MR-L's

One of the biggest changes that took place in recent years in the elevator industry was the introduction of the “MACHINE ROOM – LESS” ELEVATOR (MR-L). The name speaks for itself, literally, no machine room – when the code will allow it.

The initial thrust to sell the MR-L’s has been to the new construction market. Having said that, the MR-L’s are also planned for modernization projects, replacement of the “old” and installing the MR-L’s for the “new” as the upgraded systems for the replacement – modernization programs.

The traditional elevator systems have the main electrical control and drive systems located in a separate machine room either at the top or, at the bottom of the building. Generally referred to, as ‘overhead’ or, ‘basement’ location. For this article we will refer these as “traditional elevators” with “traditional machine rooms”
