Description
The automated lift system which communicates allows to study the operating cycle of an automatically piloted lift
 It can be supervised by the use of an Ethernet connection
 It also allows to control dynamically the system with an inverter which controls the traction reducing gear’s brake
 The system is entirely delivered, with a theoretical manual and a technical field
 Industrial equipment
 Education concerned: STI2D, SI…
 Electricity: 230 VAC single-phase – 50 / 60Hz
 Volume of the installation L x l x h = 800 x 800 x 2000mm
