An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six cla ...

Chutes are in common use in tall buildings to allow the rapid transport of items from the upper floors to a central location on one of the lower floors or basement. Chutes may be round, square or rectangular at the top and/or the bottom.

: Home laundry chutes are placed on each floor of multistory
homes allow the collection of all household members' dirty laundry to one location, conveniently next to the laundry facilities, without the constant transport of laundry bins from story-to-story or room-to-room or up and down stairs. Home laundry chutes may be less common than previously due to building codes or concern regarding
fireblocking, the prevention of fire from spreading from floor-to-floor, as well as child safety. However, construction including cabinets, doors, lids, and
locks may make both risks significantly less than with simple
stairwells.
* Refuse chute or Garbage chutes are common in high-rise
apartment buildings and are used to collect all the building's garbage in one place. Often the bottom end of the chute is placed directly above a large, open
waste container. This makes
garbage collection faster and more efficient.

Mail chutes are used in some buildings to collect the occupants' mail. A notable example is the
Asia Insurance Building.
*
Escape chutes are used and proposed for use in evacuation of mining equipment and high-rise buildings.
* Construction chutes are used to remove
rubble and similar demolition materials safely from taller buildings. These temporary structures typically consist of a chain of cylindrical or conical plastic tubes, each fitted into the top of the one below and tied together, usually with

skip or other receptacle, and waste materials are dropped into the top. Heavy duty steel chutes may also be used when the debris being deposited is heavy duty and in cases of particularly high buildings.
