How a winch works is sometimes complicated to understand, but we know, and would like to share our knowledge with you, to make you choose the right winch first time.

Please take your time and study these subjects. If you have further questions, we will be pleased to help you.

How to choose the right winch?

Cheap price does not work as guideline for getting a good winch

To choose the right winch can be difficult, but if you focus on a few important issues, you will save money and avoid a lot of trouble by getting the right machine from the start.

Many customers makes the mistake not to pay attention to the duty classification:
If you choose a winch made for sporadic use and use it continuously it will create problems.
Unfortunately many customers choose the cheapest product (far East Produce).
You can find 2 apparent similar products with a price difference of 100% having the same effect, but one is constructed for sporadic use the other one for continuous use.
Always choose a product matching your frequency use of the winch.

General tips about using a winch

How to calculate a line pull when the load is going uphill?

All winches are rated on a DEAD WEIGHT line pull and can pull in excess of the rating on rolling loads and wheels.
To calculate your line pull
Line Pull = W*(Gr+CF)
W= Weight
GR= Grade Resistance
CF= Coefficient of friction
For example, if you want to pull a steel bin on wheels up a 30% cement grade with a total weight of 5 tons, What line pull do I need?

Line pull = 5 tons * (.288+.2-.5) = 2.44 tons – 3.94 tons

How to avoid wire jam:

Get the right sheave position:

Angel fleet:

The right fleet angle is important if you wish to avoid wire jams.
The winch must be placed so the wire is getting as close as possible to 90° as possible.
If this is not considered, you risk the wire is placed on one side of the drum, which will damage the winch or the wire.
In order to get a correct winding in angel, a sheave must be used.

The sheave must optimally be placed at a distance of 19x the with of the drum on the winch.

The maximum pulling/lifting force of a winch:

All winch capacities are based on the pulling/lifting force in the first layer of the drum 
The biggest force of the winch is the pulling force on the first layer of the drum.
As more and more rope is added to the drum the drawing/pulling speed will increase but the pulling force decline. (Please study the technical information for your specific winch choice)

If a pulley block (with one wheel) is used the pulling capacity will double, but the speed will be 50% slower.

When using a pulley for heavy duties the amp going through the motor will be reduced, meaning the motor will be less warm.

The winch must have a capacity of 1.5 times the weight to be pulled/lifted. So a winch that must pull 2 tons must have a capacity of 3,5t.

IP: What does it mean?

The IP shows how the product is protected against water and dust etc. Consists of 2 digit numbers

Example:
IP 66 means dust tight and protected against powerful jetting water
