Conventional elevators hoist ways, constructed from cinder block, require a lot of support. Heavy structures potentially require grade beams.
In USA, there is innovation in designing and elevator installation. They develop a modular elevator which is a standard commercial elevator installed into a prefabricated, structural steel hoist way.
The hoist way is sheathed with materials to meet the client building requirements. The modular elevator is then trucked to the site and lifted by crane and set into place in the elevator pit
Although designed to be a permanent part of a building, modular elevators can be relocated.
Modular elevator can be install in 8 weeks after drawings are approved. Typical stick-built elevators have a 5-6 month lead time.
It also faster to install as the elevators arrive completely assembled and ready for installation. Installation takes few days, minimizing disruption at the job site. Conventional elevators generally take about 3 weeks to assemble on-site.
This innovation eliminates the need for a separate equipment room and saves significant energy over other designs.
Modular Elevator also self-supporting. It does not need to rely on building structure for support, making it an excellent choice for retrofit projects.
It safe cost as the elevator are less expensive than stick built. It is constructed out of tubular structural steel, resulting in a lighter structure, in turn resulting in, smaller, concrete pits.
Modular elevator is safer to construct. It is build horizontally, inside a factory. This eliminates the safety issues involved with erecting scaffolding and working outside subject to wind and other elements.
In the appropriate application, modular elevators can reduce the costs and the hassle associated with the construction of conventional elevators.
