# Winch Power Range Calculator

Posted by Dinesh onCalculate **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

### Formula:

PRw = [(LP × LS) / (C × Er)]

where: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
