MEWOI-High quality factory hot sale safety wire rope fall arrestor self retractable lifeline fall arrester
INTRODUCTION
| The fall arrester, also known as speed differential, can quickly brake and lock falling objects within a limited distance. It is suitable for cargo hoisting and protects the life safety of ground operators and the damage of the hoisted workpiece. The product is applicable to the safety protection against accidental falling of the hoisted workpiece when lifting the crown block, and can effectively protect the life safety of ground operators and the damage of the hoisted workpiece objects. It is used in metallurgical automobile manufacturing, petrochemical, engineering construction, power, ship, communication, pharmaceutical, bridge and other high place workplaces. This product is only a part of the system. The fall prevention systems are: vertical life system and horizontal life system. Horizontal life system is widely used. |
Working Principle
The fall arrestor is controlled by the difference of falling speed of objects, and it is hung high and used low. When TXS2 series is used, it is only necessary to span the nylon sling over the structure with solid blunt edges above, hook the iron hook on the nylon rope into the "n" ring, and hook the iron hook on the steel wire rope into the semicircle ring on the safety belt. The suspension point does not need to be replaced within the service radius. During normal use, the safety rope will stretch freely with the human body. Under the action of the internal mechanism, it is in a semi tense state, so that the operator has no sense of concern. In case of falling, the pulling speed of the safety rope will be obviously accelerated, and the internal locking system will automatically lock. The pulling distance of the safety rope shall not exceed 0.2m, and the impact force shall be less than 2949N, which will cause no harm to the person who falls. The work will resume automatically when the load is relieved. After work, the safety rope will be automatically recycled into the device for easy carrying. The anti falling device adopts an original "double locking device" structure, which has stable locking, high safety factor and good reliability, and effectively solves the accidents caused by falling and swaying too much in tilting operation and hitting other objects. The control system of the fall arrester is made of special steel and has been specially treated. It is light, wear-resistant, corrosion-resistant and impact resistant. The shell is made of aluminum alloy, which is light and does not age. The safety rope shall be aviation steel wire rope. The slings and safety belts are flame retardant and resistant to 200 ℃ high temperature. |
Advantage
| Advantages: high strength, wear resistance, durability, mildew resistance, acid and alkali resistance, simple and convenient, safe and applicable. |
Usage Method
The speed difference type automatic controller is fixed and suspended above the operation point. The rope in the automatic controller can be pulled out at any time by connecting the rope in the automatic controller with the upper half ring of the safety belt to operate at a certain position. After the work is completed, when the person moves upward, the rope will automatically retract into the automatic controller. Automatic controller is affected by speed during falling Perform brake control. During the test, the pulling rope is 0.8m long, and it is required that the sliding distance of the simulated human fall shall not exceed 1.2m. |
Index of automatic controller of high altitude fall arrester:
Fall Arrestor (speed difference type automatic controller) ☆ The sealed aluminum metal shell fall arrester is a new patented safety product, which is self controlled due to the change of speed ☆ The anti ratchet double disc braking system can effectively control the human body from falling out of control ☆ The rope can be pulled out at will during operation. Normal operation will not be affected under normal conditions (less than 2m per second) ☆ The specification length is 3m, 5m, 10m, 15m, 20m and 30m. |
Matters Needing Attention
1. The fall arrester must be hung high and used low, and shall be hung on the structure with firm and blunt edges above the user. |
| 2. Before using the fall arrester, check the safety rope and its appearance, and try to lock it for 2-3 times (method of lock test: pull out the safety rope at normal speed with a "click" or "click" sound; pull the safety rope with force, and it should be able to lock it. When you release your hand, the safety rope should be able to automatically recover into the arrester. If the safety rope is not completely recovered, just pull out some safety ropes slightly). Stop using in case of any abnormality. |
| 3. When using the fall arrester for tilting operation, the gradient shall not exceed 30 degrees in principle, and whether it can strike the surrounding objects must be considered when the gradient is above 30 degrees. |
| 4. The key parts of the fall arrester have been specially treated for wear resistance and corrosion resistance, and have been strictly debugged. No lubricant is needed when using. |
| 5. It is strictly forbidden to use the fall protector with the safety rope twisted. It is strictly forbidden to disassemble and refit. It shall be placed in a dry place with little dust. |
