What’s the Difference Between a Hoist and a Winch?
A wide range of industries use hoists and winches for many different applications. Even though these two pieces of equipment can look quite similar to the untrained eye, they are actually designed for very different purposes.
In short, hoists are designed to lift a load vertically over an incline greater than 45 degrees, while winches pull an object or load horizontally, usually over a flat surface or slight incline. Some products on the market can serve both hoisting and winching functions, meeting the needs of demanding environments where extra flexibility is required.
In this article, we’ll take a look at how hoists and winches work, the functions they serve and the main differences between them.
Hoists Lift the Load
A hoist is used to lift items vertically – either with manual or powered operation. Using a manual chain hoist, the operator will pull down one end of a chain, which then turns a pulley mechanism located inside the housing and raises the other end of the chain.
Powered hoists work in much the same way but instead use electric, air or hydraulic power to lift the load. Powered hoists are faster and capable of listing very heavy loads up to a maximum of around 25t SWL, making them well suited to heavy-duty applications.
The best type of hoist for a specific application will depend on many different factors including the maximum load to be lifted, the lifting height and required speed of operation. Many hoists incorporate options designed for particular use cases, like twin lifting hooks, or integral trolleys designed specifically for curved beams.
It’s also important to think carefully about the operating environment. For example, electric hoists are great for many applications, with capacities ranging from 125 kgs to 6,500 kgs, but may be unsuitable for hazardous environments due to a possible fire risk. In this case, an air powered or hydraulic hoist would be a suitable alternative and can operate with up to a 100% duty cycle. Some hoists are also specifically designed for particular industries, like pharmaceutical or production environments.
Winches Pull the Load
While hoists are made for lifting, winches are specifically engineered to pull objects in a horizontal direction, usually over a fairly flat surface or moderate incline.
As with hoists, there are both manual and powered winches available depending on the application, using electricity, air power or hydraulics to safely and efficiently pull the load.
Typically, a winch works by using the tension in a cable or rope to move the item. In powered versions, a motor turns the built-in drum and pulls the cable.
You will find a huge variety of winches available on the market, including a choice of numerous load capacities and different mounting options, including tripod, base and wall mounted models.
Some winches are also specially designed for heavy duty applications and/or potentially hazardous environments. For example, air wire rope winches may offer up to a 100% duty cycle and can be started an unlimited number of times, meaning they can be used all day every day without any issues.
Hoist or Winch?
Ultimately, the choice between a hoist and a winch will depend on why, how and where the customer is using it. Buyers should carefully think about their requirements and look at individual specifications to determine the best product for their needs.
