Pulley Kit
Product Code : LSK-ES-10483
Pulley Kit (SKU LSK-ES-10483) is an Engineering Science kit for experiments in mechanical advantage using a wheel and axle, single, double and triple sheave pulleys and a Weston differential pulley. Its parts fix to the work panel, where loads are lifted with effort weights. It suits secondary physics, polytechnic applied mechanics and TVET engineering science classes. Produced at the Science Lab Supplies factory on Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, the kit is manufactured for direct supply to schools, colleges, tender contractors and distributors.
Specifications
The Pulley Kit's parts are set out row by row below. In short, it covers fixed, movable and compound pulley arrangements plus a wheel and axle, and its Weston differential pulley carries two sheaves of different size on one pulley to show how that difference sharply raises mechanical advantage.

Applications and Experiments for the Pulley Kit
With the kit, students can hang load and effort weights on different pulley systems, measure the effort and distances moved, and work out mechanical advantage, velocity ratio, work done and efficiency. The set suits the machines chapter of ICSE Class 10 physics, lifting machines in diploma applied mechanics, and TVET engineering science units.
- Fixed against movable pulleys: effort needed for the same load, compared with a stand-alone cast-metal Fixed Pulley.
- Compound systems with double and triple sheaves: velocity ratio and efficiency, a set-up that can also be built from the open-frame Pulley, Inline Double.
- Weston differential pulley: large mechanical advantage from two sheave sizes.
- Wheel and axle: effort and load radii compared.
Standard Scope of Supply
The kit contains the wheel and axle, single, double and triple sheave pulleys and the Weston differential pulley. It is one of a series of Engineering Science kits and is used on the work panel, which is ordered separately; any weights or extra parts you need are listed on the quotation.
Packing, MOQ and Lead Time
A quotation can be raised for a single kit or for one per bench in a physics or engineering lab. It confirms packing, delivery time and price for the quantity you name, and school laboratory equipment such as the work panel or spares kit can be added.
A laboratory equipment exporter from India with an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. Kit quantities for each bench can be sent through the contact page or added to the enquiry cart, and bulk tender buyers can start from the lab tender page.
Frequently Asked Questions
What does the Weston differential pulley show?
It has two sheaves of different size on one pulley, showing how that small difference gives a dramatic increase in mechanical advantage compared with simple pulleys.
Which engineering terms does the kit introduce?
Mechanical advantage, velocity ratio, machine efficiency and work done, all found from measurements on the student's own pulley arrangements. The kit builds these ideas through fixed, movable and compound pulleys and the wheel and axle.
Is Science Lab Supplies the manufacturer or a trader?
Each Pulley Kit leaves the Science Lab Supplies factory in Saha, Ambala, India, where it is manufactured, and the same factory quotes buyers directly for one kit or a class set.
Does the kit work without the work panel?
The parts are designed to be fixed to the Engineering Science Work Panel, so order the panel too if your lab does not already have one.
