The horizontal position control card, is an electronic device which verifies the planarity of gravity baskets installed on hydraulic cranes and blocks the machine in case of dangerous events for the people inside the basket.
The leveling of the basket is obtained in a passive way, leaving it swinging until it reaches the balance position.
When it is stabilized, it is blocked, to allows the operator to work. If the horizontal position is lost, the card, through dedicated outputs, can alert the operator of the new dangerous situation or eventually lock the machine.
