For the new track installation, the original rail was first cut at the S4 southbound and S7 northbound ends, then the new tracks were installed and connected to the existing rail using the thermite welding. Detailed thermite welding procedures are described in Sec. 3.2. Fig. 5c shows the test site after the sliding slab track installation.processing of new rails (removal of decarbonised peripheral layers, removal of profile deviation and cold damages) for newly installed switches efficiently and with highest quality. With help of LINSINGER high performance milling technology the unplanned, premature removal of …

ARTC Announces a Timber Resleepering Program for Western Main Lines. Australian Rail Track Corporation Ltd (ARTC) will install 61,732 timber sleepers this financial year on its Western rail corridor between Kinalung and Broken Hill in a project valued at $8.27 million, David Marchant CEO of ARTC announced today.This strategy is suitable for a newly installed rail ground to correct profiles or rail that has been recovered by S2–S4. [17]. By slowing down the machine, increasing the grinding motor ...

Furthermore, ejection methods may be designed which do not require any operator involvement after the machine starts to function. Some feeding and ejection methods may even create hazards themselves, such as a robot which may eliminate the need for an operator to be near the machine but may create a new hazard by the movement of its arm.True Gear's NILES ZP 12 will allow them to grind internal and external gears up to 1.2 meters in diameter. Dual dressers reduce dressing time and gear inspection is on the machine. Also, with the new ZP 12 design, optional software makes worm grinding possible too. Mark says, "We have had our ZSTZ 315 in production for close to 20 years and ...

System and method for abrading radioactive contaminants from the inside surface of a pipe. The system includes a nozzle block capable of mixing a liquid and an abrasive grit into a suitable liquid-abrasive grit cleaning composition and impinging the cleaning composition against the inside surface of the pipe. The system further includes an inflatable torus-shaped seal for confining the liquid ...Creation of the access area 128 allows new piles (not shown) to be installed through the rail assembly 102 and allows new pile caps (not shown) to be positioned on top of the new piles.
