Increase the utilization of your machine

The quick coupling of work tools is an integral part of the philosophy: Increase the utilization of your excavator through work tools. Your machine becomes an all-purpose tool carrier. The CW- coupler has become an industry standard with over 50.000 units sold in the last 40 years. It's interchangeable with different machine classes and has been designed for use with more than 700 different machines, both Cat and non-Cat.

Compliant to safety standards

The CW quick coupler complies with all applicable global safety standards.

Highly suitable in harsh environments

The CW quick coupler design is very robust and the low construction height maintains an optimal break out force. A wedge-style locking system fits the coupler tight to the tool hinges without any play during the entire life. This makes the coupler very suitable in applications such as rip & load, demolition and in quarries.

Performance match with any kind of attachment

Adapter hook sets and mounting brackets are available to adapt nearly any brand and type of work tool to work with the Cat CW quick coupler. This includes hooks/brackets for buckets, hammers, grapples and other attachments.

Service that's second to none

Cat CW quick couplers are sold through the same Caterpillar dealers as Cat machines. That gives you access to an integrated service and support network - a single organisation for machine and work tool parts and service. No other manufacturer can offer you the same.
