Optimized technology on the basis of tried and tested components

Herrenknecht has been using customized drilling rigs for rock support or geological exploration in tunnel boring machines of all diameter ranges for more than 20 years. The many years of experience with these drilling rigs were incorporated into the development of the new Shaft Drilling Jumbo. The goal from the beginning was to achieve improved performances connected with high work safety for the machine personnel. These prerequisites could be implemented successfully thanks to special adaptations for vertical shaft sinking operations.

The Shaft Drilling Jumbo is used in projects where other methods are reaching their technical or economic limits. Despite its project-specific construction, the machine allows different configurations and flexible drilling patterns and can be used both for blind shafts and shafts with a pilot hole.
