Heavy duty lifting pulley

There are significant differences in design and use between heavy-duty pulleys and ordinary pulleys. These differences are mainly reflected in load-bearing capacity, material, structure, and usage environment.

1. Load bearing capacity
The load-bearing capacity of heavy-duty pulleys is much stronger than that of ordinary pulleys. Ordinary pulleys are usually used for light or medium loads, such as household sliding doors, windows, etc., with a load-bearing capacity generally within a few tens of kilograms. Heavy duty pulleys are designed specifically for heavy loads, capable of easily handling weights of hundreds or even thousands of kilograms, and are widely used in industrial, construction, and other applications that require high-strength load-bearing capacity.
2. Material and Construction
Ordinary pulleys are often made of lightweight materials such as plastic and nylon to reduce costs and weight. Heavy duty pulleys typically use high-strength metal materials such as steel and aluminum alloys to ensure their excellent load-bearing capacity and durability. In addition, heavy-duty pulleys have more complex and refined structural designs to meet higher usage requirements.
3. Operating environment
Ordinary pulleys are mainly suitable for relatively mild environments such as homes and offices, with low requirements for weather resistance and corrosion resistance. However, heavy-duty pulleys often need to be used in harsh industrial environments such as high temperature, low temperature, humidity, corrosion, etc., thus requiring higher weather resistance and corrosion resistance.
