Médium 2.5, the lift for tight shafts

A machine-room-less lift designed for buildings short on space: pit reduced to 300 mm and top floor at 2,500 mm, on a single load-bearing wall.

  • 225 to 630 kg
  • Pit from 300 mm
  • 2,500 mm headroom
  • Single load-bearing wall
Médium 2.5 range

The Médium range, designed by Sodimas, relies on a single load-bearing wall: it fits easily into existing and new buildings and frees up floor space. Its Médium 2.5 version is our answer for the most constrained shafts.

Key strengths

Reduced pit and headroom

Top-floor headroom of 2,500 mm in new and existing buildings, 300 mm pit in existing buildings (1,000 mm in new ones).

Single load-bearing wall

All the mechanics are fixed to one wall: simple integration and more room in the shaft.

Gearless and belt

Gearless motor at the top of the shaft, no oil or grease; traction and suspension by flat polyurethane belt.

On-board governor

A belt stretched from the pit to the top of the shaft replaces the governor and its tension pulley: less equipment to install.

Energy efficient

Frequency inverter, automatic standby of signalling and lighting: nearly 50% less energy than an equivalent traditional system, according to Sodimas.

SIL 3 safety

QI Touch controller and SecureMax position sensor at SIL 3 level under EN 81-20.

Frequently asked questions

Can the Médium 2.5 be installed without digging a deep pit?

Yes. In existing buildings a 300 mm pit is enough, and top-floor headroom can go down to 2,500 mm.

Is the Médium 2.5 sold for export?

Yes. We supply it in France and internationally, with documentation and installation support.

Who can maintain it?

Any maintenance company: the QI Touch controller uses an open protocol.
