Safety and precision count when moving freight containers. On the one hand, the ton-weighing load must never work loose from crane or spreader during transport. On the other hand, the technology must allow for high precision positioning of the container. Apart from the planetary gearing, other gear systems by AUMA Drives are applied.
Planetary gearing in “Twistlock”
Container spreaders work like hands of the pick & place unit and must precisely lock into the standardised loops of the freight container. In the twistlock mechanism, a planetary gearing ensures that the container is safely lodged in the transport loops and remains fixed.
Transmission ratios i=4 and i=5 available
Delivery including hydraulic motor possible
Compact overriding gear for coaxial speed reduction
Helical worm gear units
Apart from that, Helical worm gear units by AUMA Drives are deployed in the drive system and the telescopic function of the flipper arms, assisting the crane operator in alignment and centring of the spreader.
2 sizes available with 0.55 and 0.9 kW nominal power
Self-locking design with integral overload slip clutch
Enclosure protection IP66 for reliable use in wind and weather
The benefits of planetary gearings become evident with the sub-assemblies of AUMA Drives during daily mission. Their compact design ensures that they can be deployed even in environments with small installation space: High torques are distributed on several gear wheels and allow for fast load change without interrupting the power train. Thanks to these characteristics, they are perfectly suited for permanent use in logistics applications or conveyor technology. These highly demanding applications require utmost precision during gear unit production which has a long-standing tradition at AUMA Drives.
