Abstract

Devices for controlling movement of aerial buckets via hydraulic systems. Each hydraulic system has valves that control movement of the aerial bucket. A control head of the device has a joystick that is moveable and encoders that detect movement of the joystick. A valve actuator manifold of the device is coupled between the control head and the hydraulic system and supports valve actuators moveably coupled to the valves. Servo drive systems supported by the valve actuator manifold are coupled to the valve actuators and are controllable to move the valve actuators. A processor module of the device is in communication with the encoders and the servo drive systems. The processor module controls the servo drive systems based on input from the encoders such that moving the joystick controls movement of the aerial bucket.
