When packaged products become heavier, traditional checkweighing systems can struggle with stability, conveyor loading, product positioning and continuous operation.
For products such as large bags, cartons, barrels and other heavy packaged goods, manufacturers need more than a standard online checkweigher. The weighing platform, conveyor structure, load cell and product transfer system all need to be designed for heavier loads.
Fanchi-tech Heavy Duty Checkweigher is designed for continuous inline weighing of large packaged products, with models covering product weights from 0.1 kg up to 60 kg. The system can weigh products without stopping the production line and can be integrated with upstream and downstream conveyors for automatic weight inspection and rejection.

A 1 kg packaged product and a 25 kg or 50 kg product place completely different mechanical demands on a weighing system.
Heavy products can create greater impact during transfer and may reduce weighing stability if the conveyor structure is not properly designed. Manual weighing also becomes increasingly inefficient as package weight and production volume increase.
A heavy-duty checkweighing system allows manufacturers to move from manual sampling to continuous inline weight inspection, helping production teams identify underweight and overweight packages while maintaining production flow.
Typical applications include:
The exact machine configuration should be selected according to product weight, package dimensions, conveyor speed and production environment.
The Fanchi-tech heavy-duty series is designed for continuous production environments where large and heavy packages must be weighed accurately without interrupting the conveyor flow.
The current product specification includes three main configurations:
| Model | Weighing Range | Accuracy | Speed | Weighing Platform |
|---|---|---|---|---|
| FA-CW500 | 0.1–25 kg | ±10 g | Up to 40 pcs/min | 500 × 600/800 mm |
| FA-CW600 | 0.1–50 kg | ±25 g | Up to 35 pcs/min | 600 × 1280 mm |
| FA-CW700 | 0.1–60 kg | ±25 g | Up to 35 pcs/min | 700 × 1280 mm |
All three models use 1 g scale intervals, stainless steel 304 construction and HBM high-accuracy load cells. The system can also be configured with different conveyor heights and customized conveying dimensions according to the production line.
The FA-CW series extends dynamic weighing into applications where conventional checkweighers may not be suitable.
With models available for packages up to 25 kg, 50 kg and 60 kg, the system can be matched to different heavy-product packaging applications.
This makes it suitable for manufacturers handling large bags, cartons, barrels and other heavy end-of-line products.
Heavy products require a stable and reliable weighing platform.
The Fanchi-tech system uses an HBM high-accuracy load cell combined with high-speed digital filtering and dynamic weight tracking technology to improve weighing stability during continuous production.
This helps the system distinguish the actual product weight from temporary vibration or conveyor movement.
The machine uses 304 stainless steel construction, making it suitable for demanding industrial production environments.
The conveyor and weighing structure are designed to provide the mechanical stability required for heavy packages while allowing the system to be integrated into existing production lines.
The purpose of a dynamic checkweigher is not simply to weigh a product.
The real value is to weigh, evaluate and sort products continuously while production is running.
The product passes through the weighing section, the load cell captures the dynamic weight, the control system evaluates the result against the preset target range, and the configured rejection system can remove products outside the acceptable weight range.
This creates an automated inspection process instead of relying on manual weighing.
The installation shown in the project photos demonstrates an important advantage of heavy-duty checkweighing: the machine can be integrated with roller conveyor systems before and after the weighing section.
This type of layout is especially useful for larger cartons, bags, cases and industrial packages where smooth product transfer is critical.
For OEM production lines, Fanchi-tech can customize conveyor dimensions, line height, weighing range and rejection configuration according to the customer’s product and layout requirements.
The photos below show the Fanchi-tech heavy-duty checkweighing equipment during installation and commissioning.

The equipment is positioned directly within the production conveyor system, allowing heavy packages to enter the weighing section, pass through dynamic weight inspection and continue to the next production stage.
This type of configuration can help manufacturers reduce manual weighing operations and create a more consistent end-of-line quality-control process.
A typical Fanchi-tech heavy-duty checkweighing process consists of four stages:
The packaged product enters the checkweigher from the upstream conveyor.
Photoelectric sensors detect product position and timing before the weighing process.
The package passes over the weighing conveyor while the high-precision load cell measures the product weight.
The control system uses digital filtering and dynamic weight tracking to calculate a stable weight value.
The measured value is compared with the preset weight limits.
Products that meet the specification continue through the production line, while out-of-tolerance products can be automatically rejected using the configured reject mechanism.
The correct application depends on package weight, size and production speed.
Common applications include:
Food Processing
Industrial Packaging
Logistics & Distribution
For products with particularly irregular shapes, large dimensions or high impact during transfer, the conveyor and weighing platform should be customized around the actual product.
Manual weighing can become a bottleneck when production volume increases.
A heavy-duty inline checkweigher provides several operational advantages:
| Manual Weighing | Inline Heavy Duty Checkweighing |
|---|---|
| Operator-dependent | Automatic |
| Sampling-based | Continuous inspection |
| Manual records | Digital data retrieval |
| Requires product handling | Inline conveyor operation |
| Difficult at high throughput | Designed for continuous production |
| Higher labor involvement | Reduced manual weighing |
The Fanchi-tech system supports USB data retrieval and optional Ethernet connectivity, while the controller can store up to 100 product programs.
Before requesting a quotation, buyers should prepare the following information:
1. Product weight
For example: 10 kg, 25 kg, 40 kg or 50 kg.
2. Product dimensions
Length × width × height of the package.
3. Production speed
Packages per minute or packages per hour.
4. Conveyor height
The existing production line height determines the machine’s support and conveyor configuration.
5. Package type
Bag, carton, box, barrel, tray, case or other format.
6. Reject method
The required rejection method depends on package size, weight and production speed.
7. Production environment
Food processing, frozen food, industrial manufacturing, warehouse/logistics or another environment.
Providing these details allows the supplier to recommend an appropriate weighing platform and conveyor configuration instead of simply selecting a machine based on maximum capacity.
