Rigorous Testing & Commissioning

Noman Elevators delivers Rigorous Testing & Commissioning with Sharif Mill precision.

Testing ensures every elevator achieves 95% uptime from Day 1. Our 17 Raheem Road technicians execute comprehensive validation before handover, meeting EN81-20 standards and Pakistani building codes.

Mechanical Performance Tests

Pre-Test Controller Setup

Elevator placed in normal automatic operation (not inspection mode).CAN-bus controller diagnostics confirm zero faults. All safety chains verified closed (doors, limits, buffers). VVVF drive parameters loaded: 1.75m/s max speed, jerk ≤1.5m/s³.

Cycle Initiation (Cycle 1-25)

Technician registers car calls to all floors simultaneously. Elevator executes full journey: lowest floor → highest floor → repeat. Digital logger records: speed profile, acceleration curves, settling times. Each floor stop verifies ±5mm leveling accuracy.

Door Operation Validation (Cycles 26-50)

Door open/close timing measured against EN81-20 limits: Open time: ≤12 seconds (450kg cab) Close time: ≤10 seconds Nudging operation tested (3-second pressure override). Photoelectric sensors confirmed unobstructed across 100 door cycles.

Ride Comfort Analysis (Cycles 51-75)

Vibration monitoring (<0.1g RMS) using triaxial accelerometer: Motor room vibration envelope Cab floor vibration signature Guide shoe/shoe bracket interface Jerk measurement peaks never exceed 1.5m/s³ during acceleration/deceleration.

Emergency Stop Verification (Cycles 76-100)

Random floor emergency stop button activation during travel: Response time ≤1.5 seconds to full stop Re-leveling accuracy ±10mm after reset 5 consecutive stops per floor, staggered randomly Brake holding force confirmed across full speed range.

Data Analysis & Reporting

Controller downloads 100-cycle performance log: 15,000+ data points analyzed (speed, jerk, leveling, vibration) Pass criteria: 98% cycles within specs CAN-bus fault log reviewed (must show zero repeat faults) Digital certificate generated for client handover.

Noman Elevators: Precision Elevator Construction Excellence

Elevator construction requires engineering precision beyond ordinary building work. Noman Elevators delivers turnkey installations from 17 Raheem Road that achieve 95% uptime through Sharif Mill-certified processes.

Advanced Engineering Planning

Shaft & Pit Engineering

Laser-precise measurements create 1500x1500mm shafts, 1400mm pits, T-9 rail alignments (1:1000 tolerance). VVVF motor layouts optimize 20kW power distribution. SS304 cab designs maximize light/noise isolation.

Load & Speed Optimization

450kg residential (1.75m/s), 1000kg commercial (1.5m/s), 1600kg hospital (1.0m/s) - each capacity engineered for Lahore high-rise demands. CAN-bus controls enable duplex/triplex group operation.

Code Compliance Matrix

EN81-20 safety, Pakistani Building Code seismic, Phase I/II fire service - every drawing stamped by Sharif Mill engineers before fabrication begins.

Quality Control & Installation Oversight

Noman Elevators maintains absolute precision throughout construction with multi-layer verification systems.

Frequently Asked Questions

What's included in 8-12 week timeline?

Laser survey → engineering drawings → FAT-tested delivery → rail alignment → 100-cycle testing → client training.

Hospital lift requirements?

1600kg stretcher cabs (1100x2100mm), ARD power failure rescue, 0.63m/s smooth operation, Phase I/II fire recall.

Can you modify existing buildings?

Yes - machine room conversions, shaft enlargements (1500x1500mm min), pit deepening (1400mm).

Warranty coverage details?

24-months full coverage, 95% uptime guarantee, 2-hour Misri Shah response, quarterly inspections included.

VVVF vs hydraulic comparison?

VVVF = 30% energy savings, 1.75m/s speed, smooth ride. Hydraulic = low-rise freight, slower (0.63m/s).
