Dive Brief:

• At a construction site where a one-story indoor-sports building is being erected at a business in Abilene, Texas, a telescoping-boom crane was being used Monday to put an air-conditioning unit onto the rood when the load dynamics got to be too much, and the crane boom wound up on the building.
• The unit, owned by Crane Service Inc., had its outriggers extended to the sides, but it was facing nose-in to the building and lifting along that axis when the weight and the extension surpassed its stability limit and the rig pitched up onto its nose.
• The boom dented the side of the building, and officials of the company that owns it, Prime Time Family Entertainment, said the AC unit landed in the right place, but landed too hard to be usable.

Dive Insight:

The accident shows that there is always a fine line beyond which any combination of weight and reach becomes unstable. No one was hurt in the accident Monday.
