    One pulley changes the direction you pull. Two pulleys halve the effort. This pack has the pulley hardware for building a crane that proves it, and a learner can feel the difference by lifting the same load through one wheel and then through two.

    What is in the pack

    • Metal pulley wheels
    • Hook and lifting cord
    • Mounting hardware

    Covers Mechanical Systems and Control in CAPS Technology, Grades 7 to 9. Mechanical advantage is one of the few topics where a learner can put a number to what they built, which marks well.

    Note: basic components only. The crane frame, backing board, tools and glue are not included, and the learner builds the tower themselves.
