Measure your load weight – while you are loading

Turn your bridge crane into a crane scale by adding sensors to your support columns.
Craneweigh uses the same sensors as SiloWeigh; L-Strain.
CraneWeigh turns your bridge crane into a scale, measuring each load before it is placed on the truck.
If you can’t use CraneWeigh, here’s a classic crane scale with wireless connection to its indicator

Now you can weigh each item as it is loaded onto your truck . . while it is supported by your overhead crane! CraneWeigh is a simple and foolproof way to verify your truck loading and ensure you meet maximum load limits. No lost time to visit a local truck scale, and the cost is lower than most hook-based crane scales. Just pick up your load and run the crane directly over the gauged support columns; the indicator shows the weight of the piece, regardless of the position of the trolley and hook on the bridge . . .

How it works

  • CraneWeigh measures the stress in two opposite bridge crane support columns.  The indicator converts this into a weight reading.
  • When the bridge is located over these columns, the indicator reads the weight of the load on the crane hook.
  • L-Strain sensors, as we use in our best-selling SiloWeigh products, have high quality metal foil strain gauges, as in load cells, to give superior stability and accuracy.
  • CraneWeigh sensors are temperature compensated by the L-shaped design. We have demonstrated typical accuracies of ±1 to 2% of full scale when you apply them to two opposite crane support columns.
  • Mount the industrial weight indicator in any convenient location. You don’t have to squint at a display up in the air, and it doesn’t need radio or batteries either; it plugs into any convenient outlet.
  • No loss in headroom for a hook-mounted load cell.

CraneWeigh measures the stress in two crane support columns and when the crane is positioned over them, the crane and its load can be weighed.  If the columns also support the roof structure, it is still possible to get good weight readings . . . Read more
  • You need adequate stress in the columns – contact us for details.
  • It only works on steel crane support columns – do not use it on concrete columns.
  • Install and calibrate the system yourself.  We deliver a kit with complete instructions. We provide all necessary cables and color code the conductors to avoid wiring mistakes.
  • Calibration is straightforward, using a known piece weight as reference.  Or call your local scale company  and use their weights.
  • Alternatively, we have trained installation experts at various US and Canadian locations – contact us for details.
  • Not a Legal For Trade crane scale;  accuracy is adequate for loading weight estimation but you cannot use the readings as the basis of a sale by weight.

“Its really accurate, easy to use, improves our safety and it’s a lot less expensive than a conventional crane scale”.  Greg Roache, Gainey’s Concrete Products, August 2018.
