Hydraulic rotators for cranes and gripper arms


Hydraulic rotators for excavators and construction machinery


Hydraulic rotators for special applications

Archimedes Gerotor Principle

Our superior drive technology with gerotor principle is based on a strong forged drive shaft made of special steel and withstands the highest bending moments.

Uniform & Compatible Hole Circles

Every hydraulic rotator available on the market can be replaced with an AVS rotator with identical mounting dimensions. We are happy to help you find the right type!

Robust & Compact Design

Our low-wear control system allows a long service life at compact dimensions and common connection dimensions.

Powerful Start-up & Smooth Braking

AVS rotators offer a powerful, slow and smooth start-up and, thanks to the construction-related positioning brake, also a smooth braking behavior.

High Bending Moments & Loads

Our rotators offer high bending moments and, thanks to tapered roller bearings and double-bearing drive shafts, also enormous radial and axial load capacities.

High Quality Sealing System

Exterm resistant, twisted and hydrolysis resistant special seals ensure smooth operation over a wide temperature range.


Innovative design & outstanding technology

made in AUSTRIA

For over 25 years, we have been developing and manufacturing high-quality hydraulic motors based on the Archimedes G-Rotor principle.

The compact design, uniform and compatible bolted holes, smooth braking behavior, high bending moment and a high quality sealing system characterize the robust motors.

Customers in and outside Europe appreciate our quality made in Austria.
