About Aston

Built on engineering discipline, not trading.

Aston is focused on one core system: gearless traction. Every machine is selected, configured, and tested against defined specifications before it ships.

Our machines are developed through established manufacturing partners in Asia, built to defined specifications, and controlled under consistent quality benchmarks. Each unit is configured for the load profile it serves and tested before release.

Today, we ship a focused product line — the WTD2-P permanent magnet gearless platform — engineered to deliver three things: stable performance across the operating envelope, low vibration and noise in real installations, and long operational life under continuous duty.

We are building toward localized manufacturing in India, with the goal of delivering globally competitive traction systems with tighter control over quality, lead time, and cost — and a stronger platform to serve the next decade of regional infrastructure.

Engineering focus

Traction systems designed for real-world elevator duty cycles, not catalog specifications.

Controlled sourcing

Manufactured through vetted facilities with defined quality standards and inspection protocols.

Scalable platform

Architecture built to expand into full elevator drive systems and controls.

Product

Gearless traction machine.

A focused product line built around a single permanent magnet gearless platform — engineered for residential and small commercial elevator applications, available in two configurations.

Engineering

Designed for performance and longevity.

Every Aston traction system is built around four operating principles: efficiency, thermal stability, acoustic control, and mechanical reliability under continuous duty.

Permanent magnet architecture

NdFeB magnetic poles deliver high efficiency with reduced energy consumption and improved torque characteristics across the operating range.

Precision sheave design

Optimized groove geometry for rope life and traction stability under varied load and acceleration profiles.

Thermal management

Designed to maintain performance under continuous duty cycles, with Class F insulation rated for tropical service conditions.

Low-noise operation

Engineered for smooth rotation and reduced vibration in real installations, supporting acoustic targets in occupied buildings.

Global Presence

Built globally. Expanding locally.

Aston operates through a global supply chain with manufacturing partners in Asia, ensuring consistent product availability and competitive pricing. Our next phase establishes manufacturing capability in India.
