Equipment & Technology
Symmetrix & InsideAir
We have successfully partnered with Atlas Copco for our rock drilling equipment, and for the Symmetrix system which enables us to simultaneously drill and case the hole. We maintain an inventory of pneumatic hammers and rock bits for drilling 12” to 36” diameter along with the specialized tooling for the Symmetrix system. Through our partnership with Watson we maintain a fleet of Auger rigs which excel in drilling non-rock formations. Our auger bits range from 12” up to 48”. Each of these mobile, truck-mounted drill rigs is efficient in its’ specialized area. Our fleet of equipment is further enhanced with our own InsideAir™. With our InsideAir™ we are able to bring the power of a full drill rig through a standard 30” doorway. InsideAir™ is the ideal choice for any elevator modernization project or existing building renovation. This compact, versatile rig is designed, fabricated and maintained in our own facilities.
We have 200-Ton jacks for removing old cylinders, sanding socks for removing casings broken off below pit floors, bailers in a range of diameters for efficiently cleaning holes to depth and, of course, the drilling equipment necessary for any modification to the existing hole. United Drilling is your sole-source provider for all hydraulic cylinder replacement work. Our 30 years of experience in hydraulic cylinder holes translates into you having the least amount of downtime possible for your cylinder replacement project.
