Spider Excavator Services for Steep Slope Drilling & Stabilization

Spider Excavators are all-terrain, “walking” machines designed for steep, limited-access environments—including mud, snow, rock, and active streambeds—where traditional tracked equipment can’t operate. Access Limited operates the nation’s largest and most advanced fleet of these rigs, each outfitted with purpose-built drill attachments for mechanical scaling, high-angle excavation, and the installation of SuperNails®, rock bolts, micropiles, and tensioned anchors on slopes up to 70 degrees.

Faster Access, Steeper Slopes, Proven Savings

Traditional contractors often spend weeks cutting access roads before drilling can even begin. At Access Limited, our Spider Excavators “walk” directly onto slopes—up to 60 degrees—eliminating the need for road construction and enabling immediate drilling of soil nails and rock bolts. This approach reduces project durations by up to 80% and delivers comparable cost savings to the client. Backed by the most experienced operators in the geohazard industry, our team is equipped to respond rapidly to emergency landslide repairs, rockfall mitigation, or foundation grouting projects—no matter how steep or remote the terrain.
