Winch Apparatus | ProDynami – 1220
The Winch Apparatus ProDynami – 1220 studies winch lifting velocity, load transmission, and efficiency using ball-bearing mounted rope drums. This Winch Apparatus features aluminum drums and driving wheel, POM gear wheels, and a safety catch that prevents reversal of rotation. It demonstrates back-run safety device functioning with a total transmission ratio of 10. Two sets of weights and a wall-mountable design are included.
The Winch Apparatus ProDynami – 1220 allows the study of a winch concerning its lifting velocity and load transmission. This Winch Apparatus demonstrates the functioning of a back-run safety device, with load transmission and efficiency determined by force equilibrium. Both rope drums are ball-bearing mounted.
Product Overview
Winch allows study of 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 mounting, with a step-by-step guide through the experiments provided for this Winch Apparatus.

Construction and Design
The Winch Apparatus ProDynami – 1220 is built around a drum and driving wheel made of aluminum, with gear wheels made of POM. The driving drum has a diameter of 220mm, and the driven drum has a diameter of 115mm. Gear wheels consist of a small gear with 12 teeth and a large gear with 60 teeth, each with a 2mm module, giving a total transmission ratio of 10. Both rope drums are ball-bearing mounted. A safety catch prevents reversal of the direction of rotation. The base plate is made of anodised aluminum. The model is intended for wall mounting. Forces are generated by sets of weights on the driving wheel (1x5N, 4x2N, 2x1N, 2×0.5N, 1×0.5N guide rod) and the drum (1x50N, 2x20N, 1x10N).
Scope of Delivery
- 1 experimental unit
- 1 instruction manual
