Trezor MRL Elevator

The machine-room-less elevator is the result of technological advancements that often allow a significant reduction in the size of the electric motors used with traction equipment. These newly designed permanent magnet motors (PMM) allow the manufacturers to locate the machines in the hoistway overhead, thus eliminating the need for a machine room over the hoistway.In the past three years the elevator manufacturers have overcome the obstacles to acceptance of the MRL product. All of the other elevator manufacturers are now marketing their versions of the MRL, and the product offering has been expanded to include many of the more popular elevator sizes and speeds. In addition, local code officials have become more receptive to the technology; most are now allowing the equipment to be installed in their respective jurisdictional areas, at least on a case by case basis.MRL are still relatively new to the United States. Our firm is reluctant to promote products that do not have solid and proven track records of reliability. We go to great lengths to validate manufacturers claims and performance records. One manufacturer has recently removed their MRL product from the market and is attempting to redesign and introduce a new offering.
