Calculating rope length
If the rope length is unknown, you can calculate its length by means of the period of oscillation of the hook,
as follows:
•
Swing the hook and measure the time it takes for 10 complete oscillations (an oscillation is the time
the hook takes to swing and return to starting position).
•
Calculate the period of oscillation
T = measurement [
in seconds
] / 10
•
Calculate rope length with the formula:
L = g * ( T / 2
π )
2
Where:
L = rope length in meters.
g = gravity constant [9,81
m/s
2
]
T = period of oscillation
Enter the result in the “H&C SERVICE \known position” parameter when requested during the “rope length
definition procedure”, leaving the hook (trolley or beam) in the same position.
