A Sapsons Torque Multiplier is a specialized mechanical tool designed to increase (multiply) the torque applied by a standard torque wrench, allowing tightening or loosening of heavy-duty nuts and bolts with minimal effort.
Description :
A Sapsons Torque Multiplier is a compact, alloy steel, epicyclic (planetary gear) device used in industrial applications where very high torque is required. It is placed between a torque wrench and a socket to amplify the applied force.
Working Principle :
• The tool uses a planetary gear system to multiply input torque.
• Input torque from a wrench is applied to the multiplier.
• A reaction arm rests against a fixed object to prevent rotation.
• The internal gears multiply the torque and deliver a much higher output.
Formula:
Output Torque = Input Torque × Multiplication Ratio
Typical ratios:
• 5:1
• 25:1
• 125:1
Key Features :
• Made from high-strength alloy steel for durability
• Compact and portable design for confined spaces
• Available in multiple torque ranges (approx. 170 to 4845 kgm)
• Multiplication ratios of 5x, 25x, and 125x
• Comes with reaction bar and adaptable brackets
• Smooth and precise operation
Benefits :
• Produces very high torque with low manual effort
• Reduces operator fatigue and manpower requirement
• Ensures uniform tightening and minimizes flange distortion
• Eliminates the need to dismantle nearby equipment in tight spaces
• Improves safety compared to long leverage bars
Advantages :
• One operator can handle heavy-duty bolting
• High precision and controlled torque application
• Compatible with standard torque wrenches
• Suitable for both tightening and loosening operations
• Minimal mechanical loss due to robust gear design
Applications :
Sapsons torque multipliers are widely used in:
• Power plants
• Refineries & petrochemical industries
• Heavy engineering
• Shipbuilding & maintenance
• Automotive and aerospace sectors
A Sapsons Torque Multiplier is a mechanical tool used to produce very high torque with minimal effort for tightening or loosening nuts and bolts.
• It works using an epicyclic (planetary) gear system that multiplies the input torque.
• The tool is placed between a torque wrench and socket, with a reaction arm supporting against a fixed object.
• It provides torque multiplication ratios like 5:1, 25:1, and 125:1, meaning small input force gives large output force.
Key Points :
• Made of strong alloy steel and compact in design
• Capable of generating very high torque
• Reduces manual effort and operator fatigue (up to ~35000 lb.ft.)
• Ensures accurate and uniform tightening
• Widely used in maintenance, production, and heavy industries
In short :
A Sapsons Torque Multiplier is like a force amplifier—you apply a small torque, and it delivers a much larger torque, making tough industrial fastening jobs easier, safer, and more accurate.
