Different Kinds of Hoists and Their Functions

Different Kinds of Hoists and Their Functions

A hoist is a device that uses chains or cables to lift weights. Its mechanism allows for lifting heavy objects with relative ease. Hoists can be manual or automated, with a motorized or electrical chain hoist trolley attached at the top.

You’ve probably ridden one, as elevators are hoists. But hoists also play an important role in many industries, like construction and manufacturing.

If you’re looking to buy a hoist, it’s important to know the different types and what each is suited for. There are several different kinds of hoists on the market. Each has its strengths and weaknesses, so it’s important to pick the right one for your needs.

The Different Types of Hoists Here are the types of hoists by category:

•

By Power Source

1. Electric hoists. These types of hoists use electric motors for lifting. It is best suited for businesses that require heavy lifting but don’t have the workforce.

2. Manual hoists. Manual hoists use human power to work. Manual hoists are great for farmers, home mechanics, and small businesses. Because you operate them manually, you don’t need to worry about overheating or long breaks.

3. Pneumatic hoists. These hoists use compressed air as the motor’s power source. Their difference from electric hoists is that pneumatic hoists don’t overheat.

By Load Chain 1. Chain hoists. Manual hoists often use chains. They are easy to grip and more reliable than wire rope. Chains are very durable and last a long time.

However, they have a lift limit of 10 tonnes.

2. Wire ropes. Commonly used on pneumatic and electric hoists. These offer a large lifting capacity because of their high tensile strength. They can lift more than 10 tonnes. They also offer a faster and quieter operation than chain hoists.

By Mount 1. Trolley mounted hoists. These are hoists with an integrated chain hoist trolley. They are convenient because you can attach your trolley to the support beam and be ready to go.

2. Lug mounted hoists. This hoist uses a lug mounting bracket that attaches to the hoist frame. The hoist then connects to a trolley system or some other type of support system. Like hook-mounted hoists, these types of hoists are also popular.

3. Hook-mounted hoists. These are a hook attached to either a hoist trolley or a fixed position. This type of hoist has the simplest mounting configuration.
