A sling access handle member attached to at least one of the sling ejector plate members and used to manually rotate the ejector plate members from an open position for receiving the sling members therein and into a closed position, wherein the sling member are locked upon the hook portion of the main plate member. A remotely controlled solenoid mechanism attached to the main plate member and adapted to unlock the locking mechanism, and a first traction spring member adapted to bias the ejector plate members into the open position and force the sling members off of the hook portion. A remote control mechanism adapted to remotely activate the solenoid mechanism, to force the sling members off of the hook portion. |
