Noun. A very successful way of achieving something


Product Introduction

•  Standard stair lifts and wheelchair platform lifts are completely transformed –  With innovation and engineering excellence at the heart of everything we

do, Sesame lifts are award-winning and forward thinking •  The design of our patented wheelchair lift system considers;

–  Space, function and usability •  It combines a choice of control systems;

–  Practicality, durability and décor. •  A commitment to research and development means our

wheelchair lifts are amongst the most advanced in the industry.


General Description of PartsThe Stairs

•  CE marked in framework form –  Can be finished with any surface

•  Materials can be wood, carpet, stone, marble, etc –  Finishing is the responsibility of others

•  Stairs move on an integral wheel system –  No contact with the adjacent surface material –  Extended stairs suitably designed for pedestrian use

•  Mains Power –  240v 1 ph. 50Hz @ 0.5KW –  Each Step is rated at 125Kg SWL –  Manufactured to Electrical Standard BS 7671


General Description of PartsThe Lift

•  Platform with a travel below 1000mm include; –  Automatic three sided wheel stop

•  Rising 100 mm before the platform rises •  Fitted with;

–  Handrail mountings –  Push button cable entry

•  Surface prepared and ready for surface material attachment •  Scissor lift provided and rated

–  Safe working load of 350 KG or 500 KG •  Subject to the application and weight of the surfacing materials

•  CBE lowered in emergency by key switch –  Powered by an emergency battery supply

•  Meets requirements –  BS 6440 –  BS 5323

•  As amended in 1984 and 1987


General Description of PartsThe Mounting Frame

•  Mild steel composition onto which the Sesame Stairs and Scissor Lift are bolted –  Capacity of 1500 Kgs –  Designed to ensure swift installation


General Description of PartsOperating Controls

•  Push button controls are located in a tamper proof casing and can be sited/specified at per you or your client’s choice –  If required can be adapted for Braille or other special needs


General Description of PartsHydraulics

•  The hydraulic system drives; –  Stairs, lift, gate and rising barrier/button box movements

•  The unit is normally fitted within the top stair and under the platform tray

•  The Sesame system meets full industrial standards with proven reliability


General Description of PartsElectrics

•  The electric control system is based around a programmable logic controller (PLC) and is suitable for outside use –  A single phase, 13 Amp supply, is the only requirement


General Description of PartsGate Operation

•  The control box is normally fitted within the top stair but can be housed to suit the environment

•  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 –  Fitted counter balance valve allows the gate to released by light force in

an emergency


General Description of PartsEmergency Back Up

•  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


General Description of PartsPit Trim

A Stainless steel trim is designed and supplied to site prior to installation This sets out the dimensions of the lift and provides a guide for the formation of the pit walls


General Description of PartsPit Trim

Recess in pit trim to allow permanent on lift button box to move up and within pit. This design feature can be removed by using a rising button box


Ascent Sequence


Descent Sequence


Main Components


Standard Pit Dimensions

•  Pit Length –  2370 mm for one Wheelchair user only –  2520mm for one Wheelchair user + accompanying person

•  Pit Width 900mm (Minimum) –  To suit installation

•  Pit Depth –  Installation with solid scissor surround

•  Rise of stairs plus 150mm –  Installations with roller shutter scissor surround

•  350 To 600mm

•  Notes: –  Full pit depth only necessary from pit front to front face of top stair –  Minimum pit depth below stair box area is 20mm. –  Pit dimensions will vary with bespoke installations, i.e. rising barriers etc.


Rising Button Box

•  In architecturally sensitive areas a permanent button box may not be feasible –  To overcome this Sesame offer a rising button box system that remains

hidden until the steps have retracted and lift is called upon •  This feature requires additional design and pit requirements


Rises Over 1 Metre

•  Once a lift travels over 1M the user must then be enclosed on the lift platform on all four sides. –  There are various options available, some of which are represented in the

3D drawings overleaf •  They are;

–  False stair option –  Solid partition –  Barrier Option


Rises Over 1 Metre Variants

False Stair Op:on Solid Par::on Barrier Op:on


Gate Mechanism

•  If no additional void space is available for the rising barrier option a more compact solution is available in the form of an automatic gate

•  The gate mechanism can be located immediately below FFL –  Secured at the top of the gate post

•  For a free standing gate post the mechanism must be located further below ground and the drive shaft will be secured to an adjacent fixing point –  The space requirements are detailed below


Restricted Pit Depth

•  With a restricted pit of 80-220mm depth an alternate design is available –  The lift mechanism secures to an adjacent structural support and is

enclosed in 150mm deep box that can be designed to blend into its surroundings

•  The lift plate is recessed 80mm into the ground •  With over 220mm of pit depth available our conventional lift

design can be used
