Who uses the CW 15000 and for what
The Bernardo CW 15000 is an electronic hook dynamometer designed for weighing suspended loads up to 15,000 kg with an accuracy of 5 kg (approximately 0.03% 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 construction site or warehouse applications with reduced visibility. The typical battery life is 50-70 hours of actual use. In Krollit customers' laboratories, the CW 15000 is chosen by mechanical workshops for checking the weight of lifted parts, logistics warehouses for weighing suspended packages, carpentry shops for verifying the weight of structures, and construction sites for controlling loads during crane handling.
Its place in the Bernardo range
The Bernardo CW hook dynamometer 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). Absolute accuracy decreases with increasing capacity, but percentage accuracy remains constant (approximately 0.03-0.05% of full scale).
CW 15000 model: heavy industrial range. For shipyards, large logistics warehouses, heavy industry with regular loads up to 12,000 kg. The accuracy of ±5 kg (0.03% of full scale) is consistent with the level of precision required in heavy industrial applications.
Difference with the Bernardo ID series: the CW are electronic dynamometers FOR WEIGHING; the ID are mechanical hooks FOR LIFTING (without weight measurement). For mixed lifting + weighing applications, use a CW; for lifting only, the ID are significantly more economical.
Krollit logistics and support
Bernardo shipping in 5-9 working days (7 days to the South). With a weight of approx. 58 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 available from stock with 3-5 working day shipping. EN 1677 conformity documentation (for ID hooks) or instrument calibration documentation (for CW dynamometers) included in the package. Customer support available in Italian.
Who is the CW 15000 for?
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Adequate |
Professional tool; for hobby use, it is oversized unless specific applications involve lifting heavy loads. |
| Mechanical workshop with part weight control |
Recommended |
Real-time weighing during lifting to verify the actual weight of parts. Accuracy ±5 kg 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 autonomy. |
Not suitable for: applications with loads exceeding 15,000 kg (risk of instrument damage); applications requiring accuracy greater than 5 kg (consider models with lower capacity from 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 15000 and a bench scale?
A hook dynamometer weighs suspended loads (suspended from hoists, cranes, winches); a bench scale weighs loads placed on it. They are instruments for completely different applications: the dynamometer is essential where the load cannot be placed on a surface (large packages, motors, materials suspended during handling).
The hook dynamometer 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 pulling force and converts it into weight displayed on the LED display. For static applications on a weighbridge, a bench/floor scale is the correct choice.
Is the instrument certified for commercial use (transactions by weight)?
No, the CW 15000 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 (part weight control, load verification, weighing for internal logistics), factory calibration is sufficient. For commercial applications (sale of 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 equivalent.
How long does the battery last in daily use?
Typical battery life is 50-70 hours of actual continuous use. In daily artisan 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 should always be available in the workshop, or the instrument should be kept constantly charging when not in use. The auto-off mode after inactivity significantly extends battery life.
Is the ±5 kg accuracy (0.03% of full scale) truly significant?
For standard industrial applications, yes. For a maximum load of 15,000 kg, the relative error is approximately 0.03%. For typical working loads (50-80% of full scale), the relative error is slightly higher but remains below 0.1%.
For industrial part weight control (motors, mechanical components, crates), the ±5 kg accuracy is appropriately sized. For applications requiring higher absolute accuracy (e.g., weighing jewelry, high unit value materials), laboratory dynamometers or precision balances are recommended, not industrial instruments.
How does the periodic calibration procedure work?
For standard industrial use, annual periodic verification with certified test weights is recommended. The instrument allows correction of the calibration factor using the procedure indicated in the manual.
Periodic verification can be carried out in the workshop with appropriate capacity test weights (e.g., 100 kg test weight for CW 500). For formal annual certification, contact accredited ACCREDIA calibration centers or equivalent. For internal industrial control use, initial factory calibration is sufficient for most application cycles.
