Over the years, our name has become synonymous with the finest crafted machines in tunneling. First successful employment of disc cutters Each piece of equipment, from our TBMs to our cutters to our SBUs and everything in between, to bore hard rock is engineered for maximum durability and premium...

ROBBINS TEAM ROCK SOLID PARTNERS BY YOUR SIDE When you work with The Robbins Company, you get the most advanced machinery in the tunneling industry and the most dedicated people. While there are no guarantees underground, you can be sure Robbins will be with you at every turn, from machine design through breakthrough and beyond. “We are most proud that LNS has CORE VALUES been able to bring TBMs back to Norway after 22 years since the last TBM project! And the reason we managed to do that on the Rossaga Hydroelectric Project was because of very close cooperation with Robbins.” FRODE NILSEN...

TOTAL COST OF OWNERSHIP SMART INVESTMENT Tunneling is a challenging undertaking. No matter how much you plan, there will always be surprises. The best way to reduce risk and ensure success on your project is to select the best machine for the job and consider the total cost of ownership of that machine. WHAT IS YOUR TOTAL COST OF OWNERSHIP? If you’re basing your choice of machines solely on initial cost, and not taking into account the entire cost of operation and maintenance, you’re not seeing the whole picture. To calculate total cost of ownership, decision makers must consider: – What’s...

MAIN BEAM LONGEVITY The long-running Main Beam TBM now boring the DigIndy Tunnels in Indianapolis, Indiana, USA will have bored more than 50 km by the time it completes the network of tunnels below the city. The machine, originally built in 1980, has been used on at least six different tunnel projects in the U.S. and Canada.

ROCK SOLID STRENGTH Robbins main bearings have the largest ratio of bearing diameter to machine diameter in the industry, meaning that they better withstand the severe eccentric loading frequently encountered in blocky ground conditions. The main bearing and bull gear are separated, giving optimum life for both. The net result is minimized risk with a stronger machine that can be used and reused on multiple projects.

ROBBINS DOUBLE SHIELD AND SINGLE SHIELD TBMS FEAR NO ROCK Fractured rock. Fault Zones. Conglomerates. Dykes. Unstable geology can be an insurmountable obstacle if you’re using the wrong machine. With Robbins Single and Double Shield TBMs, you get enhanced ground support without sacrificing performance. Robbins invented the Double Shield TBM more than 40 years ago. We’ve been leading the industry ever since. Our Double Shield TBMs offer unmatched versatility—back-loading cutters, digital monitoring and guidance, dual-thrust reaction systems—for safe, efficient boring in fractured rock and...

KARGI KIZILIRMAK HEPP | TURKEY A 10.0 m (32.8 ft) diameter Double Shield TBM overcame squeezing ground, fault zones, and fractured rock to bore up to 723 m (2,372 ft) in one month— and significantly outperform a drill and blast heading proceeding from the opposite direction.

ROBBINS EPBS PERFORMANCE UNDER PRESSURE A BALANCED APPROACH When a project’s geology gives you its worst, Robbins Earth Pressure Balance machines (EPBs) give you their best. From electric Variable Frequency Drives (VFDs) to unique smooth flow cutterheads that drive through soft soils, our EPBs are customized to handle the specific challenges of your project. Whether your project is under 7 bar of pressure in sand or just a few meters below the surface in boulder fields, Robbins EPBs are up to the challenge. High capacity main bearing High efficiency Variable makes for robust tunneling and...

CHENNAI METRO | INDIA A Robbins 6.65 m (21.8 ft) diameter EPB triumphed over mixed ground, hard granite rock, and more at India’s Chennai Metro in 2016.

EMISOR ORIENTE WASTEWATER TUNNEL | MEXICO CITY, MEXICO Robbins’ space-saving continuous conveyors haul muck up deep shafts at three mixed ground EPB jobsites in Mexico City.

ROBBINS CONVEYORS MOTION BUILT TO MOVE At Robbins, we know that what lies behind your TBM is as important as what lies in front of it. That’s why our conveyor systems can move more than a thousand tons of muck per hour through kilometers of twisting tunnel, up a 200 m (656 ft) shaft to a stacker conveyor with capacity to store several days’ worth of production. “The soil condition, crew experience, MORE ADVANTAGES, LESS COMPLEXITY rigorous schedule, continuous conveyor, and the reliability of the Robbins TBM are all factors that helped achieve a national record.” VADIM BOCHAROV With a...

ROBBINS CONVEYORS 1. ADVANCING TAIL PIECE The advancing tail piece contains the system’s tail pulley, which includes a protected working window to safely install idler assemblies, all while the belt is still in motion. 2. BOOSTER DRIVE Add supplemental power to your system at specific locations with Robbins booster drives, which properly control the amount of tension in the belt, even through curves. 3. BELT STORAGE CASSETTE Robbins belt storage cassettes can be designed in horizontal or space-saving vertical configurations, and are designed for your capacity needs—whether you need 300 m...
