Chain Hoist Types
The ancient system of lifting objects with a pulley continues to be used even in today's high tech world. Pulleys are applied in many different ways and don't always just move objects upward. Sometimes they move them horizontally and sometimes pulleys actually power other machines like some conveyor rollers. In the case of hoists, pulleys come into use lifting heavy objects. Hoists also have a long history. The chain hoist, for example, has been around since the nineteenth century. This article will discuss the various chain hoist types available in the modern world and their applications.
A chain hoist is a type of pulley system designed to manage heavier loads. In a typical hoist, a chain is wrapped around a drum or wheel and a hook is used on the end to hold the object being lifted. Chain hoist types include manual, electric, and pneumatic. Warehouses and shipping companies are especially common users of hoists. These large operations take a lot of money to run and one of the best ways to save money is to cut down on employees. Developing better and more effective hoists has done a lot to help in that department.
Manual hoists. Manual hoists require a pair of hands and use a hook or geared trolley to lift loads. A hand chain hoist would have been common before electric and other forms of power (steam for example) were widely available. For instance, hundreds of years ago you would have seen manual hoists, or winders, powered by humans, animals, and water, used to haul supplies in and out of underground mines. Today, however, powered chain hoist types are prevalent and help to decrease the cost of labor and increase efficiency. Not to mention, motorized hoists can handle much heavier loads.
Electric hoists. Electric chain hoists are probably the most common of chain host types. Electric hoists eliminate the need for many employees, requiring one operator in most cases. This allows the money that would go to employee salaries and benefits to be put to use elsewhere. Electric motors can pack a lot of power and be used with a more Industrial Hoist such as construction hoists. These hoists, also called man-lifts and buckhoists, are often used in construction of high-rise buildings. They are essentially elevators that can carry workers and equipment from the ground to the top floor quickly and efficiently.
Pneumatic hoists. A pneumatic hoist, or a hoist powered by air, shares similarities with manual hoists. These chain hoist types also use a hook or geared trolley to lift their loads. To keep everything secure, they move slowly, making height adjustments as they go along. The good thing about this type of hoist is that it is good and stable so it doesn't need a lot of watching over as it does its job.
As we can see, chain hoist types are in abundance and find many applications. From the more primitive manual hoist to the modern electric powered chain hoist like a Yale hoist, this rather old invention can move basic objects and even people. Save money and time and invest in a chain hoist.
