CONCRETE TECHNOLOGY Kniele GmbH, 88422 Bad Buchau, Germany Runkel Fertigteilbau equips its plant for even more demanding tasks ˾ Mark Küppers, CPI worldwide, Germany The Runkel group of companies has its roots in Remscheid, where a construction company was founded in 1898. The opening of a branch in Siegen followed in the 1934. It continued as an independent company in 1954. The enormous housing shortage after the war was also decisive in housing forming the initial focus of business activities. That led to the establishment of the Runkel Freien Wohnumgsunternehmen – today’s Runkel Treubau – which is successful in the project development and developer field. In addition, Runkel Hochbau undertakes turnkey development of projects in residential and commercial construction as general contractor. Due to its expert, reliable development of construction projects, it is a sought-after partner of small and medium-sized companies for turnkey building projects of every kind. Production and delivery of large-format precast concrete elements such as columns, girders, wall elements and demanding individual building components for trade and industry began with the foundation of Betonwerk Dielfen (today Runkel Fertigteilbau) in 1962 in WilnsdorfNiederdielfen. Some time ago, the decision was made to invest 4 million euros in a thorough modernisation of the precast plant, including new mixing technology, which was supplied by the Kniele company. A stated goal of the modernisation project was high-quality precast architectural concrete elements. Step-by-step to the goal To achieve the stated goal of significant growth in the highquality, precast architectural concrete elements field, Runkel has modernised the precast plant in phases. Firstly, it involved adapting or expanding the facilities for the new requirements and secondly, creating excellent working conditions for the staff. Runkel produces precast concrete elements at two locations. The Siegen company became involved in the new federal states at an early stage. This led to the construction of a second precast plant in Emleben near Gotha. This location has also produced high-quality precast concrete elements since May, 1993. Today, the management team at the head of the Runkel group of companies from Siegen, with its 135 employees, consists of Dipl.-Kfm. Friedhelm Runkel, Dipl.-Ing. Reinhard Willmes and Dipl.-Ing. Peter Körner. Modern, environmentally-conscious production technology and qualified, highly motivated employees serve a supra-regional base of primarily industrial and trade customers. Runkel relies on close ties with its employees. Thus, both Runkel Fertigteilbau plants primarily use their own staff. All of the employees come from the region and have close ties to the company. And with 4 female employees in production, the staff composition is not really typical of the industry. CPI – Concrete Plant International – 2 | 2019 The Runkel precast plant in Siegen

KKM 2250/3375 The mixing principle of the Kniele cone mixer cone mixer is based on a cone-shaped mixing trough. In the first step, the production building was modernised, the work places were equipped with optimised lighting and dark radiator heating created very efficient, comfortable temperatures in the production area. The radiator heating warms the bodies of personnel, but not the air in the hall. This makes it very energy efficient. A conical mixer as the basis for success In the course of this restructuring, expansion of the mixing tower was also essential. Runkel had two essential...

CONCRETE TECHNOLOGY pletely emptied a short time and the funnel-shaped construction is very space-saving. The cone mixer has very diverse applications. Due to independent control of the speeds of both agitators – especially the inner agitator – both liquid and earth-moist concrete can be produced with the cone mixer. Furthermore, according to the manufacturer, this mixer type is also especially suitable for special concretes, such as UHPC und SCC, fibre reinforced concretes, lightweight concretes, heavy concretes, etc. The infinitely variable control enables precise adjustment to the specific...

CONCRETE TECHNOLOGY The mixer empties directly into the concrete bucket, which sits on an industrial truck from WMW Industrieanlagen. Direct access to the control is also possible in production. New tilting tables, column formwork and magnet technology Five new tilting tables from Beta In addition to the new Kniele mixer and the industrial trucks from WMW, Runkel has also invested in additional production equipment, thus comprehensively modernising further parts of production. The Beta company supplied 5 new tilting tables and has completely overhauled the existing tilting tables. The...

CONCRETE TECHNOLOGY Transport of the concrete to both production halls is carried out using industrial trucks. The industrial trucks are automatically directed to the halls by means of points in the track. are fine-levelled and highly polished. The tables can be hydraulically tilted to 80°. The upper part is decoupled from the tilt frame by rubber springs. New column and beam forms from Avermann The Avermann company supplied two columns forms for production of rod-shaped concrete elements. The 15 and 18 m long forms were manufactured as twin forms and are equipped with foundation base forms...

CONCRETE TECHNOLOGY The button-operated magnet from Elematic has a very simple fastening and opening mechanism that can also be used in tight spaces. The magnet can be attached by pressing or stepping. The opening angle is normally 180°, which is why no free area is required around the magnets. This allows the magnet to be removed very easily with the release level. The need for cleaning is minimal, due to the enclosed design. It prevents concrete and other contaminants reaching the interior. ˾ Watch a video about the modernised production at Runkel Fertigteilbau. Simply scan the QR code...
