12000 lb winches contain high capacity that can haul those objects which are 12000 pounds. These winches are mostly with 2 Amps. It means a winch can handle a minimum of 2 Amps of current before it gets a start or before overheating. Winches with high Amps have more capacity to draw current than winches having low capacity. Thus choosing the right one is the most important thing.

How many Amps does a 12000 Lb winch draw & its wire size?

When you are about to choose the right 12000 Lb winch, you must remember one thing that the wire must be thicker because thicker wires consist of the strongest pull. If you are confused about the wire size you can go with thicker wires as they will accommodate the weight as well as strength.

Some standard sizes of 12000 Lb winch are 22AWG, 24AWG, and 26AWG. 24AWG is the most applicable one of all. All winches are the same. Its sizes are changed based on the manufacturer and the weight rating. For instance, 12-volt and 24-volt have different capacities to pull Amps. 

It is suggested not to use batteries if it is not mentioned. Before using, read the manufacturer’s specifications and instructions for user manuals. Winches usually consist of large capacities and can haul things that are 12000 lbs. The best winches are particularly trait in nature and low amp draw.

A battery loses a large amount of energy when a winch takes place.  A winch uses a low amount of electricity if it consists of a low amp draw. Thus you may need to utilize your battery with an excellent Amp rating. Selecting the right battery for a winch is a crucial thing as high-capacity winches consume more electricity. 

A winch demands a certain amount of electricity based on its weight it is on and its usage time. For instance, it can be said that a standard 9,000 pound can consume 60-70 amps without load. A 4,000 pound can draw 250 amps and 480 amps roughly at 9,000 pounds.

It means when it comes to 400 pounds it can draw 250 amps and 9,000 pounds can draw 480 amps. It is a significant sum to show an instance. But one should remember that the pulling strength of a winch is frequently transient. A winch cannot draw much power for a long time except in conditions. If you use winches often it is recommended to upgrade the battery to reserve a larger capacity than stock. Before using, check the alternators and batteries’ overall condition. 

Factors affecting AMPs draw rate

If you are puzzled about how much power your winch consumes, you should contact the manufacturer. You can also get the winch details on the product page or in the instruction section. Many winch manufacturers often offer free amps to make you ensure your needs. If you need a capacity over 100lbs you should consult the governing body before using it. Various factors depend on AMPs’ draw. The factors are discussed below:

1. The Type Of Battery Being Used

The most common battery that is used is a lead-acid battery. The lead-acid battery has a high weight and consists of a low amps rate. For a 12000 lb winch, you can use a lead-acid battery and a thicker wire to accommodate the power and weight of the battery. If you are looking for the best performance for a battery you need to plan for your electric winch.

Before you purchase a battery for your electric winch, make sure you are not buying a low battery. Otherwise, your winch won’t perform well despite its low capacity. To work your winch properly the juice for the winch is required. For instance, for a 12000 lb electric car trailer, a 12-volt battery is required.

The best thing is you will have a recommended battery rating thus it won’t occur hard for you to find the exact requirement. The size and weight of the object being hauled 

Another important factor that affects the draw amps rate is size and weight of an object to be hauled. If the object is large, it needs thick wire to handle increased weight. You need to ensure that the weight must be low compared to the overall capacity of a winch. 

If you want to enhance the pulling power with 12000 lb winches, you can use double line technique. Before selecting an object, you need to choose the right winch. If speed is the priority you need to purchase a large winch. 

2. The width and length of the cable being used

The width and length of the cable take another essential place to draw the amps rate. A thicker cable is always required for a high amount of amps. A winch line diameter should be measured with the strength of the winch line. According to Master Pull[1], 1.5:1 and 2:1 is safe to use with the winch.

The winch line must have a breaking strength to load 1.5:1 and 2:1 times pulling power. For instance, if you are using a 9000 lb pulling capacity, the line must have a breaking strength from 13000 to 18000 lbs or more than that. You can put a larger diameter cable for additional strength. A cable should be 150 ft in length. 

