TWHC Square Drive Hydraulic Torque Wrench –

Features and Benefits

Quality means Lower Cost of Ownership:

  • Designed for high cycle life: 2 to 3x more than existing technology
  • Increased reliability: simple drive assembly means less downtime
  • Corrosion-resistant material used for use in harsh environments

Enhanced Usability:

  • Compact nose radius allows the tool to fit in tighter, hard-to-reach spaces
  • Low weight, high strength design
  • Fast operation, long-stroke, and optimum flow
  • Multi-direction high flow swivel manifold
  • Push-button square drive reversal and reaction arm positioning
  • Push-button release of square drive & reaction arm for all models except TWHC50.

Square Drive Hydraulic Torque Wrench is Designed with Safety in Mind:

  • Fully enclosed drive mechanism for operator safety
  • Swivel manifold internal relief valve prevents retract side over-pressurization
  • Fine tooth pawl prevents tool “lock-on”

Handles Sold Separately

The tool’s designed long-stroke mechanism imparts a minimum 30-degree nut rotation per stroke while maintaining a tight and compact nose radius. This is a clear advantage over the short stroke and back-up pawl mechanisms of light alloy competitive models.

Fewer parts and reduced torsion in operation – equals reduced wear, maintenance, and associated costs.
