The double deck elevator simultaneously operates two vertically connected elevators in one hoistway, and depending on the form of operations, can increase transport capacity by up to 1.8 times standard capacity.
The EL Duo is a world class double deck elevator developed by Hyundai Elevator that uses an ultra strong chain operating system to prevent slippage, and has a Floor Distance Adjustable Device that allows operations in buildings with varying floor height.
Max Operating System: 600m /min
Max Operating Height: 600m (150+ stories)
Max Capacity: 5000㎏
Max Passenger Capacity: 70 persons (35 persons x 2)
Traction Machine: 9 Phase motor (3 Phase motor x 3 Set), 3 Phase motor
Control Panel: Power Regenerating Inverter
By operating two vertically connected elevator cars in one hoistway and servicing two floors simultaneously, transport capacity can be increased by up to 1.8 times standard capacity.
Fewer number of elevator hoistways (up to 30% less compared to single deck units) reduce construction cost and maximizes space utility.
The Floor Distance Adjustable Device can adjust to varying floor heights of up to 7m, allowing for maximum design efficiency.
Use of one traction motor to operate two elevators allow for reduced product weight.
The 9 Phase motor operating system allows safe operations in emergency situations.
THE EL DUO HIGHLIGHTS
Atmospheric Pressure Controller – Pressure control system prevents “ear popping”
Vibration Control System – Reduces lateral vibration to within 5gal and decreases longitudinal vibration by 40%.
Aerodynamic Capsule Cage – Streamlined cage design results in a smoother riding experience.
Mechanical Safety – Fly ball governor, emergency stopping device, and oil buffer, provide a high level of safety.
