Restricted Access Machines
In drilling, limited access refers to limitations that hinder the operator’s ability to use the equipment they have.
A restricted access drilling site is one that is difficult to access in the first place..
Drilling in an urban environment could involve any number of things, from breaking through ground floors to squeezing into tunnels, or even drilling in traffic.
Some sites have only a few square meters to work with, which means a large, conventional rig can’t be used. There is a certain degree of portability with restricted access drilling rigs, making it reasonable for the drill operator to move the rig to the desired drilling site.
