Structure ElevatorFor Existing Buildings / Villas without an Elevator

A structural lift uses a factory-made steel or glass shaft instead of a traditional masonry hoistway. The structure supports the guide rails, machine and landing doors, and can be freestanding or tied into the building.

It is often used for outdoor installations, heritage buildings, temporary structures and retrofits where building a new concrete shaft would be slow, expensive or structurally difficult.

The shaft must be designed for wind, seismic and impact loads, as well as the weight of the car and machine. The foundation and connection to the existing building need engineering input. A glass or open shaft also needs drainage and corrosion protection.

Outdoor lifts should be detailed for the local climate: rain, humidity, heat and dust. Check the finish of the steelwork, the sealing of joints and the maintenance access for the shaft and machine.

A factory-made structure can reduce site work and installation time, but it requires early coordination. The shaft dimensions, door positions and machine arrangement must be fixed before fabrication.

Lifting the structure into place may need a crane and a suitable site access route. Plan the delivery, lifting and temporary works before the equipment arrives.

Inspect the structure, fixings, seals and finish as part of the lift maintenance programme. Steel structures need touch-up painting where the coating is damaged; glass needs cleaning and inspection for chips or seal failure.

If the lift is outdoors, check drainage and weather seals before the monsoon. Keep the pit and machine area dry and well ventilated.
