Triple Pulley – Three 50mm Polypropylene Wheels with Aluminium Frame

This robust Triple Pulley features three smooth‑running polypropylene wheels mounted within a strong aluminium frame, making it ideal for advanced mechanics and forces experiments. The frame is riveted for maximum strength, while the replaceable bearings ensure long‑lasting, low‑friction operation suitable for frequent classroom use.

Each wheel has a diameter of 50mm, providing consistent and reliable movement when used with standard cords and masses. The three‑wheel design makes this pulley an excellent choice for constructing complex lifting systems and exploring how increasing the number of pulleys affects mechanical advantage and effort.
