TUMI Raise Boring SBM raise boring machines and drilling tools

Stationary and self-propelled SBM raise boring machines, the SBM 21 BX box hole machine, reaming heads, cutters and drill pipe by TUMI. Selection by raise diameter and length, quotation per project.

SBM 300 and SBM 400 stationary raise borers

Stationary SBM 300 and SBM 400 machines with hydraulic drive and low profile bore raises up to 1.5 and 2.1 m in diameter and 150 and 380 m long at 45° to 90°. Variable rotation speed at constant torque adapts to ground conditions. Main motors give 112 and 150 kW, reaming thrust 610 and 1,570 kN.

Diameter up to 2.1 m
Length up to 380 m
Torque 35 and 80 kN·m
Pipe Ø203 and Ø254 mm

SBM 700 and SBM 800 XP heavy raise borers

Heavy SBM 700 and SBM 800 XP machines bore raises up to 3.6 and 6 m in diameter and 450 and 1,100 m long. Main motors give 224 and 300 kW, reaming thrust 2,960 and 7,000 kN and torque 163 and 416 kN·m. The SBM 800 XP comes on a crawler and runs Ø286 and Ø327 mm drill pipe.

Diameter up to 6 m
Length up to 1,100 m
Torque up to 416 kN·m
Thrust up to 7,000 kN

SBM 400 SR and SBM 700 SR self-propelled raise borers

Semi-automatic self-propelled SBM 400 SR and SBM 700 SR machines need two operators. The SBM 400 SR self-levels and locks into the drift electro-hydraulically and needs no concrete platform. The SBM 700 SR moves between jobsites on its own track. Reaming thrust is 1,470 and 2,960 kN.

Two operators
No concrete platform
Thrust up to 2,960 kN
Weight 18,500 and 31,800 kg

SBM 21 BX box hole machine

The SBM 21 BX drills upward from the lower level to the upper level without excavating a complete shaft. Two people run the semi-automatic machine, transport is remotely controlled, and hydraulic cylinders level and secure it. It has a 75 kW main motor, 600 kN thrust and 15 kN·m torque.

Dip angle 45°–135°
Weight 26,000 kg
Pipe Ø254 mm × 0.91 m
Remote-controlled transport

Reaming heads, cutters and drill pipe

TUMI makes reaming heads of all diameters, cutters, drill pipe built for high torque and tensile stress, stabilizers and bit rollers for the pilot hole. The stem attaches the reaming head to the drill string with a DI-22 threaded connection. Hole openers serve box hole and down reaming.

Lifting sled, track runner and automatic disconnection

The hydraulic lifting sled raises and lowers the machine for transport and installation. The Runner track conveyor saves time moving between jobs. TUMI automatic disconnection grips and releases drill pipe with mechanical clamps from the console, removing manual handling of parts of about 30 kg.

How to choose a TUMI machine

Selection of a TUMI machine starts with the excavation method. For raises with a pilot hole and upward reaming there are the stationary SBM 300, SBM 400, SBM 700 and SBM 800 XP or the self-propelled SBM 400 SR and SBM 700 SR; for upward drilling from the lower level there is the SBM 21 BX.

Next, the machine is matched to raise diameter and length: SBM 300 up to 1.5 m and 150 m, SBM 400 up to 2.1 m and 380 m, SBM 700 up to 3.6 m and 450 m, SBM 800 XP up to 6 m and 1,100 m. Self-propelled SR machines move on their own: the SBM 400 SR needs no concrete platform, and the SBM 700 SR runs on an integrated track.

SBM machine data

Main motor power runs from 75 kW on the SBM 21 BX to 300 kW on the SBM 800 XP. Reaming thrust is 610 kN on the SBM 300, 1,570 kN on the SBM 400, 1,470 kN on the SBM 400 SR, 2,960 kN on the SBM 700 and SBM 700 SR, and 7,000 kN on the SBM 800 XP. Torque runs from 35 to 416 kN·m.

Variable rotation speed at constant hydraulic torque adapts to ground conditions. The semi-automatic SR machines and the SBM 21 BX need two people to operate.

Drill string and reaming heads

TUMI makes reaming heads of all diameters, cutters, drill pipe, stabilizers, pilot hole bit rollers and stems with a DI-22 threaded connection. Drill pipe is Ø203 mm on the SBM 300, Ø254 mm on the SBM 400, Ø254 and Ø286 mm on the SBM 700, and Ø286 and Ø327 mm on the SBM 800 XP.

Stationary machines move on a hydraulic lifting sled and the Runner track conveyor, and automatic disconnection handles drill pipe with mechanical clamps from the console.

The manufacturer

TUMI was founded in 1998 in Peru as a raise boring contractor and has built its own machines since 2010. The company is part of TIG; TUMI Raise Boring has its office in The Woodlands, Texas, and its plant in Lurín, Peru.

At the Raura mine an SBM800 bored a 410 m ventilation raise 4.3 m in diameter at 4,850 m above sea level.
