LGS High speed elevator use very advanced technology to realize optimum performance and fficiency. hese advances include the high-efficient permanent magnetic gearless traction machine with dual disk brake, VVVF inverter, Artificial Intelligence, and Data Network System. Optional features and functions including energy-saving regenerative drives and destination dispatching control are available to improve passenger safety and comfort and simplify building management.
Middle & Low speed
LGS Middle & Low speed elevators are applicable to luxury residential building, hotel, office building, commercial building, etc. They can reduce energy consumption and decrease environmental pollution by adopting the highly efficient permanent magnetic gearless traction machine and inverter control system. Its mini machine room solutions make it easy to give flexibility of building design requirements. They also have a variety of excellent aesthetics designed by Korean professional elevator designer while keeping customized options.
LGS machine roomless elevator can optimize building space with efficient shaft utilization. In addition, there is no construction cost for building machine room, which makes it possible to design a flexible building design. High-efficient traction machine and advanced variable frequency drive systems can save more than 30% of energy consumption compared to traditional traction elevator.

Machine Roomless Elevator(MRL)
|Full collective selective
|In automatic running or attendant state,
this function enables the elevator to respond both car calls and hall
Passengers at any service floor can call the elevator by pressing the up call button and down call button.
|The system automatically judges the number
of passengers in the car and compares it with the number of registered
If there are excessive car calls, the system determines that it is nuisance and cancels all car calls. In this case, passengers need to register correct car calls again.
|Car Call Cancellation
|Passengers can press the button consecutively twice to cancel wrong calls.
|Turn Off of Car Light
|If there is no running command within the set time, the system automatically cuts off the power supply to the lamp and fan in the car.
|Full-load direct runnung
|When the car is full-loaded in automatic
running state, the elevator does not respond to hall calls from the
passing floors. These halls calls, however,
can still be registered, and will be executed at next time of running (in the case of single elevator) or by another elevator
(in the case of parallel/group control).
|When the car load exceeds the rated elevator load, the elevator alarms and stops running.
|Button stuck check
|The system can automatically identify
whether a hall call button is stuck and cancel the stuck call,
preventing the condition that the elevator cannot close and run due to stuck hall calls.
|Repeat door close
|If the door lock is not applied after
the elevator performs door close for a certain time, the elevator
automatically opens the door and then closes the
|Automatic door open upon door
|If the system detects that the door lock
circuit is abnormal during door open/close, the elevator automatically
opens and closes the door again,
and reports a fault after the set door open/close times is reached.
|Door open time setting
|The system automatically determines different
door open time for door open for call, command, protection,
or delay according to the set door open holding time.
|Arrival gong disabled at night
|Within the set time period, the arrival gong is disabled.
|Landing at another floor
|If the door open time exceeds the door open protection time but the door open limit signal is still inactive, the elevator closes the door and then automatically runs to the next landing floor.
|The elevator automatically announces information
such as the running direction and next arriving floor
|Forced door close
|When the door fails to close within the
set time due to the action of the light curtain or safety edge, the
elevator enters the forced door close state,
closes the door slowly, and gives a prompt tone.
|The system supports parallel control of two elevators / group control of more than three elevators
|After landing at a floor, the elevator
may move upward or downward due to the load change and the car door
is not aligned with the ground,
which is inconvenient for in and out of passengers and goods. In this case, the system allows the elevator to run to the leveling position in the door
open state at the leveling speed.
|Light curtain signal judgment
|If the door is blocked by stuff during door close, the light curtain acts and the elevator opens the door. This function is invalid in fire emergency state.
|Power failure emergency
|For the elevator configured with standby
power supply, the system uses the standby power supply (ARD System)
to implement low-speed self-rescue
in the case of power failure.
|The control system can be connected to
the terminal in the monitoring room. By using the NEMS software,
you can view the floor position, running direction, and fault state of the elevator.
|In order for park the elevator, if the
parking key is on position the car stop at the specified floor after
finish servicing of all of registered call.
After the car stops at the specified floor, the car light and fan are off automatically and every buttons both on the car operating panel and
hall button box are no more available.
|Fire return Operation
|In case of fire every cars should be returned to the specified floor in order to evacuate passengers safety.
|In case of fire, a fireman can use the elevator which is stopped at the specified floor in order to support fireman for fire-fighting.
