What is a Winch Strap?

A winch is a machine with a vertically installed winch, which can be wound under power, but does not store ropes. It also refers to a winch with a rotation axis perpendicular to the deck. It is a self-protection and traction device for vehicles and ships. It can be used in snow, Self-rescue and rescue in harsh environments such as swamps, deserts, beaches, and muddy mountain roads, and under other conditions, can perform obstacle clearance, dragging items, installing facilities and other operations. It is military police, oil, hydrology, environmental protection, forestry, transportation , Public security, border defense, fire protection and other indispensable safety devices for outdoor sports. Mainly used in off-road vehicles, agricultural vehicles, ATV all-terrain vehicles, yachts, fire rescue vehicles, road wreckers and other special vehicles, special vehicles.

A winch is a hoisting device that is rotated by a human or a mechanical power to rotate a vertically-set drum and to wind a flexible member (wire rope, chain, etc.) horizontally to complete the traction operation. There are two types of manual winch and electric winch. Except for the drum part, there is no principle difference from ordinary hoists, and it is often used for handling work and ship terminals ^[1]

To put it simply, the working mechanism inside the winch is: the electric power from the car first drives the motor, and then the motor drives the drum, and the drum drives the driving shaft, which in turn drives the planetary gear, and then generates a powerful

1. The traction force of the winch is set in pounds, which can be converted into tons or kilograms through conversion. It's better to choose a high-pound winch, because the weight of the vehicle in trouble is often much higher than the daily weight of the vehicle. Do not tow objects that exceed the traction of the winch.

2. The more turns the steel cable of the winch is wound on the reel, the

1. According to the motive force of the winch, there are six types:

In short, the operation of the winch can be divided into three steps: installation, fixing of the fulcrum and dragging.

First, installation.

The use of a winch must of course begin with the installation. Although it is not complicated, it is the most important step because it is directly related to the subsequent steps and the use of the winch. The most important thing is to pay attention to the condition of the rope drum, and to ensure that the rope is evenly wound before starting and throughout the use. The specific installation process is as follows:

1. Insert the remote control. Insert the end of the remote control cable into the winch.

2. Do not let the remote control cable hang. The driver can operate the remote control in the driver's seat and wrap the extra wiring around the side mirror of the car, which will be much more convenient to work.

3. Open the noose, use the remote control to release the noose a little and then open the noose hook installed on the side of the winch.

4. Open the clutch. Be sure to open the clutch after opening the hook.

5. Hold the noose hook with your hand. When pulling the noose from the drum, hold the hook with one hand, no matter how long you pull the noose, you will not reach the hook.

6. After pulling the noose to the fulcrum, lock the clutch. The winch is ready.

Second, fixed fulcrum.

If you want to pull the car forward, there must be a safe place to fix the fulcrum, and the fulcrum must be able to bear the full weight of the car. The most basic principle is to pull directly in front of the car without angle. In off-road driving, the most commonly used fulcrum is the tree. However, if you use a winch to rescue another trapped vehicle, the rescue vehicle can also be used as a fulcrum, but you must block the wheels so that they cannot roll, that is, ensure that the rescue vehicle will not move.

No matter what kind of winch is used, its potential cannot be fully realized without a secure fulcrum. That said, fixing the fulcrum is a crucial step when using a winch.

When using a winch, a strap is also needed to connect the winch, fulcrum and noose hooks and u-shaped lifting ears. If the winch does not have enough power to drag a heavy object with a single wire, it needs to be strengthened with a double wire, and a tight-line pulley is also required.

It is also important to note that when using a tree as a fulcrum, use the widest part of the strap to prevent the strap from getting into the bark and destroy the trees. Be sure to tie the left and right ends of the strap to the sides of the ears respectively The straps should be the same length.

Third, drag.

The specific steps for dragging with a winch are:

1. Check the drum first. Before you start, make sure that the noose is neatly wrapped around the drum.

2. If the noose comes out, it should be prevented from flicking back and forth. If the noose breaks, the rope swaying back and forth can be very dangerous. However, you can avoid it, just put a pad on the tight noose.

3. Start dragging. If you use a noose to pull your car and you want to drive in the car, it is best to have someone outside the car to help you. The driver can operate the winch in the car according to the instructions of the commander outside the car.

4. If the noose is twisted together, be sure to pull it away. The noose crosses easily on the drum or becomes uneven on one side. Therefore, pay close attention to its status.

5. When the car is able to walk freely, the dragging is complete. Once back on the ground, check the condition of the vehicles and lines. If the car can be driven without external force, the process of dragging with a winch is over.

6. Roll the noose. Tighten the noose and carefully return it. If the noose crosses or twists on the drum, it must be fully untied before rewinding.

7, finally put the hook. When there is only one last point of the noose, tie the hook to the side of the winch. Then roll up the remaining noose and press the hook.

8. Remove the remote control.

Precautions:

1. It is best to ensure that the towing vehicle and the towed vehicle are in a straight line. The angle traction will offset the traction force, and the second will cause the steel cable of the winch to be wound at one end. If you cannot adjust the angle, you can use the directional pulley.

2. When using a winch to pull heavy objects or vehicles, always pay attention to the battery voltage. If the battery voltage is too low, stop the operation immediately and increase the battery speed by forcing the generator to charge by increasing the engine speed. Because the power of the winch motor is a fixed amount, the lower the voltage, the larger the current of the breakdown battery and the control relay. Forcibly using low voltage, it is easier to reduce the life of the battery and the relay in the control box faster. When the voltage is low, the rope winding speed will be slowed.

3. When dragging heavy objects or vehicles that are difficult to drag, you can use a pulley set to form a circuit and increase traction.

4. During the dragging process, a reasonable method should be used to fix the traction points, such as tire punching, fixing the vehicle body, and skilled use of tools such as tree bands and ground spears 5. Ensure the reliability of the clutch switch to avoid danger during rescue.

6. Wear gloves when operating the winch cable, and place rubber pads on the cable to place a destructive rebound after the winch cable breaks.

7. If the time is not tight enough to ensure the finishing of the rope, you need to re-release the rope fence and rewind the rope fence neatly on the reel if the conditions permit. Avoid long and messy rope fences.

8. When towing an object, if you need to loosen the steel cable, you should use the loose rope button carefully, which will easily cause the cable to be knotted and entangled on the reel. You can use the clutch to stretch the cable as straight as possible before using it.

9, the team travel, off-road, adventure is best equipped with 2 winches to deal with difficulties or dangerous situations.

10. The winch should be rigidly connected to the most solid and reliable place of the car body to avoid separation from the car body or other dangers when dragged.

11. A spare battery is needed. The thing is an electric tiger. The winch can quickly drain the battery. A double battery is necessary, and the second battery can be bigger.

The winch is often used under harsh conditions. Therefore, daily use will seriously affect its life. You must not overlook routine maintenance.

1. The inside of the winch is easy to enter the water, and it needs to be disassembled and maintained frequently (recommended 1 year / 1 time), replace the butter and check the gear.

The winch is really used on cars. Starting from Jeep in World War II, after the United States entered the war, on the open desert battlefield in North Africa, jeep cars often fell into sand pits or cannonball pits, plus jeep's bulky body, the rescue method was very laborious! Therefore, the US military began to apply winches to cars for self-rescue. The original car winch was a wire rope tied to the car body, and then it began to use the motor to have a real self-rescue function! At the end of World War II, the winch is highly sought after by off-road fans, and it is also one of the necessary tools for off-road vehicle modification!
