Steel Ship Suspended in the Air


  • Steel ship weighing 2 tonne made to fly
  • Pfeifer, demonstrates quality of its cable structures and wire ropes in Höhenrausch cultural project
  • 12 – 25 tonne load shackles placed to monitor loads
  • Multiple Wireless Load Cell Controller (SW-MWLC) software package of Straightpoint used to monitor load shackles
  • SW-MWLC enables data to be read on a laptop at a central control station

The Flying Ship

A ship measuring 21 metres long, 18 metres wide is suspended at a height of 81 metres. Apart from the wire rope, the ship is partly held in place by a wooden tower.

Höhenrausch cultural project

As a part of the Höhenrausch cultural project in the city, Germany-headquartered Pfeifer, a specialist in cable structures, wire ropes, and connecting and lifting systems, partnering with a local engineering company in Linz, Austria, have suspended a two-tonne steel ship in the air using wire ropes.

How Two-tonne Ship was made to fly

The hull of the ship was lifted by mobile crane in one piece; the three masts were raised individually and then attached to the structure. Connection points on the ship form the main rigging areas.

Wires monitored

In order to constantly monitor the loads on the wire ropes, Pfeifer is using six 12 tonne capacity and six 25 tonne capacity load shackles from UK-based load cell manufacturer Straightpoint. Pfeifer is also a distributor for Straightpoint products.

The load cells were rigged strategically to communicate data via Straightpoint’s Multiple Wireless Load Cell Controller (SW-MWLC) software package. This enables data to be read on a laptop at a central control station. David Mullard, business development manager at Straightpoint, said, “SW-MWLC software is used to monitor the load shackles for overloads in the rigging wires for safety reasons, as visitors are able to walk directly underneath the flying boat. The load isn’t necessarily dynamic but with wind shear, the loads would certainly change. Unlike many scenarios, here the load shackles are monitoring the in-situ rigging tensions during the exhibition rather than for the lifting operation itself.”

The ‘flying’ ship will be in-situ until October.
