Product Code : SCL-PLE-10417
The Pulley Block with 3 Pulleys from Lab Glassware Manufacturer is a physics laboratory apparatus used for demonstrating mechanical advantage, load lifting, tension, force direction and simple machine principles.
Quick answer: This block-and-tackle style apparatus uses three pulleys to multiply mechanical advantage, allowing students to lift a heavier load with less applied force while observing the trade-off in rope distance pulled.

Understanding Mechanical Advantage
Combining multiple pulleys reduces the force needed to lift a load, at the cost of pulling a longer length of rope — a foundational simple-machine concept. This apparatus builds directly on single-pulley setups like the Pulley with Mounting Clamp, letting students compare force reduction across different pulley configurations.
Frequently Asked Questions
Q: What does this pulley block demonstrate?
