MS System 1 — mechanical quick coupler
The MS System 1 is Sieruta’s own-manufactured mechanical quick coupler for mini and compact excavators in the 2–6 t class. Fabricated in-house from HARDOX-reinforced steel, it lets a single operator swap buckets and attachments in seconds without leaving the cab support equipment, cutting idle time on mixed-task sites. The MS interface geometry matches Sieruta’s own bucket and attachment range for a guaranteed fit, while the fail-safe mechanical lock keeps the attachment secured under load. Pin diameter 45 mm and 250 mm pin spacing suit the common 2–6 t carrier population. Built to Sieruta’s ISO 3834-2 welded-fabrication standard and CE marked. Contact our team to confirm the correct coupler for your carrier and attachment set.
