Caterpillar introduce new HCCW couplers for excavators

27 May, 2024

The new Cat Hydraulic Connecting CW coupler seamlessly connects to the machine’s hydraulics, allowing the operator to pick up an attachment (eg Cat P324 Primary Pulverizer) with full functionality in seconds from the safety of the cab

Latest Hydraulic Connecting CW quick-couplers deliver fast and safe attachment changes with less spillage

BUILDING on decades of field success with the CW coupler platform, Caterpillar have announced the launch of three new Cat Hydraulic Connecting CW (HCCW) coupler models. Connecting seamlessly to the machine’s hydraulics, HCCW quick-couplers allow operators to switch between hydraulic attachments with full functionality in seconds from the safety of the cab.

Compatible with any Cat hydraulic attachment, quick changes with the HCCW units give the operator the ability to use the right attachment for the job, increasing overall productivity and tool utilization. Fast attachment swap outs with the hydraulic connecting interface can help save time over static couplers or pin-on attachments. The field-proven CW coupler platform is designed and built to last and keep costs low for end-users.

The new HCCW20, HCCW30, and HCCW40 quick-couplers work with a range of tool carrier capacities, from 7.5 to 27 tons. Each model offers a standard 10-ton lift capacity and an exclusive Locking Control System feature/sensor that measures the locking wedge position and indicates the coupling status to the operator.

Complying with the European EN474 standard, multiple electronic and mechanical measures help to secure the attachment, even in the event of pressure loss. There are also visual and audible confirmations inside the cab, to inform the operator of a successful attachment connection.

The new HCCW design features enhanced hydraulic flow to reduce hydraulic restriction, minimizing heat build-up and reducing the amount of engine power required for operation. Machined and sized for high-flow performance, the couplings ensure hydromechanical attachments operate fully with limited back pressure. Their reliable hydraulic fluid connections help to prevent spills when changing the attachment, while the quick-disconnect design helps improve the lifespan and facilitates servicing ease.

Customers with existing Cat excavator fleets using CW hinges do not need to retrofit their machines to use the new HCCW quick couplers. Also, fabricated tools, such as buckets, can seamlessly switch between existing CW and new HCCW couplers, while new Hydraulic Coupling brackets allow the use of existing hydromechanical tools like shears, hammers, and grapples with the HCCW.
