How to Use Hanging Scales and Crane Scales
Warehouses and factories can be high-pressure environments, where employees often must perform tasks quickly and correctly in spite of numerous distractions. If a worker is unable to concentrate on the task at hand, efficiency can decrease and accuracy can go by the wayside. In the worst-case scenario, safety can be compromised, which can be dangerous for the employee and expensive for the employer. That’s why it is essential that the tools and equipment used in your workplace are safe, easy to operate, and help streamline the production process.
This introduction to industrial hanging scales and crane scales provides answers to common questions such as “What are hanging scales? How are they used? What makes them different from other industrial scale varieties?”
What are hanging scales?
Hanging scales are used to describe a wide variety of digital and mechanical scales that are used to weigh objects by hand or suspended from a fixed position and include crane scales, spring scales and
What are hanging scales used for?
Hanging scales are adaptable weighing machines that can be used for a variety of different applications. For example, farmers can use hanging scales to measure feed bags, helping them ensure that each bag meets a predetermined weight before feeding to animals. This helps the farmer monitor feed quantities, especially important for animals that must be kept on a regulated eating regime. This allows farmers or vets to monitor the animal’s weight and to track any unexpected fluctuations.
For commercial applications, hanging scales can be used for weighing mail bags in post offices before distribution, allowing postal depot workers to pack mail appropriately. By marking a maximum weight, workers can ensure that each mail bag is not too heavy to lift. Alternatively, they can be used to check the weight of baggage at airports, to make certain suitcases are under the required weight limit designated by airlines.
Fishing enthusiasts use certain varieties of hanging scale to suspend-weigh caught fish by attaching the below balance hook under the fish's gill plate. Whilst, fishing competitions may use weight as a placing criteria and therefore require regulation approved weighing scales (see our article on choosing a fishing scale for more information).
Why would I need an industrial weighing scale?
Weighing is an essential part of many production and distribution processes, whether it’s used to weigh pallets of products for distribution to retail supermarkets; for counting the number of items based on weight measurement, or checkweighing products to ensure they align with a specified product weight.
Using the correct industrial weighing scale has the potential to increase productivity and ensure employee safety when working in factory or warehouse environments. However, increased competition within the weighing sector means that choosing the best industrial scale for your needs can prove challenging, with greater variety and larger weighing capacities being released each year.
What is the difference between hanging scales and crane scales?
The main difference between a hanging scale and a crane scale is related to capacity and cost. Hanging scales are used for lighter weighing tasks and tend to be less expensive as a result. Crane scales are better-equipped to deal with large industrial weighing applications and can be more costly.
How to use a hanging scale?
1) Ensure that the object you are weighing has a secure handle or attachment for lifting.
2) Place the object on a level surface.
3) Using the suspension hook on the scale, hook this around the object's handle.
4) Lift the object with the hand grip at the top of the hanging scale.
5) Check the LED screen on the scale for the object's weight.
How much weight can a hanging scale measure?
Typical hanging scales tend to have lesser weight capacities, and generally can accommodate loads of up to 50kg, whilst other suspension scales such as crane scales can weigh loads of 10,000kg or more. When using a crane scale it is important to take note of the SWL (Safe Working Load) weight limit on the scale's label, this will indicate the maximum weight capacity a crane scale can lift before being deemed unsafe.
What is SWL?
SWL (Safe Working Load) is a rating given to a crane or similar lifting type mechanism to indicate how much weight the machine can support without risk of breaking. SWL is calculated by the manufacturer by dividing the MBS (Minimum Breaking Strength) by a self-defined risk factor, which is often worked out as a ratio ranging from 10:1 to 4:1 of the machines weight.
Should I use a hanging scale or crane scale?
This ultimately depends on your weighing requirements, available space and your budget.
Large industrial warehouses, shipping operations, or loading docks are more likely to require heavy-duty equipment such as crane scales, as they will be weighing large containers, pallets and crates on a regular basis.
Hanging scales are more convenient than crane scales and tend to have have lower weighing capacities. They are better suited for personal use for weighing tote bags of produce or where manual weighing is preferred.
Take into consideration what you’ll be weighing and other requirements. This will help you determine whether your business needs to weigh items that exceed the weight capacity of hanging scales. If so, crane scales are the best choice.
