Types of big platform weighing scale

There are various kinds of big platform weighing scale. Below are a few types.

An digital platform weighing scale

The big digital platform weighing scale is one of the most popular big platform scales due to its convenience. These scales show results digitally on the scale screen. They are also known as digital crane scales because they can give precise results with just a push of a button.

Mechanical platform weighing scale

These platform scales used weight measurement through balance. A mechanical platform weighing scale contains springs and levers. Users will see the result on the moving pointer. It does not require battery power or charging, so users can use it where there is no electricity.

Large platform scale with checkweighing function

These platforms are useful in production environments. Not all large weighing scales are checkweighing, but some of them have this special feature. These platforms will compare the current item's weight with the saved preset weights. A visual warning will appear, so the operators will know if the item is overweight or underweight.

Waterproof platform weighing scale

These large platform scales can be exposed in wet or dusty conditions. These scales have waterproof covers and can also measure wet and dusty objects. The platform's body and load cells are sealed from water and dust by a scale with an IP67 rating.

Large platform scale with remote display

This weighing platform has remote display features. Such devices are used when the weighing items are placed at elevated heights. This setup allows the operator to view the weight reading at a safe distance without constantly looking up at the suspended load.

Installation and maintenance of big platform weighing scale

After selecting the right large weighing scale, users should also consider the installation process and maintenance.

A few important points to note about the scale installation are as follows:

The platform should be placed on a sturdy and level ground. The place should be free from vibrations and weigh fluctuations.
The weighing scale should be in a position where all four corners of the platform are accessible. The load cells should be easily reachable for adjusting, wiring, and calibrating purposes.
The scale's feet should be bolted to the ground to prevent any movement.

Calibrating the scale

Calibrating the digital platform scale at frequent intervals is also important during maintenance for more accurate results. Calibration is done through the correct fixed weights of an item. The scales are adjusted to read the correct value by placing these weights on the platform.

Checking functions of the scale

After a long period of use, one may find its large platform scale not making precise measurements. In this case, the operator should do a basic reset of the scale. They should also check the wiring and connections of the load cell. Sometimes a simple reset can solve the problem.

Inspecting scale components

Users should check the scale's platform; sometimes, other objects fall on it and affect its performance. Cleaning the platform helps enhance the quality of the scale. The load cells and signals will also be affected by the dust on the load cell. So users should check and clean it regularly.

In short, maintaining the weighing scale platform will ensure effective operation for many years. As stated above, proper installation and calibration help prevent many problems, increasing the platform's lifespan and enhancing its accuracy.

How to choose big platform weighing scale

Choosing the right platform scale for weighing big items of different products is challenging when there are so many options available. Hence, here are a few factors manufacturers consider when making their choice.

One of the key aspects that one needs to think about is the balance's capacity. This capacity defines the maximum and minimum weight that a scale can weigh. Depending on their requirements, industry owners will opt for a huge platform scale that targets higher capacities. For example, a large digital crane scale with a capacity of over 5 tons.

These scales are available in different sizes. Thus, the size of the platform will depend upon the product that requires the weighing process. So, if the item needs weighing is large, the industry owner should look for a digital weighing scale with a wider platform.

Large platform scales can employ different weighing methods. The common method is using load cells, which are cost-effective and give precise results. Some scales still employ mechanical balancing systems. The digital readout makes it easier to take the measurements. Scales proposing load cell technology are more accurate than those proposing balance scales.

Check the scale's materials and features. It helps the user prevent the deterioration of the scale due to exposure to humidity, high temperatures, and such. A digital scale with a platform made of stainless steel or high-grade polymers can withstand high humidity or wet conditions.

Another key factor for industry owners to consider is the possibility of integrating the system into their own. For instance, large platform scales in the production lines can be linked to the systems to collect and analyze data. The scale should be fitted with multichannel outputs and interface possibilities with the existing systems.

Finally, when investing this much into a large platform scale, it makes sense to consider after-care services from the supplier. This includes warranties, calibration, and servicing to minimize the down-time on inaccurate readings.

In summary, industry owners must consider the following factors when choosing a large platform scale:

Capacitance
Platform size
Materials and features
Weighing methods
Maintenance and warranties

Q&A

Q1. Which industries need to use large platform weighing scales?

A1. Any industry that requires weighing large and heavy products can use big platform scales. They are commonly used in warehouses to weigh loads on pallets before lifting them. They are also used in transportation and logistics to weigh incoming and outgoing shipments.

These scales are also used in manufacturing. For example, they help in measuring big parts so that the correct amount of metal, plastic, and other raw materials can be estimated. Such scales are normally used in bulk storage to measure the weight of items such as bags of chemicals for monitoring stock levels.

Q2. How accurate are large platform scales?

A2. The accuracy of large platform scales varies depending on the model and load cell technology used. High-capacity scales may offer accuracy within ±0.5% of full scale under heavy load. In contrast, lighter loads could yield variance of ±1% or more.

However, following the manufacturer's guidance regarding maintenance, calibration, and environmental placement will enhance the scale's accuracy. Also, selecting the platform scale with the correct capacity will help in obtaining accurate results.

Q3. Are big platform scales portable?

A3. Some large big platform scales are portable. These platform scales generally come with detachable legs, built-in wheels, and lighter materials like aluminum or plastic for easier movement and use when required.

However, with portability, often sacrificing stability and precision for its heavy-duty counterpart. The weighing machines that weigh big platforms are intended to be stationary in spaces like factories. So the portability feature would not be a concern for these scales.

Q4. Can large platform scales be used outdoors?

A4. Large platform scales can be used outdoors, but choosing one that is specifically designed for outdoor use is essential. These scales will be constructed from waterproof and weather-resistant materials such as stainless steel.

In addition, the scales will likely carry higher IP ratings than their indoor counterparts to protect against water, dust, and debris.

Q5. How to protect the large platform scale from harsh environment conditions?

A5. The large platform scale should be covered with waterproof and dustproof materials. The load cells and other internal parts of the product are made of stainless steel or high-grade polymer.

The machine's platform itself should also be constructed using premium materials and the latest techniques to prevent sliding and ensure appropriate footing for the object undergoing measurement. Selecting a machine with a high IP rating ensures the machine can effectively take on humidity and dust.
