Loads

2000 tonnes

Key Benefits

Provision of a much needed indoor sports and entertainment complex. The sliding roof has been incorporated to accommodate the Hoffman Cup; a world class tennis event played in Western Australia as a lead into the Australian Open.

Drawing  upon their experience of similar projects around the world, the Gantrail design team supplied technical expertise – 89 kg Railtrack and Gantrail 9220/20 clips to secure two rails each side of the Arena for a sliding roof.

This world class entertainment stadium was designed by Perth company Cameron Chisolm and Nicol and was constructed by BGC Western Australia.

Aims

  • To design and build an Entertainment and Sports Arena complex in the City of Perth Western Australia.
  • It will have a seating capacity of 12,000 people for sporting events and 14,000 for concerts.
  • Incorporate a retractable roof which will give an open air facility for sporting events.
  • Attract world class performers and international sporting events.

Timescale

Design was released in 2007 and went through rigorous engineering consultation regarding the capacity of 89 kg rail, the 9220/20 Gantrail weldable base clips and the MKVII Gantrail reinforced rubber pad due to the excessive winds Perth can generate. With the help of the engineering and design staff at Gantrail this was given the go ahead in 2008 for installation.

Installation

The project consisted of;

The rail was joined using an aluminothermic welding process and installed by Vector Engineering in December 2008.

Outcome

The Perth Arena is scheduled to be open in 2011 giving Perth Western Australia a state of the art, world-class sporting and entertainment Arena.

MHE-Demag Vietnam Company Limited

Loads

1000 tonne container cranes

Key Benefits

Project on time and within budget. Dedicated team located on site throughout project duration.

Hutchinson Port Holdings is one of the world’s leading port terminal operators with 51 terminals around the globe. In 2009, they picked MHE-Demag Vietnam to supply and install 1412m of Gantrail Crane Rail Systems for the new Saigon International Terminal Vietnam (SITV) situated in Phu My around 80km southeast of Ho Chi Minh City. The project, worth US$ 800,000 was completed in August 2010.

The scope of work for MHE-Demag Vietnam included the supply of all materials such as rails, sole plates, epoxy rail grout, rail clips, anchor bolts followed by the full installation of the system including rail welding.

The Gantrail crane rails are installed close to the quay, and laid out such that container cranes (ship-to-shore cranes) can move on them sideways along the quay. Each container crane weighs in at approximately 1000 tonnes, putting enormous pressure on the rails especially when in motion. The clips holding the rails and the overall installation in particular had to therefore be executed with exact precision using the best materials available.

Aims

The main aim of the project was to complete the installation within the timelines and specifications provided by the client.

Timescale

Total crane rail installation time from date of contract signing to project hand over was 13 months. The installation was split into 2 phases (600m +814m) with the main focus on phase 1 since the first STS cranes needed to be installed shortly after installation.

Installation

The installation including rail welding was carried out by MHE-Demag Vietnam. Furthermore, MHE-Demag fabricated all sole plates at their own workshop in Vietnam. The complexity of the project required a mix of both local and overseas sourcing for a broad range of materials. The installation took over a year, well within the schedule set by the customer. This was the first ever crane rail installation in a part completed by MHE-Demag Vietnam using its own resources. The team spent 12 months at the remotely located site and had to face both severe heat and wet days during the rainy season.

After completing the first 600 metres, it was a great sight to behold as the first container crane was loaded on to the rails – all ready for operation! The entire 1400 meters was completed in August 2010 with 6 container cranes operating on the rails. A long and complex job had come to a successful end, and team Vietnam looks forward to the next rail job coming on board.

ROI

By working with MHE-Demag Vietnam in partnership with Gantry Railing Limited, Saigon International Terminals Vietnam can be assured of first – class products, installation and after-sales services.

In addition, Hutchinson Port Holdings can as a global port operator and as part owner of SITV trust that Gantry Railing Limited be available wherever in the world supporting Hutchinson at any site at any location.

Street CraneXpress Ltd

Loads

2000 tonnes

Key Benefits

The oldest established Grand Slam tennis tournament can be completed without interruptions from rain.
The beam, rail, translucent cover arrangement allows the cover to be parked so the grass grows well.

Gantrail were subcontractors to Street Crane Xpress who engineered the control technology and mechanical systems, as well as weatherproofing and drainage equipment, for the 5,200 square metre retractable roof over Wimbledon’s Centre Court. This was designed by structural design consultants Bianchi Morley. The roof concertinas so that it can be folded into the ends of the building, and translucent to give the court an open feel when closed.

Gantrail were consulted during the design phase on the best ways of mounting the rails and on the likely deflection of the rails under load. This detail was important for ensuring that the spread of loading between the wheels of the beam end carriages were equally distributed on the four rails. Subsequently Gantrail won the contract to supply and install all the rails and the associated materials.

Aims

Since the first Championships in 1877, the Wimbledon tennis tournament has grown to be the senior Grand Slam tournament with a following of millions around the world. It is the only on played on natural grass and for many years it has been interrupted with rain stopping play. With sporting facilities around the world having stadia with retracted roofs it was time for Wimbledon to act. But the problem of ensuring sound grass growth in sports facilities has been a big problem when sunlight is limited by roof mechanisms.

Timescale

Gantrail were subcontractors to Street Cranes Express. We originally supplied materials for a Mock Up Rail which was built at Stripworth Mills in Rotherham. After successful trials Gantrail were awarded the contract for the supply and install of the complete rail system. This comprised a total of 336 metres of Mrs 87A Crane Rails together with Gantrail 9216/08 Rail Clips and Gantrail MKV11 Crain Rail Pad. The work was completed in time for the Wimbledon Tournament in 2008 after which the installation of the roof itself was completed in time for the 2009 Wimbledon Tournament.

Installation

Gantrail provided supervision, labour, plant, equipment and consumables to install 4 x 84m runs of MRS87A crane rail. The rails were fixed with Gantrail 9216 adjustable clips and mounted on Gantrail Mark VII pad. The rail joints were welded using the puddle or enclosed arc weld method. The rails were installed to the accuracy required in British Standard BS466: 1984 Appendix F.

ROI

The roof was closed for the Wimbledon Opening Event – Centre Court, Sunday 17th May 2009. It was closed in earnest during the first year of its availability although the tournament was fortunately played in fine weather for the majority of the two weeks.
