<p>The crane has an identification unit to determine a total center of gravity of the crane. A determination unit determines an inclined line of the crane. A stability ensuring unit provides a signal and/or prevents crane movement, when distance of the center of gravity from the line reaches or approximates or exceeds a threshold value and/or when a ratio of a distance of the center of gravity from a rotating assembly midpoint to distance of the line from the midpoint reaches or approximates or exceeds the threshold value. A sliding rail (1) and a pad cylinder (2) are provided in the crane.</p> |
