What are the differences between dynamometers and crane scales?
The most noticeable difference between a dynamometer and a crane scale would be the presence of shackle at the top and bottom of a dynamometer while a crane scale features a hook on the bottom.
Crane scales are more suitable for vertical load and weight measurement and dynamometers can be used to measure load and tension in any direction. Due to their low weight and compact dimensions dynamometers are more portable and therefore more suitable for on-site/field work. Dynamometers can be ordered with an optional carrying case.
