Torque Multiplier
A powerful robust, Versatile portable and Accurate Tool :
Tristar torque Multipliers provides extra mechanical advantage needed to tighten or loosen stubborn nuts and bolts located in cramped or (in accessible) positions. A manual Tool, particularly recommended where no compressed air/electric power available for use of Power Tools.
Tristar torque Multipliers increases the torque capacity of Torque Wrenches , Hand Ratchets/Wheel Braces at the input end by a factor depending on the model selected. This enables the operator to achieve high levels of torque safely and easily.
With continuous R & D efforts, we have two variety of torque multipliers in our product range the conventional
‘AM’ series and a more compact and light weight ‘TVR’ series.
A testimony on the use of Tristar Torque multipliers from our client at Estonia , M/s Metsateknika As.
We tested this tool in January 2003, Hydraulic Hammer was Krupp HM 1500 Marathon V. First Tightening of Bolts (55 mm) was 500 Nm. After that , We had to Tighten Bolts two times 120” Degree (240 Degree). It was really easy to do this job with Tristar Torque Multiplier 9/25. The Tightening arm was only 45 cm long. During final tightening, I mentioned how our mechanic smiled. It was easy to do the job only with one hand he has really good tool. Next day I told about this experience to our good friends in Finland-Jasto Oy . There are selling Atlas Copco and Krupp Hydraulic Hammers in Finland. Now there are also thinking about buying this Torque Multiplier.“ Mr. Harri Ummik.
