Q&A's for Sesame Traversing Lift
Product Definition & Overview
Q: What is the Sesame Traversing Lift? A: The Sesame Traversing Lift is unique in that it sits in front of the bottom step riser, rises vertically up to 660mm, and traverses horizontally up to 850mm. Unlike other Sesame systems that sit within stairs, this lift takes up space in front of the bottom step riser and doesn't require space below the stairs or upper landing.
Q: What makes the Traversing Lift different from other Sesame products? A: The key difference is that it sits in front of the bottom step riser rather than within the stairs. It's also typically cheaper than products like the Kensington, Mayfair, or Knightsbridge, and doesn't require excavation below the stairs or upper landing.
Q: Who is this lift suitable for? A: The standard version is for seated users only. Manual removable handrails (1100mm high) can be added for standing users. Permanent handrails and gates can be provided by special design with additional cost.
Technical Specifications
Q: What is the maximum rise height? A: As of October 6th, 2025, the maximum rise is 660mm.
Q: What is the maximum traversing distance? A: The lift can traverse up to 850mm horizontally (approximately three treads at just over 280mm each).
Q: What are the platform dimensions? A:
- Platform width: 1226mm
- Platform length: 1573mm
- Minimum usable space width: 1067mm
- Usable space length: 1557mm
Q: What is the minimum pit depth required? A: 310mm below lower landing finished floor level, allowing for 20mm cladding on the lift pit.
Q: What are the pit dimensions? A:
- Pit width: 1358mm
- Pit length: 1646mm (measured from the bottom step riser going forward)
Installation Requirements
Q: Can the lift be installed without modifying existing stairs? A: Yes, typically the starting point would be the existing finished clad bottom step riser, with no modifications to the stairs required.
Q: Can this lift be installed externally? A: Yes, the lift can be installed both internally and externally. External installations require appropriate drainage solutions and use galvanised mild steel or stainless steel construction.
Q: What drainage options are available for external installations? A: Three options:
- Gravity drain (preferred) - pit floor slopes to local drain connection
- Sump pit and pump inside lift pit (requires lift to be raised for engineer access)
- Separate sump chamber with surface hatch outside lift pit (preferred when gravity drainage isn't possible)
Q: What materials are used for internal vs external installations? A:
- Internal: Mild steel painted with stainless steel trims
- External: Galvanised mild steel or stainless steel
- Coastal/marine environments: Grade 316 stainless steel (rather than standard 304)
Q: What space is required in front of the bottom step riser? A: A pit measuring 1646mm long × 1358mm wide × 310mm deep is required in front of the existing bottom step riser.
Safety Features
Q: What safety features does the Traversing Lift have? A:
- 100mm tow guard that rises around the platform
- Upper landing side tow guard independently lowers to release user
- Emergency lift lower key switch
- IP-rated electric actuators for external use
- UPS battery backup system (standard)
Q: What happens if there's a power failure? A: The standard UPS battery backup system will power the lift to return it to lower landing finished floor level, allowing safe evacuation.
Q: How does the tow guard system work? A: When the lift rises, tow guards rise 100mm around the platform to prevent wheelchair wheels from rolling off. The upper landing side tow guard independently lowers when the lift reaches the top, allowing the user to exit safely.
Control Systems
Q: What control options are available? A: Three main options:
- Button station on the lift for independent control
- Removable handheld post (no buttons, just for holding)
- Remote control for trained users (allows independent use without controls on lift)
Additionally, button stations at upper and lower landings are required to call the lift.
Q: Can the lift be controlled independently? A: Yes, wheelchair users who have been given training can be provided with a remote control to independently operate the lift, or a button station can be mounted on the platform.
Q: Where can the landing button stations be mounted? A: Button stations can be:
- Wall-mounted (flush or surface)
- Mounted on pedestals
- Clamped to glass balustrades (if nearby)
Customization & Finishes
Q: Can the platform be customized with different cladding? A: Yes, any cladding thickness can be accommodated, but thicknesses greater than 20mm will require a bespoke platform and will increase the pit depth. This is considered special design.
Q: What are the standard finishes? A:
- Trims: 6mm stainless steel (brushed finish) or anodized aluminium
- Standard visible elements: Stainless steel brushed finish
- Frame: Aluminium panels (can be anodized to different colours at additional cost)
Q: Can different finishes be applied? A: Yes, options include:
- Electroplating on steel elements
- Powder coating on steel elements
- Anodized aluminium in various colours (additional cost)
Machine Room Cabinet
Q: What are the machine room cabinet dimensions? A:
- Height: 1615mm