3. Type of winch

The type of winches has an essential part in the amps rate. Many winches are manufactured with lower amps and many with high amps. For instance, it can be said that a lower-capacity winch may load 600 amps or less and a high winch can load 1000 amps or more than that. The winches can be defined by many devices that wind up or wind out.

The operating sound may seem simple but it enables the winch for multiple purposes that often can be found in tracks, ships, or wakeboarding parks. Nowadays various kinds of winches can be found in the market. The types of winches are lever winch, snubbing winch, air winch, capstan winch, capstan winch, glider winch, mooring winch, and wakeskate winch. 

4. Terrain or surface being pulled over

The terrain or surface also affects the amps draw. A rough surface can provide more volts to move a similar weight as a smooth surface can. The power source is an important thing to draw amps. Hydraulic winches are usually used in vehicles’ steering pumps. Electric winches are linked with vehicle batteries and electrical winches. An electric winch is the most common one of all. If you are about to purchase an electric winch, make sure you are getting the right one.

5. The winch’s operator

This is another essential factor. An experienced person may draw high amps but a beginner should start with low amps. For operators, certain skills are available to accomplish their responsibilities. To become an efficient winch operator you need to know how much education is required.

According to the research, 7.7% of operators belong to bachelor’s degree and 3.8 winch operators belong to master’s degree. 

One can think about what kind of career a winch operator would be. A winch operator can imagine their career through a career progression. For example, one can start their career by being a crane operator. Through progress, he can be a foreman and eventually can gain the title ‘winch operator’ or truck driver. 

6. How tightly the cable is held against the object ?

A loose cable usually allows more current flow through the wire which can increase the amp draw. On the other hand, a tight cable can cause damage to the wire. It cannot load the power from the winch. To prevent damage one should make the cable loose. Cables of winches are installed with a heavy-duty diesel.

For installation LV MV HV power cables are required. Synthetic cable is the best cable because it can help to recover from many situations. A cable should be 10k pounds, the safety factor about the cable is 5X and a cable should be firmly secured at all times.

7. The weather conditions

The weather is another important fact to determine the rate of amps. High wind can help to move the cable and more quickly increase the amp’s power. Winch operators must be cautious about a few things regarding weather. For instance, ice should be removed before use because it may cause damage to the winches.

Before using winches, try to check the cables whether it is seated securely in the pulley.  In cold weather, if you hear a ratchet sound while using the winches, test it. A cable should be held in its place without losing tension when you release the handle.

8. How well the winch is lubricated ?

Lubrication plays an essential role when it comes to the rate of amps. An ideal cable lubricant must be thin for better application. There are mainly two types of cables to lubricate, external and eternal. A lubricant must be clear in color because it makes it easier to inspect the cable for potential fraying. The lifespan of a cable mostly depends on maintenance. The right method of lubrication is important because it removes the friction between the individual wire strands. It also helps to protect against corrosion.

How do control winch amps draw?

There are various ways through which the amps draw can be controlled. Such ways are: 

  •  Adjust cable tension: a cable must be loosened to get the high amps. A tightened cable can cause low amps or damage. 
  •  Lubricate the winch: lubricant should be applied during friction like the motor or gears. 
  •  Adjust the winch motor: you need to change the motor if it is overheating or causing problems. 
  •  Repair the winch: if any problem occurs with the winch, inspect it and repair it or change it. 
  •  Check the damages: if you get a sign of damages such as broken wires or overheating or missing parts, replace it. 

Summary

In conclusion, it can be said that 12000 lb can draw 1 amp per rotation. Before purchasing a winch one must be ensured about the winch along with its cables. A winch can be controlled by using various methods over it. One should remember the weight and size of the object before pulling. A winch and the cable must be checked frequently whether it is running properly and the cable should be maintained according to the needs.
