Environmental impact and sustainability are at the top of Dieseko Group's strategy. Therefore, it focuses on optimising high-impact properties such as harmful vibrations, noise and emissions of its machines. Zero-emission is perhaps the most crucial step. Now Dieseko is proud to be developing this electrically powered Woltman machine for BAM Infra.
"The great challenge in our market is the amount of power that must be available during a working day. The amount of power consumed is enormous, and the required battery capacity is comparable to that of around twenty Tesla cars. Therefore, soon, the power supply on the construction site will be crucial," said Ronald IJntema, CCO of Dieseko Group.
The 90DR is the best-selling Woltman drilling rig and the electric 90DR-e offers the same functionalities as an original 90DR rig. As a result, it is also possible to attach an impact hammer and a vibratory hammer in addition to a rotary head. The machine can then drill and drive piles.
The 90DR-e weighs about 105t and measures about 5 x 11m, including the battery pack. The leader's height is 36m and the highest-profile length is 33m. The total battery capacity is over 1MW hour and the used power of the crane is about 600kW.
Over the past months, BAM Infra and Woltman Piling & Drilling Rigs have worked closely together to develop this first 90 DR-e. The electric BAM-Woltman 90DR-e is being built in Giessenburg and will be delivered at the end of 2022.
