Who uses the CW 10000 and for what
The Bernardo CW 10000 is an electronic crane scale designed for weighing suspended loads up to 10,000 kg with an accuracy of 5 kg (approximately 0.05% of full scale). The typical application is in-line suspension with hoists, jib cranes, winches: the instrument is placed between the lifting system and the load to read the actual lifted weight in real time. For heavy industrial weighing: coils, industrial motors, heavy crates, containers and materials in loading/unloading sites. The large-digit LED display allows weight reading even from a distance during loading operations, a crucial feature for applications in construction sites or warehouses with reduced visibility. The typical battery life is 50-70 hours of actual use. In Krollit's customers' workshops, the CW 10000 is chosen by mechanical workshops for checking the weight of lifted parts, logistics warehouses for weighing suspended packages, carpentry shops for verifying structural weight, and construction sites for controlling loads during crane handling.
Its place in the Bernardo range
The Bernardo CW crane scale range is organized into 7 models, ordered by capacity and accuracy: CW 500 (500 kg, ±0.2 kg), CW 1000 (1,000 kg, ±0.5 kg), CW 2000 (2,000 kg, ±1 kg), CW 3000 (3,000 kg, ±1 kg), CW 5000 (5,000 kg, ±2 kg), CW 10000 (10,000 kg, ±5 kg), CW 15000 (15,000 kg, ±5 kg). The absolute accuracy decreases with increasing capacity, but the percentage accuracy remains constant (approximately 0.03-0.05% of full scale).
The CW 10000 model is in the heavy industrial range. For shipyards, large logistics warehouses, heavy industry with regular loads up to 8000 kg. The accuracy of ±5 kg (0.05% of full scale) is consistent with the level of precision required in heavy industrial applications.
Difference from the Bernardo ID series: CW are electronic dynamometers FOR WEIGHING; ID are mechanical hooks FOR LIFTING (without weight measurement). For mixed lifting + weighing applications, use a CW; for lifting only, IDs are significantly cheaper.
Krollit logistics and support
Bernardo shipping in 5-9 business days (7 days to the South). With a weight of approx. 50 kg, it is shipped in a single protective package and easily handled by one person. Chains, ropes, slings, complementary accessories, and original Bernardo spare parts are available from stock with shipping in 3-5 business days. EN 1677 compliance documentation (for ID hooks) or instrument calibration documentation (for CW dynamometers) included in the package. Customer support available in Italian.

| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Suitable |
Professional tool; for hobby use, it is oversized unless specific applications involve lifting heavy loads. |
| Mechanical workshop with parts weight control |
Recommended |
Real-time weighing during lifting to verify the actual weight of parts. ±5 kg accuracy is suitable for standard workshop loads. |
| Logistics warehouse with hoists/cranes |
Recommended |
For weighing suspended packages before loading/unloading. LED display visible from a distance, 50-70 hours of actual use battery life. |
Not suitable for: applications with loads exceeding 10,000 kg (risk of instrument damage); applications requiring accuracy greater than 5 kg (consider smaller capacity models of the same CW series); environments with continuous vibrations (digital reading may fluctuate; the instrument is designed for static weighing); environments with extreme temperatures outside the typical -10/+40°C range of industrial electronic instruments; applications requiring legal metrological certification (initial factory calibration, but not legal certification for commercial transactions by weight).

Frequently asked questions
What is the difference between the CW 10000 and a bench scale?
A crane scale weighs suspended loads (suspended from hoists, cranes, winches); a bench scale weighs loads placed on it. They are instruments for completely different applications: the crane scale is essential where the load cannot be placed (large packages, motors, suspended materials during handling).
The crane scale is placed between the lifting system and the load: the upper hook attaches to the hoist, the lower hook to the load. The internal load cell measures the tensile force and converts it into weight displayed on the LED display. For static applications on a balance, a bench/floor scale is the correct choice.
Is the instrument certified for commercial use (transactions by weight)?
No, the CW 10000 is an industrial instrument factory-calibrated but NOT metrologically certified for commercial use (purchase/sale transactions by weight). For commercial use, MID (Measuring Instruments Directive) certification issued by an accredited body is required.
For internal industrial applications (parts weight control, load verification, internal logistics weighing), factory calibration is sufficient. For commercial applications (selling materials by weight, invoicing based on weight), MID certification with a green 'M' label and official metrological stamp is mandatory: contacts are available from certifying bodies such as INRIM or equivalents.
How long does the battery last in daily use?
Typical battery life is 50-70 hours of continuous actual use. In daily craft use (10-30 minutes per day), the battery lasts 2-4 weeks before requiring recharging.
The integrated rechargeable batteries can be replaced by an authorized Bernardo service center. For intensive continuous use, a mains charger is recommended to be always available in the workshop, or to keep the instrument always charging when not in use. The auto-shutdown mode after inactivity significantly extends battery life.
Is the ±5 kg (0.05% of full scale) accuracy really significant?
For standard industrial applications, yes. At a maximum load of 10,000 kg, the relative error is approximately 0.05%. For typical working loads (50-80% of full scale), the relative error is slightly higher but remains below 0.1%.
For industrial parts weight control (motors, mechanical components, crates), the ±5 kg accuracy is correctly sized. For applications requiring higher absolute accuracy (e.g., weighing jewelry, high-value unit materials), laboratory dynamometers or precision scales, not industrial instruments, are recommended.
How does the periodic calibration procedure work?
For standard industrial use, annual periodic verification with certified standard weights is recommended. The instrument allows correction of the calibration factor through a procedure indicated in the manual.
Periodic verification can be done in the workshop with standard weights of adequate capacity (e.g., 100 kg standard weight for CW 500). For formal annual certification, contact ACCREDIA accredited calibration centers or equivalents. For internal industrial control use, initial factory calibration is sufficient for most application cycles.
