5000 Series Pump Unit System

5000 Series II Pump Unit System: Design G Goals Better specifications equating to increased efficiency Improve ergonomics Compatibility I Improve safety for operators f t f t Integrated dual -feed pump Same dimensions Improved component availability Improve aesthetics

5000 Series II Pump Unit System: Enhancements Simplified Design p g Two independent hydraulic systems Integrated dual-feed capabilities while keeping same height dimension as the single-feed 5000 Overall dimensions changed by 10” of added depth

5000 Series II Pump Unit System: Enhancements Extended vertical clearance for laser Improved operator’s station- eye level gauges and indicator lights-hand level hydraulic co t o s d cato g ts a d e e yd au c controls Lower noise levels, electric motor for cooling circuit eliminated Phase connection error indicator light Two reservoirs one for high and one for low pressure

5000 Series II Pump Unit System: Enhancements Overall improved hydraulic plumbing resulting in fewer leaks Easier to service New operators can be trained quickly Series II unit is compatible with all existing Akkerman TBM’s, Haul Systems and jacking yokes

5000 Series II Pump Unit System 400 Tons of Jacking Force Diameter Range 36”-144” 120 GPM @ 3000 PSI Hydraulic Dual Feed, standard on y Series II TBM Original 5000 required an auxiliary pump to achieve dual g q yp p feed-increased height clearance IJS hydraulic p y pressures were reduced from 8400 PSI to 5800 PSI which will require the use of more IJS cylinders.

TBM vs. Slurry Microtunneling Tunnel Boring Machines (TBMs) Slurry Microtunneling The TBM is accurate, installs a wide range of pipe sizes in varied geology, low cost of operation and with minimal training, face access for cutter head service and obstruction removal, not water tight Slurry microtunneling requires a higher initial investment, experienced crew is necessary, use is diameter dependent, no face access, water tight shaft with pit seals installation Diameter Range Passive, laser Guidance System Active, laser Minimum Shaft Size Conveyor and haul unit system C Slurry separation...

Tunnel Boring Machine - Series II: Design Goals G Better drive reliability Increased torque Capable of excavating mixed ground conditions as well as soft ground and soft/weathered rock Bi-Directional Rotation, variable speed cutter head rotation Improved operator ergonomics Simplify the hydraulics and minimize leak points Improve aesthetics Easier to build

Tunnel Boring Machine - Series II: Enhancements Fully sealed and lubricated tri-roller bearing-equating to better drive reliability Motors capable of 5,000 psi high-pressure, producing higher torque q Series II TBMs offer 40% more torque than first series TBM’s Simplified Hydraulic System

Tunnel Boring Machine–Series II: Enhancements Operator Safety: machine e-stop Improved ergonomics- controls are centrally located and p g y easier to operate Robust construction for the expanded range of g p g geology gy the machine is capable of excavating and increased distances projects are requiring.
