Wheel Torque Multiplier Rockforce RF-34114102 1:78 Ratio, 6800 Nm Output

The Rockforce Wheel Torque Multiplier RF-34114102 is a heavy-duty mechanical torque multiplier with a 1:78 gear ratio and a maximum output of 6800 Nm. Designed for situations where conventional hand tools or torque wrenches cannot provide the required torque, this compact, portable unit enables controlled application of very high torque for loosening stubborn wheel nuts and for precise tightening in automotive and commercial vehicle maintenance. The construction is engineered for workshop use, tyre service bays and mobile service vans, offering a reliable way to increase torque without power tools.

Advantages

This torque multiplier converts low input torque into a high, stable output torque through a robust gearbox and planetary gearing system, reducing operator effort and improving safety when dealing with heavily fastened wheel nuts. Its compact design and mechanical operation mean no external power source is required, allowing use in confined spaces and remote locations. Built for repeated workshop use, the unit provides repeatable performance and helps protect torque wrenches and impact tools from overload.

Suitable for

• Loosening and tightening wheel nuts on cars, vans and heavy commercial vehicles
• Tyre fitting and tyre service operations
• Workshop maintenance tasks requiring high torque where powered tools are impractical
• Mobile breakdown and roadside service applications

Key specifications

• Gear ratio: 1:78
• Maximum output torque: 6800 Nm
• Intended use: mechanical torque multiplication for wheel fasteners
• Operation: manual, no external power required
• Design: compact and portable for workshop and field use

How to use

Attach the torque multiplier to the wheel nut or fastener using the appropriate adapter or socket that matches the nut size. Apply input torque using a calibrated torque wrench or breaker bar to the input square; the multiplier will deliver the increased output torque to the fastener. Work slowly and steadily, monitoring applied input torque so that the resulting output does not exceed the fastener’s rated torque. After use, release the input torque and remove the multiplier, then inspect sockets and adapters for wear before storage.

Usage recommendations

Use appropriate sized sockets and adapters to avoid rounding fasteners. For tightening, if final torque specification is critical, use the torque multiplier to snug the fastener and verify final torque with a calibrated torque wrench. Regularly inspect the tool for wear and keep it clean and lubricated according to workshop best practices to maintain accuracy and service life.
