Kiwi creation for tower cranes unlocks export potential & dodges diesel.

Look at any city skyline and you’ll see…tower cranes. It’s estimated over 100,000 of the mechanical monsters operate around the world, many powered by air-polluting, diesel-powered generators or large transformers connected to the grid.

But a Kiwi invention, manufactured by a team in a warehouse on Auckland’s North Shore, is leading the world in replacing the dirty, noisy machines with clean, sustainable and quiet electric battery-powered generators.

It’s a 21st century technology take on our No.8 wire history of inventions. Elliot Peacocke, an engineer who used to rent out those old-school generators, had an idea while working alongside the Rocket Lab team – and later built the prototype.

As history has proven, many good ideas never make it to fruition but Peacocke had the good fortune to pique Kiwibank’s interest. As Tom Williams, the bank’s Head of Sustainable Finance, says Peacocke’s idea was “true Kiwi ingenuity - having an idea, going about solving it and then building it. What Elliot wanted was to make something better than what was there before and for everyone to get on board with that.”

In 2014, Peacocke started Nukor to import, sell, rent and service diesel generators and industrial air compressors. In 2015 he began working alongside Rocket Lab, among other companies. After Nukor was contracted to build the power system for Rocket Lab’s Mahia launch site, Peacocke later returned to his idea of creating a battery alternative to fossil fuel generators.

“I saw that tower cranes use a whole lot of power for very short periods, so you end up running these large diesel generators all day long, just waiting for little spikes of power. It struck me as being really inefficient; I thought there must be a better way to do it, with batteries.”

“There are over 100,000 tower cranes in operation around the world and providing power to them is getting harder and harder for construction companies. National grids are under more and more strain, diesel prices are going through the roof and there’s ESG pressure.

“Everything reached a point where I thought, ‘this is a great idea and I want to commercialise it’. I sold Nukor in 2021 and put all the money and all my time into Cranepower.”

For Kiwibank, Cranepower ticked the boxes for innovation, clear commercial purpose and sustainability and Peacocke says the relationship with Kiwibank throughout Cranepower’s short history has been crucial.

“Kiwibank have been really supportive since day one. For instance, they helped us to finance the building of our rental generators assets that are currently in market - they went out on a limb because they were a new kind of asset and they weren’t really sure what the demand was like. That they could see the obvious benefits of the product and went, Yep, we’re going to support this, has been a huge help.”

Smith Cranes, the country’s largest crane company, jumped at the opportunity to buy the first machine. Cranepower rents units to Kiwi construction companies. Peacocke launched in Australia last year with units on the ground there and many more projects seriously considering using his machines.

Next stop, the world. “The total addressable market for our existing product is somewhere around $US3 billion and we’re the only people making them at the moment.”

Williams points out there are around 1000 tower cranes at work in New Zealand and Australia at any time, most across the Tasman.

“If we can help him get into that market, get more of these units out there, not only does it help them scale up and prove the technology, but every single one of his units that go around Australia, around New Zealand, are reducing diesel consumption, reducing emissions and reducing noise.

“That’s a good outcome for everyone near the construction site and it’s a good outcome for the Kiwi economy because we’ve got a high-value high-tech product being exported.

“New Zealand needs to grow these high-value export products. We can’t rely on what we’ve done in the past as we look to the future. We need more businesses that might be creating new software or creating a new product like Elliot has, that the world is going to need - and can help fuel the Kiwi economy and the next generations.”

There’s a challenge. Global construction companies know only two ways to power tower cranes: a huge transformer connected to mains power or a large diesel generator.

“We’re having to educate construction companies about this new third option and it’s taking time for people to get comfortable with it. We think that will grow exponentially as larger players start using our machine.”

Benefits, Peacocke says, are obvious and wider than commercial considerations. “We have a triple whammy packed with our product. I’m always a fan of products or solutions that tick all the boxes - often there’s these so-called ‘green solutions’ which are not very practical and don’t stack up commercially.

“Our option is much easier, smaller and quieter to use; it’s much cheaper because you don’t have to keep filling the generator with diesel and you don’t have to spend hundreds of thousands to put in a transformer.

“Environmentally, it’s much better than burning a whole bunch of diesel. One of our machines can save up to 200 tonnes per year of CO2, which is the equivalent of around 100 EVs on the road.”

Williams says the strength of the relationship between Cranepower and Kiwibank is that they’ve been together from the outset – and that’s crucial.

“Right from the start, when Elliot was creating his concept, he formed a relationship with two business bankers in particular. They’ve been with him all the way. Knowing your banker really does matter in business banking.”
