HSW Series Square Drive Hydraulic Torque Wrenches
Engineering Overview & Structural Features
The HSW Series Square Drive Hydraulic Torque Wrenches deliver 112 to 72,000 N·m (82 to 53,280 ft·lbs) across 3/4" to 2-1/2" drive sizes. Engineered with an aerospace titanium-aluminum alloy unibody and high-strength alloy steel drive mechanism, providing precision tightening with ±3% accuracy and 360° multi-position reaction flexibility.
HIGH-TECH MONOLITHIC AEROSPACE ALLOY BODY
Monolithic titanium-aluminum alloy housing delivers maximum torsional rigidity and impact resistance while significantly reducing tool weight for operator ease.
3D CAD PRECISION RATIO & ACCURACY (±3%)
Computer-modeled internal ratchet mechanism ensures smooth load distribution and torque repeatability within ±3%, calibrated to ISO 9001 standard.
QUICK-RELEASE SQUARE DRIVE REVERSIBILITY
Push-button quick-release square drive allows instantaneous switching between tightening and loosening without disassembly or additional tools.
360° x 180° DUAL-PLANE SWIVEL COUPLER
Multi-axial swivel coupler prevents hose binding and enables unrestricted hose placement in restricted piping envelopes.
360° FINE-TUNING REACTION ARM
Heavy-duty reaction arm with 360-degree multi-spline fine positioning securely locks onto structural reaction points at any operating angle.
OEM Cross-Reference & Dimensional Interchangeability
The HSW Series 700 Bar square drive hydraulic torque wrenches deliver 112 to 72,000 N·m (82 to 53,280 ft-lbs) across 3/4" to 2-1/2" drives with ±3% precision, titanium-aluminum alloy unibody, and 360° swivel coupler. 112 - 72000 Nm Square Drive.
