Premium Gearless Traction Elevators in Pakistan

Blog Article


  1. Introduction


As Pakistan embraces an era of modern high-rises and commercial complexes, the demand for gearless traction electric elevators is rising. These advanced systems offer superior performance, energy efficiency, and passenger comfort ideal for tall buildings and high-traffic environments. Liberty Elevators is your local expert in delivering tailored gearless elevator solutions that align with Pakistan’s architectural and urban demands.

  1. What Are Gearless Traction Elevators?


Gearless traction elevators use a permanent magnet synchronous motor (PMSM) directly connected to the traction sheave eliminating mechanical gearboxes. This direct-drive design achieves smoother, quieter operation, higher speed, and greater energy efficiency.

  1. Advantages of Gearless Technology



  • Minimal mechanical wear due to absence of gear mechanisms bearings are the primary wear points.

  • Energy savings: Up to ~40% lower power use than geared elevators e.g., a geared system (1,000 kg, 1 m/s) draws 11 kW, while a gearless variant uses only 6.7 kW.

  • Ultra-smooth and silent ideal for premium environments like hotels and offices.

  • Compact footprint: Often MRL (machine-room-less), requiring only shaft space.

  • Simplified maintenance: No gearbox oil, fewer components, longer intervals between inspections.

  • Durable and clean: No oil leakage, minimal pollution, flexible mounting.



  1. How Gearless Traction Works



  • Truly direct drive: A PMSM motor fixes the traction sheave integration, resulting in low-RPM, high-torque operation.

  • Traction sheave and ropes create necessary friction for car movement .

  • Passenger counterweight balances load, optimizing motor effort.

  • Precision control systems (VVVF + PLC) manage smooth starts, leveling, braking, and diagnostics.



  1. Suitability in Pakistan’s Context



  • Skyline architecture: Perfect for high-rise towers, corporate headquarters, hotels, and hospitals.

  • Growing demand: Cities like Karachi, Lahore, and Islamabad require elevator systems with greater efficiency and less mechanical space.

  • Evolving building codes emphasize energy efficiency and high safety standards.



  1. Global & Regional Adoption


International examples Burj Khalifa, Shanghai Tower, One World Trade Center—showcase gearless lifts in premium buildings.
Regionally, brands like KÖHLER offer compact gearless systems (e.g., SMR 1000) ideal for mid-rise MRL installations.
Local vendors such as PakLifts stock gearless machines from Turkey, Italy, China, supported nationwide.

  1. Drawbacks & Considerations



  • Higher upfront cost compared to geared or hydraulic systems.

  • Precise installation needed shaft overhead/pit clearance and structural support must be well-engineered.

  • Specialist maintenance: Requires technicians skilled in PMSM and VVVF systems.

  • Premium components like encoders and strong brakes add to cost.

  1. Designing & Installing Gearless Elevators



  1. Feasibility analysis: Assess building height, traffic, shaft dimensions.

  2. Technical specification: Select motor power, sheave size, VVVF drive, safety brakes.

  3. Shaft & support planning: Ensure overhead and pit clearances align with load.

  4. Component procurement: Import or source from Turkey, Italy, China via local suppliers.

  5. Installation: Precision mounting, alignment, control commissioning.

  6. Testing & compliance: Leveling accuracy, speed tests, brake/safety certifications.

  7. Training: Equip building staff for operations and maintenance with relevant documentation.

  8. AMC deployment: Schedule proactive maintenance, diagnostics, drive tuning.



  1. Maintenance & Lifecycle



  • Scheduled inspections: Bearings, ropes, sheave alignment, encoder calibration.

  • Drive maintenance: VVVF diagnostic checks, firmware updates.

  • Braking systems: Regular load tests and brake pad checks.

  • Safety systems: Overspeed governor and ARD function tests.

  • Periodic modernization: Component upgrades to extend system life and performance.



  1. ROI & Long-Term Benefits


While initial investment is higher, energy savings and reduced maintenance deliver compelling ROI within 5–7 years.
Adds premium value to high-end properties while reducing mechanical footprint.
Sustainable operation supports green building certifications and reduced carbon footprint.
