How does the fall arrester work

Fall arrestor is a device that can limit the falling of objects, but it can only brake and lock quickly within a limited distance, not all distances and speeds can be limited. Fall arrestor is generally used in the hoisting of goods, mainly to protect the personnel operating on the ground from the damage of goods and heavy objects. It is a kind of protective equipment. Fall arrestor can effectively protect goods and operators.

There is no need to change the suspension point within the service radius of the fall arrester. During normal use, the safety rope will stretch freely with the human body. Under the action of the mechanism in the device, it is in a semi tense state, so that the operator has no sense of concern. In case of slip and fall, the pulling speed of the safety rope is significantly accelerated, and the locking system in the device will automatically lock. No more than 292 n of force is allowed to pull out the rope, causing no injury to personnel. When the load is relieved, the work will be resumed automatically. After work, the safety rope will be automatically recycled into the device for easy carrying.

The fall arrester control system is made of special steel and treated with special treatment, which is light, anti-wear, anti-corrosion and impact resistant. The shell is made of aluminum alloy, which is light and non-aging. The anti falling device adopts the original "double locking device" structure, which has stable locking, and effectively solves the accident caused by hitting other objects due to excessive falling and swinging amplitude in inclined operation. The safety rope shall be aviation steel wire rope. The sling and safety belt are flame retardant and resistant to high temperature of 200 ℃.

The high-altitude fall arrester adopts the principle of engagement between ratchet wheel and pawl to complete the braking. At the moment of slip, the pawl will be thrown out by centrifugal force under the instantaneous acceleration, and then bite together with the ratchet on the rotating ratchet wheel to complete the braking in an instant. This process is completed in an instant, and the impact force generated is less than 3000n, which will not cause any harm to human body.
