In a lift transfer chair, the hydraulic system is a mechanical system that uses fluid pressure to achieve smooth lifting.
If the lift transfer chair cannot adjust its height, it cannot achieve "barrier-free, low-risk" transfers.
Most lift transfer chairs on the market have a nominal load-bearing capacity of:
✔ 100KG
or
✔ 120KG
or
✔ 150KG
They typically won't be lower than 100KG or higher than 150KG.
