Double Lock Hydraulic Quick Coupler

Double-Hydraulic-Quick-Hitch-Coupler (10)

Compared with a traditional quick coupler, we add another auto-lock on its front hitch ensuing double safety. Independent hydraulic system, the front lock still works well even when inner leakage happens. The front lock will lock the pin from dropping off when the rear tiger mouth or cylinder rod is broken.

Main Advantages

Fit to 2.5-90 ton machine; Q345B material with advanced mechanical design; Long service life.
Driven by a hydraulic system, the operator can easily switch attachments by turning on the switch in the cab.
Equipped with a check valve on the cylinder, the attachment will not drop off even when some failures happen like hoses burst.
