Hydraulic Cylinder Lock

Hydraulic cylinder with check, relief and pressure control valve included. LCS incorporates an electronic position sensor integrated into the quick coupler hydraulic cylinder. This sensor provides precise and reliable input to an electronic processor mounted inside the quick coupler. This microprocessor provides digital communication to the Next Generation MHE machine (ECM) by way of an electrical harness.

Locking Indicator

The visual verification rod allows the operator to visibly confirm, from the cab, that the coupler has successfully locked the attachment into place properly.

Lifting Hook

Integrated lifting hook allows the operator to switch tasks to lifting without changing tools or coupler.

Low Profile/Build Height

Low build height quick coupler with minimal offset results in minimal break out force reduction.

Protected Components

All components integrated inside the coupler housing and protected against contaminants and potential force impact.

Wedge Type Locking Mechanism

Wedge type locking mechanism minimizes impact loading into the hydraulic cylinder.

Locking Control System

Locking Control System (LCS) incorporates cylinder positioning sensing and provides electrical feedback to the machine which requires Cat® software to display locking system status.
