A reader has sent us a fascinating video of a job in Zams, Austria, the client, a food company building a supermarket and restaurant, had to install a clear span concrete floor into an existing building. Might it also qualify for our Death Wish series though?

The contractor along with crane, lifting and moving company Felbermayer came up with an ingenious solution, although several parts of the job shout Death Wish, in spite of the clearly meticulous planning and innovative solution.

An opening – slot if you will – was made in the façade of the building through which the contractor had to slide the 10 tonne beams. Felbermayer came up with the solution to place a compact city type All Terrain crane on cribbing getting on for around two metres high. This, combined with the cranes jacks, placed the boom pivot point on a level with the slot in the façade.

The beams were unloaded from the street in a tandem lift between the two All Terrain cranes – the other being at ground level. The beams were then slewed towards the building and then telescoped all the way in. A heavy fork truck then took the weight of the bean at the façade end, so that the larger AT could be uncoupled. The remaining crane and fork truck then moved the beam into its final resting place.

The whole job is a pleasure to watch …but… given the number of accidents we see we could not help but notice how many work at height issues there are, from the man uncoupling the crane from the fork truck to those doing the final fit and the unprotected edge. To the most glaring issue that cribbing which resembles a large game of Jenga.
