Have you ever been in a situation where you needed an extra hand? Like when your car is stuck in mud water.
Or, if you’ve ever been working on a project, simply to find you couldn’t complete it in a timely fashion because you didn’t have the manpower to do so, a winch might’ve come in handy for such projects.
Okay, so now that you’ve heard the term, what exactly is a winch? In its most basic definition, a winch is a mechanical instrument/tool which helps you wind up or wind out rope/cable, or suspend heavy objects.
It works similarly to a pulley mechanism, but isn’t simply limited to winding up/down rope. So, if you’ve ever been in a situation where you were working with heavy materials, lifting, pulling, or suspending items often, or simply didn’t have a large enough team in place to complete the job, you might appreciate how this neat tool can help you going forward.
How does the winch work?
Basically, a winch is pulled or rotated on a pulley mechanism system. The rotating element is turned internally by ropes, and they work as a crank to pull (lift, suspend) heavy items.
They are most often used to adjust tension levels with cables, but a winch can also be used for other projects/jobs which require heavy lifting as well. It operates using the spool and hand-crank system.
Most winches include the spool and crank system. You might’ve likely seen them in elevator systems, used as heavy-tow mechanisms as like it is used on a truck shock, or even on a steam truck, to help move heavy loads, without straining the employees performing different tasks in the workplace.
Which winch is right for your project or job? Types of winches used in commercial practice :
Okay, now that you know the basics of the winch, what type is right for you, and the type of job you plan on using the system for?
Let’s take a look at some of the most common types of winches used in jobs which require frequent lifting or suspension on a job-site.
The Snubbing Winch .
- This system works on a vertical spool and the ratchet system is similar to those of any conventional winch system. No crank handle is present, which differentiates this from a conventional winch system. A tail line is used to pull the rope back into the spool, and once fully pulled in, the winch takes loads with low tension levels. A controlled pressure relief is also achieved with this winch.
- A ratcheted spool operator is used for containing pressure. This along with the friction line helps with tension control. This winch is often used on small sailing boats, dinghies, or similar vessels. As this winch can’t control sheets or other line forms, they are limited in use to specific projects.
The Lever Winch
- This winch doesn’t use a spool, but rather self-gripping jaws. This jaw is also used to move the rope through the winch. Using a simple handle to crank the winch, you can easily move thousands of pounds. This is a great option for construction sites, or jobs where you are moving heavy loads frequently.
The Air Winch
- This is often called an air hoist (or an air tugger); it is basically an air-powered winch. It can be used to lift materials, or to suspend materials in the air. In comparison to hydraulic, diesel, or electric winches, the air-pressured winch is more durable and can lift heavier loads. Major companies, doing large-scale construction or development work, typically rely on this winch system.
The Capstan Winch
This winch is known as a “vertical-axis” winch. It is specifically designed for use on sailing ships, and is a rotating device which helps pull/suspend weight on vessels. It is basically used by sailors to apply pressure to, and suspend sails, cables, and ropes on deck.
The Glider Winch
- As the name implies, this is used for launching a glider/plane. They are fitted to heavy trailers/vehicles, and they are operated by petroleum, LPG, or diesel fuel. Electric and hydraulic varieties are also available, but not as widely used.
- The cable is used to pull anywhere from 1000 to 1600-meter cables, which are attached to the glider. This is pulled up a steep climb, and the lever is then released once a distance of 400-700-meters has been reached.
Other varieties such as mooring, and wake-stake winches are also used, but not as often as those mentioned above.
Of course depending on the job, different winches are better suited for use than others, so it is important to understand how they work, prior to investing in one, or renting one, for your next major commercial project.
Verdict: Do you need a winch?
Although the answer is no (in theory), in practice, it is well-worth the investment if you are doing heavy-lifting jobs, or work which requires frequent lifting or movement of heavy objects on a job site.
Due to the simplicity of the system, winches are seen on various job sites. Construction sites, railroad/airline jobs, or other projects which require suspension or heavy-lifting to be performed regularly.
