Product quality plus service strength: Combined solution for crane technology

Stödtlen is a seemingly unremarkable municipality with a population of 1800 in the Ostalbkreis district of Baden-Württemberg. Yet first impressions can be deceptive. It is the base of one of Europe's leading specialist crane suppliers – Gloning Krantechnik GmbH. The sophisticated crane systems from Gloning are used in the production halls of a whole range of industries. Examples include aerospace engineering, mechanical and plant engineering, logistics and renewable energies.

Crane technology plays a key role in customers' production processes. There is more than heavy loads hanging on the crane hook – a large part of the production success does, too. This is why customers are so demanding in terms of quality and performance. The quality of the individual components is key to overall quality – one of the reasons why Gloning uses system components and service from SEW‑EURODRIVE for all its drive technology needs.

Gloning utilizes our wide-ranging portfolio to cover all the drive functions of its systems – from hoists to travel applications, and including frequency inverters and controllers. The export-oriented SME with operations throughout Europe also values our international service portfolio. The programming services of our Electronics Service is a real ace up the sleeve for Gloning.

P series planetary gear units save space and weight

Gloning uses one product category on a particularly frequent basis – compact P series planetary gear units. Distributing the load across multiple planet gears makes it possible to transfer high torques in a comparatively small installation space . Planetary gear units are only about half the weight and volume of helical or helical-bevel gear units. The mass of a helical or helical-bevel gear unit for a crane with a load-bearing capacity of 22 metric tons is around 2.5 metric tons, for example. By contrast, a comparable planetary gear unit weighs just 1.5 metric tons.

This difference has a major impact, particularly in the hoists of cranes that are directly connected to the production hall. Examples in this category include traveling, overhead and bracket cranes. This is the location of the hoist in the trolley that is responsible for transporting loads horizontally. The lighter the gear unit, the lighter the trolley, which, in turn, has an impact on the box girder. The box girder does not need to be as sturdy to carry the trolley as it moves through the hall. The overall mass of the crane system is therefore lower, lessening the strain on the supporting and hall structures.

Equally important is the lower volume, as the compact planetary gear units enable Gloning cranes to use all the space available in the hall. This is particularly important for industries and applications where literally every centimeter of a hall's floor and ceiling counts, such as in the steel trade.

Another special feature: When calculating torque, we can work with a defined service life as well as fatigue strength. . That means the gear units are designed from the outset for a specific total number of operating hours – a standard procedure in crane construction. As a result, the gear units can be run with a torque that is up to 25 percent higher. Gloning is harnessing this benefit and using planetary gear units in smaller sizes. This reduces the weight and procurement costs even further.

Customized software from Bruchsal optimizes applications

As digitalization progresses, crane systems are becoming increasingly intelligent. The importance of software and control programs is therefore growing. Standard applications, such as lifting and traveling, are already included in our inverters' scope of delivery.

In contrast, more advanced applications require customized programming, which is why Gloning is keen to make use of the experts from our Electronics Service. Where necessary, our engineers carry out fine-tuning on site and perform startup.

Our service engineers often optimize the software under real conditions. One typical example is synchronization functions. These enable crane systems to move inclined loads with minimal demands on time. If such a load is attached to a crane, one or more hooks are lower than the others. The automated synchronization function controls each hoist individually and balances out the differences. Normally, operators would have to wait until the load is horizontal. However, thanks to synchronization, they can continue moving while the hooks are still moving automatically to the end height.

What's more, the specially written programs are the property of our customers, representing special added value for Gloning GmbH, which can rely on the technology, service and software from SEW‑EURODRIVE at all times.
