Fakta om Tovbanen

The zipline was established in 2000. Back then we had a little team-building business, and one day we started talking about how much fun it could be to make a long zipline across the lake.

A 400 meter long rope was purchased and stretched out across the lake between a couple of trees. The first time we tried it out, we had no idea of how fast the ride would be. We just took off. It was really fast, but it slowed down as we approached the water, and the landing was fine.

The zipline was used for a couple of teambuilding events, and in 2001 it was opened to the public for the first time. In the meantime, an extra rope had been purchased which greatly improved safety. It also provided better control, enabling the rider to land feet first.

Over the years, the zipline was further developed. The ropes have always had a tensile strength of more than 6 tons, with a diameter of 8 or 10 millimeters. Harnesses and rope rollers are made by Kong, a brand we sell ourselves. To begin with, trees were used as anchor points, but we now use the cliffs themselves. A seven-ton piece of cliff rock was placed at the bottom in 2002, and the ropes were fastened to it there. The zipline can be put in place by one person without the use of pulley blocks or the like. A brake system was developed to avoid collision with the rubber boat.

The zipline is set up and taken down every day. This was a requirement from the Danish Nature Agency. We think this is a good idea, because it allows us to inspect the ropes at the same time.

There have never been any serious accidents. There have been a small number of injuries. Each time, we have analyzed what happened and how to avoid future occurrences. Among other things, we have changed the instructions several times, but customers sometimes have their minds elsewhere, allowing the instructions take something of a back seat. We have experienced some near-misses due to people swimming under the zipline in the landing area. We have therefore marked off the entire landing area and posted signs prohibiting bathing and swimming under the line. Apart from reducing the risk of accidents, this has also improved the general flow, because we don’t have to wait for swimmers cutting across this area.

The zipline is inspected once a year by Force Technology, which also makes unannounced visits in the summertime. We have been approved without reservation every time.

We do what we can to ensure our customers a good, safe experience.
