The table lists all available EB-S and PC-S models of the alkitronic N-Tools torque multipliers for mining trucks. Each row shows the key specifications to compare models side by side.

How to read the table of 10 variants

• Model: Identifies the specific variant. EB-S are battery-driven, while PC-S are pneumatic-driven.
• Torque range (Nm): The working torque capacity of each model. This indicates the minimum and maximum torque the multiplier can deliver.
• Square drive (B): The drive size, either 3/4″ or 1″, which determines the compatibility with sockets.
• ØD1 and ØD2 (mm): Approximate diameters of the gearbox area, useful for checking clearance in wheel applications.
• Order No.: The alkitronic reference number for purchasing or spare parts ordering.

For example:

• The EB-S 150-N12 covers 150–1400 Nm with a 3/4″ drive, suitable for medium wheel bolts.
• The EB-S 350-N18 reaches 480–3500 Nm with a 1″ drive, handling the largest mining truck wheels.
• Pneumatic options like PC-S 125-N12 or PC-S 280-N18 are chosen where compressed air is available or required for explosion-proof environments.

This structure makes it straightforward to select the correct model based on torque demand, drive size, and operating environment.

Application of alkitronic N-Tools
torque multipliers for mining trucks

Manufactured in Germany, alkitronic N-Tools maintain joint quality better than impact wrenches or hydraulic torque wrenches. They are essential in mining operations and in the maintenance of heavy trucks.

• Economic and safe operation without costly weather-related downtime.
• Higher joint quality ensured by continuous rotation of the square drive.
• Comfortable, stress-free working with 360° motor rotation and one-hand CW/CCW control.

Technical notes

The compact aluminum housing is corrosion-resistant and impact-proof, while the ergonomic non-slip grip supports safe handling. Features such as the OLED display and alkitronic® Smart Service provide clear operation and complete bolting documentation.

EB-N battery torque multipliers combine mobility with high efficiency. They use a brushless synchronous motor with processor-controlled automatic shut-off, ensuring repeatable accuracy of ±3%. Two Li-Ion batteries are included for continuous operation in open-pit mining and outdoor environments.

• When loosening bolts, release torque may be up to 20% higher.
• Optimal operating conditions: pressure 2–7 bar, air flow approx. 10–15 l/s. Torque accuracy depends on the stability of the supply system.
• Dimensions and comparison

Both battery-driven and pneumatic-driven models are listed together for ease of comparison. For example, the EB-S N12 model has an overall height of 279 mm, while the pneumatic PC-S N12 is shorter at 210 mm. All dimensions exclude the impact socket.

Values marked with * indicate millimeters, while dark background indicates inches.

ATV square drive extension

The ATV square drive extensions fit directly with the gear drive and square outputs. They are compatible with both EB and PC models and are available as separate accessories, not included with the tool. Customers may purchase them together with the tool or later as needed.
