Accurate control and safe operation are ensured by Mount G&Ds electrical components.
The Electrical Production Team specializes in manufacturing core elevator electrical components
such as inverters, ELDs, and CTBs, supporting stable and efficient elevator operation through high-quality components.
Inverters are key components installed within the control panel that precisely control the speed and torque of the elevator. High-performance inverters ensure a smooth ride and energy savings.
WB-VF Inverter – The main model inverter for standard elevator operations, to be used until 2024.
GSP Inverter – Provides powerful performance optimized for high-speed elevators, designed for new model elevators following the WB-VF series.
PWM Regenerative Inverter – Maximizes energy efficiency through power regeneration functionality.
ELD (Emergency Landing Device) is an essential component that moves the elevator to the nearest floor during a power outage, allowing passengers to safely exit. It ensures passenger safety in the event of a power failure and is a mandatory inspection item included in elevator safety inspection standards.
Check for battery discharge and verify the rated voltage.
Check if the emergency rescue function operates and verify for errors after power is cut off.
※ This is a mandatory inspection item according to elevator safety inspection standards.
CTB (Car Top Box) is a core control device that manages various signals from the elevator car to ensure smooth elevator operation. By controlling signals accurately, it guarantees stable elevator performance.
Main PCB – Acts as the brain of the elevator control system
CAR Control Module – Controls internal signals of the elevator
DOOR Control (DOOR INVERTER) – Enhances door opening and closing accuracy and safety
Circuit Breaker – Electrical protection device
Car Top Box – A core module housing key components at the R&D Center (Research & Development Center)
Precision Machining & Durability Enhancement
Reinforcements (Structural Frame) – Metal frames for reinforcing elevator structures
CONTROL PANEL – Elevator electrical control panel cabinets
Inverter Enclosure – Metal case for protecting inverters
Car Top Box, ELD Cabinet – High-strength sheet metal for protecting electrical components
Precision Elevator Door System
HDO (Hatch Door Operator) – Elevator landing door operating mechanism
Car Door Operator – Car door opening and closing system
Locking Device – A mechanism for securing and operating the landing door without a power device
Key Structure of the Door Bottom
Hatch Sill – Positioned at the bottom of the door, serving as the door rail.
Safety Devices
Slack Rope Switch – A safety device that prevents slipping and overspeeding of the elevator.
When the car operates faster than the normal speed, the main elevator rope is momentarily tightened to maintain safe operation.
