Who uses the ID 6400 and for what
The Bernardo ID 6400 is a forged steel mechanical lifting hook designed for capacities up to 6,400 kg. Key design feature: the integrated safety device (spring-loaded closing latch) prevents accidental release of the sling during lifting. For operator safety in lifting operations, the safety device is legally mandatory (European standard EN 1677 on lifting hooks). 6,400 kg capacity designed for heavy industrial lifting: complete machinery, containers, heavy metal structures. The Ø 27.9 mm hole allows connection to chains, wire ropes, textile slings, or standard lifting straps. The hook opening C 48 mm defines the dimensions of the compatible sling eyelet. In Krollit customers' workshops, the ID 6400 hook is chosen by mechanical workshops, metal carpentry shops, construction sites, logistics warehouses, and all contexts where lifting operations require certified hooks according to European standard EN 1677.
Its place in the Bernardo range
The Bernardo ID range of lifting hooks is organized into 6 models by capacity: ID 250 (250 kg), ID 500 (500 kg), ID 1000 (1,000 kg), ID 2000 (2,000 kg), ID 3200 (3,200 kg), ID 6400 (6,400 kg). All models are made of high-strength forged steel with an integrated safety device (automatic spring-loaded closing latch) conforming to European standard EN 1677.
ID 6400 is the top of the range with a capacity of 6,400 kg. Hole Ø 27.9 mm (vs 21.8 of the 2000-3200 range), dimensions A 274 × B 114.8 × C 48 mm. For continuous heavy industrial applications or even higher capacities, consider special lifting hooks or multi-hook systems.
Difference with the Bernardo CW series: ID hooks are pure lifting hooks (without weight measurement); CW hooks are electronic dynamometers with a hook (with integrated weighing system). For lifting-only applications, ID hooks are economical and robust; for applications where weighing the suspended load is also required, choose CW.
Krollit Logistics and Support
Bernardo shipping in 5-9 working days (7 days to the South). Weighing approximately 1 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 3-5 working days 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 the ID 6400 is for
| Profile |
Compatibility |
Reason |
| Hobbyist with occasional lifting |
Adequate |
For occasional lifting of engines, equipment, materials in a home workshop. Integrated safety device, EN 1677 certification. |
| Mechanical workshop with regular lifting |
Recommended |
For lifting engines, mechanical components, equipment in the workshop. High-strength forged steel, safety device for daily operations. |
| Carpentry / construction site |
Recommended |
For lifting metal structures, building materials, construction site equipment. EN 1677 conformity mandatory for professional use on site. |
Not suitable for: applications with loads exceeding 6,400 kg (risk of hook breakage and serious injury); applications with dynamic or impulsive loads exceeding the certified static capacity (respect the safety factors declared by the manufacturer); applications requiring load weighing (the CW dynamometer series is the correct choice); corrosive environments without adequate protection (forged steel is galvanized but not resistant to aggressive solvents or marine atmospheres); use without the safety device closed (the closing latch MUST always be intact: if damaged, replace the hook immediately).

Frequently Asked Questions
What does 'integrated safety device' mean on a lifting hook?
It is a spring-loaded closing latch that automatically closes the hook opening once the sling is inserted: it prevents accidental release of the sling during lifting. It is legally mandatory in lifting operations according to European standard EN 1677.
Without a safety device, during a lift, the sling could accidentally disengage due to oscillations, impacts, or rotation of the load, with the risk of the load falling and serious injury. The safety device is a crucial component of the hook: if the closing latch is damaged or does not close correctly, the hook MUST NOT be used and must be replaced immediately.
Is the 6,400 kg capacity really safe?
Yes, with a standard safety factor. The 6,400 kg capacity is the certified Working Load Limit (WLL): the hook is designed to withstand approximately 4 times this load before static failure. The minimum safety factor is 4:1 according to EN 1677.
Important: the WLL refers to static vertical loads. For dynamic loads (fast lifts, impacts, oscillations), the effective capacity is reduced. For angular slings (2 or 4-leg chains forming an angle with the vertical), the effective capacity of each hook is significantly reduced: at a 60° opening, the effective capacity is 50% of the nominal. Consult EN 818-2 tables for correct sizing.
How often should the hook be inspected?
For daily professional use: visual inspection before each use, thorough inspection every 6-12 months by qualified personnel. For occasional use: annual thorough inspection. Italian legislation requires recording of periodic inspections.
What to check during inspections: deformation of the hook body (elongation of the opening), integrity of the safety device (latch closes correctly), absence of cracks or excessive wear, legibility of the capacity marking. If even one of these conditions is not met, the hook must be replaced. EN 1677-1 provides detailed evaluation criteria.
Can I use the hook with chains or only with textile slings?
With both. The Ø 27.9 mm hole allows connection to lifting chains (check compatible link diameter), wire ropes (with thimble), textile slings with eyelets, lifting straps. Compatibility depends on the dimensions of the sling eyelet.
For lifting chains, the chain's capacity MUST be equal to or greater than the hook's capacity: using a chain with a lower capacity than the hook entails the risk of chain breakage. Textile slings (straps, slings) typically have higher safety factors than chains (5:1 or 7:1). For continuous heavy industrial applications, chains are preferable for longer durability.
Can the safety closing latch be replaced?
Yes, it is a replaceable component. In case of damage to the latch or the return spring, the original Bernardo spare part is available from stock. Replacement is a simple operation (5-10 minutes) that does not require specialized skills.
The safety device is a consumable component subject to wear: in daily operations, the spring may lose tension, the latch may deform due to accidental impacts. For intensive use, it is recommended to keep a stock of spare parts in the warehouse. Daily visual inspection to ensure the closing latch functions correctly before each use.
