Material
Stålsorter och komponenter
Hardox®
Abrasion-resistant quenched and tempered steel manufactured by SSAB, designed for extreme wear applications.
Strenx
High-strength structural steel manufactured by SSAB, enabling lighter yet stronger attachments.
Slitplåt
Replaceable steel plate designed to absorb abrasion and protect the main structure of an attachment.
Brinellhårdhet (HBW)
A standardized measurement of material hardness, critical for predicting wear resistance in excavator attachments.
Redskap
Redskap och utrustning för grävmaskiner
Snabbfäste
A mounting frame between the excavator arm and the attachment that lets the operator change attachments quickly, by hand or from the cab depending on the type.
Grävskopa
The primary digging attachment for excavators, available in specialized designs for different materials and applications.
Skär
The front wear component of a bucket that penetrates material first; welded, or bolt-on/reversible for field replacement, depending on the configuration.

An advanced quick coupler providing 360° continuous rotation and ±45° side tilt for maximum attachment versatility.
Maskiner
Specifikationer för bärare
Viktklass
Excavator size category based on operating weight. Used for initial sizing and preselection of an attachment; interface fit (pins, stick width, coupler) is verified separately.
Bultavstånd
The centre-to-centre distance between the mounting pins. It varies by machine and by interface, and is checked separately from operating weight.
Standarder
Certifieringar och krav
EN ISO 3834-2
International quality standard for fusion welding of metallic materials, requiring comprehensive quality management.
ISO 13031
Safety standard for quick couplers on earth-moving machinery, specifying requirements that guard against accidental attachment release.
CE-märkning
European conformity marking applied where EU harmonisation legislation covers the product; it declares conformity with the applicable directives and regulations, not a quality grade.
Materialintyg (MTC)
Document certifying the chemical composition and mechanical properties of steel used in manufacturing.
