Passenger Elevator with 304 Hairline Stainless Steel Cabin
Traction-driven elevator system with SUS304 stainless steel cabin panels (thickness 0.8–1.5 mm). Surface finish is hairline type with Ra 0.2–0.5 μm. System configured for mid- to high-rise buildings with traffic density ≥300 persons/hour and door cycles up to 100,000/year.
Technical Data
| Parameter | Value | Engineering Note |
|---|---|---|
| Rated Load | 630–1600 kg | 8–21 persons per trip |
| Speed | 0.5–1.75 m/s | <60m: ≤1.0 m/s typical |
| Door Width | 800–1100 mm | Hospital ≥900 mm |
| Door Height | 2000–2100 mm | Standard clearance |
| Shaft Width | 1600–2500 mm | Depends on load |
| Travel Height | ≤120 m | Gearless recommended >60m |
Application Scenarios
Hospital: cleaning frequency ≥5 cycles/day using alcohol-based agents; requires stainless steel corrosion resistance and easy surface maintenance.
Mall: door cycles ≥100,000/year; requires door operator durability and stable opening speed control.
Residential: traffic peaks during morning/evening; speed typically ≤1.75 m/s with energy-saving standby mode.
Failure → Engineering Control
Rope slip → Increase wrap angle ≥180°, maintain groove friction coefficient 0.08–0.12.
Leveling error → Encoder resolution ≥1024 ppr + VFD closed-loop control (±5 mm).
Door obstruction → Infrared curtain detection + closing force ≤150 N.
Brake wear → Dual electromagnetic brake, gap ≤0.3 mm, response time ≤0.2 s.
Panel deformation → Use ≥1.2 mm thickness for high traffic (>500 cycles/day).
Configuration Selection Guide
Load selection: 630 kg for residential (<6 floors), 1000–1600 kg for commercial buildings.
Motor type: Gearless for speed ≥1.0 m/s or travel height >60 m.
Panel thickness: 0.8 mm (<200 cycles/day), 1.2–1.5 mm (>500 cycles/day).
Material: SUS304 for indoor humidity >70%, SUS316 for chloride exposure environments.
Material Comparison
SUS201: Ni content ~1–2%, lower corrosion resistance, used in dry indoor environments.
SUS304: Ni content ~8%, balanced corrosion resistance for commercial buildings.
SUS316: Mo content 2–3%, improved resistance to chloride corrosion, used in coastal or chemical environments.
Engineering FAQ
Can SUS304 be used in coastal areas?
Only if chloride ion concentration <50 ppm; otherwise use SUS316.
How to select panel thickness?
Based on door cycles: <200/day → 0.8 mm; >500/day → ≥1.2 mm.
What is typical maintenance interval?
Rope inspection every 6 months; brake and door system every 3 months.
