Description
Torque multipliers are used to achieve very high tightening or loosening torques for bolts and nuts with relatively little effort from the operator. They are used wherever a standard torque wrench is insufficient.
Main applications of torque multipliers:
1. Tightening and loosening large bolted joints
o structural bolts,
o axle nuts,
o flanged joints,
o high-torque joints.
2. Energy industry
o wind turbines,
o hydroelectric power plants,
o generators,
o industrial valves,
o power generation facilities.
3. Aviation and aerospace
o tightening helicopter rotors,
o aircraft turbine maintenance,
o aircraft wheel rim assembly,
o hard-to-reach connections in fuselages.
o
4. Mining and heavy machinery
o maintenance of large machinery,
o excavators,
o open-pit mining machinery,
o large-scale connections.
5. Shipbuilding
o propeller shaft bolts,
o ship propeller drives,
o offshore structures.
6. Heavy-duty automotive and rail
o truck wheel nuts,
o axles,
o suspension systems,
o locomotive and railcar components.
7. Maintenance and manufacturing
o machine assembly,
o gearbox servicing,
o production lines,
o controlled bolt tightening according to quality standards.
8. Work in confined spaces
o where a long wrench won’t fit,
o in tight technical compartments,
o with limited access to bolts.
Typical practical tasks
• tightening wind turbine bolts,
• loosening seized nuts,
• installation of large bearings and hubs,
• tightening truck wheels,
• maintenance of industrial gearboxes,
• assembly of steel structures,
• operation of large industrial valves.
