Quick couplers connect buckets and attachments to an excavator's stick, cutting tool-change time from minutes with pins to seconds from the cab. Match the coupler to your carrier's weight class and pin dimensions first, then compare the live stock below.

Odabir pravog tipa

Mechanical vs hydraulicMechanical couplers lock with a manual pin or wedge and cost less; hydraulic couplers latch from the cab and suit machines that swap tools many times a day.
Pin-grabberGrabs the attachment's existing pins, so most buckets in the carrier's class fit without modification; the most common style on used stock.
Dedicated systems (S-type, CW, OilQuick)Standardised interfaces common on Nordic and central-European machines; attachments must carry the matching adapter, so check the system family before buying.
Tilting couplersAdd one or two tilt axes between stick and tool for grading work; heavier than a plain coupler and reduce breakout force slightly.

Što provjeriti prije kupnje

Carrier matchCoupler weight class, pin diameter, and pin centres must match the excavator's stick; a coupler from the wrong class is unusable regardless of condition.
Safety lockingLook for a positive front-pin lock and a working blocked-valve or check-valve arrangement; many jurisdictions require a double-locking design.
Wear and playCheck the jaws, wedge, and pin bores for elongation; visible play between coupler and bucket pins accelerates wear on every attachment used.
Hydraulic linesOn hydraulic couplers, inspect hoses, the control valve, and the in-cab switch; a leaking latch cylinder is a safety issue, not just a maintenance one.

Česta pitanja

Will a used coupler fit my excavator?

Only if the weight class, pin diameter, and pin-centre spacing match your stick; check the machine's coupler chart or measure the stick nose before buying.

Mechanical or hydraulic?

Hydraulic pays for itself when you change attachments several times a day; a machine that runs one bucket all week does fine with a mechanical coupler.

What is a pin-grabber?

A coupler that clamps the attachment's own pins instead of a dedicated interface, so it accepts most standard buckets in the same size class.

Do couplers need certification?

Many markets require a positive-locking design and periodic inspection; ask the seller for the CE marking and any inspection records with the sale.
