High-Efficiency Gearless MRL Lifts

Premium Grade European Standard Lifetime Support

Experience unparalleled quality and innovation in elevator technology, designed for discerning clients who demand excellence in every detail.

Permanent Magnet Traction Engineering

High-efficiency gearless MRL (Machine-Room-Less) lifts utilize Permanent Magnet Synchronous Motor (PMSM) technology to achieve superior energy efficiency and ride quality. Technically, the absence of a gearbox eliminates frictional energy losses (typically 20-30% in geared systems) and the need for oil lubrication. The motor is compact enough to be mounted directly to the guide rails within the hoistway, saving significant building space by eliminating the machine room. The control system uses high-resolution encoders (often 2048 pulses per revolution or higher) to provide millimeter-accurate floor leveling and an exceptionally smooth acceleration profile. This engineering approach not only reduces the carbon footprint but also results in a nearly silent operation and a long service life with minimal maintenance.

Core Solutions for Every Need

Tailored Solutions for Premium Residences

Space & Energy Conscious Scenarios

  • High-end villas where a separate machine room is not feasible or desirable due to roofline restrictions.
  • Green building projects (LEED/BREEAM) that require the highest level of electrical efficiency for vertical transport.
  • Modern apartment complexes where space maximization is critical for the developer’s ROI.
  • Luxury penthouses where the elevator motor must be silent enough to be installed adjacent to living areas.
  • Historic buildings where the addition of a machine room would violate preservation regulations.
