The variants of our bridge crane package solution are specifically geared to your requirements and support machine and plant manufacturers with optimized solutions for many applications.
Distinguishing features of bridge cranes
The variants of our bridge crane package solution can be flexibly adapted to your specific requirements. Bridge cranes differ mainly in the required span width, the working load, dynamics, and positioning accuracy. Our bridge crane package solution therefore has different variants in order to accommodate these requirements.
Choose your optimal drive and control concept from our wide range of variants, regardless of whether you need these for large, small, manual or automated bridge, overhead or wall traveling cranes. The predefined variants make it simpler for you to select the right components for your optimal solution.

Predefined variants for the perfectly tailored solution
Bridge crane with pole-changing motors
Bridge crane for simple transport applications
The bridge crane package variant with pole-changing motors is designed for low requirements on dynamic properties and positioning accuracy. Use this variant to complete simple transport processes. Do you transport light loads for which swinging is not a crucial issue for you? If so, this variant is ideal for your application!
We have intentionally not included expensive control and feedback systems. Our gearmotors used here can be operated directly from the power supply. They switch between the pole pairs when starting up and the speed is changed gradually as a result.
Bridge crane with frequency-controlled motors
Reduced movement by using defined acceleration
Our bridge crane package with frequency-controlled motors is designed for medium requirements on dynamic properties. Use this variant to complete transport processes with heavy loads. Adjusted acceleration and deceleration ramps substantially reduce the movement of transported goods.
Bridge crane with speed-controlled motors
No movement of heavy transported goods
We have designed our bridge crane package with speed-controlled motors to prevent movement of heavy transported goods. This allows you to position the load accurately even when transporting heavy objects. This controls the frequency inverters using adjusted acceleration and deceleration ramps in a closed loop system with encoder feedback.
Bridge crane with regulated trolley
Synchronization increased process reliability
We have designed this bridge crane variant with regulated directional stability in order to guarantee directional stability. This allows you to prevent the distortion or blocking of crane bridges at different crane trolley speeds. This is achieved through control electronics in the bridge crane which undertakes the synchronization of the two trolley sides to ensure regulated directional stability (SyncCrane).
Distinguishing features of bridge cranes
The task of all bridge cranes is to transport loads in a hall. There are differences, however, in the requirements for positioning accuracy and speed. We have taken these differences into account in the bridge crane package in the form of different variants. The predefined variants make it easier for you to select the right components for an optimum solution.
