A rope used to protect the safety of people and objects during work at height, usually a synthetic fiber rope, twine or wire rope. It is suitable for similar work such as outside electricians, construction workers, telecom workers, and wire repairs during construction, installation, maintenance, etc. Hastelloy 3.00ml/rev Gear Pump Filling Oil Transfer Dose Gear Pump,Mini Leakage Free Dose Gear Pump,Micro Magnetic Water Gear Pump,Magnetic Transmission Drive Gear Pump Suzhou Macxi Fluid Technology Co.,Ltd. , https://www.macxipump.com
Safety rope features and use strength, wear resistance, durability, mildew resistance, acid and alkali resistance, simple and light.
Instructions for use: Every time you use the safety rope, you must make a visual inspection. During the use, you should also pay attention to the inspection. Test it once in half to one year, and the main parts are not damaged. If it is found that there is damage and deterioration, it will be reflected and stopped in time to ensure safe operation.
The safety rope must be inspected before use. It is found that the damage is stopped and the activity clamp is fastened when worn. It is not allowed to touch open flames and chemicals.
The safety rope is always kept clean. After use, it should be stored properly. After it is dirty, it can be washed with warm water and soapy water in the shade. It can't be soaked in hot water or sunburned.
After one year of use, a full inspection is carried out, and the used 1% tensile test is taken out, and the parts are not damaged or majorly deformed (the test may not be used again)
Safety ropes are protective equipment that prevents workers from falling from high places. Because the greater the height of the fall, the greater the impact, so the safety rope must have the following two basic conditions:
(1) Must have sufficient strength to withstand the impact of the human body when it falls;
(2) It can prevent the human body from falling to a certain extent that can cause injury (that is, it should be able to improve the human body before this limit, and the position will not fall down). This condition needs to be explained again. When the human body falls down from a height, if it exceeds a certain limit, even if the person pulls the rope, the impact force is too large, and the internal organs will be damaged and died. For this reason, the length of the rope should not be too long and there must be a certain limit.
Safety ropes are usually evaluated for strength in terms of strength, namely tensile strength and impact strength. The national standard requires that the tensile strength (limit tension) of the seat belt and its string members must be greater than the longitudinal tension caused by the weight of the human body in the direction of the fall.
The impact strength of the safety ropes and accessories is required to withstand the impact strength, and must be able to withstand the impact of the human body falling in the direction of the fall. Generally, the magnitude of the impact force is mainly determined by the weight of the faller and the distance of the fall (ie, the impact distance), and the fall distance is closely related to the length of the safety rope lanyard. The lanyard is long, the impact distance is large, and the impact force is also greater. The theory proves that the human body will be injured by the impact of 900kg. Therefore, the length of the safety rope lanyard should be limited to the shortest range while ensuring operational activities.
The national standard sets the rope length of the safety rope to o. 5—3m. If the seat belt is suspended at a high altitude, the rope length is 3m, and the weight of 84kg falls. The impact load can reach 6.5N, and the impact damage is still about one-third of the impact, which can ensure safety.
