Murray Slatter, Mayer's Group General Manager, today announced that The Downer Xstrata Alliance have engaged Mayer for the supply of 2 x stackers for its 10.5 million TPA mine. Mangoola Coal is located near Wybong, approximately 20 km west of Muswellbrook and approximately 10 km north of Denman in the Upper Hunter Valley of New South Wales.
Xstrata Mangoola is approved to extract and process up to 10.5 million tonnes per annum of coal from an undeveloped coal reserve at Mangoola for a period of 21 years.
Mayer’s Long standing relationship with Xstarta and Downer follows the performance of the 1600tph Stacker at Mt Owen (1992) and the success of the bid to the performance of the delivery of two stackers (1600tph and 2200tph) to the Geodgevondon mine in the Republic of South Africa commissioned earlier 2009.
The engagement sees Mayer supplying, installing and commissioning a solution to add Downer with 2 x product coal stackers. Key elements of the engagement includes design engineering, supply, electrical integration (Including software/HMI), site erection, commissioning of 2 stackers, storm lock systems, maintenance support systems and anti collision interfaces between, stackers, stockpile, plant and yard dozers.
The machines are rated at 1700tph in a Luffing, long travelling configuration, rail mounted, the machines will handle the product (coal), stacking the coal for export through the underground reclaim system to the rail load out.
Applying the latest Australian and international codes for design, safety, HSE, the design of these machines with further demonstrate Mayer’s leading edge performance on efficient practical machinery.
Tony Fox, Mayer's Sales and Marketing Manager, today confirmed that Mayer's 25 year support of the RG Tanna Facility has chalked up another notch, with the award for the Ship loader 1 Machine room upgrade audit design verification.
Mayer's involvement with the RG Tanna facility extends from having supported this machine since Mayer took over support works from the then PHB Weisehuter. Mayer's founding Father, Hans Mayer designed the machine in 1979 under PHB Weisehuter. Mayer have since designed both Ship loader 2 (1992) and more recently Ship loader 3 (2007).
The Gladstone Ports Authority are committed to upgrading the Ship loaders to keep pace with current operational and safety requirements. This project will see the existing machine audited against AS4324.1 for strength, stability, loading and other relevant codes for safety. The Audit with supply the designers of the upgrade with the detail to support them in the grade design for the installation of a new, larger machine room to support the machines new operational requirements.
Mayer have been engaged by the NSW Roads and Traffic Authority (RTA) to do the last two (of the four, two previously completed) mechanical, structural and electrical 10 year certifications of the Sydney Harbour Bridge North East and North West Arch Maintenance Unit (AMU).
Mayer has been engaged on this project for a number of months and has delivered a result which the RTA had not previously been able to obtain. The AMU's, critical for the maintenance on the Harbour Bridge, faced significant safety issues in operating above the highways and railway lines. Rigorous and considered application of risk assessment and safety standards was the key to achieving the required outcomes.
Mayer confirmed today, further to the 10 year relationship with this bespoke client that we have been awarded the design verification of its 24m thickner. Murray Slatter detailed to the Engineering team that this work represents Mayer's commitment to support firms with specialised solutions to meet its customers needs for their highly specialized equipment. Mayer's commitment to this arena of engineering further details the depth of experience, understanding and diversity of our teams' skills.
Mayer have now audited several such designs for this long time customer, ensuring that these goods, which are locally designed in Australia, have been audited to both Australian and International standards. These particular Thickners are due to be Commissioned in Vietnam later this year.
The company says that on the basis of the international codes compliance, its products have been distributed to 32 countries around the worl
Murray Slatter, Mayer's Group General Manager, today confirmed that the Downer-Xstrata Alliance have engaged Mayer for the design of the impending 10.5 million TPA mine in the upper hunter, North East of Denman.
Both Xstrata and Mayer attributes the success of the bid to the performance of the delivery of two similar stackers to the Geodgevondon mine in the Republic of South Africa, commissioned earlier 2009.
The engagement sees Mayer supply to Downer, 2 x product coal stackers to the Mangoola Mine.
Each machine running on the same rail runway will encompass the following technical states:
- 1700tph Luffing, Long traveling machine
- Rail Mounted
- Anti collision system between machines, plant, stockpile and yard dozers.
Applying the latest Australian and international codes for design, safety, HSE, the design of these machines with further demonstrate Mayer's leading edge performance on efficient practical machinery.
Mayer International has been engaged to design and supply a 2000tph salt shiploader for a local WA Salt Miner.
The client stated that they were looking for a company that could design a machine that fitted into their already existing infrastructure and after hearing of our local Australian capability contacted Mayer to look at their short lead time project.
Mayer recommended a precedent machine as a solution for a shuttling bridge shiploader. In 1996 they designed a radial/shuttling shiploader for the Pusri Fertilizer Company(Indonesia). The client and representatives from Mayer attended site at the Pusri Fertilizer Company(Indonesia) to review the solution, upon which Mayer were engaged.
Mayer is continuing to work with Gladstone Ports Corporation Ltd on the Clinton Wharf Ship loaders 1, 2 and 3, assisting with upgrades, parts supply and technical liaison.
Also, at the Barney Point twin boom stacker, Mayer provided advice and details for the procedure to repair the machine and then followed up with project management for that work.
Currently Mayer has been asked to design the removal procedure for the tripper and pre tripper pulleys for Shiploader 3. Mayer has intimate knowledge of the ship loaders at Gladstone Ports as they are HMIDE (now Mayer International) designed the machines.

Mayer has just completed mechanical, structural and electrical 10 year certification of the Sydney Harbour Bridge south west Arch Maintenance Unit (AMU) for the RTA. Mayer has been engaged on this project for a number of months and has delivered a result which the RTA had not previously been able to obtain. The AMU's, critical for the maintenance on the Harbour Bridge, faced significant safety issues in operating above the highways and railway lines.
