Comprehensive System Overview
Engineered for Excellence, Built for Performance
Innovative Solutions Factory
Suzhou Dongao Home Elevator Co., Ltd. has developed patented solutions for shallow pit environments, specifically for the renovation market. Operating from our 17,000sqm plant in Suzhou, we utilize Germany’s advanced lift production technology to solve one of the most common hurdles in home lift installation: underground constraints. Whether it is high groundwater levels, existing under-floor heating, or basement parking structures below, our low-pit lifts provide a viable path forward without compromising the structural integrity of the foundation. Our team of 100+ members includes R&D specialists who focus on the mechanical synchronization required to operate high-end villa lifts in these restricted vertical envelopes, ensuring the same level of luxury and safety as a standard-depth installation.

Restricted Environment Usage
- Renovations of historic or existing residences where the concrete slab cannot be cut or excavated.
- Coastal properties or areas with high water tables where deep pits would lead to chronic flooding or waterproofing failure.
- Buildings where the elevator is located over a basement, underground garage, or utility tunnel.
- Modern minimalist interiors where a "zero-step" entry is required without a deep floor recess.
- Retail shops or showrooms inside shopping malls where the floor thickness is strictly limited by the building developer.
