In this case, our engineers turned a fast-moving call into a clear, ordered Serviceable Spares Pack for a bespoke hidden platform lift at a luxury hospitality site. The goal: identify the parts most likely to be needed during commissioning and early life, reduce site risk, and ensure rapid swap‑outs without over‑ordering.
The Challenge
A complex hidden lift comprises actuators, cams, scissor assemblies, roller blinds, tape switches, stair hydraulics, gate hardware, sensors and a hydraulic power unit—each with its own suppliers, stock codes and lead times. In this enquiry, the team needed to turn raw model references and engineering dialogue into a right‑sized spares list: comprehensive enough to de‑risk the project, but disciplined enough to avoid “ordering a second lift.”
Sesame’s Approach
Sesame engineers worked collaboratively through the model and transcript, grouping parts by subsystem (Lift Lid/Wheel‑Stop, Scissor Lift, Stairs, Gate, Button Stations, Hydraulics) and tagging items by risk, criticality and replaceability. They favoured items with realistic wear or impact risk, tricky lead times, or those that can halt commissioning if missing. Where drawings referenced supplier‑specific part numbers, they captured both the Sesame part code and the vendor/manufacturer reference to keep procurement flexible. This disciplined method ensured a lean, effective parts set.
Highlights from the transcript review
Instead of building a bulky, expensive kit of everything imaginable, the transcript review highlighted that most components in our hidden lifts are engineered for durability. As Andy noted, nylon wheels and bearings “never wear out”, and even the critical bearings in the gate assembly have negligible duty. Our engineers concluded that a few targeted parts—such as lower roller wheels, limit switches and sensors—are more likely to need swapping, while the core mechanisms can be trusted to perform reliably for years.
This reinforces Sesame’s design philosophy: build to last, prepare smartly. The resulting spares pack isn’t a shopping list—it’s a confidence kit that underlines the reliability of the lift’s core systems while giving operators the assurance that if anything does need attention, they’ll be back up and running without delay.
The Outcome
The team delivered a single, tidy Serviceable Spares Pack that:
- - De‑risks commissioning by covering the highest‑probability failures In this case, Sesame turns a technical transcript into a clear spares pack plan for a bespoke hidden lift—fast to order, easy to store, and ready on site.
- model and transcript.
Why This Matters
A well‑judged spares pack is insurance for programme and reputation: it avoids unnecessary re‑visits, protects uptime for premium venues, and keeps heritage‑sensitive sites running without visible disruption. It also creates a repeatable pattern for similar projects—a blueprint for “what to stock” on complex hidden lifts.
Q&A
Q1. What did we not include—and why?
Bulky aluminium tape‑switch extrusions and generic hoses. Extrusions add volume/cost, while hoses require exact measured lengths and fitting orientations; they’re best made to order.
Q2. Why order “sets” of pins, cams and rollers?
Sets preserve symmetry and tolerances, reduce mixed‑wear behaviours and speed the swap (one visit, full restore).
Q3. How did we handle handed/mirrored parts?
We used the M1 mirror conventions and explicitly listed _MIR part variants to prevent left/right mix‑ups on site.
Q4. Why keep decals and only swap button cores?
Decals rarely fail; EAO cores/bulbs are the service items. This keeps the look & language consistent while restoring function fast.
Q5. What single hydraulic item makes the biggest difference?
The accumulator set at 60 bar — it’s compact, high‑impact for performance stability and a common bottleneck if unavailable.
