See The 6 Best Chain Hoists on Ezvid Wiki ►► [ Ссылка ]
Fact #1. The chain hoist was first developed around the time of the Great Depression. In the beginning it was mostly used by utility companies and equipment manufacturers. It quickly expanded into other industries. In the late 1930s, John Deere gave it their stamp of approval for farm work. By the time the 1940s rolled around, one could be found on nearly every farm across America
Fact #2. Chain hoists can be used to lift nearly any type of heavy load, but are commonly found in mechanic shops, factories, and warehouses. They're available in manual and electrical varieties. Electric units often feature some kind of controller. Lifting a heavy object with one is as simple as pushing a button. Manual units require the operator to lift heavy objects by pulling on the chain.
Fact #3. A manual chain hoist is the simplest type of hoist. There's very little chance of one failing or malfunctioning. Every manual model contains a lifting chain with a hook, a hand chain, and a lifting mechanism. The lifting mechanism is made up of sprockets, an axle, a cog, a driveshaft and some gears.
Fact #4. Before attaching a load to a hoist, inspect the equipment to make sure everything is in good working order. Check that it's safely secured to a sturdy mounting point which is capable of supporting the full weight of the object you plan on lifting. Also inspect the chain for any overly rusted links, which can become break points when under load.
Fact #5. Start with a light load before lifting heavier objects. This will help you double check that all of the gears inside of the hoist are running smoothly and functioning as they should. You should lift the light load up, and then leave it suspended in the air to ensure the brake is working. Make sure you're using a hoist capable of lifting the weight by checking the manufacturer specifications.
