Winch Power Range Calculator

Posted by Dinesh on

Calculate power range for a winch application by using this simple pump and motor hydrostatic transmissions calculator online.

When line pull and line speed in the normal working range are known, the Power Range for a winch application can be found using the following formula:

PRw = [(LP) * (LS)/ C *(Er)]

Power Range for a Winch Calculation


PRw = [(LP × LS) / (C × Er)]

LP = Line pull (lbs or Newtons)
LS = Line speed (ft/min or meters/sec)
C3 = A constant to convert to units of power (HP: 33000, Kw: 1000)
Er = Final drive ratio efficiency
