Port Danubia Speicherei in Austria relies on a SENNEBOGEN Port Handling Giant

A project with impact – this is what the “big green one” built for Danubia Speicherei Ges.m.b.H in Enns, Austria, truly is.

Together with SENNEBOGEN sales and service partner Ascendum Baumaschinen GmbH, the port specialists successfully completed the major project, the assembly and commissioning of the world’s largest material handler.

Leaving the nearby main road opens up a unique view across the port area in Enns, Austria: with 3.5 million m² and around 2,500 m of quay, the Danube port is one of the most important inland ports in Central Europe. And since the middle of 2020, thanks to the investment by Danubia Speicherei Ges.m.b.H., the scenery gained a new outstanding landmark.

With the SENNEBOGEN 895 E series, state-of-the-art material handling technology has made its way to Danubia Speicherei Ges.m.b.H: “We were looking for the perfect solution for our business, without having to make any compromises. At bauma 2019, the decision was made,” explains Georg Dobesberger, Managing Director of Danubia Speicherei, about the chronological development of the project.

The previous solution with two rope-driven harbour cranes was already out of date at that time, the supply of spare parts was becoming more and more expensive due to their age, and the handling volume at their quay was continuously increasing. Today, a volume of around 950,000 tons of material of all kinds, from grain and fertilizers to salt and general cargo, is being handled on the company’s quay each year.

Customized machine design: Use of the existing track width, development of a safe access concept, loading of trucks and wagons simultaneously
Use of the existing track width led to development of a safe access concept.

What is special, however, is that the quay walls are rather high, depending on the water level – and only the 895 with its enormous dimensions was able to meet all of Danubia Speicherei’s requirements in terms of range, depth and speed.

Together with Ascendum Baumaschinen in Austria the considerations were put into practice: A rail gantry adapted to the gauge width of the existing rails, a reach of 35 m, a port cab that can be elevated and lowered by 7 m, a well thought-out access concept as well as a power supply over 300 m travel distance.

Electric Engine and Recuperation Technology

Georg Dobesberger knows that with the increased demands of the market, it is necessary to rely on modern technologies: “With the electric motor of the port giant, on the one hand, we are using a drive option that is both resource and environmentally friendly. On the other hand, due to the lower electricity prices, this also makes sense from a financial point of view.”

The 895 E series works efficiently in two ways: Maximum energy savings can be achieved by combining an electric motor with the latest recuperation technology. SENNEBOGEN’s Green Hybrid system is unique on the market because it operates with virtually no reduction in performance along the entire cylinder path: Due to the large system volume of the two hydraulic cylinders on the boom in combination with the nitrogen and piston accumulators next to the boom pivot point, the force remains constant and compensates for the mass of the 54 t boom. Like a spring, energy is stored by lowering the boom and compressing gas.

The system then uses this energy to support the next lifting task, which is similar to releasing the spring. This minimizes the amount of force required for lifting and reduces energy consumption by up to 55%.

Power Supply on the Gantry Rail

Big machines can cope with even bigger tasks, which is true for the 895 E series, as the machine is specialized in many different areas while remaining extremely scalable. Be it general cargo or various bulk materials, everything can be handled at Danubia Speicherei at ease: Therefore, the port specialists integrated a quick-change system on the stick with various grab applications in order to flexibly switch between handling heavy and light bulk materials as well as general cargo.

“The greatest flexibility, however, results from the fact that we can unload ships along the entire quay,” Georg Dobesberger continues. For this purpose, a special power supply was installed on the rail gantry via a motorized cable reel, which allows the electric material handler to move easily and conveniently along a total distance of 300 m.
