Plant and Equipment

Austrak designs and builds all of its own specialist equipment using its production experience to test the equipment in the field. This ensures the equipment is built for reliability, robustness, efficiency as well as the mandatory parameters of quality and safety. Nevertheless in every production situation each machine is value engineered to ensure that the operation is being done as cost effectively as possible. For example in some countries where labour is less expensive some operations can be done by hand rather than using a dedicated machine.

Broom Oiler Machine: Used to clean and oil the moulds, leveraging the continuous nature of the moulds.

Beds: Frames to house the moulds in the raised and lowered position and provides running rails for the servicing equipment

Moulds: Creates a continuous beam made up of individual sleepers.

Wire Shooter: Sends wire down a track where it is cut to the nominated length.

Wire Trolley: The wire is spooled onto a reel which is used to pay the wire out along the bed efficiently and safely.

Stressing: Hydraulic cylinders, pressure gauges and wire pattern equipment to accurately stress the wires to the correct tension.

Batchplant: The nominated batchmix is generally produced on site to produce the most economical concrete mixture possible.

Casting Machine: The casting machine is designed for maximum vibration to allow the stiffest and therefore most economical concrete mix possible.

Tarpaulin Trolley: Designed for efficient payout of the tarpaulin that allows for low pressure steam curing of the sleepers.

Steam Generators and Control: Steam generators create the steam for injection under the bed. The system is generally PLC controlled for accurate data logging and control to prevent any chance of delayed ettringite formation.

Demoulder: The demoulder removes the moulds from the sleepers and allows the insertion of a bed trolley that supports the sleeper in lieu of the mould. It also gently lowers the mould into the lowered position to prevent damage and ensure long mould life. The demoulder is also used to lift moulds into position once the sleepers are clear in readiness for the next casting.

Bed Trolleys: Bed trolleys support the sleepers once the mould has been removed. The entire trolley/sleeper assembly is then winched into position in readiness for the saw cutting.

Saw: The concrete saw is used to cut the sleepers and rotate the sleepers 180 degrees for inspection. The inspection procedure may use a single line conveyer to allow a single person to inspect and install any fastenings on the sleeper.

Finished sleeper handling: The sleeper is then transferred to a roll bed where it can be collected by either gantries or forklifts. Pack configuration is given special attention so it matches client requirements, negating double handling and improving sleeper quality.
