A pneumatic hoist is a lifting device that uses compressed air to raise and lower heavy objects. It is commonly used in industrial settings where heavy loads need to be moved safely and efficiently. The hoist operates by converting air pressure into mechanical energy, allowing it to lift items with ease. These hoists are often preferred for their lightweight design and ability to work in hazardous environments, as they do not produce sparks like electric hoists. They are ideal for tasks in places like warehouses, construction sites, and manufacturing plants, making them a versatile tool for various lifting needs.
