Spider Excavator Services for Steep Slopes

Spider Excavators are all-terrain, “walking” machines built for steep, limited-access sites, including mud, snow, rock, and even active streambeds, where traditional tracked equipment can’t operate. Access Limited operates the largest and newest fleet in North America, each outfitted with custom 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 begins. Our Spider Excavators can “walk” directly onto slopes up to 60 degrees, eliminating road construction and allowing immediate drilling.

This approach can cut project durations by up to 80% and deliver significant cost savings. With the most experienced operators in the industry, we mobilize quickly for landslide repair, rockfall mitigation, and foundation grouting, even on the steepest, most remote terrain.

Reliable Project Support in South Dakota

Cameron, I’m glad you followed up because I don’t do a good job of telling people they did a good job sometimes and I know you’re like me if you hear nothing bad then it must have been OK. From my standpoint, you guys really helped us out by being able to get a crew here quickly which is just what we needed. As for the crew they were fantastic, pretty hands off on my end, didn’t require much of my time and did everything they said they were going to do when they said they were going to do it. Which believe me is very refreshing. So, thank you guys for all your help and I do look forward to an opportunity to work with you again.

Slope Stabilization in Virginia

I’d like to take a moment and thank you for sending a great crew for the stabilization at [our site]. With the leadership of Dylan Battaglia and his crew, safety was always incorporated in each task that was performed. Dylan communicated each phase with [our company] and also gave great instruction to all his employees during the JSA process. Great job!

I’d like to ask if you could send the same crew back for the final phase of the project and wrap the project up in a positive manner. Thanks again for a job well done, and wish you and your family the best of the holidays. Please give your crew my best.
