Alongside the familiar drive components, rope elevators also require a large number of guide pulleys in different sizes. These guide pulleys are primarily made nowadays from grey cast iron and plastic. The specially modified cast polyamide TECAST GM yellow was selected for this
safety-relevant application.Due to the specific weight of only 1.15 gcbm, guide pulleys made of TECAST GM yellow are approximately seven times lighter than pulleys made of conventional grey cast iron.
