The most interesting thing about the ancient elevators is that they were just mere cabs that were pulled up and down by animals or manual laborers. Over time, these have evolved to hydraulic and digital systems that are more complex in nature.
You can find elevators in many buildings in the world today. Each state has their own code of how to go about using them, but the code does not differ a lot from state to state. Most of them incorporate the same rules.
- The general requirements are the same
You find that with most residential lifts have similar general requirements and code of operation. Most of the rules and regulation give guidelines about building and usage. They tackle issues on construction, maintenance, repair, inspection, testing, alteration and operations.
Apart from the building codes and regulations that have to pass before it starts operating, each lift is required to have a serial number that is easily viewable in the cab as well as the driving mechanism. This helps to check for permits as well as maintenance follow up. Maintenance and safety measures observation is a mandatory requirement as well.
- Requirements for physically challenged people
Residential lifts must accommodate physically handicapped people. For this reason, they should come with a support rail whose dimensions are given by the construction code. Modern lifts are also required to have braille numbers placed on the call buttons. If a building is more than three stories high, then it must have a lift that can it a wide ambulance stretcher.
- Annual inspection is a must
Most states give annual inspection of all public lifts and elevators as a requirement. A trained professional must conduct the inspection. Most of the time they are inspected by certified elevator inspectors who are sent from the municipal councils. Some states offer these services while others require you to do it on your own, and then give them proof of inspection when they come to confirm.
