The K4E travels at a maximum speed of 150mm/second (9-metres per minute) fully loaded thus capable of travelling between 3-metre levels in approximately 20 seconds. The maximum speed is set by the Australian Standard and is specific to when a person is travelling on the lift platfrom. The K4E has the ability to double its travel speed when it is unloaded for both the up and down motions. This load sensitive over speed (LSOS) is able to provide major reductions in the full cycle time of the lift. Additionally, in order to minimise waiting time in high capacity buildings the K4E can travel at 80% overspeed when being called (unloaded) to the respective level.
The unique drive system relies on fail safe brakes which engage in a matter of milliseconds and doesn’t need to rely on clunky, failure-prone locking pin arrangements to ensure the platform is secure at the entry and exit levels. The lift is managed by a Category 3 safety control system comprising market leading Siemens variable speed drive and sensor technology which constantly monitors critical systems to provide safe operation.
