JCB Attachments has developed a double locking quickhitch that features independent locking of the front and rear pins.

Designed for use with tracked excavators including the JS130 through to the JS460 and the wheeled JS130W to the JS200W, the hitch is compatible with both genuine JCB buckets and JCB scoop buckets, along with the full range of JCB-powered attachments.

The Dualock uses a blocking bar system from the BUG coupler to secure the rear pin lock. In addition, a mechanical front lock secures the front pin independently of the rear.

The face of the front locking mechanism is painted red and can easily be seen from the cab, ensuring the operator can be confident that the bucket is securely fastened before operating the machine.

To open the hitch, the operator completely crowds the hitch towards the machine. The hitch button in the cab is pressed and the operator has to acknowledge the warning buzzer in the machine’s Advanced Monitoring System (AMS) screen on the dash console.

The operator then rotates the hitch to locate onto the front and rear pins of the bucket.

The bucket is fully crowded and the operator again presses the hitch lock button in the cab. A ‘Check Q/H’ message is displayed on the AMS screen. Then, by operating the bucket crowd service, the locking jaw is activated, and the bucket or attachment is locked in position.

The operator makes a visual check of the front lock, tests that the bucket is secure, and then presses the acknowledge button once more to cancel the buzzer, before proceeding.
