Overhead crane and hoist owners in the United States normally do not knowingly put their workers at risk. But it is what you don’t know about the design life of equipment installed in the last 30 years that may, in fact, pose a considerable risk to the safety of your people.
In the last 30 years, the average weight of a standard 5 Ton Capacity Wire Rope Hoist has dropped in weight from over 1000# to as light as 500# in the current versions being sold. Although both hoists will pick the same load, they likely differ in the ultimate finite life period of the unit. Many of the newer European style hoists are produced with only a 5-year design life when used at the maximum of the specified load spectrum. Since many of these hoists have been installed and in use for over twenty years, there is great cause for concern.
