structure and principle of a cable winch
| Code | TM125 |
Description:
- Cable or hoist winches are machine elements that are classified as transmission or conversion elements.
- In a cable winch, a supporting cable is wound on a cable drum by means of a gear transmission.
- This allows loads secured to the supporting cable to be moved.
- The TM 125experimental unit is used to study the hoisting velocity and force transmission of a cable winch.
- It also demonstrates the function of a return stop.
- By considering equilibrium states, it is possible to determine force transmission and efficiency.
- The two cable drums are mounted on ball bearings.
- The forces are generated by weights and can be varied quickly and easily.
