Bridge Crane load weighing – without loss of headroom

Imagine life without any truck overload fines. No lost time visiting a truck scale because you can weigh everything on your overhead crane.

CraneWeigh is a simple and foolproof bridge crane scale that ensures you meet maximum loading limits. No need to visit a local truck scale, and especially relevant, 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 on the crane, regardless of the position of the trolley and hook on the bridge.

Product features

CraneWeigh bridge crane scale uses the stress in the crane support columns for crane weighing

The CraneWeigh crane scale measures the stress in two opposite bridge crane support columns, which is converted into a weight reading by the indicator. When the bridge is located over these columns, the indicator reads the bridge crane load on the crane hook . . . Read more

L-Strain sensors, as used in our best-selling SiloWeigh products, use high quality metal foil strain gauges, as in load cells.  Because of this design, it gives superior stability and accuracy.  The L-shaped design also compensates for expansion of the metal column. We have demonstrated typical accuracy of ±1 to 2% of full scale when two support columns are used to measure bridge crane weight.

Mount the industrial crane weighing indicator in any convenient location. You don’t have to squint at a display up in the air, and it doesn’t need charging either; it plugs into any convenient outlet.

No loss in headroom for a load cell because the crane is untouched.

It’s simple to install and calibrate the system yourself because we deliver a kit with complete instructions. We provide all necessary cables and we have color coded them to simplify your installation as a result.

You can calibrate it easily, using a known piece weight as reference.  Or you can 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.


Customers, examples

Gainey's Concrete products, near New Orleans LA, installed the first CraneWeigh in 2015. In fact, CraneWeigh was Greg Roache's idea in the first place: at an NPCA meeting he saw the SiloWeigh sensors and suggested we use them for weighing bridge crane load . . . Read more
