Torque Multiplier with Planetary-gear Mechanism with Max Output - J.H. Williams

The J.H. Williams JHWTM-393 Torque Multiplier is engineered for professional technicians who require substantial, controlled torque output without relying on impact tools or cumbersome breaker bars. Its robust planetary-gear mechanism delivers up to 3200 ft-lb of precise torque from a 1/2" drive input, making it an essential tool for safely managing high-specification fasteners across heavy trucks, industrial machinery, and complex assemblies.

Key Features

• High Output Torque: Generate up to 3200 ft-lb (4338 Nm) with an 18.5:1 torque ratio, enabling efficient loosening and tightening of stubborn wheel nuts, industrial flanges, and structural fasteners.
• Precision Planetary-Gear Mechanism: This advanced planetary gear torque multiplier utilizes a durable planetary gear set for smooth, reliable power transfer and an extended service life in demanding environments. It multiplies the operator's input from standard torque wrenches.
• Controlled Accuracy: Designed for use with a calibrated torque wrench, facilitating precise tightening on critical joints where repeatable accuracy and documentation are paramount.
• Professional-Grade Durability: Constructed to withstand daily rigorous use in fleet service, heavy-duty truck repair, and industrial maintenance environments, ensuring balanced load distribution and long-term performance.
• Compact Design: With an overall length of 19-39/64", this tool offers a practical alternative to long breaker bars, improving access in confined spaces around wheels, frames, and suspension components.
• Versatile Drive Sizes: Features a 1/2" square input and a 1" square output, integrating seamlessly with standard torque wrenches and sockets to reduce the need for specialized adapters.

Applications

The JHWTM-393 is commonly utilized for Class 6–8 truck and bus wheel service, heavy equipment lug nuts, engine and drivetrain fasteners, industrial flanges, and structural connections that exceed standard hand-tool torque ranges. It is suitable for fleet maintenance shops, heavy-duty truck and trailer service centers, off-highway and construction equipment repair facilities, and plant maintenance operations.
