MECHANICAL WRENCHES
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.
