Abstract (en)
[origin: US2019092606A1] A method for securing a luffing jib crane includes: acquiring a lifting/lowering setpoint; piloting a lifting motor by a converter that applies a motor command speed as a function of the setpoint; driving, in lifting or in lowering, the jib by a lifting cable under the action of the lifting motor; calculating, by a control/command system, a lifting/lowering theoretical angular speed from the motor command speed or from the setpoint; calculating, by the control/command system, a lifting/lowering actual angular speed from a jib angle measured by an angle sensor; comparing the actual angular speed and the theoretical angular speed; and commanding the stopping of the lifting motor according to the result of the comparison.
