CTLN Platform

The CTLN PLATFORM, patented by Saitel in 2008, is a lifting system that allows the full exploitation of the constant power speed curve up to a very extensive ratio (1: 9 times the rated speed).

Alternatively a single inverter controls one of the two motors in mechanical joint that are automatically selected depending on the speed adjustment.

Motor switching takes place while running, without stopping and jerking.

The realized prototype, with a nominal power of 80kW and a 520m rope of 25 mm diameter, has performed a 28m/min speed line with 12t load and a 260 m/min speed line with 0.7t.
