RWE Power AG in Hamm, Westphalia, is investing around EUR 2 billion in the construction of one of the world’s most efficient coal power plants with a total output of 1,600 Megawatts. The placement of around 250,000 m³ concrete of different property classes and consistencies is predominantly carried out using Putzmeister truck-mounted concrete pumps with up to 62 m placing boom height and two stationary PM placing booms.

A Telebelt TB 130 telescoping conveyor belt is also used on the vast construction site to deliver the different bulk materials.

The client has commissioned ALPINE Bau Deutschland AG (Industrial and Power Plant Construction) with the execution of the extensive earth, concrete and construction work for the two new power plant blocks “D” and “E” (order volume EUR 135 million).

The order to deliver over 220,000 m³ of concrete was received by the concrete pumping service BEKA. Crucial in the assignment was the fleet, which consists of over 40 truck-mounted concrete pumps. In addition to machines from the 20, 30 and 40 metre class, BEKA also has three M 52-5s, three M 58-5s and two M 62-6s. The two-block power plant with 2 x 800 megawatt power is being constructed on the site of a previously planned nuclear power plant and next to the high temperature reactor THTR-300, which has been shut down since September 1989.

The construction of the new power plant includes a building complex of engine and boiler houses, switching system buildings and water centre, four stair towers, seven silos with up to 10,000 m³ capacity for limestone, cement and ash as well as two 165 m high cooling towers.

    Fleet Mix Crucial

The order to deliver over 220,000 m³ of concrete was received by the concrete pumping service BEKA. Crucial in the assignment was the fleet, which consists of over 40 truck-mounted concrete pumps. In addition to machines from the 20, 30 and 40 metre class, BEKA also has three M 52-5s, three M 58-5s and two M 62-6s.

Due to the vast boom lengths and large working range, placement was made possible by flexible 5 and 6 arm technology. BEKA’s long-reach boom pumps gave it a crucial advantage in the invitation to tender. In addition, there was the possibility of supporting the large 5 and 6-axle trucks in OSS mode on one side, if the construction site conditions allow for this.
