Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, air conditioning and transportation (elevators and escalators) around a building. [1] It is a tool that helps analyze complex systems.
Stiltz elevators run on freestanding, self-supporting rails, so they don’t need supporting walls or elevator shafts. However, the compact design means the Duo Classic model can’t accommodate ...
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 ...
A paternoster in Prague Paternoster elevator in The Hague, when it was still in operation. A paternoster (/ ˌ p eɪ t ər ˈ n ɒ s t ər /, / ˌ p ɑː-/, or / ˌ p æ-/) or paternoster lift is a passenger elevator which consists of a chain of open compartments (each usually designed for two people) that move slowly in a loop up and down inside a building without stopping.
File talk:World Trade Center Building Design with Floor and Elevator Arrangment.svg Metadata This file contains additional information, probably added from the digital camera or scanner used to create or digitize it.
This layout is usually reflected in the internal elevator zoning. Since nearly all elevators require machine rooms above the last floor they service, mechanical floors are often used to divide shafts that are stacked on top of each other to save space. A transfer level or skylobby is sometimes placed just below those floors.
Physical factors such as the distance to be spanned determine the length and pitch of the escalator, while factors such as the infrastructure's ability to provide support and power must be considered. How upward and downward traffic is separated and load/unload areas are other important considerations. Temporal traffic patterns must be anticipated.
