We are leaders in the market for providing best range of Manual Chain Pulley Block
A chain pulley block, commonly referred to as a chain hoist, is a mechanical device used to lift heavy loads. Its strong points can be highlighted in several key numerical aspects:
\n\n
1. **Load Capacity**: Chain pulley blocks come in various load capacities, typically ranging from 0.5 tons to over 100 tons, allowing them to handle a wide variety of lifting tasks.
\n\n
2. **Lifting Height**: The lifting height of chain pulley blocks can vary, typically from 3 meters (10 feet) to 30 meters (100 feet) or more, depending on the model and application.
\n\n
3. **Gear Ratio**: Many chain pulley blocks operate on a gear ratio of 4:1 or 5:1, which means that for every 4 or 5 turns of the hand chain, the load is lifted 1 time the distance.
\n\n
4. **Weight**: The weight of the chain pulley block itself can range from a few kilograms (around 5 kg for a small model) to several hundred kilograms for heavy-duty models.
\n\n
5. **Chain Length**: The length of the chain can vary but often ranges from 5 to 20 meters, depending on the model and intended lifting height.
\n\n
6. **Safety Factor**: A typical safety factor for chain pulley blocks ranges from 4:1 to 6:1, meaning the block can handle 4 to 6 times its rated load safely.
\n\n
7. **Efficiency**: The mechanical efficiency of a chain hoist can range from 50% to 80%, meaning that a significant portion of the input effort is converted into lifting power.
\n\n
8. **Durability**: High-quality chain hoists are often designed for thousands of cycles, with some rated for over 10, 000 lifting cycles, depending on usage and maintenance.
\n\n
9. **Speed**: The lifting speed can vary based on the model and the load capacity, typically ranging from 2 to 10 meters per minute.
\n\n
These numerical strengths make chain pulley blocks highly effective tools for lifting and moving heavy objects in various industrial and construction settings.
