Crane scales FAQs
What is a crane scale?
Sometimes referred to as a hanging scale, a crane scale is a specialised, precision weighing device used to weigh large, heavy items suspended from cranes, hoists, and overhead beams. Knowing the real-time weight of your large or awkwardly shaped suspended loads is important, as it ensures you don’t overload a lifting device or a crane.
How do crane weighing scales work?
Crane scales are typically attached between the crane’s hook and the hanging load, which are connected to a central load cell. Attached to the load cell is a sensor called a strain gauge. Once you’ve hung the weight on the scale and exerted force on the load cells, the sensor detects the tension and converts the force into a readable weight measurement.
What are the benefits of using our digital crane scales?
Accuracy – Our calibrated, digital crane scales from Kern provide a far more accurate digital read-out than older, traditional scales, typically offering precision within ±0.2% of their maximum capacity (Full Scale).
High Capacity Weighing – Our range enables you to choose a crane scale that can weigh items up to 50 tonnes.
Safety – A crane scale allows you to weigh heavy items without putting your staff in harm’s way. Most of our scales can be operated and read from 20 meters away with the radio remote control, which also eliminates the tripping hazard inherent in running wires.
Space-saving within your facility – Bench and pallet truck scales can take up a lot of floor space, unlike a crane scale which can be pretty much stored anywhere without being a hazard to other warehouse traffic, such as forklift trucks and employees. This makes them perfect for industrial job sites with limited storage space.
Time-Saving – It’s nearly always easier to take the crane scale to the item rather than the item to a platform scale, saving both time and money. Digital crane scales also speed up the weighing process, offering improved efficiency through instant readings and reducing the time required for manual measurements.
Weigh Awkwardly Shaped Items – Not all items requiring weighing will sit perfectly on a set of platform scales. So, being able to suspend them and get an accurate reading helps solve this unique logistical challenge.
How durable are crane scales?
Providing they are treated respectfully, our heavy duty crane scales are durable and long-lasting. They are often made from resilient materials such as steel or aluminium, while the robust design and the bright LED display enabling you to use our crane scales in unfavourable ambient conditions.
The scales often have a IP67 rating enabling them to be used in various environments, withstanding arduous conditions docks and building sites.
Are crane scales accurate?
The accuracy of your crane weighing scales will vary depending on the model and manufacturer, but regular maintenance and calibration will ensure your measurements are reliable and on-point. Factors such as environmental conditions and load cell quality can also influence accuracy.
High-quality, electronic crane scales are designed to be very accurate, offering precision readouts and data to within a few grams. However, it’s still important to choose a scale that meets industry standards and your accuracy specifications.
