Crane scales are a type of hanging scale used in a wide range of commercial and industrial operations. Here’s everything you need to know about them, including common applications, purchasing advice and safety considerations.

What’s a crane scale? Crane scales, and hanging scales in general perform two important functions: they provide a measurement of an item’s weight and they ensure operators don’t overload cranes or hoists. Overloading presents a safety hazard as well as considerable losses due to broken equipment and machinery. They’re ideal for measuring bulky, oversized loads that can’t be easily weighed using platform scales. They’re typically used for things like weighing freight before it’s transported on planes, trains and ships and determining whether a load is too heavy to be lifted by a crane or other piece of equipment. Crane scales are attached to the crane or hoist’s hook. The digital readout indicates the weight of the load as well as the amount of force being placed on the crane, allowing you to determine whether the crane can transport it. Crane scales vary widely in price, depending on features and capacity. Key features Crane scales range from high-capacity steel units designed for heavy-duty use to precise and lightweight aluminum small-capacity units. Modern crane scales are built to be used in dynamic work environments, meaning they’re not influenced by swaying and they have built-in stability adjustment capabilities to accommodate a range of environmental conditions. Properly calibrated, crane scales offer an efficient and flexible way to weigh materials, as most of them allow operators to switch between different measurement units. In addition, they’re accurate within 0.1 to 0.2 per cent, even when weighing the heaviest of objects. Finally, their large LED screen allows operators to read results from several feet away, even in low visibility conditions. Why you may need crane scales Crane scales have many advantages over traditional weighing solutions. Here are some reasons you might want to consider purchasing one.

• You need to save floor space. Space is usually at a premium and your facilities may not be able to accommodate a weighing area or floor scale. A crane scale can be taken to the item you need to weigh, meaning you don’t need to sacrifice precious space.

• You need to weigh awkwardly shaped items. Some items are unwieldy and awkward to balance. A crane system will allow you to weigh these items precisely and accurately.

• You need accurate measurements. If you’re loading a freighter, manufacturing an aircraft tire or using your scale to portion out goods sold by weight, then precision and accuracy are crucial. Some models can withstand industrial use while providing measurements that are accurate within 0.1 per cent with a capacity of up to 200,000 kilograms (about 220 U.S. tons).

• You want to streamline operations. Eliminating the need to move items to a specific weigh station means more hours of labour going toward increasing productivity. Cutting down on forklift traffic will allow you to keep your team focused on bringing in and processing customer orders.

• You want a safer workspace. With crane scales, you don’t need to transport goods to a weighing area with forklifts. A decrease in forklift traffic means fewer opportunities for accidents, injuries and losses. Your operations will be safer and more efficient.

8 things to consider before buying a crane scale The advantages of crane scales are fairly clear. However, here are eight key things to consider when deciding which one you should purchase.

1. The average load weight. Perhaps the most important factor to consider when choosing a crane scale is the average weight of the load you’ll be weighing. Some scales can handle loads that that weigh upwards of 100,000 kilograms while others are designed to give very precise measurements for small loads of 10 to 50 kilograms. Keep in mind that the expected maximum weight shouldn’t exceed two-thirds of the maximum permissible rated load of the scale. Otherwise, you’re putting the equipment and everyone nearby in danger.

2. Industry and applications. Make sure the model you purchase matches your specifications and application needs. You’ll need a much more durable and heavy-duty hanging scale for lifting large loads on a construction site or shipping dock than for weighing smaller loads in a store or stockroom. You should also consider whether you’ll need to be able to attach the scale to other equipment, read the display screen from far away or operate the scale remotely.

3. Manufacturing compliance. Make sure the company you’re buying from manufactures and calibrates in accordance with local regulations, especially those related to measurement values, units, accuracy and safety.

4. Ease of use. You want crane scales that are easy to use and read. Hard-to-use models could cancel out the efficiency gains of using crane scales in addition to introducing a higher risk of error and accidents.

5. Precision and accuracy. When selecting a scale, pay attention to the how sensitive, or precise, the scale is. The measurement precision you’ll need will depend on what you’re using the scale for. Similarly, accuracy may prove crucial depending on the application. It’s also important to consider that load volume is critical, as freight cargo might shift and cause catastrophic accidents if the load is unbalanced.

6. Professional installation. Higher capacity crane scales need to be professionally installed, calibrated and maintained. It’s a good idea to train your workers so they know the basics of the scale’s operation and are able to spot issues.

7. Versatility. Look for models that allow you to change measurement units. The more versatile the crane, the easier it will be to integrate the crane scale into your business operations.

8. Work environment. Finally, you should think about the type of environment in which you’ll be using the crane scale. Some models work best at certain temperatures and in dry environments while others are suitable for all weather conditions and are resistant to dust and water.

