High Capacity Crane Scales !

A reasonably priced, high quality crane scale can sometimes be tough to find.

A crane scale consists of a load cell, digital indicator, and cable connecting the two components. The scales need to be calibrated upon inital setup and need to be re-calibrated based on usage and how much they are banged around or moved. Battery options or wireless systems can also be added. There are waterproof crane scales as well.
Low capacity crane scales can be used to weigh anything vertically (or horizontally) from 250lbs to 20,000lbs.
