Launching Trolley/Winch System: Moves the precast girder along the machine and positions it accurately.

2. Power & Control System
Hydraulic System: Powers lifting, positioning, and movement of the machine.

Electric Control System: Manages machine functions like movement, lifting, and launching.

Remote Control Panel: Allows operators to control functions from a distance.

3. Lifting & Transportation Mechanism
Lifting Jacks: Hydraulic or mechanical jacks for lifting the girder into place.

Trolley System: Moves the girder along the machine from storage to installation position.

Rail or Track System: Guides the movement of the trolley and the machine itself.

4. Safety & Stability Features
Braking System: Ensures controlled movement and positioning.

Anti-Tipping Mechanism: Prevents accidental tilting or falling of the machine.

Load Sensors: Monitors weight distribution and prevents overloading.

Emergency Stop System: Quickly halts operations in case of malfunction.
