elevator , Iran
Machine Room Less elevators, known as MRL systems, are based on traction technology using permanent magnet synchronous gearless motors. Rated motor power typically ranges from 3 to 25 kilowatts with electromechanical efficiency above 90 percent. Nominal cabin speed is defined between 0.63 and 2.5 meters per second. Load capacity ranges from 320 to 1600 kilograms with a minimum rope safety factor of 12. Traction sheave diameter is generally selected between 240 and 600 millimeters. The control system operates with VVVF drive technology, ensuring stopping accuracy within ±5 millimeters.
The structural configuration eliminates a separate machine room and installs the traction machine inside the hoistway. Shaft dimensions can be reduced by up to 10 percent compared to conventional systems, optimizing building space. Guide rails are manufactured from cold drawn steel with tensile strength above 370 megapascals. A dual electromagnetic brake is designed to hold at least 125 percent of rated load torque. Annual energy consumption is up to 30 percent lower than geared systems. Safety systems include progressive safety gear and overspeed governor compliant with EN 81 standards.You can order and buy elevator from Iran by contacting us through whatsaap and email.

Disadvantages and Limitations of Machine Room Less Elevators in iran
Machine Room Less elevators offer space efficiency but present specific technical and operational limitations. Installing the gearless traction machine inside the shaft increases maintenance complexity and can extend service time by up to 20 percent. Heat dissipation in confined spaces is challenging, and efficiency may decrease above 40 degrees Celsius ambient temperature. Rated capacity is typically limited to 630 to 1000 kilograms, making them less suitable for very high traffic applications. Improper installation may cause vibration and structural noise exceeding 55 decibels. Emergency rescue procedures in some models require specialized tools and trained technicians. Electronic components and variable frequency drives often have higher replacement costs compared to conventional machine room systems. Compliance with EN 81-20 safety and maintenance accessibility requirements remains mandatory.
