Viscosity: Hydraulic elevator fluids typically range from ISO VG 32 to ISO VG 68, depending on system requirements.

Buoyancy: Not applicable to most elevator systems, except for hydraulic elevators where fluid displacement is considered.

Material: Components include steel for cables and frames, aluminum or stainless steel for doors, and polyurethane or rubber for buffers and seals.

Safety Features: Includes emergency brakes, overspeed governors, door interlocks, and backup power systems.

Access: Standardized control panels, key-operated switches, and RFID/card-based access systems for restricted floors.

Maintenance: Requires regular lubrication, alignment checks, and inspection of mechanical and electrical components.
