About This

• 100-800 Ft-Lb Heavy-Duty Torque Range: This 3/4 torque wrench delivers a true 100–800 ft-lb working range for construction equipment, agricultural machinery, and heavy-duty fleet applications that exceed standard torque limits. Ideal for loader arms, excavator joints, crane outriggers, grader and bulldozer frames, large trailer suspension systems, and high-torque wheel assemblies beyond 650 ft-lb.
• 40cr Chromium Steel Strength: Constructed from heat-treated 40Cr chromium alloy steel, this heavy duty torque wrench offers superior tensile strength and fatigue resistance under repeated high-torque cycles. Designed to maintain stable torque output in demanding jobsite and equipment maintenance environments.
• Dual-Direction 45-Tooth Ratchet: Heavy-duty 45-tooth ratchet mechanism prioritizes structural strength and load-bearing stability under extreme torque conditions. Engineered as a dual-direction torque wrench, the bidirectional ratchet head supports both clockwise and counter-clockwise directions. Featuring a quick-release button, it allows for rapid socket changes, significantly boosting efficiency in heavy equipment workshops
• 48" Extra-Long Handle For Maximum Leverage: Extra-long 122 cm handle provides the leverage required to reach up to 1000 ft-lb with improved control and reduced physical strain. Ergonomic TPR + ABS grip delivers secure handling in oily, dusty, and harsh industrial environments.
• Professional Calibration & Storage System: Each 1 inch drive torque wrench is factory-calibrated to ±3% accuracy and meets ISO 6789, GB/T 15729, and ASME B107 standards. Supplied with calibration certificate and heavy-duty protective case—trusted for critical high-torque industrial and structural assemblies.
