Checking crane-hook loads with a hanging scale (workshop notes)

Disclosure: I work with CraneScale (https://cranescale.co.uk). This post is practical notes from using hanging crane scales on UK workshop lifts, not a product launch.

Why bother

When you lift crates with a hoist, the label weight is often wrong. A hanging crane scale between the hook and the load shows what is actually on the hook before you commit to moving it. Useful for spot-checks, comparing batches, and staying inside the hoist rating. It is not a substitute for a legal-for-trade bench scale.

Pre-lift checklist

  1. Capacity above the expected load, with margin.
  2. Inspect shackle, hook latch, and upper eye.
  3. Zero / tare with no load.
  4. Keep the load path vertical — side pulls skew readings.

Getting a stable reading

Lift just clear of the floor and pause. Wait for the digits to settle. Swinging, gusts, and soft slings make the value bounce. If it hunts, lower, re-centre the sling, try again. Log the stable value, not the peak flicker.

Mistakes I still see

  • Reading while the load swings
  • Using a damaged shackle for a "quick check"
  • Ignoring low-battery warnings mid-lift
  • Trusting the crate sticker without a spot check

Care

Wipe grit, store dry, protect the load cell from shock. After a drop or overload, take it out of service until checked.
