Multi-purpose platform for tunnel driving

摘要

Multi-purpose platforms for underground tunnel driving essentially consist of a vertically adjustable and longitudinally displaceable main platform which is provided with a support manipulator, a means of securing the heading face and also at least one drilling cradle pivotable on all sides. So that a multi-purpose platform can be effectively braced in any position relative to the support system while remaining stable and can at the same time advantageously direct the forces to be absorbed into the support system, the invention provides for the main platform (1), having a secondary platform (2) extendable towards the heading face, to be arranged in a frame-like structure (5) which is adapted to the supported roadway (3), can be braced against the support system (4) and can be moved in the longitudinal direction. <IMAGE>
