Heavy-Duty Torque Multipliers for Extreme High-Torque Bolting Applications
Browse ConnexTool's 20-piece range of planetary-gear torque multipliers from Stahlwille (MULTIPOWER), Bahco, and Gedore (DREMOPLUS ALU), engineered to convert modest hand-applied input torque into massive output force. Purpose-built for wind turbine tower assembly, flange bolting, structural steel erection, pressure vessel maintenance, and heavy plant overhaul, these gearboxes deliver output torque up to 9,500 Nm from input forces a single technician can safely generate by hand.
Planetary Gear Reduction, Reaction Arm Engineering & ±4% Precision Multiplication
Torque multipliers in this category use an internal planetary gear train to amplify input torque by a fixed ratio, allowing an operator to generate several thousand newton-metres of output using a standard input torque wrench and hand force alone. Stahlwille's MULTIPOWER MP series and Bahco's numbered gearbox line achieve accuracy within ±4%, with output capacities ranging from 800 Nm on compact single-stage units up to 9,500 Nm on the heaviest Bahco 9625 model. A reaction arm or plate transfers the counter-torque generated during multiplication into an adjacent structure or fixed point, and configurations vary by application: straight arms for open access, offset arms for clearance around obstructions, flat-plate designs with a sliding contact point for adaptable bracing, and ratchet-lock or quick-change mechanisms that let technicians reposition the tool without fully disengaging the drive. Input and output square drives typically span 1/2" to 1-1/2" depending on capacity class.
A Comprehensive Blueprint of Torque Multiplier Configurations
Our catalog spans reaction-arm styles and output capacities to match every heavy bolting application:
- ✔ Compact Single-Stage Multipliers: Stahlwille MULTIPOWER MP300 series with straight reaction arms, delivering 800 Nm to 3,000 Nm output from 1/2" or 3/4" input drives for portable, field-ready use.
- ✔ Extreme-Capacity Heavy-Duty Multipliers: Bahco's 9625-9500 and 96255CR-7000 models and Stahlwille's MP100-1500, reaching up to 9,500 Nm output for structural, marine, and wind-energy bolting projects.
- ✔ Quick-Change & Offset Reaction-Arm Systems: Bahco 89049TM, 9505-TM, and 8905-TM models featuring interchangeable straight and offset arms for rapid reconfiguration around clearance constraints.
- ✔ Ratchet-Lock & Sliding Flat-Plate Reaction Systems: Bahco's 9526B/9527CR/89222CR ratchet-lock range and 9525-3400 flat-plate sliding-point design, plus Gedore's DREMOPLUS ALU offset and straight-arm multipliers, for adaptable bracing on irregular structures.
