The Cat CW quick coupler can pick up any work
tool and is equipped with a wedge-style locking system
minimizing break-out force loss. The CW is highly
suitable for harsh applications, such as demolition and
quarries. The CW has become the industry standard in
EAME. It is interchangeable with different machine
classes, and has been designed for use with more than
700 different machines, both Cat and non Cat.
The Cat CW Series is available in a spindle and hydrau-
lic version. A spindle version can easily be modified into
a hydraulic version and vice versa.
Additional Benefit:
Hoisting hooks
— To make the CW Series more ver-
satile, hoisting hooks are available from 2 metric tons
(2.2 tons) up to 20 metric tons (22 tons) capacity for
maximum lifting capacity.

CW-40 and CW-40S are not suitable for machine exceeding 27 metric tons
(29.8 ton)
, which are used under heavy working conditions like rocky soils and demo-
lition work, we highly recommend the usage of quick coupler CW-45(S).
