Key Takeaways
-
Wheelchair lift autonomy balances independent use with safety and BS 6440:2011 compliance.
-
Rising barriers offer full containment but require a deeper pit and higher cost.
-
A rising button post or removable control post works for seated users but needs staff to switch on, limiting unsupervised use.
-
Clear procedures, keys for regular users, intercoms for visitors, ensure only seated users operate the lift.
Introduction
Selecting the right accessibility lift is critical for both user independence and compliance. In projects where budgets and space are tight, clients often weigh the benefits of fully enclosed lifts against those of simpler, lower-profile designs. This article compares three Sesame Access solutions that support wheelchair lift autonomy without compromising safety.
At‑a‑Glance Summary
-
✅ Automatic rising barriers – full enclosure; deeper pit; suited to mixed-use environments
-
✅ Rising button or removable post – shallower pit; lower cost; staff must switch on; seated users only
-
✅ Dual-use platforms – accommodate seated and standing users; larger footprint; requires modifications to top step
-
✅ Key vs intercom – regular users hold keys; visitors call through intercom for safe operation
Achieving Wheelchair Lift Autonomy: Rising Barriers vs. Rising Post
When the stairs retract, an automatic barrier system creates a physical enclosure around the platform—approximately 1,100 mm high. This design provides full autonomy: a wheelchair user simply presses a button, and the lift operates without staff intervention. The downside is a deeper pit and higher investment because of the mechanism required to raise the barriers.
A rising button post or removable control post emerges through the platform, allowing the user to control the lift while remaining seated. This simpler configuration requires a shallower pit and is more budget-friendly, but because there are no surrounding barriers, the lift must be switched off between uses. Staff must confirm that only seated users operate the lift.
User Autonomy in Wheelchair Lift Design
Autonomy depends on how users access and activate the lift. In buildings where the system uses a removable post or rising button, regular wheelchair users are issued keys for independent operation. Visitors arrive at the lower landing, ring an intercom or doorbell, and a staff member verifies that a wheelchair user is requesting access. The staff member then switches on the lift, after which the visitor can operate it independently. This procedure ensures compliance with BS 6440:2011 and reduces the risk of standing users attempting to use a seated-only lift.
Comparing Lift Configurations: Mayfair, Knightsbridge, Westminster
| Feature | Mayfair Stairlift (removable post) | Knightsbridge Stair Lift (rising button) | Westminster Equality Act Lift (automatic barriers) |
|---|---|---|---|
| User Type | Seated users only | Seated users only | Seated and standing users |
| Activation | Staff switches on; user controls via removable post or remote | Staff switches on; user controls via rising button | Always left on; user presses button |
| Pit Depth | Shallower | Deeper (to accommodate rising post) | Deepest (to house rising barriers) |
| Platform Size | Compact | Compact | Larger platform; top step receded |
| Typical Use Case | Offices with known users; heritage sites | Offices or reception areas with frequent wheelchair users | Public buildings; shared entrances requiring unsupervised operation |
These models demonstrate how Sesame tailors its designs. The Mayfair Stairlift offers a removable control post for situations where staff assist new users. The Knightsbridge Stair Lift adds a rising button post for users to hold and control, which provides security and ease of operation. For environments with a mix of seated and standing users, the Westminster Equality Act Lift delivers full autonomy through automatic barriers, allowing the system to remain on at all times.
Choosing Lift Type Based on Building Use and Budget
In private workplaces or multi-tenant offices with familiar wheelchair users, a removable post or rising-button design minimizes excavation and budget constraints. Staff can manage new visitors safely by switching the lift on via intercom. Public buildings or high-traffic entrances, however, often require fully enclosed platforms to prevent unsupervised use by standing passengers. While these barriers add cost and require a deeper pit, they deliver independence and compliance without requiring staff intervention.
Ensuring BS 6440:2011 Compliance and Annex VIII
All Sesame Access lifts comply with the relevant elements of BS 6440:2011 and the Machinery Directive Annex VIII. This includes:
-
Proper containment for standing users or strict control for seated-only systems.
-
Reliable keys or intercoms to ensure only wheelchair users activate the lift.
-
Emergency stopping and lowering mechanisms that meet safety standards.
Working with accredited manufacturers helps ensure your project meets these requirements and reduces liability.
Why Early Consultation Prevents Redesign Costs
Design teams should clarify:
-
Whether the lift will serve only seated users or both seated and standing.
-
How frequently visitors will use the lift and how staff will manage activation.
-
The available pit depth and space for the platform.
Early collaboration avoids costly redesigns when these factors emerge later in the project. For related guidance, see our Knowledge Hub entries:
Frequently Asked Questions (FAQ)
What defines wheelchair lift autonomy?
Wheelchair lift autonomy means the user can operate the lift independently without staff assistance while meeting BS 6440:2011 safety requirements.
Do automatic barriers improve safety for mixed-use buildings?
Yes. Rising barriers fully contain the lift platform and allow unsupervised use by both seated and standing passengers.
Can a rising-button system comply with safety standards?
Yes, provided the lift is switched off between uses and activated only for seated users.
Who switches on a removable-post or rising-button lift?
New visitors use an intercom to request assistance, and a staff member verifies that the user is seated before switching on the lift. Regular users have a key for independent operation.
Which option suits listed buildings?
The Mayfair Stairlift and Knightsbridge Stair Lift have compact pits and minimal visible hardware, making them ideal for heritage environments.
