Some Montana sites sit in steep canyons or behind terrain that eliminates conventional access. Along corridors like Going-to-the-Sun Road, I-90, and US-93, belt supergroup argillite and glacial till create conditions where the only options are Spider Excavators and rope-access crews.
Access Limited highly skilled team is trained for rope-access drilling and Spider Excavator deployment, reaching places across Montana where conventional drill rigs cannot go. Whether the site is on a steep cliff along Going-to-the-Sun Road, I-90, and US-93 or in a remote canyon, Access Limited brings the equipment and expertise.
Spider Excavators walk from staging areas through the terrain to the work face — no road construction required. On slopes exceeding 60 degrees, these machines drill, excavate, and position materials where no conventional equipment can operate.
When even a Spider Excavator cannot reach the face, rope-access certified crews drill from rope. Vertical rock faces, overhanging terrain, and cliff edges are accessible to these specialty-trained technicians.
Some Montana sites are hours from the nearest staging point. Access Limited deploys self-sufficient crews through the terrain itself for multi-day operations.
Access Limited operates drill rigs fabricated specifically for the confined and steep conditions that Montana terrain demands.
Difficult access drilling supports rockfall mitigation, slope stabilization, shoring, and ground improvement across Montana.
