Construction and Design
The Spur Gear Lifting ProDynami – 1334 is built around 4 Cobalt Colored steel gear wheels, standard configuration of 2x D=126mm with 84 teeth and 2x D=42mm with 28 teeth, both with a modulus of m=2mm, arranged as one gear set in compound configuration. An optional gear set, with 2x 120 teeth and 2x 40 teeth gears at the same modulus, is available on request. Two anodised aluminium cable pulleys work alongside a driving pulley with a diameter of 70 to 80mm. Gear wheels and pulleys are ball bearing-mounted, and the base plate is made of anodised aluminium. The model is intended for wall mounting.
