A hoist is a suspended machinery unit that is used for lifting or lowering a freely suspended (unguided) load.Today, hoists find immense use in industry and engineering They may be manually operated, electrically operated or pneumatically driven and may use chain or wire rope as its lifting medium. The load is attached to the hoist by means of a lifting hook. While devices for lifting and transporting objects have been used for thousands of years, the invention of the hoist is commonly credited to the Greek inventor Archimedes.A hoist is usually operable only in the vertical dimension. However, it can be moved side ways as well. For this purpose, it is necessary to mount a hoist on a crossbeam. Such hoists are typically seen at warehouses and yards where heavy goods need to be lifted and moved from one place to another.Originally, hoists were operated manually. This was done with help of pulley or block and tackle systems. However, with the development of engines, hoists now use a motor for power. iServe Inc., offers high quality hoists which are designed according to the specific requirements of clients.

Electric hoists use electric power to lift and lower objects.Electric chain hoists are the most sought after lifting mechanism in various industries due to the increased productivity and efficiency they offer. In a market crowded with chain hoists, electric chain hoists are now amongst the most prominent. A variety of chain hoists are available these days. Since the days the first electric chain hoist was made, better and more reliable hoists have made their way on the market presently. These are extremely heavy-duty electrically powered devices that are specifically designed for lifting very heavy objects, typically above a ton. They will therefore be found on large scale project sites such as industrial sites or construction site. There are chiefly two types of electrical hoists – electric rope hoists and electric chain hoists

A chain hoist is a mechanical device used for lifting heavy loads of objects and equipment. It is made with a pulley, which is held together by a closed chain. The closed chain in the chain hoist forms a loop, which makes it easy to be pulled by hand.There are three types of chain hoists: air, manual, and electric. The manual chain hoist and the air chain hoist are designed with reduction gears, hook pivots, and swivels. Suspended by a top hook, or by a push or geared trolley, these types of chain hoists move objects slowly and carefully while making height adjustments.An air chain hoist is a pneumatically driven machinery unit that utilizes a chain as its lifting medium, and is used for the lifting and lowering of a freely suspended (unguided) load. Air chain hoists are often used in environments that require electric spark avoidance due to a potentially explosive atmosphere.The attached load is well secured so it can be left fixed without requiring a great deal of supervision. The electric chain hoist, on the other hand, is generally used for lifting heavy-duty industrial loads.The electric chain hoist allows the user to pull from the side as well as vertically.

Rope hoists use the mechanism of pulleys and sheaves with strong wire rope or fiber rope. They are mechanical devices that save both time and money while carrying goods. This type of hoists well suits for small and medium size jobs. By using rope hoists you can avoid tugging and lifting of the things. Use rope hoist and save yourself from hassles. They offer exceptional performance, easy load handling, superior safety, improved ergonomics and favorable dimensions. For industrial cranes, solo hoist or monorail applications, or for upgrading existing hoisting equipment,wire rope hoists offer the best return on your investment.If you are searching for any hoists that work for long duration of time then rope hoist is the suitable option. It is durable and available at affordable price. You can purchase based on your size and type requirement. With the help of rope hoist you can balance the material in any direction.
