@prajwol_dhital: A counterweight is a heavy mass placed on the back (short arm) of the crane to balance the load being lifted on the front (long arm). Imagine a see-saw. If one side is heavier, it tips over. A tower crane works on the same principle. * Front (long jib): Lifts heavy materials like concrete, steel bars, and formwork. * Back (counter-jib): Holds the counterweights to balance those loads. #civilengineering #crane #nepal #explained #knowledge
