Elevator fabrication is quite expensive, in both labor and parts. It is often the longest road to success. Low rise structures that require accessibility often development plans to use modular elevator technology instead, and enjoy the significant benefits.
Installing standard elevators can be quite the chore. Step one, first requires that a pit to be built and a hoist way fabricated and set up, from wood, steel or concrete block. Components are then taken to the site and put together at the hoist way.
Modular elevators are commercial elevators installed into a prefab structural hoist way. That steel hoist way structure contains the elevator car, rails, controls, and drive system all inside of it. It is covered over with materials to satisfy the building code requirements. The modular elevators are then taken to the site and hoisted by crane so as to be set into position at the elevator pit. After installation, functionality is exactly like a stick built elevator, and is properly maintained the same way.
Normal standard stick built elevators take weeks for on site assembly, and that doesn’t include the man hours lost building the hoist way. Lead-in times
can also be as long as five to six months. Resolving the situation regarding the elevator versus the hoist way, and the hoist way versus the pit, to ensure all required codes are passed and approvals are satisfied, can slow down progress.
To lower these delays and move through the process, some conventional elevators used are over designed. Faster approval happens but higher system prices also are incurred.
Installing modular elevators, that arrive fully and completely assembled, can take only a few days. In addition, with the systems and structures engineered in advance, the design process all is all but non existent upfront. Engineering hours and financial burdens can be avoided due to ready for installation systems, in about eight weeks or so.
The task at hand is just a story of getting the hookup done, and then making all the adjustments to it. Many of the trades normally necessary at the site, are not needed, and therefor all becomes easier and simpler.
Standard elevator hoist ways, built of cinder block construction, require much more in the way of support. Heavier structures will certainly greater levels of support such beams and caissons, which always increase costs and man hours.
Modular elevator systems, being self supporting, and making use of tubular structural metals, means a lighter overall structure, and that translates into smaller concrete pits. No need to be dependent on building structures to support it, and it also makes them a great choice for retrofit projects.
Also there are alternative technologies to choose from which provide benefits over and above the more traditional elevators, including elevators operated by a hole less hydraulic lift, lifts operated by jacks, or elevators that make use of machine room less technologies.
The truth is, as tome goes on, more and more pre fab elevators will be used. They save man hours, control costs, and always fit better when pre designed.
