Kinshofer X-LOCK Coupler Provides Fast and Safe Attachment Exchanges
Kinshofer offers the X-LOCK Coupler, a safe and quick solution for exchanging excavator attachments on the jobsite. The tool allows the operator to exchange attachments safely from within the cab and features a wedge-locking principal, which allows the coupler to connect to the attachment in two separate places, where competitors only feature one locking point. The X-LOCK Coupler easily pairs with buckets, rippers, rakes and mechanical grabs as well as a wide variety of demolition, recycling and railroad attachments.
Unlike the competition, the wedge-locking principal connects the coupler to the attachment in two separate places and provides a two-and-a-half-fold locking force compared to a pendular jaw quick hitch. This constant applied working pressure continuously readjusts the wedge, keeping both pins firmly against the quick hitch.
Two pressure relief valves operate the wedge, which locks at 1,730 psi (119.2 bar) and unlocks at 3,455 psi (238.2 bar). This ensures the hydraulic circuit is not over pressurized and greatly minimizes wear in the locking area between the coupler and the attachment. A rear lock safety device ensures the wedge does not retract and disconnect the attachment if hydraulic failure occurs.
Additional safety features within the X-LOCK Coupler allow the operator to connect and disconnect safely from within the cab. When connecting, the X-LOCK Safety Knuckle immediately and automatically engages onto the front pin, which can only be released by the operator. The self-adjusting wedge locks the second pin as soon as the lock switch is deactivated, safely securing the attachment.
When disconnecting, the operator unlocks the self-adjusting wedge from the rear pin and unlocks the safety knuckle from the front pin. The coupler is now ready to be removed from the attachment. If the attachment is not fully detached within five to 12 seconds, the coupler will automatically reattach for safety. The auto-lock window time period is customizable. Kinshofer offers four models of X-LOCK Couplers, including Hydraulic Pin-to-Pin, S-Style Nordic Style, and Tilt or Tilt Rotation, and Mechanical Pin-to-Pin.
