Marktübersicht Betonpumpen und Verteilermaste
Entwicklungen und Tendenzen
Sonnenberg, Richard
Der Bestand an Betonpumpen beläuft sich nach Angabe des Bundesverbands der Deutschen Transportbetonindustrie (BTB) derzeit auf rund 1387 Pumpen (Stand: 2017), bei einer gepumptem Menge Beton von rund 11182 m³ pro Jahr und Betonpumpe. Die steigenden Anforderungen an die Wirtschaftlichkeit der Bauabläufe sowie strenge Richtlinien hinsichtlich Lärmemissionen und Abgaswerten der Dieselmotoren stellen die Hersteller von Betonpumpen vor immer neue Herausforderungen. Die Entwicklung neuer Maschinen nach dem neuesten Stand der Technik und neue Einsatzmöglichkeiten werden von wissenschaftlichen Forschungsarbeiten begleitet. An der Technischen Universität Dresden wurde das Forschungsvorhaben „Zielsicheres Pumpen von Beton“ der Forschungsgemeinschaft Transportbeton erfolgreich abgeschlossen. Ziel des Vorhabens war es, aussagekräftige Messmethoden für die Vorhersage der Pumpbarkeit unterschiedlicher Arten von Frischbeton und eine einfache Anwendung in der Praxis zu finden. Auch die Hersteller von Maschinen für die Betonbranche ergänzen ihre empirisch gewonnenen Kenntnisse mit Forschungsergebnissen aus eigenen Laboren. Eine Sicherheits-Checkliste für Betonpumpen auf der Baustelle, herausgegeben vom BTB-Branchenportal zum Arbeitsschutz, thematisiert die typischen Probleme, mit denen sich die Maschinisten im Arbeitsalltag beim Aufstellen und Betreiben von Betonpumpen konfrontiert sehen. Die maschinentechnische Ausstattung von Pumpen und Verteilermasten wurden wesentlich verbessert. Zu den Innovationen gehören abgasfreie und leise elektrische Hybrid-Antriebe, gewichtsreduzierte Verteilermaste, effiziente Hydraulik-Pumpbatterien sowie eine neuartige Drehverbindung der Verteilermastarme untereinander mit einem Drehmotor. Dank hochentwickelter elektronischer Steuerungen ist die Bedienung der Maschinen einfacher und sicherer.
Review of the market for concrete pumps and placing booms
According to the BTB (Federal Association of Ready-mixed Concrete) there are currently (as at 2017) about 1387 concrete pumps in existence with a quantity of pumped concrete of about 11182 m3 per concrete pump per year. The rising demands on the cost-effectiveness of the construction sequences and the strict guidelines with respect to noise emissions and exhaust gas values from the diesel engines are continuously presenting the manufacturers of concrete pumps with fresh challenges. The development of new state-of-the-art machines and new possible applications is being supported by scientific research work. The Ready-mixed Concrete Research Association’s research project entitled “Dependable concrete pumping” has been successfully completed at Dresden Technical University. The aim of the project was to find informative methods of measurement for predicting the pumpability of different types of fresh concrete and their simple practical application. The manufacturers of machines for the concrete industry are also supplementing their empirical acquired knowledge with research results from their own laboratories. A safety check list for concrete pumps on construction sites published by the BTB industry portal for industrial safety addresses the typical problems that confront the machine operators in everyday work when setting up and operating concrete pumps. The mechanical equipment for pumps and placing booms has been substantially improved. The innovations include electric hybrid drives that are quiet and free from exhaust gases, weight-reduced placing booms, batteries of efficient hydraulic pumps and a new type of slewing ring with rotary motor for moving the placing boom arms in relation to one another. The operation of these machines is simpler and safer thanks to sophisticated electronic controls.
