Marko Jaatinen’s Liebherr 900 with its EC20 tiltrotator from engcon has run problem-free for 11,000 hours.
“There are no leaks anywhere. I would never part with this particular combination. I’m sure I can run 20,000 hours with it.
When the 110-year-old lime trees in Jyväskylä Church Park reached the end of their lives, they were removed for safety’s sake. To the amazement of the townsfolk, the roadside trees were replaced within a couple of days with new, 5–8-metre-trees from a nursery. Once they were in place, the new trees looked as though they’d been there for many years.
Marko Jaatinen, in his Liebherr 900, was in full control throughout the whole tree-planting process. The trees cannot cope with any damage to the bark during the sensitive spring growing phase. And replacing damaged trees takes time.
The assignment, like many others, demands precision, flexibility and ability to work in hard-to-get-to areas. In other words, it takes an engcon tiltrotator. And Marko Jaatinen really knows how to operate one.
“Preparing a planting hole of exactly the right size, lifting the tree, planting it in the hole without harming it and backfilling the hole all require precision and controllability,” says Marko, who praises his digger and the tiltrotator.
“It’s already run 11,000 hours; there are no leaks and nothing has broken. When a digger and tiltrotator are built properly and the operator knows what he’s doing, the end result is always good,” declares Marko.
Marko has also built a tree pruner that exploits the strength of engcon’s integrated grab. The tree pruner, which is attached to the grab pins, is easy to install as it can be lifted by hand. It works perfectly for pruning branches or felling trees with trunks up to 20 centimetres thick. It’s all done ’engconomically’.
One of Marko Jaatinen’s assignments is dumping waste from a disused water works. The work in the several-metres-deep pulp basin, which primarily contains natural humus from lake water, requires a long boom. To achieve this, Marko built an extension boom, which he attaches to the bucket pins. This provides several metres extra reach and the wheeled excavator’s stability is ample with just an axle lock. There are no outriggers, and they’re not necessary.
Marko is happy with his Liebherr and its engcon tiltotator. Just over 11,000 problem-free hours have gone by, and Marko is looking ahead with confidence.
“I would never part with this particular combination. I’m sure I’ll reach 20,000 hours without problems,” declares Marko.
