Double, Triple, Single Lab Pulley
Whatsapp Order
Lab pulleys—available as single, double, or triple configurations—are precision-engineered mechanical devices used in laboratory settings to change the direction of force or lift loads with reduced effort. Typically made from durable materials such as metal alloys or hard plastics, these pulleys consist of grooved wheels that guide ropes or cords smoothly during experiments and mechanical setups. Single pulleys have one wheel, doubles have two, and triples have three wheels, allowing different mechanical advantages depending on the setup. Lab pulleys are essential in physics education, mechanical experiments, and engineering demonstrations where principles of force, tension, and motion are studied.
