Good Enough

Article by Dennis J. O’Rourke.

A crane must be in good shape to hoist a load. However, challenges arise as crane materials, technology, and accessories advance. The owner is responsible for allowing its use. The reasons for approving a lift are discussed in this paper

The moment a device is placed in use, it starts to wear out.
