Drum and counterweight home elevators are also cheap in comparison to pneumatic and hydraulic systems and are easy to install in small spaces.
>>>Roped hydraulic home elevatorsCombining the benefits of both hydraulic systems and the roped systems, roped hydraulic home elevators work on the basis of a hydraulic pump. This pump is connected to a pulley.
>>>lt;em>Pneumatic elevators: Also known as PVE, pneumatic vacuum elevators are the latest innovations in elevator technology. These elevators use a vacuum system and do not require counterweights, pistons, chains, and cables.
>>>These include hydraulic, pneumatic/air, and electric. The lifting speeds of powered hoists are quick. Moreover, these hoists have a broader range of lifting capacity and are operated by a controller or pendant.
>>>As an added bonus, modern designs are energy efficient and feature unique pneumatic and hydraulic drive systems to power the elevator cab. 
>>>This helped them to become the leaders in pneumatic tire manufacturers in Europe. Legislations were brought out to prevent the use of solid tires on highways as they were hard on the roads.
