Torque Multiplier NMK

The torque multiplier is designed for assembling and disassembling bolted joints of large diameters. In particular, it facilitates the releasing of corroded bolted joints. Currently, our company produces two sizes of the Torque Multiplier NMK.

Characteristics

• Exerts big torque by small manual power.
• Designed for tightening bolted joints by specified tightening torque.
• Facilitates the releasing of corroded bolted joints.
• Delivered with socket heads of s = 46 ÷ 155 mm.
• Simple operation and easy maintenance.

Operating Principle and Main Advantages

The torque multiplier operates on the principle of a multi-stage planetary gearbox, which multiplies the input manual force into a significantly higher output torque. Thanks to this, bolted connections can be safely tightened and loosened in spatially restricted areas where long levers cannot be used.

• Extreme Performance: Output torque up to 12,500 Nm.
• High Efficiency: Mechanical transmission with minimal losses.
• Work Safety: Controlled tightening without the risk of operator injury.
• Mobility and Independence: Purely mechanical operation without the need for an external power source.

Complete Equipment Ready for Action

We supply each torque multiplier as a comprehensive set. The standard package includes:

1. Planetary gearbox
2. Robust reaction arm
3. Ratchet wrench
4. Set of impact sockets
5. Durable transport case for safe logistics

Practical Applications and Technological Background

NMK torque multipliers are used across heavy industry, construction, and agriculture. They often serve as a sought-after wheel nut wrench for trucks and heavy machinery. If you are still using an older, traditional Tona torque multiplier at your workplace, our NMK series represents a modern, fully-featured, and more powerful alternative for you.

At the Heart of the Device is Our Planetary Gearbox

The core of the NMK multipliers is a multi-stage planetary gearbox of in-house design. We develop and apply this precision engineering component not only in multipliers, but also in our pipe benders and other industrial systems.

We manufacture planetary gearboxes in a variety of versions (e.g., types for NMK 16-400 and NMK 78-1250 sets, or the standalone NMK 5-1250 gear module). We supply them:

• As an integral part of our machinery
• Standalone for your specific industrial applications
• As certified spare parts

Custom-Tailored Atypical Solutions: Based on your technical specifications, we are able to design and manufacture a custom planetary gearbox with a non-standard gear ratio or dimensions.

We Will Help You with Selection

Torque multipliers are simple yet invaluable tools wherever there is a need to eliminate brute physical force and rely on safety, accuracy, and controlled tightening.
