Crank and lever mechanism in stone crushing machine

Update date: Apr 26

The stone crusher was built by Pioneer, and possibly dated back to the 1950’s. The machine was diesel driven with many exposed belts and pulleys. One conveyor belt, surrounded by a chute, would take in boulders and rocks and bring them into the crushing mechanism

    Crank (mechanism) Hand crank for a winch on a sailboat - commonly referred to as a winch handle. A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa

    Students are introduced to three of the six simple machines used by many engineers: lever, pulley, and wheel-and-axle. In general, engineers use the lever to magnify the force applied to an object, the pulley to lift heavy loads over a vertical path, and the wheel-and-axle to magnify the torque applied to an object. The mechanical advantage of these machines helps determine their ability to
