The Sesame System Skeleton
General Description
The Sesame system comprises a set of retractable stairs, a scissor lift, mounting frame, operating push buttons, a hydraulic drive system, an electrical control system, and a gate operator.
The Stairs
These are CE marked in framework form, ready to be finished with the client’s chosen surface. Materials can be wood, carpet, stone, marble, etc. (finishing is the responsibility of others).
The stairs move on an integral wheel system without contact with the adjacent surface material and the extended stairs are suitably designed for pedestrian use.
The top step is covered by a stainless steel platform tray. This to be clad with the chosen material as the finishing is completed.
Access required to main power source 240v 1 ph. 50Hz @ 0.5KW. Each Step is rated at 125Kg swl. Manufactured to Electrical Standard BS 7671.
The Lift
The lift unit includes an automatic, three sided, wheel stop, rising 100 mm before the lift platform.
The lift platform is fitted with handrail mountings, and push button cable entry.
The platform surface is prepared for surface material attachment.
The scissor lift provided will be rated at a safe working load of 500 KG or 1000 KG depending on the application and weight of the surfacing materials.
The lift can be lowered in emergency by a hand operated valve.
All requirements of BS6440 and BS 5323 as amended 1984 and 1987 are met.
Mounting Frame
Mild steel composition onto which the Sesame Stairs and Scissor Lift are bolted.
1500kg capacity and designed to ensure the installation of the manufactured system can be swiftly concluded at site.
Operating Controls
Push Button Controls located in a tamper proof casing. Can be adapted if required for Braille or other special needs.
Hydraulic System
The hydraulic system drives stairs, lift, and gate movements.
Normally located within the top stair and under the platform tray.
The system meets full industrial standards with proven reliability.
Electrics
The electric control system is based around a programmable logic controller (PLC) and suitable for outside use.
Gate Operation
Control box normally located within the top stair.
Single phase 13A supply is the maximum requirement.
A hydraulic gate operator actuates the customer supplied gate. Any obstructive resistance to a gate movement triggers instant reversal.
The operator mechanism is hydraulically locked in the closed position, but can be released by in an emergency by a hand operated valve.
Emergency Backup System (optional)
In the event of mains power failure, the full system automatically switches to battery operation. All functions remain the same with the minimum of four complete cycles.