Safety considerations Crane scales are often used to handle very heavy materials. An accident can have devastating consequences. When choosing a scale, you need to make sure it won’t be used to weight anything exceeding two-thirds of its maximum load. The reason you need that wide of a margin is that crane scales are often used to weigh dynamic loads, meaning they could move during the weighing process. If a load that’s right at the crane’s limit moves, it can cause the load cells to overload. Overloading can pose a serious risk to the equipment and the safety of staff working in the area. As crane scales are integrated into lifting equipment, it’s recommended to have them inspected by a professional every three months, since a problem could mean lifting equipment malfunction. This is usually enough to spot any potential problem. Alberta’s scales experts Accurate/Western Scale Co. Ltd. offers a wide range of crane scales as well as calibrations, servicing and rentals.

Hopper scales and all other measuring equipment used in trade must be approved and inspected by a scale inspector accredited by Measurement Canada. This ensures fair business practices and is a requirement under the Weight and Measures Act. Keep reading to learn more about why inspections of hopper scales are important and what the inspection process involves.

Why are inspections needed?
In order for your hopper scale to be properly certified, it needs to pass an inspection from a certified scale inspector. This ensures, first and foremost, that businesses don’t short-sell customers. There are penalties for short-selling, even when it’s inadvertent. When this activity occurs, or when businesses otherwise fail to comply with Measurement Canada’s regulations, they can face the following consequences:

• Fines of up to $50,000
• Equipment being taken out of service until modifications or repairs are made, resulting in a loss of productivity and revenue
• Damage to the company’s reputation

How often are inspections required?

The timeframe for mandatory inspections varies between industries. For example, in grain elevators licensed by the Canadian Grain Commission, hopper scales need to be inspected yearly; in the mining industry, hopper scales need to be inspected every two years.

In certain industries, scale inspections are recommended, but not mandatory. The onus is therefore entirely on businesses to have their scales inspected and to ensure their accuracy.

Consult the Measurement Canada website for more precise information on the timeline for mandatory inspection or recommended inspection for your hopper scale.

Precisions scales have a wide range of applications. Finding the right one is a matter of understanding which features meet your needs. Here’s what you should keep in mind when selecting a digital precision scale.

Measurement units

The first thing to consider is whether you’ll need a scale that uses specialized units such as carats or grains. Determining which units you’ll need to use is a good starting point, as it’ll allow you to narrow down your selection. You should also factor in whether you’re likely to expand your scale’s applications in the long run.

Capacity

Determining the maximum weight the scale needs to handle is another way to narrow down your options. If you need to weigh bulk or large quantities — for instance, in commercial applications — you’ll need to select a scale with a higher capacity. It’s also important to consider the size of the materials you’ll be weighing, to make sure you select a scale with a large enough plate.

Accuracy and precision

Applications requiring high accuracy typically won’t need as much capacity. Weighing medical products or working in a laboratory setting will necessitate a highly accurate scale that can take exact measurements.

Some applications will also require a scale that’s highly precise. In this case, precision refers to how consistent a scale’s readout is, whereas accuracy refers to how closely the readout matches the actual weight of the object. Keep in mind that regulations apply to the accuracy of scales used for commercial applications.

Size and portability

Some scales need to be portable, especially when used for field work. However, since a host of environmental factors influence a scale’s accuracy, it’s important to make sure that portable models are recalibrated whenever they’re moved.

It’s also important to consider how the scale is powered. If you’ll need to use it in situations where you don’t have access to a power source, then selecting one with appropriate battery life is crucial.

Other features

Depending on the materials you work with and the measurements you need to perform, you may have to select a scale that can keep a record of measurements or enables recipe weighting or piece counting. Modern digital scales are versatile, but always keep in mind that there’s a trade-off between functionalities.

A lift truck scale requires a substantial investment, but it’s a smart one. Despite higher upfront costs, they have numerous advantages over traditional floor scales. Here’s why your business might benefit from one.

You have limited floor space
If you’re a new or growing company, every bit of space is valuable. Even if you can dedicate some of your available footage to a floor scale, the traffic lanes used to access it will take up a lot more space than you may be able to truly afford. Switching to a lift truck scale will free up these lanes, allowing for more efficient use of your space.

You need to increase efficiency
Many businesses need to weigh materials and integrating the weighing step into the normal workflow instead of requiring the time-consuming diversions needed with floor scales can drastically improve efficiency. A material handling scale allows for weights to be taken during normal operations, which speeds up completion times.

You want a leaner operation
Because they reduce the number of steps involved in operations and reduce resource and space usage, lift truck scales are a smart investment for companies looking to streamline their operations. Increased efficiency and lower resource use translate to higher profit margins.

You want to reduce traffic
Heavy lift truck traffic reduces efficiency, increases costs and, most importantly, can pose serious safety issues. Floor scales directly contribute to this problem by requiring drivers to make unnecessary trips.

You want to keep your employees safe
Industries that use lift trucks often work with pallets. Equipping your trucks with scales will reduce the risk of overloaded pallet racking. Overloading the racking can compromise its structural integrity, leading to extremely costly accidents and severe or fatal injuries.

Equipping lift trucks with material handling scales ensures that workers know exactly how much weight is being put on the racking. It also eliminates the need for trips to the floor scale, which are time-consuming.
