Can a Small Shaft in a Top-Floor Duplex Accommodate an Elevator? SOLKER Delivers a New Solution with Just a 100mm Pit

Say Goodbye to Deep Pits – The 100mm Pit Ushers in a New Era for Duplex Elevators

Many owners of top-floor duplexes share the same feeling: the house is beautiful, but climbing stairs every day is exhausting. For seniors, pregnant women, or those with limited mobility, going up and down becomes a punishment. Yet when you think about installing an elevator, the installer often says:

• “Your shaft is too small. The pit needs to be at least 300mm deep.”

• “Below your floor is the neighbor’s living room – no room to dig.”

• “The project would be too disruptive – structural changes, permits…”

SOLKER solves all these problems at once.

01 Ultra-Shallow 100mm Pit – No Digging, No Beam Modifications

Traditional home elevators typically require a pit depth of 300–500mm to accommodate buffers, car beams, and other components. SOLKER integrates an innovative drive system and buffer mechanism, reducing the pit requirement to just 100mm – roughly the height of two smartphones stacked together.

What this means for you:

• No need to break through waterproofing, underfloor heating, or floor slabs

• No impact on the space below – no neighbor coordination issues

• Retrofitting an old house no longer requires “major surgery”

02 Designed Specifically for Top-Floor Duplexes with Small Shafts

Extreme cases common in duplexes – such as spiral stairwells, corner shafts in L‑shaped spaces, or attic openings smaller than 1m² – are all handled by SOLKER. The elevator can fit:

• Minimum shaft size 0.9m × 0.9m

• Compact yet comfortable cabin, with customizable door openings

• Side‑mounted or cantilevered rails to save core floor space

03 Safe, Quiet, and Stylish

• Safety: Standard UPS emergency leveling, automatic rescue during power outages, and infrared light curtains to prevent pinching.

• Quiet: Permanent‑magnet synchronous motor – operates below 50 decibels, won’t disturb your sleep.

• Stylish: Glass shafts with aluminum alloy frames, or wood‑veneer finishes to match your home decor.

04 Fast Installation – Completed in Just Two Days

In most top‑floor duplexes, installation can be finished within 2 days, without extensive demolition or renovation. SOLKER provides on‑site surveys, custom non‑standard solutions, and one‑stop permitting assistance.

Closing
A small shaft is never a reason to forgo an elevator – it’s a reason to choose SOLKER. With a 100mm pit, true “elevator freedom” finally comes to top‑floor duplexes.
