How to Choose a Winch


Choosing an Industrial Winch

  1. Determine the line pull required.
  2. Determine the size (diameter) and length of cable required.
  3. Where will the line load occur – on the first layer of cable on the drum barrel? The second? The third?
  4. Select the proper winch model and determine the first layer rating required (all winches are rated based on first layer)

Example: Customer A has an application that requires a 5,000 lbs. line pull and has selected 80 ft. (24.3m) of 3/8 inch (9mm) diameter cable as the optimum length. This application would require a low mount hydraulic winch.

Referring to the performance data for low mount hydraulic winches, 80 ft. of 3/8 inch cable will build up to three layers on a model H-200 winch and the winch provides 5,700 lbs. (2,580 kg.) maximum allowable line pull on the third layer. The line speed on this layer would be 17.5 ft./min. at the maximum hydraulic system flow of 15 GPM. Line speed on the first layer would be 12.6 ft./min. Also, note that the required hydraulic system pressure is 1,550 PSI minimum.

Customer A would therefore select our Model H-200 winch with 8,000 lbs. first layer line pull rating as the best choice.

Choosing an Off-Road Winch

Choosing the right winch for your needs may seem complex, but it's actually quite simple. Two pieces of information, vehicle weight and line pull, are required to choose the right winch. To calculate your vehicle's Gross Vehicle Weight (GVW), start with the vehicle's curb weight and then add the weight of the supplies and equipment you'll typically be carrying. The rated line pull of the winch must be high enough to pull your vehicle's GVW while overcoming resistance encountered when you are stuck or on an incline. Ramsey recommends that you select a winch with a rated line pull at least 25% greater than your GVW.
