Dream Forest

Inclined Elevators

Location: Seoul

Date of Completion: October 2009

Submitted by: Achim Hütter

Project Description

The City of Seoul planned to convert an old theme park, Dream Land, into an easily accessible park for locals. Called Dream Forest, it took two years to build. An outdoor inclined elevator takes visitors a distance of 67 meters to the entrance of the Art Center. This is one of the first angle-changing inclined elevators in South Korea. After guests ascend its entire length, they stand at the entrance of the observation deck. Another elevator is within the observation tower and runs 47 meters.

Usually the cabin and the landing doors of an inclined elevator are coupled with a mechanical system that allows the car doors to jointly open the landing doors at every floor. This system envisages a motor and coupling skate for the cabin door, whereas the landing doors are engaged through their own lock. The wireless system installed here allows the control panel to check both cabin and landing doors when they face each other without any mechanical engagement. This system allows communication between cabin and landing doors, even though they operate with independent motorization and mechanics.
