A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.
The basic hoist has two important characteristics to define it: Lifting medium and power type. The lifting medium is either wire rope, wrapped around a drum, or load-chain, raised by a pulley with a special profile to engage the chain. The power can be provided by different means. Common means are hydraulics, electrical and air driven motors. Both the wire rope hoist and chain hoist have been in common use since the 1800s, however mass production of an Electric Hoist did not start until the early 1900s and was first adapted by Germany. A hoist can be built as one integral-package unit, designed for cost-effective purchasing and moderate use, or it can be built as a built-up custom unit, designed for durability and performance. The built-up hoist will be much more expensive, but will also be easier to repair and more durable. Package units were once regarded as being designed for light to moderate usage, but since the 60s this has changed. Built-up units are designed for heavy to severe service, but over the years that market has decreased in size since the advent of the more durable packaged hoist. A machine shop or fabricating shop will use an integral-package hoist, while a Steel Mill or NASA would use a built-up unit to meet durability, performance, and repairability requirements. NASA has also seen a change in the use of package hoists. The NASA Astronaut training pool, for example, utilizes cranes with packaged hoists.

FAQ:
1. Are you a manufacturer or a trading company?
We are a professional manufacturer with over 15 years' export experience for designing and producing vehicle machinery parts.
2. How can I get some samples?
If you need, we are glad to offer you samples for free, but the new clients are expected to pay the courier cost,
and the charge will be deducted from the payment for formal order.
3. Can you make casting according to our drawing?
Yes, we can make casting according to your drawing, 2D drawing, or 3D cad model. If the 3D cad model can be supplied,
the development of the tooling can be more efficient. But without 3D, based on 2D drawing we can still make the samples properly approved.
4. Can you make casting based on our samples?
Yes, we can make measurement based on your samples to make drawings for tooling making.
5. What's your quality control device in house?
We have spectrometer in house to monitor the chemical property, tensile test machine to control the mechanical property and UT Sonic as NDT checking method to control the casting detect under the surface of casting.
