• Determination of:
    • velocity ratio
    • unwinding speed
    • angular speed
    • efficiency
  • Behavior under load.


  • Study of a winch
  • Drum and driving wheel made of aluminum, gear wheels made of POM
  • 2 sets of weights
  • Safety catch prevents reversal of direction of rotation
  • Anodized aluminum base plate

Winch allows to study a winch concerning its lifting velocity and its load transmission. Additionally, the functioning of a back-run safety device is demonstrated. Load transmission and efficiency can be determined by force equilibrium. Both rope drums are ball-bearing mounted. The forces are generated by sets of weights and can be quickly and easily varied. The model is intended for wall mountings a step-by- step guide through the experiments.
