IB Basics Single Sheave Rope Pulley Block

The IB Basics Single Sheave Rope Pulley Block is a simple mechanical device used to change the direction of a rope or cable while transmitting force. It consists of a grooved wheel (sheave) mounted on a shaft within a frame. The rope or cable is threaded through the groove in the wheel, allowing it to rotate freely.

These pulley blocks are commonly used in various applications such as lifting, rigging, and hauling. They provide mechanical advantage by distributing the force required to lift or move a load over multiple ropes or cables, reducing the amount of force needed by the user.

Single sheave pulleys are particularly useful in situations where only one direction change is needed. They are often employed in conjunction with other pulleys to create complex systems for lifting heavy loads with minimal effort.
