Note: The JRB Excavator Coupler is designed to be locked when there is no electrical power. In
other words, the coupler is locked by default. Electrical power is required to unlock the coupler.
The system shown is in the LOCKED position (no electrical power to solenoid). System pressure applied
to bucket cylinder line “A” or “B” is transferred through valve port C2 or C1 respectively. The pressure is
then sent through CV1 or SV2/CV2, through solenoid valve SV1 and charges the head end of the coupler
cylinder. The system maintains a positive force on the locking plate at all times while the bucket cylinder
is pressurized.
With the switch in the UNLOCK position (electrical power applied to both solenoids SV1 and SV2) and line
A pressurized; pressure is transferred through CV1 and SV1 and energizes the rod-end of the coupler
cylinder to retract the coupler locking plate. Hydraulic fluid from the head end of the coupler cylinder moves
through the “EXT” port back through SV1, CV3, and SV2 and drains into line B. When line B is energized,
the locking plate can not be retracted.
