New battery powered torque wrench ITH ADS with class-leading weight-to-power ratio
22.03.2016
The smallest and lightest battery-powered nut runner (battery powered torque wrench) with torque capabilities up to 4,000 Nm (2,950 ft*lbs) was developed by ITH Bolting Technology. Read our press release and download the PDF-file.
The new battery driven torque wrench model ADS has the best power-to-weight ratio (Nm/kg) of its class coupled with an industry-leading high battery capacity of 5.2 Ah. The ITH type ADS also features a brushless motor (wear-free) with automatic shut-off when the target torque value is reached. A high precision of ± 4% is possible due to the intelligent torque control system which automatically adjusts the rotations per minute (rpm) throughout the bolting process.
The high-capacity 5.2 Ah battery makes the ITH type ADS the ideal torque tool for all bolted connections bigger than M16 (3/8”).
High-capacity battery 5.2 Ah is essential to lasting performance
Battery-driven nut runners are ideal for use on sites where power supplies are not – or not easily – available. When considering battery performance people often overlook the importance of capacity in Amperehours and only focus on voltage (V).
Capacity is integral to untiring performance. “The higher the capacity, the more power can be stored”, Dipl.-Ing. Frank Hohmann explains, who leads the worldwide acting family-run company ITH Bolting Technology together with his brother Dipl.-Ing. Jörg Hohmann. Based on this, the decision was made to use a 5.2 Ah 18V battery when developing the new torque tool.
Consistent development: small, light, and powerful
Next to endurance the key factors for battery torque tools tools are size and weight to guarantee the best handling possible – especially on applications where space is limited.
“Getting the best out of these key factors was our target during the development process. We followed this approach consistently and are confident with the result”, Frank Hohmann says.
The first battery-version of the ITH Nut Runners series was successfully introduced five years ago. This new 3rd generation introduces a newly designed high-performance planetary gear drive which had a significant role in achieving the class-leading power-to-weight ratio (Nm/kg).
Features of the nut runner type ADS: ergonomic and user-friendly design
In addition to the automatic shut-down feature which occurs when the target torque value is reached, the ITH type ADS has another feature known as Automatic Free-Run which eliminates the torsional binding that can make it difficult to remove a torque tool after tightening each bolt. The ADS-3 automatically frees itself for the user making it safer, faster, and easier to move from bolt to bolt.
The positioning ring allows the gearbox unit to be rotated in 360° and independently of the drive and then locked into position which makes setup at each bolt quick and easy. During the bolting process the tool endures all of the reaction forces, protecting the user from any strain.
Smart nut runner electronics: precision and feedback for the user
A high precision of ± 4% is achieved by the redeveloped „ITH Soft-Turn-Automatic“ which continuously readjusts the rpm of the brushless electronic motor according to the bolting procedure. The user receives feedback about the bolting process from the motor LED, which is placed on the back of the housing:
- Procedure in-process (LED flashes slowly),
- Target torque reached (LED lights up permanently),
- Error or battery low (LED flashes quickly).
Using ADS Professional or Basic, two extra LED-lights on the foot of the non-slip pistol grip shed light on the bolted application for a clear working environment.
Universal use
Battery nut runner ITH type ADS can be used for service-jobs on all bolt connections bigger than M16 (3/8’’) like for example:
- Wind turbines (especially offshore)
- On construction sites: cranes, construction machines of all types, HV-standard bolt connections of common steel constructions (I-beams)
- Common machine engineering bolt connections

An untiring performance for service jobs is guaranted by the high battery capacity of 5,2 Ampere-hours (Ah). In the picture you can see bolts of a ship container loader („straddle carrier”) are tightened quickly and precisely with an ITH ADS-150.
These M20 (3/4``) motor carrier bolts are tightened with an ITH battery nut runner type ADS-150.
In this picture the ADS-150 is shown tightening one HV-standard bolt connection size M27 (1 1/8’’) on an I-beam of the new headquarter of ITH Bolting Technology in Germany.
