• Accurate measurements: Crane scales are known for their incredible performance even in versatile warehouse conditions by providing weighing accuracy of 0.1% with a capacity of up to 50 tons.

1. Streamline operations: Crane scale is perfect for operations that require weighing without transporting the loads to a weigh station. Adopting these scales can increase your productivity and weighing efficiency.

1. Safer workspace: Crane scales eliminate the goods transportation to a weighing area and decrease the forklift traffic that decreases the chances of accidents, injuries, and losses.

What are the Safety Considerations of a Crane Scale?

The primary use of crane scales is to handle and weigh very heavy materials efficiently.

A workstation accident can have devastating consequences, and preventing them is important to enhance business productivity.

When choosing an industrial scale, it’s a good decision to choose one that offers a maximum load capacity of at least 5-10% higher than recommended.

Anything that exceeds two-third of the maximum load capacity of a scale must not be weighted.

The reason why you need a margin of a minimum of 5-10% of the maximum load limit is that crane scales are often used to weigh dynamic loads.

If a load that’s right at the crane scale’s limit moves, it can cause the load cells to overload and can either output in-accurate readings or can malfunction.

How to Measure Range and Resolution of a Crane Scale?

A crane scale is an ideal piece of equipment for industrial, commercial, sports, agriculture, and leisure.

These industrial scales belong to the group of mechanical balances that doesn’t require an electronic component or a power supply for measurements and display.

A Crane scale measures weight with the help of the relationship between force and spring travel.

For a certain range of values, the distance covered during stretching/compression is proportional to the applied force.

Due to their ergonomic design, the advanced load cells of these scales are extremely robust against environmental influences.

The measuring range and the resolution of a crane scale can be varied via the following:

• The material of the spiral spring
• The thickness of the spiral spring
• The geometry of the spiral spring

The measuring ranges of crane scales range from a few grams to several kilograms.

On the other hand, the resolution of the crane scale is commonly one-hundredth of the measuring range because of its readability.

Figure 17.1 – Measuring Range and Resolution of a Crane Scale

What is Zero Point and Tare in a Crane Scale?

Zero-point is a crane scale primary function that can return the scale to zero when nothing is placed on it to start new weighing processes or finish one.

On the other hand, tare can be used to remove the unwanted weight of an item from the scale, such as a container.

Tare helps us know the actual weight of the product. In the latest crane scale models, the zero points can be easily adjusted.

What is the Accuracy of a Crane Scale?

The measuring accuracy of a standard crane scale is 0.2% and thus is often even better than the resolution.

At CUBLiFT, we manufacture high-quality ergonomically designed crane scales that can even offer 0.1% weighing accuracy.

With the advanced load cells technology, we implement in our crane scales, you can get ultimate precision in your weighing processes.

Crane scales are easy to calibrate. Calibration of crane scales means loading test weights and comparing the result on display with the mass of that weight.

Figure 19.1 – Maintaining Precision with a Crane Scale

How to Measure Tensile and Compression Force with a Crane Scale?

Crane scales are put under tension for weighing, and the use of advanced weighing technology can help manufacturers achieve precision.

Measuring the mass is possible with weight force caused by gravity, and that’s the mechanism behind crane scales.

Attaching a weight with a crane scale, lifting it, and measuring tensile forces can give us the weight measurements.

Moreover, measuring compressive forces is also possible with crane scales.

These industrial scales are already equipped with hardware to measure both compression and tension forces.

The scale is compressed by the pressure and calculated. When measuring, it is important to place the scales at right angles to achieve accuracy.

What Things to Consider Before Purchasing a Crane Scale?

What benefits crane scales offer are fairly clear. Before going for the crane scale model that is ideal for your business, you need to consider the following:

The criteria for selecting a crane scale:

• Weighing range: It’s probably the most important because it can determine immediately whether a particular crane scale is suitable for your applications or not.

• Readability or resolution: It mostly depends on the weighing range of a crane scale. With the right manufacturer, you can get a resolution of 0.1 kg per 1500kg.

• Calibration or verification: A verified crane scale is pre-calibrated and is difficult to change later. On the other hand, calibration crane scales enable you to calibrate your scale whenever required.

• Follow-up cost: After purchasing one, its maintenance and calibration are the highest costs which are recommended annually. However, these costs completely depend on the accuracy and the weighing range of the crane scale.

• Remote display and data transmission: A crane scale doesn’t require more than an integrated display. However, the latest models feature Bluetooth or ports to enable connectivity with other hardware devices.

Additionally, precision and accuracy are the most important factors to consider.

However, there are some secondary factors to consider that can be extremely helpful, including:

1. Industry and applications: Making sure that a particular crane scale model can work efficiently in your particular work environment by fulfilling your application needs can determine its productiveness.

1. Versatility: Crane scales that allow you to change measurement units are more versatile and easier to integrate into your work environments.

• Easy to use: Some of the advanced crane scale models can be complex to use. Similar models can higher the risk of errors and accidents. Always go for a crane scale that your staff can understand and use efficiently.
