Sheave Pulley
A fixed pulley with no sheave changes the direction in which the force is applied to move the heavy load, but it does not change the amount of force needed. Using multiple sheaves gives you a mechanical advantage.
Aluminum Pulley
The Raydafon belts and pulleys are designed specifically for linear motion. They use a rounded tooth profile that guarantees that the belt tooth fits smoothly and accurately in the pulley groove, so when you reverse the pulley direction, there is no room for the belt to move in the groove.
Small Pulley
With the endorsement of our adept and seasoned professionals, we are engaged in offering a commendable range of Campaign Small Pulley. The offered pulley is manufactured by making use of high grade raw material and leading technology in synchronization with the set industrial norms. In line with clients'' variegated requirements, we offer the entire range in various customized options. Clients can avail the entire range of pulley from us at industrial leading prices.
Plastic Pulley
Pulleys are often used as parts of compound machines. They function as helper machines, easing the lifting power. In fact, a pulley system can cut the force necessary to lift a very heavy object in two, four, etc., depending on the designed system. With these pulleys you can study and measure the force and distance trade off with compound machines. These pulleys are good for science experiments as well as functional tasks.
Winch Pulley
The hook on the pulley block is removed and the winch cable line is run over the pulley. The pulley block hook is then replaced and then attached to a strap wrapped on the forward fixed-object. The hook on the winch cable end is attached to the front of the vehicle being pulled-or to a fixed object close to the front of the vehicle.
Cable Pulley
Every product has a unique Manufacturing Part Number label on the inner package that proves it has been qualified,which include Part Number,Model Number and inspection date information;
