WINCH CAPACITY CALCULATION

WINCH CAPACITY CALCULATION

WINCH CAPACITY CALCULATION

(OP)
I AM TRYING TO CALCULATE THE LINE PULL OF A WINCH DRIVEN BY
A HYDRAULIC MOTOR WITH A OUTPUT TORQUE OF 4022NM AND A DRUM
DIAMETER OF 300MM WHAT IN KGS WOULD THE WINCH LIFT

RE: WINCH CAPACITY CALCULATION

F=Torque/Effective Winch Radius

Assuming direct drive and on gear loss

RE: WINCH CAPACITY CALCULATION

To calculate this properly,

4022 X 90% (mechanical efficiency assumed) divided by effective radius of capstan (in metres) 0.15 divided by acceleration due to gravity 9.81 mtrs/sec squared

Therefore 4022 x 90% / .15 / 9.81 = 2459.94 KG

RE: WINCH CAPACITY CALCULATION

how to calculate the amount of cable held in a winch?
Thanks

RE: WINCH CAPACITY CALCULATION

Hi leep

While I agree with boo1 and here to chill, your capacity to lift will be limited by the tensile strength of the cable, also bear in mind as the cable wraps onto the winch drum the torque requirement to lift will also increase.
Can you provide more details like speed of lift, cable strength etc, remember also that when starting to lift the cable as to accelerate the load from rest.

You may not get a response from leep, as I note that OP date was Dec 19 2001, and leep has not visited the site since then!

Try 2 x π x mean radius x number of turns

Good Luck
