The Structure and Working Principle of Chain Block

The chain block, also known as the chain pulley, is a mechanical device composed of chains and pulleys for lifting heavy objects. Its principle is based on the principle of lever. Through the combination of multiple pulleys, the applied force can be amplified, so that the heavy objects can be lifted easily.

The chain block is mainly composed of the following parts:

  1. سلسلة: The chain connects the pulley block and transmits power.
  2. كتلة البكرة: Multiple pulleys compose the pulley block, which is connected by ropes or chains to form a multiplier system.
  3. إطار: The frame fixes the pulley block and chain.
  4. يتعامل: The handle controls the winding and release of the chain to lift and lower heavy objects.

ال قناة مغلقة works by dispersing the pulling force across multiple pulleys through their arrangement and combination, thus achieving force amplification. فمثلا, in a simple chain pulley system, using two pulleys means that the pulling force required to lift a heavy object is only half its weight.
