SOLKER-MINI Series – Customized for Small Shaft Spaces, Requires Only 100mm Pit – The Ideal Elevator Solution for Top‑Floor Duplex Apartments

I. Core Advantage: Industry‑Leading Ultra‑Shallow Pit Technology

Traditional elevators typically require a pit depth of 500mm or more – an almost insurmountable obstacle for top‑floor duplex owners, as digging deeper is often impossible due to neighbors below or basement constraints. SOLKER-MINI incorporates an innovative ultra‑thin platform structure and integrated buffer system, reducing the required pit depth to just 100mm – about the height of a smartphone. Even in existing buildings with no excavation capability, installation is straightforward.

II. Designed for Compact Shaft Spaces

Common challenges when adding an elevator to a top‑floor duplex include narrow shafts and irregular layouts. SOLKER-MINI adapts to shaft sizes as small as 800×800mm, allowing installation in bedrooms, balconies, stair corners, and other limited areas. Scaffold‑free installation further minimizes disruption to daily life.

III. No Structural Modification Required

• No waterproofing damage – The 100mm pit eliminates the need for excavation, preserving the original slab, waterproofing, and rebar structure.

• No overhead machine room – The drive unit can be integrated into the shaft top or side‑mounted.

• Fast installation – Standard projects complete mechanical installation in 2‑3 days, with electrical commissioning right after.

IV. Safety & Comfort

• Multi‑layer safety features – Mechanical limit switches, electromagnetic brake, emergency manual lowering device, and UPS automatic leveling during power failure.

• Silent operation – Permanent magnet synchronous gearless traction machine with operating noise below 48dB – no disturbance to family or neighbors.

• Smooth ride – Variable frequency speed control ensures jerk‑free starts and stops; safe for seniors, children, and pets.

V. Customizable to Any Interior Style

Cabin finishes include mirror stainless steel, wood grain, leather, and artistic glass. Door options: manual swing or automatic center‑opening. Control panels can be flush‑mounted or surface‑mounted to blend seamlessly with your home decor.

VI. Real‑Life Application Example

A top‑floor duplex resident in an older Shanghai community faced steep stairs and an elderly family member with knee pain. The only possible shaft location was a corner of the balcony, with a neighbor’s bedroom below – no excavation allowed. After installing SOLKER-MINI, only 100mm pit depth was needed (the finished floor remained nearly flush with the original floor). No extra space was consumed, daily mobility improved dramatically, and no construction complaints were raised.

VII. After‑Sales & Warranty

• 2‑year full system warranty, 5‑year warranty on major components.

• Service centers in major cities; lifelong maintenance with 24/7 emergency response.
