How serious is the harm of multiple people holding hands and pulling a gourd

　　Hand pulled hoist is a manually operated lifting tool used for lifting and transporting heavy objects. It usually only requires one person to operate and is prohibited from being operated by multiple people to avoid accidents.

　　The hazards of multiple people holding hands and pulling a gourd include:

　　When multiple people hold hands to pull a gourd, each person's force and direction are inconsistent, which can directly lead to unstable and uncontrollable movement of the gourd, increase the risk of accidents, and may result in personal injury or object damage.

　　Hand pulled hoists have their rated load-bearing capacity, and multiple people pulling them forcefully may exceed their load limit, causing the hoist to fail, break, or be damaged. This will not only damage the chain hoist itself, but also cause harm to surrounding personnel and equipment.

　　During the process of multiple people pulling the gourd together, the distance between personnel may not be sufficient to ensure a safe distance. This may result in personnel colliding, getting injured or trapped, increasing the risk of accidents.

　　Therefore, it is strictly prohibited for multiple people to forcefully pull the chain hoist. Operators should follow the principle of single person operation and use the chain hoist according to the correct operating methods and safety requirements.

　　The difference between the lifting chain and the zipper strip of a chain hoist

　　Friends who have used a chain hoist know that it has two types of chains, one is a lifting chain and the other is a zipper strip. The materials and functions of these two types of chains are different. Today, we will introduce these two types of chains to you.

　　The lifting chain is made of high-strength alloy steel and manufactured by boiling black. It has a dark appearance and mainly plays a load-bearing role. The hand zipper strip is galvanized and has a silver white appearance. It drives the hand chain wheel to rotate the internal parts and has a starting effect.

　　Besides their appearance and function, their diameters are also different. The diameter of hand zipper strips is usually 5 millimeters, while the diameter of lifting chains can be 6 millimeters, 8 millimeters, 10 millimeters, or even higher. This is because the strength of hand zipper strips is much smaller than that of heavy chains due to different forces.

　　The two types of chains of the chain hoist cannot be used interchangeably. When replacing them, users must pay attention to this issue. If the two are installed interchangeably, it will bring safety hazards to the lifting operation, which may cause heavy objects to fall and personal injury.
