The reason why chain hand chain hoists can be used in so many different scenarios is due to their unique design and operating principles: - **Compact and efficient**: They utilize a gear transmission system that is both compact and highly efficient. By leveraging the principle of levers, a small amount of manual effort is required to generate a pulling force that is proportional to the weight of the load. - **Safe and reliable**: These hoists are typically equipped with safety features such as double-pawl brakes and reverse check brakes, which ensure that the load is securely locked in place, preventing it from falling freely. The critical load-bearing components, such as the hooks, have high safety factors; for example, some models’ hooks are designed to withstand 150% of their rated load capacity. - **Durable and long-lasting**: The main components are made of high-strength alloy steel or full-structure steel, and the chains are made of premium alloy materials. The surfaces of these chains often undergo anti-corrosion treatments such as powder coating, which ensures their durability over time. The working principle of a chain hand chain hoist is as follows: When you operate the handle back and forth, it drives the internal gear mechanism and the pawl-brake system, which engage with the chain step by step, thereby lifting or lowering the load. Throughout this process, the brakes remain in place to ensure safety at all times.
