structure and principle of a cable winch

 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.
