RAYATTACHMENTS
Quick couplers (also called quick hitches) are used with constructionmachines to allow the rapid change of buckets and attachments on themachine. They remove the need to use hammers to manually drive out andinsert the mounting pins for attachments. They can be used on excavator,mini excavator, backhoe loader and so on.
We can supply four type: hydraulic type, Double lock type,Tilting type andMechanical type.
Advantages
1. Superior power and high efficiency.
2. Maximizing productivity and reliability.
3. The strongest durability one the same class prolongs its life.
4. Simple & easy maintenance, less downtime.

1.Convenient and Efficient:
RAY quick coupler can be used on excavator to exchange accessories (such as breaker, ripper, compactor, grapple, shear, etc)
easily and quickly, enlarging the use scope of excavator. Installing one quick hitch to
the excavator takes only 1 minute, enhancing the working efficiency of excavator.
2.Double Safety System
Check valve Protection System: each cylinder installed safety check valve ensures that quick hitch coupler
can work when the circuit and oil circuit is cut off.
Safety Pin Protection System: security protection is customized for each excavator according to the different
measurement. In the case of the failure of cylinder, quick hitch can work regularly.
3.One Body Design
Increasing durability 10 times more than the couplers with welded parts
