Étude de cas sur les ascenseurs à piston | Installation sans fosse à travers le sol pour la rénovation d'une usine

POSTED: 4/23/2026

Besoin du client

Client: Suzhou Liliang Construction & Decoration Engineering Co., Ltd. (Factory renovation specialist)
Projet: 2 reciprocating lifts for a Jiaxing factory
Principaux défis: Floor penetration + basement installation + 4.65m suspended column + 3 stops + C‑shaped access + only 2650mm beam spacing

Liliang needed to vertically transport construction materials from basement to three working floors. During construction, the plan changed: instead of a ground‑floor pit, the floor was opened and the lift must be anchored to the basement floor (4.65m below first floor), creating a suspended column. Beam spacing is just 2.65m square – extremely tight. Requires 3 stops, C‑shaped access (1600mm direction), 500kg capacity, 16.4m travel.

Solution

Pit‑less through‑floor design: Columns extended 4.65m downward through floor slab, anchored to basement floor – no civil pit needed.
High‑power drive: 9.2kW SEW motor with brake + VFD (0‑40m/min) – ample power reserve.
Dual mechanical fall protection: 2 safety gears + polyurethane buffer.
Compact layout: Car W1600×L1600×H2700mm, T90 rails, 16A chain, RAL7035 finish.
Accès en forme de C: Entry from one side, exit from adjacent side – ideal for tight spaces.
