Engineering You
Can Verify.
Every Sanyo ISquare elevator is built on a European component backbone — names you can look up, certifications you can verify, and specifications that stand up to independent scrutiny. No ambiguity in what goes into your shaft.
The Technology Behind Every Lift
Six European manufacturers. Each selected for measurable quality advantages over regional alternatives. Each supplying verifiable product documentation.
WITTUR
Germany
Door Systems
DE-AIII and DE-AI automatic door operators. Modular cassette design reduces installation time by 30%. Fire-rated door assemblies tested to 120-minute (EI 120) resistance per EN81-58.
Sicor
Italy
Gearless Traction Machines
Permanent magnet synchronous motors with VVVF control. Compact, high-efficiency design eliminates machine room requirement. Noise level approximately 55 dB(A) — significantly quieter than geared alternatives.
Pfeifer Drako
Germany
IWRC Suspension Ropes
Independent Wire Rope Core (8×19 construction) provides superior fatigue life and load distribution. Traceable manufacturing certificates provided with every installation.
Monteferro
Italy
Guide Rails
T-section cold-drawn steel guide rails with precise dimensional tolerances. Reduces vibration and contributes directly to ride quality across the full travel height.
WECO / IRIS
Europe
Control Systems
Microprocessor-based group control with energy-saving features, floor-by-floor diagnostics, and remote monitoring capability. Supports destination dispatch and access control integration.
Ziehl-Abegg
Germany
Motors & Drives
VVVF drives with regenerative braking — energy recovered during descent is fed back to the building's electrical system, reducing net energy consumption by up to 30%.
Standards That Cannot Be Compromised
EN81 is not marketing terminology — it is a set of engineering requirements backed by third-party testing and certification. Here is what each standard means in practice.
Safety Rules for Elevators
EN81-20 covers safety rules for the construction and installation of lifts. EN81-50 defines examination rules for design principles, calculations, and examinations of lift components. Every Sanyo ISquare elevator is designed and installed to comply fully with both standards.
Fire-Rated Landing Doors
WITTUR fire-rated landing door assemblies are tested to 120-minute fire resistance per EN81-58:2018 (EI 120). This is mandatory under NBC fire codes for high-rise residential and commercial buildings — and is provided as standard on every Sanyo ISquare installation.
Safe Torque Off Technology
STO (Safe Torque Off) removes drive torque safely during an emergency stop without cutting main power to the drive. This enables faster, controlled resumption of service and is a key SIL-rated safety function in modern elevator drives.
Automatic Rescue Device
The ARD is a battery-powered unit that activates automatically when mains power is lost. It drives the elevator to the nearest floor landing, opens the doors, and keeps them open — eliminating passenger entrapment without any manual rescue operation.
Independent Wire Rope Core
Pfeifer Drako's 8×19 IWRC rope construction provides superior fatigue resistance and more even load distribution compared to fibre-core ropes. Manufacturing traceability certificates are provided with every installation — a verifiable quality chain from factory to shaft.
Gearless MRL vs Geared Machine Room
Understanding the difference helps you specify the right system for your project. For most South Indian mid-rise residential and commercial buildings, gearless MRL is the preferred choice.
| Parameter | Gearless MRL | Geared (MR) |
|---|---|---|
| Speed Range | 0.5 – 1.75 m/s | 0.5 – 1.0 m/s |
| Noise Level | ~55 dB(A) | 75 – 80 dB(A) |
| Energy Efficiency | High — regenerative drive | Moderate |
| Machine Room | Not required | Dedicated room required |
| Maintenance Interval | Quarterly | Monthly (gearbox oil, etc.) |
| Recommended Use | Residential, Commercial 5–20F | Heavy commercial, industrial |
Typical values for standard configurations. Final specification subject to project review.
