Business introduction

Saehan elevator

In contemporary architecture, elevators play a vital role as the sole vertical transportation means, ensuring that passengers can conveniently, safely, and comfortably navigate the building. Additionally, elevators hold such significance that they are considered representative of the building's prestige.

Machine Room-Less elevator

Traditional traction elevators required a dedicated machine room above the elevator shaft to house components such as the hoist machine, control panel, and governor. However, with advanced technology, a groundbreaking innovation has compacted essential components, allowing the installation of all systems within a single elevator shaft, eliminating the need for a machine room

Feature2

Machine Room-Less Elevator - Special Advantages

Cost Savings and Quick Construction:

The absence of a machine room results in a shorter construction period, leading to cost savings. With the elevator shaft being approximately 3 meters lower than traditional designs, construction time is reduced, and costs are minimized. In regions with height restrictions, this design allows for an additional floor, enhancing economic feasibility.

Diverse Design Possibilities:

The lack of a protruding machine room on the building's rooftop and fewer height constraints provide opportunities for a more sophisticated and diverse design. This approach aligns well with contemporary trends that emphasize urban design aesthetics and complies with regulations related to height restrictions.


Reduced Noise for Resident Comfort:

Unlike conventional elevators with machine rooms that may cause noise disturbances for top-floor residents, the absence of a machine room contributes to a quieter system, minimizing discomfort for occupants.

Energy Savings:

By utilizing a gearless traction machine with a high-efficiency permanent magnet synchronous motor, typically employed in elevators for buildings with 20 or more floors, the elevator's motor capacity is minimized. This design helps reduce the power infrastructure and overall power consumption for the elevator.

Each component of an elevator has a different lifespan based on usage frequency and maintenance condition. Generally, elevator components can be categorized into parts with permanent usage, such as RAIL and JAMB, components with a lifespan of approximately 10-20 years, including control panels, governors, and hoist machines, and parts with a lifespan of less than 10 years, mainly ropes and operating panels.
