Overhead weighing is a very useful feature for any facility, giving you the power to test and weigh a large variety of objects.
These tools will allow you to measure and maintain just about anything with ease. Digital monitors with wireless remote controls are very easy to use and convenient, helping you get the job done quicker. This makes them perfect in high-action environments. We also have larger models that can handle the toughest jobs, with large capacities that make them perfect for industrial-sized tasks.
Digital crane scales will make your life easier by helping you make measurements quicker and with less stress. With inaccuracies as low as .2% or better, these tools are as precise as any standard force gauge and will give you readings you can rely on every day. With the durable aluminum design, they can hold up to the rigors of industrial use and withstand the abuse of highly active environments.
This means that our crane weighing scales will continue to perform, years after their first use!
Crane scale calibration and service
A crane scale is a force-measuring device that hangs in the load path. Shock loads, side loading and overloads can shift its accuracy without any visible damage, and many crane scales are used to check loads where errors are costly. Instrument Calibration Solutions (ICS), a Brechbuhler Scales company, calibrates crane scales and issues digital certificates through ScaleSuite, available 24x7.
What we check on a crane scale
- Accuracy at several load points across the range, in increasing and decreasing steps
- Repeatability and return to zero after load is removed
- Hysteresis: whether the scale reads the same going up as it does coming back down
- Load cell body, hook, shackle and swivel condition, since bent hardware changes how the load is carried
- Display, battery, and remote or wireless indicator performance
Why crane scale calibration is a force calibration
Because a crane scale measures tension, it can be calibrated against force standards as well as weights. Force calibration practices follow standards such as ASTM E74 and ISO 376. Our labs also calibrate load cells and other force devices, so a crane scale can be checked to the same discipline. See our force measurement and calibration page for details.
Calibration does not replace lifting inspection
Calibration confirms the scale reads correctly. It does not certify the rigging, hooks or lifting equipment it hangs from. Follow your own inspection and safety program for lifting gear.
Signs your crane scale needs attention
- Readings drift or do not return to zero when unloaded
- The same load weighs differently on different lifts
- The scale was overloaded, dropped or shock loaded
- The hook, shackle or load cell shows bending or wear
- A customer or auditor asks for calibration records
Crane scale calibration FAQs
How often should a crane scale be calibrated?
Many companies calibrate crane scales annually. Heavy use, shock loads, or an overload event call for a sooner check.
Can a crane scale be legal-for-trade?
Some crane scales are approved for trade use and are covered by NIST Handbook 44 and state weights and measures programs. Many are used only for internal weighing. Tell us which applies to yours.
Do you calibrate the remote display too?
The display and the load cell work together as one system, so both are checked. Include the remote or handheld unit when you send the scale in or schedule a visit.
What information should I have ready?
The make, model, capacity and readability of the scale and how it is used. This helps us confirm the load points and approach.
Where can I find my crane scale certificates?
Certificates are available online at any time through ScaleSuite.
