TIRLIFT 2 winches are lifting and pulling machines manufactured according to the standards and
regulations in force.
6.1 Technical description
All versions
Rigid steel and cast aluminium structure.
Mechanically welded steel drum with wide flanges for safe and rational fastening of the
rope.
Single or three phase asynchronous motors.
Watertight reducer in oil bath with helical gears.
Single or three-phase standard power socket.
Emergency stop as standard.
Optional: integrated end limit switch.
Low Voltage versions only:
24 V or 190 V direct control electromagnetic brake.
Electrical equipment under watertight cover.
Very low voltage, 24 V remote control with socket – IP 65.
220/380 V three-phase control – IP 55 double insulation.
Speed variation versions only:
190 V direct control electromagnetic brake.
Electrical equipment under watertight cover.
Very low voltage, 24 V remote control – IP 65.
6.2 Operation:
The load and winding speed of the rope on the drum are obtained by reducing the rotation movement
of the electric motor via a shaft mounted helical gear unit.
Outside the motor's operating phases, a mechanical automatic brake stops and keeps the load in
position.
The brake for the speed variation and Low Voltage versions is independent and is electrically
controlled.
In Low Voltage version, the motor is controlled on and off using a three-button wired remote control
(up/down/emergency stop).
In the speed variation version, the motor rotation speed is adjusted using a potentiometer on the
remote control
.
The acceleration and deceleration phases are managed by the machine to prevent
sudden starts and stops (and progressive).
