What is the difference between single-wheel and multi-wheel pulleys of lifting tackle?

The pulley is an important part of the lifting tackle and plays a role in guiding the rope operation and carrying the weight during construction. The pulley of the pulley is not single. It is divided into multiple wheels and single wheels. Different numbers of wheels have different functions and performances. When choosing, you can choose the appropriate number of wheels according to the needs of the construction, but before choosing, you must first know the difference between single wheels and multiple wheels. What is the difference between wheels.


The design of pulleys into single wheels or multiple wheels must be based on product requirements. Only by clearly understanding the differences and characteristics of the two can we know what number of wheels to choose for what construction conditions.

First of all, the appearance and structure of single-wheel and multi-wheel pulleys are different. Single-wheel pulleys have only a single lifting pulley, while multi-wheel pulleys have two, three, four, five or even more. It is very easy to identify.

Secondly, their lifting tonnage is also different. Generally speaking, the more wheels the pulley has, the greater the lifting tonnage is. Therefore, multi-wheel pulleys are usually used when lifting large-tonnage heavy objects.

In addition, their use methods are also different. The single wheel has a smaller scope of application and lifting capacity and is often used in some small factories, while multi-wheels can be used upright and reversely, and are generally used in mines, shipyards or large-scale construction projects. At work.


The number of wheels of the lifting pulley is different, the working environment is different, and the suitable types of work are also different. Only by clarifying the differences and characteristics of the two can we choose the correct equipment to make the construction safer and more efficient.
