“It’s a very smooth way to load,” says Rune Lien, Project Manager at BetonmastHæhre. “The alternative would be to drive to and fro with loaders, which would take much longer and cause more wear to both the road surface and the machinery. And since the Häggloader is a continuous loader, it’s easy to fill the dumpers optimally.”
The Häggloader is mainly electric-powered, with diesel required only for lengthy tramming. This reduces climate impact and lowers noise levels, as well as reducing ventilation costs.
“The Häggloader requires a ventilation capacity of 16–17 cubic meters a second,” says Rune Lien. “Had we used a diesel loader instead, it would have needed to be at least 40 cubic meters a second. Something like that would have required larger tunnels – and since we’re doing so much tunneling, the costs would be considerably higher. And all for nothing, because there would be no benefit in terms of what’s finally delivered.”
On certain sections in the rock there are steep gradients of up to 15 percent. A wheel loader would find it difficult to work in such conditions – but for the Häggloader, which does not move and scrapes down the material onto the conveyor, it’s another matter.
“The machine is incredibly good on a gradient, and it’s also multifunctional. I use the boom not just for loading, but also to scrape the walls and roof of the tunnel. And moving the machine sideways at the tunnel front is easy because it’s equipped with front and rear steering,” says operator Ole Jørgen Johansen, who has been working with the Häggloader for four years.
He continues:
“It’s also nice not to be moving about when you’re loading. Driving a wheel loader to and fro can be quite bumpy, but this is much gentler on the back. We’ve even been given air seats, which makes the working environment even better.”
BetonmastHæhre is to complete the project at the end of 2019, and to date the work has gone according to plan. Combining a wheel loader – as used at the loading bays placed at 200 meter intervals in the rock – with the Häggloader has proved to be a winning concept.
“We’ve tried other solutions in previous projects, but no loader has delivered like the Häggloader,” sums up Rune Lien.
