Controlled high-torque amplification with Gedore DVV-40Z

Practical benefits

Effortless high torque output: The two-stage planetary gear with a 1:16 ratio lets you achieve tightening torques up to 4000 Nm with minimal input effort.
Rugged lightweight aluminum housing: High-performance aluminum construction provides extreme durability while keeping overall tool weight low for easier handling on demanding jobsites.
Stable reaction force absorption: The included cranked Z-shaped reaction arm securely counters torque forces during controlled tightening and loosening of heavy-duty bolt connections.

In a nutshell

The right choise for

With the Gedore DVV-40Z torque multiplier dremoplus ALU, you achieve controlled tightening and loosening of heavy-duty bolted connections up to 4000 Nm. The two-stage planetary gear system with a 1:16 gear ratio delivers high torque output with minimal physical effort, eliminating the need for hazardous breaker bars. Its high-performance aluminum housing combines rugged durability with reduced weight for comfortable handling in plant engineering, bridge construction, and heavy equipment maintenance. Equipped with a 1/2" female square input and a 1" male square output, it includes a cranked Z-shaped reaction arm to safely absorb high counter-torques. It comes complete with a sturdy transport case and a factory test certificate with a setting table.
