Vægtklasse
Størrelsesklasse for en gravemaskine ud fra driftsvægten. Den bruges til det første valg af et redskab. Om grænsefladen passer (bolte, armbredde, hurtigskifte), kontrolleres særskilt.
Weight class categorizes excavators by their operating weight (including tracks, counterweight, and fuel). It is a first filter for attachment size, not a fitment check: the interface (pins, stick width, coupler) is verified separately for each machine.
Standard weight classes:
- Mini (1–6 t): Compact excavators for tight spaces
- Midi (6–10 t): Mid-size machines
- Large (10–30 t): General construction machines
- Heavy (30 t+): Quarry, mining, heavy demolition
Why weight class matters:
- Determines hydraulic flow available
- Sets maximum attachment weight
- Affects working envelope and reach
Weight class does not tell you the pin spacing or pin diameter. Those vary by machine and are checked separately.
Matching rules:
- The machine maker sets the permitted weight of attachment and load. We check it before we quote.
- Hydraulic requirements must match carrier capability
- Pin configuration must match or use adapter
Sieruta manufactures attachments for mini, midi and large excavators, and our engineers check the fit against the carrier before production.
