Manual type, suitable for the occasions where it requires for high torque while power supply or space is limited.

Torque  increasing system of precise planetary gears, compact structure. 

Strong and durable, easy maintenance, accuracy: ±5%.


1. The torque multiplier uses an efficient planetary transmission mechanism as the main transmission, which is small in size and light in weight. Due to the large transmission ratio, a small input force can produce a large output torque, and the oblique reaction leg can be freely changed at 360°.

2. The operator only needs to apply a small force to obtain 4-28 times of output torque.

3. The matching Torque Wrench can preset the torque according to the transmission ratio, reach the corresponding pre-tightening torque, and automatically send out a signal "click" alarm, accompanied by obvious hand vibration, so as to easily complete the fastening and disassembly of bolts and nuts.    111Manual type, suitable for the occasions where it requires for high torque while power supply or space is limited.

Strong and durable, easy maintenance, accuracy: ±5%.

All models are equipped with anti-returning device, to improve operation convenience and security.

High torque/weight ratio, assisted with Manual Torque Wrench, to easily realize precise assembly of bolts/nuts.

Easily switch from clockwise to anti-clockwise direction by the reversing bar and buttons.


Hand Torque Multiplier with Split Reaction Arm uses an efficient planetary transmission mechanism as the main transmission, which is small in size and light in weight. Due to the large transmission ratio, a small force input can produce a large output torque. The flat reaction arm can adjust the position of the stressed cylinder according to the working conditions.

The operator only needs to apply a small force to obtain 4-76 times of output torque.

The matching torque wrench can preset the torque according to the transmission ratio, reach the corresponding pre-tightening torque, and automatically send out a signal "click" alarm, accompanied by obvious hand vibration, so as to easily complete the fastening and disassembly of bolts and nuts.

What is a Hand Torque Multiplier?

Answer: A Hand Torque Multiplier is a tool that is used to apply high torque values to bolts or nuts without requiring excessive physical effort. It works by using gears to amplify the force applied by the user.


How does a Hand Torque Multiplier work?

Answer: A Hand Torque Multiplier works by using a set of gears to convert the user's applied torque into a higher output torque. The gear ratio in the multiplier determines the level of force amplification.


What are the advantages of using a Hand Torque Multiplier?

Answer: Hand Torque Multipliers offer several benefits, including the ability to apply high torque values without requiring exceptional physical strength, improved accuracy, ease of use, and versatility.


What are the common applications for Hand Torque Multipliers?

Answer: Hand Torque Multipliers are used in various industries, including oil and gas, power generation, heavy equipment manufacturing, aerospace, and automotive. They are used to tighten large bolts, flange connections, and other critical fasteners.


How do I choose the right Hand Torque Multiplier?

Answer: When selecting a Hand Torque Multiplier, factors to consider include the required torque output, the application, the size and type of the fastener, and the user's physical capability. Always consult the manufacturer's guidelines and specifications to ensure proper selection and use.
