1000 kg Crane Scales
Electronic crane scales are available in a wide range of sizes and are capable of weighing different loads. However, sometimes smaller is better. Sometimes, a 1000 kg is all the weighing capacity that is required.
There are advantages to sizing a scale to the maximum load. Obviously, the scale should NOT be expected to support more than the maximum load. So why not buy the crane weigher with the largest maximum load? This has to do with digitization error and the accuracy that can be expected from a system.
Crane Scales by Eilon Engineering
Eilon Engineering has been fitting crane scales to a variety of requirements for over 45 years. Their highly customizable product line ensures that customers can match the maximum load of their work to the proper crane scale, ensuring high accuracy and repeatability. The Ron line of crane scales are available with many maximum capacities, and with options for wired and wireless interfaces. Their compact size means industry-leading minimal headroom loss.
Crane scales can be connected in a variety of ways. Wired connections and wireless connections to a remote indicator are available. For downloading data, RS232 ports are standard. Furthermore there is an optional add-on for viewing data over Bluetooth.
The error on any crane scale is commonly based on its maximum load. Digitization error is inherent in any electronic crane scale, and that the error will be expressed as a percent of the maximum load. Therefore, the closer the lifted load is to the maximum load rating of the scale, the more accurate the crane scale. For example and Eilon Engineering scale with a 1000 kg capacity would have an error rate of +/- 1 kg, while a similar scale with 10,000 kg capacity would have an error rate for +/- 10 kg. (+/- 0.1% of full scale)
No, they suffer from a similar source of error, though it is not commonly called “digitization error.” When the operator looks at the needle or looks at the revolving mechanical numbers, they will have to make a judgment as to whether the needle has landed on a tick mark.. A high quality digital scale’s digitization error is much smaller than this operator error.
I work at a growing facility, and the load requirements may change over time. Should I buy a “one size fits all” type scale?
No, due to the digitization error described above. Eilon Engineering scales are easy to install and remove as needed, meaning it will be better to have a range of scales available depending on the load size.
The Eilon Engineering Advantage
Eilon Engineering has been a leader among overhead crane scale manufacturers, designing and building crane weighing systems for over 45 years. They have serviced many fields, including aerospace, manufacturing, metal casting and material handling, docks, fishing vessels and many others. Their scales are widely used in heavy industry, as they are known for their accuracy and ruggedness all in a compact package.
All Eilon Engineering crane scales are built with accuracy in mind. Increased accuracy means increased safety assurance by limiting the chances of an overload condition. Increased accuracy also means more consistent loading of product and, for example, validation of the amount of raw materials unloaded. By maintaining high accuracy operations which require multiple crane loads can be tracked more effectively.
Because loose material, such as quarried gravel, or natural products, such as fish caught, can vary in shape and size, the volume and mass of each load may vary. With an accurate crane scale, the mass can be tracked, even across multiple crane loads.
The 1000 kg crane scales produced by Eilon Engineering each have an error of only 1 kg. This small error is much smaller than could be achieved with an analog scale or many competing digital scales.
Eilon Engineering scales are also built to withstand the rigorous demands of industrial use. Every scale is built with aerospace steel for longevity and fatigue resistance. They have internal shock absorbers to reduce vibration and sudden shock to the electronics. Scales are tested to a 200% load and meet ASME BTH-1-2017, ASME B30.26, and IEC 61508 standards for fatigue. Shackles are mounted at a 90 degree offset for increased strength and for decreased bending moments during loading and unloading.
