Used Quick Couplers: All Brands and Machines

Used quick coupler systems cover a broad range of machines: mini excavators from 1 to 3 tonnes, tracked excavators from 6 to 30 tonnes, backhoe loaders, and wheel loaders. Each weight class corresponds to specific pin diameters and spacing, making compatibility between the machine and coupler absolutely critical.

An operator who frequently switches tools—moving from an excavation bucket to a breaker, then to a grapple—saves considerable time using this type of equipment.

The available catalogue includes references for all major brands in the construction sector, ranging from common models to more specialized references. Whether your machine is recent or older, finding a suitable used quick coupler remains entirely feasible.

What is the role of a quick coupler on a mini excavator?

• Mounted between the dipper arm and the tool, it acts as a mechanical interface to connect buckets, compactors, or augers.
• On confined job sites, it enables multiple tasks without needing several distinct machines.
• The integrated locking system secures the tool firmly, even under stress or heavy vibrations.
• Without leaving the cab, the operator can swap a ditching bucket for a trapezoidal bucket in under a minute.
• It fits pin diameters from 35 to 45 mm depending on the mini excavator’s size, making correct reference selection essential.
• For hydraulic models, cab controls eliminate manual handling of locking pins.
• Its presence directly increases the profitability of a compact machine on multi-task job sites like network installations.

Types of couplers: mechanical, hydraulic, tiltrotator

Three main categories structure the market: mechanical couplers, hydraulic couplers, and tiltrotators. Each meets distinct job site requirements.

The mechanical coupler operates by manual locking using a pin or a release key—a robust, economical solution widely used on mini excavators under 6 tonnes. The hydraulic coupler allows tool changes directly from the cab via the machine’s hydraulic circuit, offering a real operational advantage on high-pace sites.

The tiltrotator goes further: it enables 360° rotation and tool tilting up to ±40°, providing unparalleled precision especially for pipeline laying or slope shaping. Brands like Engcon and Steelwrist are well-known leaders in this segment.

Used mechanical quick coupler

• Used mechanical models often provide 40% to 60% savings compared to new units, with equivalent performance.
• Before purchase, checking the locking hook condition and pin wear is essential to avoid excessive play.
• Brands such as Arden Equipment, Morin, or Verachtert offer reliable used mechanical couplers widely available on the market.
• This type of coupler suits sites where tool changes are infrequent throughout the day.
• CE certification must be present on the purchased part, ensuring compliance with current European safety standards.
• A used mechanical model from a machine with fewer than 5,000 hours generally provides very satisfactory remaining service life.
• Traceability, including the original machine identification, facilitates compatibility verification with your own equipment.

Used hydraulic quick coupler

The used hydraulic quick coupler is ideal for sites requiring frequent tool changes. This system allows accessory swaps without leaving the cab, reducing downtime and optimizing productivity. By automating the locking, the operator transforms the excavator into a versatile tool carrier, able to switch instantly from a bucket to a breaker.

Choosing a second-hand version grants access to this advanced technology at a competitive price. These couplers retain full operational capacity and integrate smoothly with existing hydraulic circuits. References such as Verachtert CW20 couplers offer proven durability on the field, even after years of intensive use.

A thorough technical inspection before purchase is essential. Check the seals’ condition, ensure no leaks on hoses, and verify proper functioning of safety valves to guarantee optimal locking under pressure. Regular preventive maintenance and proper lubrication will significantly extend the lifespan of your used equipment.

Available brands: Caterpillar, Liebherr, Volvo, Mecalac, JCB, and more

The Codimatra catalogue covers leading construction brands: Caterpillar, Liebherr, Volvo, Mecalac, and JCB are among the most requested references, with couplers adapted to every machine range and weight class.

Each manufacturer develops its own pin geometry and spacing, making compatibility between brands impossible without an adapter. For example, a Liebherr coupler for an A916 excavator does not directly fit a JCB JS220.

Stock is continuously updated, enabling references for machines produced both in the 2000s and recent models. For less common equipment, such as certain Mecalac models or JCB 3CX backhoes, specific parts remain accessible thanks to regular sourcing from machines nearing end-of-life.
