Zusammenfassung:A restricted access lockout system restricts access to remotely operated hydraulically actuated valves by utilizing a processor to compare each user's access code against a stored list. The user access code may be provided by card key with an embedded RFID chip, a designated application on a personal device such as a smart phone or smart pad that may communicate with the processor via Bluetooth, Wi-Fi, Internet, or radio. Once the processor grants access to operate various designated hydraulically actuated valves the designated hydraulically actuated valves are unlocked for designated period of time. After the designated period of time expires the hydraulically actuated valves are relocked. Generally, the lock is via a hydraulic cylinder where the hydraulic fluid may be isolated through one or more solenoid control valves. Hydraulic fluid within the hydraulic cylinder and the cylinder provide a sufficient counter to apply force so that the hydraulically actuated valves may not be manipulated. In certain instances, the hydraulic locks may be replaced by mechanical lock. In other instances, the hydraulic cylinders may be supplied with pressurized hydraulic fluid supply by hydraulic pump wherein the pump is actuated by the processor upon command by a user. The pressurized hydraulic fluid and the hydraulic cylinders may in turn allow the user to remotely actuate the hydraulically actuated valves.
