Lincom Warrior helps build port

The Lincom Group has supplied machinery capable of processing more than 2.6 million tonnes of material to expand one of New Zealand’s biggest ports.

The Lincom Group has supplied machinery capable of processing more than 2.6 million tonnes of material to expand one of New Zealand’s biggest ports.

Lyttelton Port Company (LPC), the largest port on New Zealand’s South Island, began a long-term project to develop a new modern container terminal at Te Awaparahi Bay.

The port had forecast an increase in the region’s future container trade and decided to expand to meet changing customer requirements.

In order to do this, it needed to reclaim land below the line of high tide. It began a two-year land reclamation project, contracting C&R Developments to begin dredging a section of seabed and replace it with engineering bund containing around 850,000 tonnes of selected material, extracted from a nearby quarry.

The overall project had a number of stages, with the soft sediments needing to be removed before the bund could be constructed and tipping of material could begin. A combination of blasting, excavation, screening, stockpiling, carting and placing of material was required, with more
than 2.6 million tonnes of material needed
to extend the port by six hectares.

LPC also deployed an environmental management plan for the reclamation, to help minimise and mitigate any environment impacts and support the ecological health of the harbour.

More than 2.4 million tonnes of earthquake demolition material and rubble went into the reclamation, much of it is from buildings in Christchurch demolished after the earthquakes. This saved Christchurch and the region more than NZ$100 million in dumping costs and provided fill for the reclamation.

C&R Developments owns and operates a selection of heavy plant which is able to manage some of the toughest and most demanding jobs. The company takes pride in its capability to handle big jobs and says that no challenge is too great when it comes to completing major projects on time and within budget.

To help C&R undertake this massive project, it worked closely with the Lincom Group, a material processing equipment provider with experience in the mining, quarry and recycling industry sectors.

After discussing the specific requirements, Lincom delivered a heavy-duty screen machine called the Powerscreen Warrior 2400.

The Warrior 2400 has been specially designed for large-scale operators in the quarrying and mining sectors and is capable of handling larger feed sizes and throughputs. It features a heavy-duty screen with a high amplitude triple-shaft drive mechanism, lending it to the most demanding screening, scalping, two- or three-way splitting and stockpiling applications.

“C&R needed big tonnage for the Lyttelton Port project and the Warrior is the biggest scalper on the market,” says Catrina Quinn, Lincom Group Marketing Manager. “It is 20’ x 6’ (6m x 1.8m) on both decks, top and bottom.”

“The Warrior 2400 is different to everything else on the market. It’s the only scalper with triple-shaft technology, meaning both the amplitude and the direction of throw can be altered – and independently of each other.

“This gives the ability to accurately tune the machine to the specification application, maximising quality and throughput of the finished product.”

Other features include a slide out tail conveyor facility to aid media access and a load sensing collection conveyor circuit to avoid blockages.

Additionally, the Warrior 2400 has an output potential up to 800 tonnes per hour, an aggressive heavy-duty triple shaft screen, with adjustable frequency, amplitude and stroke angle and a jack-up screen facility to aid screen media changes.

Lincom has also taken steps to ensure the safety of persons and the proper functioning of the plant, with codes of practice assisting with the risk assessment of the machine during commissioning.

Ms Quinn says Lincom focuses on safety and efficiency of production to maximise the return on investment for its customers.

“Anywhere, anytime, no matter the location, time or situation, we pride ourselves on delivering the right solution and after-sales support,”
she says.
