K63kæder

K63kæder is a Danish term for a class of heavy-duty steel chains used for lifting, securing, and conveying loads. The designation “K63” identifies a specific size and strength category within the chain family and is used by manufacturers and in Danish industry to differentiate from lighter or other-grade chains. These chains are designed to provide reliable performance under high loads in environments such as construction, forestry, and industrial settings.

Construction and design: K63kæder are typically made from carbon or alloy steel and consist of interlinked plates connected by pins. Joints may be welded or riveted depending on the design and application. The strength and working load limit (WLL) are determined by material quality, heat treatment, chain diameter, pin diameter, and overall link geometry. Chains can be supplied in several sizes within the K63 designation, with markings indicating WLL, length, grade, and inspection date.

Standards and rating: In many markets, chains like K63kæder are manufactured to comply with EN 818 (lifting chains) or equivalent national standards for safe operation. Users should refer to manufacturer specifications for the precise WLL, safe working temperature, and fatigue life.

Applications: They are used to lift heavy loads with chain slings, secure loads on transport, tie-downs in forestry equipment, and in hoisting and rigging tasks. They are often used with hooks, slings, and clamps designed for the K63 size family.

Maintenance and safety: Regular inspection is essential. Check for elongation, corrosion, cracks, bent links, or other deformations. Do not exceed the prescribed WLL and replace damaged chains. Store in a dry, clean environment and lubricate joints according to manufacturer guidelines.
