Caterpillar launch new range of HCS couplers
Latest hydraulic units improve safety, boost productivity and extend maintenance intervals
CATERPILLAR say they are raising the bar in operator and on-site safety by introducing their Hydraulic Connecting S Type (HCS) couplers, which offer the ability to switch hydromechanical attachments in seconds without leaving the cab.
The HCS coupler line-up – which comprises five models – has been designed for use on a wide range of Cat machines, from 311-340 tracked excavators to M314–M222 wheeled machines. According to Caterpillar, the HSC couplers deliver 37% better flow capability than competitor units on the market.
The hydraulic couplers have been specially engineered for high-flow performance suited to hydromechanical tools in demolition and in city earthmoving applications. The lower hydraulic restriction results in better machine fuel efficiency. With the minimal amount of time to transition between attachments, operators will be more inclined to switch attachments when needed and use more task-appropriate attachments when required.
The HSC system’s quick disconnect design prevents contamination, whilst the frame protects important hoses and components from being damaged inside the coupler.
The Cat HCS couplers also feature industry-leading sensor technology and multiple measures to keep attachments connected in the event of a hydraulic pressure loss. The hydraulic coupler also gives visual and audible cues, as well as confirmation on the machine’s in-cab screen of a successful connection to the attachment.
