In recent years, there has been an increase in large wheel detachment accidents, leading to a growing demand for reliable tightening with torque setters. The electric torque setter we offer, the 'ETS-800X & XL', allows for torque settings that ensure secure tightening without the need for verification. The ETS-800XL features a two-stage automatic transmission mechanism that rotates at high speed during low torque. 【Features】 ■ One-touch switching between three preset torque settings ■ Easy-to-read display even during tightening operations ■ Tightens approximately 200 units on a single battery charge (based on internal conditions) ■ Equipped with a protector to guard against scratches and damage ■ One-touch loosening operation up to a maximum of 800 N·m ■ Compatible with shared reaction force receivers PTS-800E and PTS-800EX-L *For more details, please refer to the PDF document or feel free to contact us.

The "Power Torque Setter" is a portable (hand-held) nut runner that converts the torque generated by an air motor into high torque using a planetary gear reduction mechanism to tighten bolts. Torque can be easily set on the control panel, and a microcomputer controls it using signals from the torque sensor, allowing for high-precision tightening within ±5% without being affected by air pressure fluctuations. 【Features】 ■ Low vibration, low noise ■ One-touch switching available for both right-hand and left-hand threads ■ Battery-operated (dry batteries) so no external power source is needed ■ Soft two-stage start button for safe operation ■ Can connect to a dedicated printer or computer to keep records (optional) *For more details, please refer to the PDF materials or feel free to contact us.

The "PTS Instructor" is a product designed to prevent forgetting to tighten by installing a display that indicates the tightening order and completed locations of hub bolts and nuts on the center hub of large vehicle wheels using LEDs. The tightening results are wirelessly transmitted from the nut runner to the display, allowing for a visual check of the tightening status. After installing the display, you can start the work simply by selecting the number of holes, which enhances the reliability and efficiency of the nut tightening process. 【Features】 ■ The display can be easily attached with magnets or hooks ■ Equipped with a preset function for four types of torque ■ Tightening torque can be managed with an accuracy of ±5% ■ Supports three processes: preliminary tightening, final tightening, and re-tightening ■ Low vibration and low noise allow for loosening work at a maximum of 800N·m *For more details, please refer to the PDF document or feel free to contact us.

The detachment of wheels not only causes roadside breakdowns and hinders other traffic, but can also lead to serious accidents that may involve human lives, thereby undermining social trust. This document provides information on proper handling to prevent wheel detachment, including precautions during daily inspections and maintenance, as well as during wheel installation. [Contents] ■ Precautions during daily inspections and maintenance ■ Precautions during regular inspections and maintenance ■ Precautions during wheel installation ■ Precautions during maintenance that involves removing wheels, such as tire changes ■ Misalignment of aluminum wheels and steel wheels ■ Other precautions *For more details, please refer to the PDF document or feel free to contact us.

The "PTS-800EX-L" is a portable nut runner that achieves high-precision torque control simply by connecting an air hose, thanks to the combination of an air motor and electronic control. It features low vibration and low noise, and is equipped with an automatic two-speed transmission function. It operates without the need for an external power supply, using four AA batteries. Additionally, it can memorize three types of preset torque values, allowing for one-touch changes to the set torque. It automatically stops when the set torque is reached. 【Features】 ■ Low vibration and low noise ■ High-precision tightening torque management enabled by built-in electronic control ■ Automatic stop upon reaching the set torque ■ Equipped with automatic two-speed transmission function ■ Can memorize three types of preset torque values and change the set torque with one touch *For more details, please refer to the PDF document or feel free to contact us.

The Air Nut Runner "PTS Series" is a portable electronic controlled nut runner that achieves torque control simply by connecting an air hose. It features electronic control with a torque sensor that is unaffected by air pressure fluctuations, enabling high-precision tightening torque. It operates at high speed until seating and automatically shifts to low speed for final tightening. Torque can be changed with a single touch, and it will automatically stop at the set torque. It can be used for various assembly tasks in automotive, shipbuilding, construction machinery, construction, bridges, plants, and more. 【Features】 - Torque control can be achieved just by connecting an air hose, eliminating the need for additional equipment! - Built-in electronic control controller provides torque accuracy of ±5% - Easy operation with one-touch torque change - Safety design ensures that it does not operate even if the start lever is pulled during an error occurrence *For more details, please download the PDF or feel free to contact us.

The "ETS-800X-K & XL-K" is a rechargeable nut runner that can centrally manage tightening data for wheel nuts of medium and large vehicles. With each tightening, the product body wirelessly transmits the tightening data, allowing customer and vehicle information to be recorded in an Excel file (CSV) on a computer. The tightening status can be monitored in real-time on the computer screen. Additionally, we will be exhibiting and demonstrating at the "38th Auto Service Show 2025." 【Features】 ■ Available in two types: a short type (800X) without an automatic transmission mechanism and a long type (800XL) with an automatic transmission mechanism. ■ Tightening torque is displayed brightly and prominently with an LED, and the set torque is always displayed on an LCD screen (with backlight). ■ Three set torques can be switched with one touch. ■ One-touch operation allows for loosening work up to a maximum of 800N·m. ■ Equipped with a protector to guard against scratches and damage. *For more details, please download the PDF or feel free to contact us.
