Abstract (en)
[origin: CN115028072A] A method for controlling the hoisting of a suspended load (9) by means of a hoisting winch (6) integrated with a drum (62) on which a hoisting rope (60) is wound and coupled to the load, the method comprising: measuring a hoisting speed and mass parameters representative of the mass and displacement speed of the load; supervising an emergency stop device (4), which, once activated, closes the hoisting winch; during the rising period of the load, comparing the hoisting speed with a low threshold value and a high threshold value, the low threshold value and the high threshold value changing according to the quality parameter; the hoisting is monitored in an optimized mode in which the hoisting speed at the rise is allowed below a high threshold and prohibited above the high threshold, and an alarm is initiated if the emergency stop device is activated during the hoisting while the hoisting speed is above a low threshold.
