A winch can be described as a mechanical object that is employed in regulating the tension in a (wire)cable. The device is used to pull in or let out (wind up or wind out).  A spool (or winch drum) is affixed to a hand crank in its simplest form. Winches present on ships are used to gather rope on the drum; capstans, on the other hand, don’t accumulate wire or rope on the drum and instead let it pass on.

Steam shovels, elevators and, tow trucks all use winches as part of their design. Gear assemblies are used in designs that are more complex, which can be driven by hydraulic, pneumatic, internal combustion, or electric engines. It could have a brake that is solenoid, a mechanical brake, or possibly, a ratchet and pawl system that prevents it from unwinding until the pawl retracts. 

The inclusion of a winch, that can be used to either extricate automobiles that have been incapacitated or load them onto a flatbed/tilt and tow trucks(load type), is the primary feature that legally differentiates a tow truck from a standard truck in many jurisdictions.

These are powered by a power take-off, then they are wound using a winch cable that has a hook. Snatch blocks can be used to change direction and/or enhance pulling strength, and several specialist hooks, including hooks that attach to certain parts of the vehicle, can be affixed to the main hook.

Types Of Winch

There are different types of winches that are existent in the market, we will examine a few of them in this section.

  1. Lever Winch – Many winches utilize spools/winch drum to move their rope, however, the lever winch uses self-gripping jaws rather than the drums. You will be able to easily move anything weighing about half a ton by cranking the lever winch with its handle. As a result, a lever winch is ideal for use on work sites or in activities that frequently involve big loads.
  2. Air Winch – Air winches, also known as power winches, are capable of lifting or suspending items. Air goes through the motor drive mechanism of the winch to make this sort of winch work, with condensation developing as a consequence. As a result, water may begin to drip from under the winch but it can be mitigated by installing big water screens and traps into the airplane. Oil foggers can also help to keep the internal parts of the engine from corroding or rusting. Air winches are more expensive than other types of winches, they also make loud noises. However, air winches are stronger and more powerful than the other types.
  3. Glider Winch – A glider must be hauled to speed by the use of a glider winch before it can take off. Winches like these are controlled from the rear ends of large trucks. Although electric or hydraulic systems may be offered, most glider winches run on LPG, gasoline, or diesel. The cables for this winch-type range in length from a thousand to 2,500 meters. Glider winches accelerate a plane until it lifts away from the ground and begins a fast climb. The lever is pulled to execute the launch when the glider achieves a height equal to 35 percent of the length of the cable.
  4. Capstan Winch – The vertical axis is the distinguishing feature of this winch type. Apart than that, it works in the same way as horizontal axle windlasses. On vessels, this revolving mechanism can draw, suspend, or apply pressure on masses. Sailors use capstan winches to reposition sails and other kinds of lines, and they’re designed to be put aboard ships.
  5. Wakeskate Winch – This style of winch is likely recognizable to watersports aficionados. Wakeskate winches typically feature a spool(winch drum), handles, an engine, and a rope. A person swims away from the winch or positions himself on the starting dock first. The winch then pulls the person over the water at about 24 to 40 km/hr. Wakeskate winches are able to be mounted on the rear of a boat, mounted on trees, or set in the ground with skates.
  6. Mooring Winch – This sort of winch is employed to keep a vessel in its berth by securing the shipboard end of the mooring line. It can also aid in adjusting the length of the mooring line, particularly when taking into account changes in draft and tide. The number of barrels used by mooring winches to haul in cables and ropes vary according to the size of the ship.
  7. Snubbing Winch – Snubbing winches, unlike other types of winches, have vertical spools and a traditional ratchet system, but no crank handles. They use tail lines to reel in their rope. Even with a small degree of operator tension, a snubbing winch can take loads after it is wound up or stopped. The roughness of the line that is around the winch drum can also be used to manage tension and pressure relief. This style of winch is ideal for adjusting the ropes on small boats and rowboats. For harder jobs, one of these devices could be used to assist a primary winch.

Other characteristics, such as the type of drive, can be used to classify winches (pneumatic, hydraulic winches, electric, or diesel winches). However, understanding these seven fundamental categories is helpful in picking the optimal winch to be used for a specific application. It’s also helpful to remember that winches differ from hoists in various ways, thus one cannot be used in place of another. Before making any purchases, you should get assistance from specialists who can assist you in selecting the proper sort of winch.

Doubling Winch Power

In doubling the pulling power of your winch, you can employ the use of snatch blocks in changing the angle from which to attack and multiply the degree of work the winch will be able in a given pull. By folding the layer of rope back on itself or putting an extra layer, you can double the pulling power of the winch while halving your winching speed. 

As the lines are folded back, your snatch block distributes the weight of the load being pulled. Using a single-line pull and hooking it back to the winching truck, for example, seemingly doubles the power or distributes the burden between the two lines. Depending on the kind of configuration, using two snatch blocks can cause the force to triple or quadruple. You can utilize as many blocks as you like for a pull as far as you don’t overload your weakest part of the gear. I’ll leave it up to you to figure out which parts aren’t designed to withstand the strain of the winch rope.

Snatch blocks can be used to apply huge force to a load, but be sure that each component is authorized for the maximum force that can be applied. If the cargo becomes too heavy to transport, you can violently and expensively remove the winch from the vehicle’s frame.


There are many different ways to double winch pulling power, however, we have looked at one of the most popular methods that are used, which is using multiple snatch blocks. There are many more alternative methods, like using pulley blocks or using a sturdy tree while applying a tree trunk protector.

The kind of winch to be used is dependent on the vehicle weight or the weight range of the object to be pulled. When a winch’s winching power is doubled, it can pull heavy loads that are up to twice its normal pulling power, as long as there’s a viable anchor.
