Hoist atop an elevator. 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.
Elevator In traction (non-hydraulic) elevators, a heavy counterweight counterbalances the load of the elevator carriage, so the motor lifts much less of the carriage's weight (specifically, the counterweight is the weight of the carriage plus 40-50% of its rated capacity). The counterweight also increases the ascending acceleration force and ...
The bucket elevator is the enabling technology that permitted the construction of grain elevators. A diverter at the top of the elevator allows the grain to be sent to the chosen bin. A similar device with flat steps is occasionally used as an elevator for humans, e.g. for employees in parking garages.

A residential elevator with integrated hoistway construction and machine-room-less design. A residential elevator or home lift is often permitted to be of lower cost and complexity than full commercial elevators. They may have unique design characteristics suited for home furnishings, such as hinged wooden shaft-access doors rather than the ...
Although this approach shifts the construction complexity away from the use of climbers in the cable seeding design, it increases the complexity of the required in-space infrastructure. The cable seeding design could be rendered infeasible in case the material strength is considerably lower than was projected by Brad Edwards. [2]
Inclined elevator design is based on the same basic technology as conventional, vertical elevator. [6] In general standard elevator equipment can be adapted for systems with an inclines up 10 ° from vertical, while an incline with more than 20° from vertical will require some additional adaptation.
