Chain Hoists Types And Uses

Chain hoists, which are used in many different industries, work on a pulley system. This system is hooked together by a closed chain and allows the hoist to lift very heavy items. The hoist is put together in two sections. The top of the hoist has a large pulley and a smaller pulley that are joined together side by side utilizing an axle. This top pulley system works together as one unit, allowing for durability and the ability to handle a good amount of weight. The system that is on the bottom is another pulley. This pulley is movable and is the section that is actually attached to the item that is being lifted. This type is used for many reasons, including that of an engine hoist.

A chain hoist is available in three different types. There are the electric hoists, the manual hoists and the air hoists. The electric hoists are used for more industrial purposes. They have the ability to lift extremely large loads and give the person using the hoist the ability to move it vertically and horizontally. This is not true of either the manual or the air hoists. These two types also move loads much slower than electric hoists, but are able to make adjustments to the height of the load.

Chain hoists are by no means the only hoists that utilize a pulley system. Rope hoists have long been used for many purposes, and one of the first that worked on a pulley system was used for raising objects up and down by hand. An example of this is the fixed pulley system that was used to draw water from wells. The pulley was affixed to the well and a rope was run through the pulley. The bucket was then secured to the rope and lowered into the well to draw up the water. Because this system allowed for too much friction between the rope and the pulley, it did not work extremely well. However, it did serve its purpose in showing that a pulley system had great potential where hoists were concerned.

Chain hoists have many different uses, one of them being an engine hoist, lifting heavy car and truck engines in and out of vehicles. But there are so many more uses for these hoist systems, all depending on what type of item needs to be raised and lowered and what industry is using the equipment hoists.
