torque couple and smooth torque
  produced with POWER-DYNE mechanical wrenches eliminates side loads, mechanical
  springback and the short duration blows characteristic of an impact wrench. The result
  is safe operation and a properly stretched fastener, with reduced bending and torsional
  stresses.

• POWER-DYNE mechanical wrenches are completely portable, and perform in the shop
  or in the field. Since the mechanical advantage of the wrench is derived from its gear
  train, no external power source is needed. For added flexibility in high-volume, fixed site
  installations, electrical or pneumatic attachments can be accommodated. This innovative
  design provides the ultimate in portable power when required. Seven mechanical wrench
  models are available, including the innovative SIDEWINDER. Each one offers unique
  features and a job-rated capacity to meet most military, construction, industrial or other
  commercial applications where accurate, portable bolt-tightening is a necessity, and
  safety is a must.
