Watching the energy level

No contradition between high-speed equipment and sustainability
Is there a contradiction between the high-speed equipment by TGW and the solutions focusing on sustainability as defined by "Green Logistics"? No, there isn’t. Let us tell you why. We make materials handling systems for our successful customers. And we want our customers to be successful with our solution. This is why we are constantly striving for ways to optimize energy use, to implement energy efficient devices, and provide energy efficient processes. But how does energy efficiency and high-performance materials handling solutions go hand in hand? Starting at the basics, already in the development of a product, TGW is searching for the ideal materials to provide a sustainable product. Lightweight construction reduces the moving masses, which also means a reduction of drive dimensions. This results in lower energy consumption and reduced costs for drives and energy, making the products more intelligent.
Optimum energy management is the answer,”
says Christoph Wolkerstorfer, Managing Director at TGW Mechanics. “All dynamic axes are equipped with energy recovery units which save up to 30% of energy. In addition to this, we implement a so called power management system to cut the energy peaks of a system. Furthermore, we implement a lot of other energy saving modes already on PLC level, which enable us to reduce the energy consumption to an absolute minimum.”

The system as a whole

Finding the right system solution is a multi-dimensional task with many influencing factors, but the key is to get the most efficient system. Our Solutions Design department keeps analyzing the most efficient processes of a logistics solution. The calculation of energy consumption permits to determine the future use of energy including costs. This measure allows us to react immediately and to use energy-saving strategies right from the start. “Furthermore, our Warehouse Management System (WMS) strategies permit the balance of the system’s performance,” Wolkerstorfer adds.

Permanently optimizing the system

Even during ramp-up, TGW perpetually optimizes their systems. There are several options such as automatic speed reduction of the storage and retrieval machines and the conveyors as soon as the performance decreases. Automatic shutdown systems of temporarily unused areas of the installation are another possibility of saving, especially in the conveyor systems. The system knows what is going on and just takes the required steps. After the installation is finished, TGW won’t let their customers alone with the high-tech installation. The TGW Lifetime Services provide preventive maintenance to preserve the energy efficient components. Christoph Wolkerstorfer knows: “Additional optimization workshops help our customers to become familiar with their installation and show them how ‘green logistics’ can be implemented in their system’s operation.”

Even beyond the life cycle

As soon as an installation reaches a certain age, there might be the need of a modernization or retrofit. Replacements of IT and controls as well as software are important for the entire system, above all energy management. New WMS strategies and the integration of energy regeneration modules into old systems bring the installation up to date and prepare it for a green future with TGW. You can make a materials handling solution energy efficient, even though it provides you with high performance and fulfills your requirements. An intelligent system is what counts.
