Battery torque multiplier Alkitronic EAW2, made in Germany

alkitronic® EAW2 is a battery-powered, two-speed torque multiplier engineered for high-torque bolting applications ranging from 90 Nm up to 4,000 Nm. Its angled configuration enhances accessibility and ergonomic handling, particularly beneficial when working in restricted spaces or in environments without direct access to power.

Designed for field mobility, the tool remains operational and efficient regardless of external energy sources, providing consistent and repeatable results in both assembly and maintenance scenarios.

Alkitronic EAW2 is widely used across industries requiring accurate and powerful bolt tightening, including steel construction, power generation, wind energy, heavy machinery, and infrastructure maintenance. Thanks to its compact structure, the EAW excels in on-site applications such as flanged connections, pipeline assembly, and jointing operations on vertical or overhead positions where pneumatic or hydraulic systems are impractical or unsafe.

The key technical benefit of the alkitronic® EAW2 lies in its two-speed gear system

the fast gear enables rapid rundown of bolts, while the power gear applies the final torque with high precision. Each gear offers eleven torque values, allowing precise matching with the required tightening specification.

The unit is driven by a brushless synchronous motor that is not only maintenance-free but also highly efficient, contributing to low running costs and extended service life. Unlike traditional torque tools, the EAW requires no lubrication and generates minimal noise during operation — no hearing protection is needed.

Depending on the torque requirement, users can choose among several models ranging from the EAW2/80 (115–860 Nm, 3/4” drive) to the EAW2/400 (500–4100 Nm, 1½” drive). Each variant is equipped with a CE-certified shut-off mechanism that maintains a repeat torque accuracy of ±3% on identical bolt joints.

Idle speeds vary between models and gears, from 24 rpm in fast gear for lighter units to as low as 1 rpm in high-torque versions, giving operators full control over the application process.

Two 18V lithium-ion battery packs with 5.2 Ah capacity ensure high endurance in the field, supporting up to 360 bolting cycles per charge. Each battery features an LED indicator for real-time monitoring.

The intelligent battery management system further enhances safety and performance by protecting each cell from overcharging and deep discharge, ensuring torque output remains reliable even when battery capacity is low.

The mechanical build of the tool reinforces its durability. Its motor housing is constructed from a special polymer composite that is break-proof, resistant to corrosion, and impact-tolerant. This makes the EAW particularly suited to industrial environments with harsh operating conditions. The integrated angle-drive ensures optimal power transfer and smooth rotation, reducing vibration and enhancing control.
