Tyrolit drilling system used successfully on underwater project
Published 24/11, 2021 at 16:59For two months at the beginning of 2021, an artificial lake in Milan, Italy, was the setting for the use of Tyrolit drilling equipment. The task was a demanding one as in a first step, 32 holes had to be drilled and then poles had to be inserted to serve as a mooring point for boats close to the shore. The contractor of the project was Expertagli Aosta, a subsidiary of the Edil Taglio Cemento Group, which is well known for professional drilling and cutting works in northern Italy. For this demanding job, the company decided to rely on Tyrolit equipment, as it was not feasible to be carried out with conventional machines.
Particularly challenging was the fact that the work had to be carried out in a water depth of 4m to 5m with the visibility underwater being very poor, with another challenge arising from the sediment on the bottom of the lake. For this reason, the use of Tyrolit special tools and machines was decided upon. In total, 32 holes with a dimension of 350mm x 4,000mm had to be drilled. With a capacity for diameters up to 1,000mm and with an optimised drill bit attachment for larger diameters, the DGB1000 drilling gearbox from Tyrolit was the ideal tool for this project. The DGB1000 was supported by the 25kW PPH25RR drive, providing optimum cutting speeds with its four stage control.
The project was completed successfully within two months and the Tyrolit machines proved to be ideal for versatile and complex tasks.
