An adjustable vault apparatus for use on a ground surface includes a base and a pair of linear actuators mounted vertically at opposing sides thereof. Each linear actuator is adapted to move a bar support thereof vertically between a lowered position and a raised position. The bar supports are mutually opposing and adapted to support one end of an elongated jump bar at a bar trough thereof, by gravity. Each linear actuator moves the bar support in accordance to a control circuit electrically connected with each linear actuator and a power source. A control signal received by the control circuit, either wirelessly or by wired connection, causes the control circuit to actuate each linear actuator to either raise or lower each bar support in unison, and the jump bar.
