Fall arresters for high altitude operation

 Generally, in high-altitude workplaces such as roofs, factories, elevator maintenance, shipbuilding, space bases, construction sites and so on, most workers at high altitude will be called upon to equip safety components such as fall arresters (fall preventers) when working. The fall arrester is connected with a seat belt for collocation, and one end of the seat belt is tied to the upper worker. When an aerial worker accidentally falls from a high altitude, its fall arresters can act as an emergency lock or buffer to the seat belt to prevent the aerial worker from continuing to fall or to buffer the falling speed of the aerial worker, thus ensuring the personal safety of the aerial worker.           
 At present, there are three main types of fall-proof devices in circulation on the market:           

 Seatbelt elastic stretching crash protector: When a high-altitude worker with a seat belt falls, the elastic stretching seat belt can be used to buffer and slow down the falling speed of the high-altitude worker.            

 A  fall preventer with overlapping seatbelt stitching: When an aerial worker falls, the overlapping seatbelt stitching part will be torn apart due to the force, so as to absorb the falling energy of the aerial worker part, so as to achieve the cushioning effect.            

 Fall-proof device with fast locking function: When a person falls and produces instantaneous pull, the fall-proof device will emergency lock its seat  belt so that the seat belt does not fall continuously.            

 The law of falling accident at high altitude is a universal manifestation of catastrophe which occurs when people combine with related objects in high altitude operation and lose control of abnormal movement against the law of objective things.           

According to the falling mode of human body injury caused by falling accidents at high altitudes, the falling accidents at high altitudes can be divided into the  following types:           

 Cave entrance fall reserved entrance, passageway entrance, staircase entrance, elevator entrance, balcony entrance fall, scaffolding fall; hanging height work fall; asbestos tile and other light situation fall in demolition project, fall in the process of climbing, ladder work fall; roof work fall; other high work fall, such as iron tower Poles, equipment, tall trees, and other falling objects.           

 Construction hoist safety fall arresters is an industrial or construction fall arresters. The fall arresters is also known as the anti-falling safety device of construction elevator. Do you know the principle of safety fall arresters of construction elevator and the use method of fall arresters? The author of the  fall arresters manufacturer is here to tell you the principle of the fall  arresters and the use method of the fall arresters.            

 Principle of fall arresters: When construction hoist works normally, under the action of lifting force F, the safety fall arresters is in non-working state. When the lifting mechanism fails or the lifting wire rope breaks, the safety fall arresters moves freely with the cage. At this time, under the action of the driving mechanism of the safety fall arresters, it drives the transmission mechanism. When the braking force increases to a certain value, the whole system decelerates and finally completes the braking.            

 Use method of fall arresters: When the lifting mechanism or lifting wire rope resumes normal work, the lifting force drives the pulley to move upward, drives the pressure bar to rotate and compresses the spring, thus pulling the sliding wedge back to its original position, completing the reset, and restoring the construction hoist to normal work.
