Suspension Bridges, Construction & Design

The Pole Bridge

If you entered through a back door ENTER HERE

We decided not to construct suspension bridges or swing bridges, but to put a pole bridge into place. It gives the user a more secure feeling. Construction was very tricky, as we could not go near the building site with any machinery, and the beams (1000 kg each) had to be "flown in" on a 120 m long steel cable with a diameter of 22 mm. The worst job was to drag that steel cable (300 kg, or 2.5 kg/m) across the valley.


The first pole ready to go, hanging on two rollers and two chain blocks.	We had two reg. engineers on the job, one working and one thinking	The second log is ready to be lowered down.

		Cross beams were prefabricated in the shed and transported on a four wheeler.
The second log is high up in the air, waiting to be lowered down.

The first two cross beams are in place and getting the eye test.
		The beams sit on concrete foundations.
