Fast and Safe Excavator Attachment Exchanges

KINSHOFER presents the X-LOCK coupler as a safe and quick solution for exchanging excavator attachments from within the cab on the jobsite. Other features of the coupler include:

• A wedge-locking design that, allows the coupler to connect to the attachment in two separate places and provides a two-and-a-half-fold PSI locking force.
• Easy pairing with buckets, rippers, rakes and mechanical grabs, as well as demolition, recycling and railroad attachments.
• Two pressure relief valves, which lock at 1,730 PSI and unlock at 3,455 PSI, that operate the wedge, ensuring the hydraulic circuit is not over-pressurized, and minimizing wear in the locking area between the coupler and attachment.
• A rear lock safety device to ensure the wedge does not retract and disconnect the attachment if a hydraulic failure occurs.
• An X-LOCK safety knuckle that immediately and automatically engages onto the front pin when connecting, which can only be released by the operator.
• A self-adjusting wedge that locks the second pin as soon as the lock switch is deactivated, safely securing the attachment.
• The ability to unlock the self-adjusting wedge from the rear pin and unlock the safety knuckle from the front pin, but the attachment is not fully detached within five to 12 seconds, the coupler automatically reattaches for safety.
• An X-LOCK control unit to allow operators to control and monitor the attachment exchange process in the cab.
• Red and green LED lights and a warning buzzer to indicate whether the pairing was successful or not.
• Availability for excavators with 2,200- to 220,000-pound operating weights.
• Simple and safe installation, with one hydraulic circuit and two hydraulic hoses.
• Four models hydraulic pin-to-pin, s-style Nordic style, tilt or tilt rotation, and mechanical pin-to-pin.
