Speyser, a family-run company from Bas-Rhin, France, has expertise in special civil engineering and well construction. In Lingolsheim, France, wells are being dug with two Sennebogen cranes.
The construction site features a Sennebogen 660 HD duty cycle crane with a casing machine for well construction as well as a 613 telescopic crane used as a service crane to transport and position components and materials.
Christophe Sprauel, Speyser managing director, said, “Several well shafts between 45 metres and 65 m in depth are being dug with a rope grab, using the casing machine that is directly mounted on the duty cycle crane. The diameters are up to 900 millimetres.”
The well is to supply around 300 cubic metres of water per hour later on. The water will then flow down a second shaft again. Thus, a cooling circuit is created. Digging depths of up to 120 m and pipe diameters up to 900 mm are easily possible with the Sennebogen duty cycle crane.
Speyser uses its compact 613 mobile telescopic crane for work in narrow spaces. The 16 tonne telescopic crane pulls the piping elements out of the well drilling and loads them directly onto waiting trucks.
