MONITOR WEIGHT OF FLYING SHIP
LOAD SHACKLES A
series of 12t and 25t capacity wireless Straightpoint (SP) load shackles are monitoring loads on wire ropes supporting a 2t steel ship, suspended above the city of Linz in Austria, to symbolize the water-themed
Höhenrausch cultural project, which runs from May to October this year. Six 12t capacity and six 25t capacity load shackles
were supplied by SP distributor Pfeifer, which partnered with a local engineering company to create the spectacle atop a parking area in the country’s culture-centric region. Te ship is 21 meters long, 18 meters wide and “flies” at around 81 meters, suspended in part by a wooden tower that was originally erected in 2009 for this exhibition. Pfeifer, a specialist in the provision of ropes for
construction, entertainment, and other projects, said: “Te load shackles constantly monitor and provide information about the loads. Safety is of paramount importance because the ship is suspended above an area where pedestrians view the exhibit. It was a landmark, custom project, befitting of the cultural significance of the event.”
“THE LOAD ISN’T NECESSARILY DYNAMIC BUT WITH WIND SHEAR THE LOADS WOULD CERTAINLY CHANGE… THE LOAD SHACKLES ARE MONITORING THE IN- SITU RIGGING TENSIONS DURING THE EXHIBITION RATHER THAN FOR THE LIFTING OPERATION ITSELF”
Te 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 (orange
in color in the photos) on the ship form the main rigging areas for the complex suspension project. Te load shackles were rigged strategically to communicate data via SP’s Multiple Wireless Load Cell Controller (SW-MWLC) software package, designed for use on a multitude of platforms. David Mullard, business development manager at SP, explained that the operator reads the data on a laptop in a central control station. “SW-MWLC software is used to
