Fixed Pulley
Product Code : SCL-PL-12355
Fixed Pulley (SKU SCL-PL-12355) is a cast metal pulley with a deep V-groove and a hook at the top and bottom of its frame, made to demonstrate how a single fixed pulley changes the direction of a force. As school physics lab equipment in India it serves simple-machines lessons, and it can also lift relatively light items. Science Lab Supplies produces the pulley in its own Ambala factory at Plot 448, HSIIDC Industrial Area, Saha, India, supplying schools, colleges, tender contractors and distributors directly.
Specifications
This pulley is made of cast metal and runs with low friction. A deep V-groove keeps the cord seated on the wheel, and the frame has a hook at the top for hanging from a support and a hook at the bottom for attaching a load or another pulley.

Applications and Experiments for the Fixed Pulley
The fixed pulley is used to show that a single pulley changes the direction of the effort without reducing it, giving a mechanical advantage of about one. Hung from a stand or beam, it also becomes the top pulley in compound systems for simple-machines lessons in middle school and Class 9–10 physics.
- Middle-school science: simple machines and how a fixed pulley makes lifting easier by changing direction.
- Class 9–10 physics (machines): measuring load, effort, mechanical advantage and efficiency of a single fixed pulley.
- Class 10 physics: combining fixed and movable pulleys through the bottom hook to compare mechanical advantage.
- Vocational and teacher-training courses: rigging a light load safely over a pulley.
Standard Scope of Supply
The Fixed Pulley is supplied as a single unit as described above, with the cast metal wheel in its frame and hooks at the top and bottom. Cord, a support stand and masses are separate and can be listed on the quotation alongside the pulley if they are required.
Packing, MOQ and Lead Time
Send us the number of pulleys you need, from one demonstration piece to a set for every lab group, and the quotation will state packing, delivery time and price for that count. Double and triple pulleys or mass sets for complete pulley systems may be added to it.
Science Lab Supplies, which holds an Importer-Exporter Code, can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. The quickest routes are the contact page and the enquiry cart; for institutional tenders, see the lab tender page.
Frequently Asked Questions
What is a fixed pulley used for in the lab?
A fixed pulley changes the direction of a pulling force. In the lab it shows that effort roughly equals load for a single fixed pulley, and it forms the top pulley in compound pulley demonstrations.
Why does the frame have two hooks?
The top hook hangs the pulley from a stand, beam or ceiling point, and the bottom hook lets a load or a second pulley be attached, so students can build combined pulley systems.
Is Science Lab Supplies the manufacturer or a trader?
It manufactures the pulley. Production takes place at the company's own factory in Saha, Ambala, India, and quotations are issued directly by that factory to schools, colleges and dealers.
Can the pulley lift real loads outside the classroom?
It is designed for demonstrations but can also lift relatively light items. For any load, stay within what your support and cord can hold and keep people clear of the hanging mass.
