Stainless Steel Pulleys China Supplier

Pulley are common lifting mechanisms used for rigging.

A pulley system is used in conjunction with ropes and can be opened on one side to quickly and easily insert a rope without having to remove the load or change the direction of the ropes, by looping the rope through the pulley (around the sheave) several times before hooking to the object.

The force required diminishes proportionately with the number of pulleys or ''loops'' used during the hoist.

These pulleys are made with good quality stainless steel materials and are corrosion proof having long-lasting resistance and durability.

Our range of pulleys is available in standard as well as customized sizes.

What are Stainless Steel Pulleys?

Stainless Pulleys are simple tools without any gears or engines, with one or more wheels on which a rope or cable turns, used to support a taut cable in a circular motion along the pulley or to change the direction of movement, to lift loads, apply force and transmit power. Lifting heavy loads with minimal force, is designed to suspend heavy loads to lighten them.

In nautical terms, the combination of wheel, axle and support housing is known as a ''block''.

Pulley blocks can have driving elements such as ropes, cables, and chains that move on the wheel of the pulley. pulleys can be assembled as a block to provide a mechanical advantage to apply force, or as part of a rope or chains drive to transmit power.

The more wheels in the Pulley, the more times the rope is wrapped around it and the more things it can lift.

How to Choose Pulley?

With regard to choosing the size of the pulley, the diameter of the rope determines the size of the pulley that is suitable for the application. For example, a 7x7 cable should use a wheel diameter at least 40 times that of the cable, a 7x19 cable should use a wheel diameter at least 25 times that of the cable, and a 7x49 is recommended to use 15 times that of the cable.

In general, the more flexible the cable, the smaller the recommended wheel diameter to extend the life of the cable.

A smaller pulley will wear out the cable more quickly and a larger pulley may be too large. As the remaining disadvantages of using a pulley larger than the recommended size are mainly a matter of cost, designers should use the largest size pulley appropriate for the particular application.

Why choose Stainless Steel Pulleys?

Stainless Steel Pulleys Available

Stainless Steel Pulleys are available in a variety of models, from single wheels to 4 wheels. if you want to use a single wheel pulley and a rope to lift a weight to a certain height, you have to pull the other end of the rope down. If you use a double wheels pulley and wrap the rope around it, you can reduce the force required to lift the weight. This is because in this case the pressure is fully supported by the same rope at both ends through the pulley. The four wheels pulley takes advantage of its mechanical advantage, each part of the rope can support 1/4 of the total weight and requires 1/4 of the force to pull, which is less effort than the double wheels pulley.

Pulley

Pulleys, despite their long history, are known for their role and function and are still essential tool in contemporary society. Modern technology has led to advances in materials and manufacturing techniques, resulting in a wide range of stainless steel pulleys.
