Faster to use than previous models, the three new Cat hydraulic connecting CW (HCCW) coupler models connect seamlessly to the machine’s hydraulics, allowing operators to switch between hydraulic attachments with full functionality in seconds from the safety of the cab.
Compatible with any Cat hydraulic attachment, the HCCW20, HCCW30, and HCCW40 quick couplers are designed for tool carrier capacities ranging from 7.5 to 27 tons. Each model offers a standard 10-ton lift capacity.
The exclusive locking control system feature and sensor technology measure locking wedge position and indicate coupling status to the operator. Complying with the European EN474 standard, multiple electronic and mechanical measures secure the attachment, even in the event of pressure loss. Visual and audible confirmations inside the cab tell the operator when the attachment is connected.
The design features enhanced hydraulic flow to reduce restriction, minimizing heat build-up and reducing engine power requirements. Machined for high-flow performance, the couplings ensure hydromechanical attachments operate at full capability with limited back pressure. Reliable hydraulic fluid connections help prevent spills during attachment changes, and the quick-disconnect design improves lifespan and facilitates easy servicing.
Customers with existing Cat excavator fleets using CW hinges do not need to retrofit their machines to use the HCCW quick couplers. Fabricated tools, such as buckets, can seamlessly switch between existing CW and HCCW couplers. Hydraulic coupling (HC) brackets allow the use of existing hydromechanical tools like shears, hammers, and grapples with the HCCW.
Internally routed hoses in the coupler and bracket protect against damage and reduce overall hose and repair costs. The quick-coupler platform includes durable male and female quick disconnects located in the coupler and attachment bracket. The cover lid and sealing provide added protection for couplings, preventing hydraulic system contamination.
