A hydraulic system for controlling bleed down and retraction of a boom within a safety envelope includes a backup battery power supply, and at least a first boom lift hydraulic cylinder configured to raise and lower the boom. The first boom lift hydraulic cylinder includes a solenoid bleed valve electrically connected to the backup battery power supply. The hydraulic system also includes an input device controllable by an operator of the boom. The input device may, for instance, be used by the operator to initiate bleed down and retraction of the boom from an elevated position. To accommodate independent failsafe features of the system, the input device is configured to selectively actuate the solenoid bleed valve using electrical power supplied from the backup battery power supply.

The present invention relates generally to a DEF tank hydraulic jack adapter plate. The adapter can be fixedly or removably attached to the top surface of an existing hydraulic jack such that the jack can be used to remove or replace a DEF tank from a diesel vehicle. Accordingly, the adapter secures a tank to the plate body of the adapter via a plurality of frame arms which attach to the vertical plates of the plate body. The adapter ensures the tank is retained upon the adapter and subsequently on the jack.
