Overview

Cat® Hydraulic Connecting S Type Couplers connect to your machine's hydraulics and electronics giving you the ability to pick up an attachment with full functionality in seconds without leaving the cab. These couplers deliver the productivity and versatility benefits you expect from a coupler. Additionally, they bring safety to your people, equipment, and overall operation while increasing the life of the other attachments in your fleet.

Features At A Glance

Displaying 1-6 of 5

Better Hydraulic Flow

Couplings are machined and sized for the high-flow performance required by hydromechanical attachments.
Better hydraulic flow results in fuel efficiency gains from reduced back pressure.
Enclosed spring prevents contamination of hydraulic system.
Durable and reliable fluid connections create a system for hydraulic fluid flow and no opportunity for spills during tool exchange.
Internally routed hoses in the bracket and coupler use fewer external hoses, reducing overall hose and repair costs.

Change Attachments Faster

Changing attachments with hydraulic connecting couplers is 98% faster than pin-on.
Using hydraulic connect couplers instead of mechanical couplers saves 96% time in changing attachments.
Quick disconnect design improves lifespan and is easy to service.
Design of cover lid and sealing adds protection for couplings and prevents contamination to hydraulic system.
Machined position of the quick disconnect valves on the tool and on the bracket ensure a tight and reliable connection limiting chance of leaks or damage.
Quick disconnect couplings are installed in the same direction as the locking force with a solid flange to ensure a solid fit. No locking rings or nuts which increase the chances of loose or broken parts.

Industry-leading Safety

Industry-leading safety features in sensor technology.
Safe coupler locking complies with updated European EN474 safety standard.
Keep everyone on the job site safer. The operator stays safe in the cab and no assistance is required to connect or disconnect hydraulic hoses during attachment changes.
Multiple electronic and mechanical measures in place to keep attachment secure, even if a pressure loss occurs.
Operator has visual and audible confirmations from inside the cab of successful attachment connection.
Heavy-duty locking wedge design keeps connections tight and in place during use.

Additional Versatility

Attachment switching with a hydraulic connect coupler:
- Quick changes mean operators will utilize task and application appropriate attachments, increasing overall productivity and extending the life of the attachments.
- The ability to exchange attachments easily can reduce the number of machines needed for a job.
- Fast attachment changes with the hydraulic connecting interface will save time over static couplers or pin-on attachments.
Electric connector allows for full functionality when working in combination with tiltrotators, ditch cleaning tilt buckets, and mulchers or other attachments with electronic harnesses for grade sensors or tool functions.
Each coupler comes standard with a lifting hook with 5-, 8- or 10-ton lift capacity depending on the size class.

Boost Efficiency and Productivity with Integrated Technologies

The Cat® PL161 attachment locator keeps track of attachments across every jobsite with Bluetooth enabled location visibility.
Monitor attachment utilization by capturing real working hours for smarter maintenance planning.
View machines and attachments together in VisionLink™ for full fleet visibility and management.
Rugged, maintenance-free design with up to two years of battery life.
