Lawv tau dav siv nyob rau hauv siab - chaw tsheb thauj mus los xws li chaw nres tsheb ciav hlau, ferry terminals, khw malls, tshav dav hlau, thiab subway systems. Nyob rau hauv 1900, ib tug stepped tsiv staircase nthuav tawm ntawm Paris International Exposition tau ua tus qauv rau cov escalator niaj hnub. Tom qab ntawd, escalators underwent kev loj hlob sai thoob plaws ntiaj teb.
Cov yam ntxwv tseem ceeb ntawm tus escalator muaj xws li:
1. Lifting Qhov siab: Feem ntau nyob rau hauv 10 meters, txawm hais tias nyob rau hauv tshwj xeeb, nws muaj peev xwm ncav cuag li ob peb kaum meters.
2. Lub kaum sab xis: Feem ntau 30℃lossis 35℃.
3. Ceev: Feem ntau 0.5 meters ib ob; Qee cov qauv tuaj yeem ncav cuag qhov nrawm ntawm 0.65 meters ib ob lossis 0.75 meters ib ob.
4. Kauj Ruam Dav: 600 mm, 800 mm, lossis 1000 mm.
5. Theoretical Conveying Capacity: Raws li qhov ceev ntawm 0.5 meters ib ob, lub peev xwm conveying rau cov kauj ruam sib txawv yog 4,500 tus neeg / teev, 6,750 tus neeg / teev, thiab 9,000 tus neeg / teev, raws li.
6. Kauj Ruam Pitch, Traction Chain Pitch, thiab lwm yam kev qhia tshwj xeeb.
