Driven Hydraulic Torque Wrench - Durable Steel and Aviation-Grade Aluminum, Optimized for Confined Spaces

This Driven hydraulic torque wrench is engineered for precise bolt-tightening in demanding industrial environments. The tool body combines high-strength alloy steel with 70-series aviation-grade aluminum alloy: steel components deliver robustness and wear resistance, while the low-profile design of the power head and working head allows operation in narrow and confined spaces.

It delivers output accuracy of ±3% with 100% repeatability, ensuring consistent and precise torque application. The tool body doubles as a reaction arm, and the oil inlet/outlet ports provide 360° x 180° directional adjustability, allowing smooth hydraulic hose routing regardless of the operating angle. Working heads can be changed easily using a steel quick-release pin, and wear-resistant bronze bushings prevent seizing during prolonged use. For added safety, the hydraulic circuit includes an overpressure relief mechanism.

The wrench accommodates nut sizes across flats ranging from 16 mm to 175 mm, corresponding to a torque range of 232 N·m to 44,593 N·m. Common models are available in stock, and custom orders based on technical drawings, as well as OEM/private labeling services, are supported.
