Finished Product Inspection Institution of Fall arresters

 The production inspection of safety fall arresters is supervised by the director of the factory. However, our safety fall arrester has also been inspected by the professional department of local City.The pulling force testing experimental center is an independent testing unit. RAMHOIST products are tested by this unit correctly. Only after issuing the inspection safety report can they enter the market.            

 All fall arresters products enforce European standards as follows:            

 The movable fall arresters on the rigid support can automatically lock the movable speed difference fall arresters on the track or rope of the rigid support, and the loose force device can be added.            

 The mobile fall arresters on the soft support can automatically lock the safety fall arresters on the soft support (such as rope) and add the loose object.            

 High-altitude fall arresters rope, connecting material or part of an equipment, it can be made of synthetic fibers rope, metal rope, belt or chain, up to 2 meters long.           

 The control system of this product is made of special steel and treated specially. It is light in weight, wear-resisting, corrosion-resisting and impact-resisting.The shell is made of aluminium alloy, which is light in weight and ageless.            

 Aviation wire rope is selected as safety rope for safety fall preventer. Hanging rope and seat belt are all flame retardant, resistant to high temperature of 200 C, and matched with factory.            

 In view of the safety and reliability of the speed difference fall preventer when it is braked by rope fall preventer, a mechanical model of the tension and relaxation of the brake rope is established for the two cases that the buffer rope of the fall preventer is not pulled out and pulled out. The conditions for the pull-out of the buffer rope, the brake deceleration of the catch device at  the brake rope and the brake rope movement are given. Tension e­xpression.The correctness of brake rope impact mechanics model was verified by field wellhead drop-proof buffer experiment. The critical speed needed to reach the buffer condition of the buffer rope being pulled out and the peak brake deceleration speed at the arrest point of the brake rope were calculated by using the brake  rope impact mechanics model. The results show that the critical velocity decreases with the increase of cage mass or the decrease of the length of brake rope above the catching point, and the peak brake deceleration at the catching point increases with the increase or decrease of the falling speed of the cage. Shock behavior.            

 Reminds you that without the qualified report of the fall arresters, the inspection institution will not issue the inspection report. In the installation supervision and inspection report of the construction elevator, there is a special report for the anti-falling safety device, which must be qualified.           
 First of all: the number of the industrial crash preventer is like an ID card, which has a number. Every manufactured product has a number. The progressive crash preventer is checked once a year, and the inspection report needs to be recorded.    

Secondly, is it necessary for derrick material hoist to have safety regulations for construction of safety differential crash preventer? Even if the site is not supervised from the point of view of our own production safety, it still needs protective measures to do a good job.           

 Again: Is your high-altitude crash preventer tested once a year?            

 Finally: In the decoupling test of the fall arresters, the relative height of the cage to the fall arresters of the brake wire rope is different according to the selected fall arresters. The general requirement is not more than 100 mm, but some fall arresters can reach about 750 mm. RAMHOIST reminds you that choosing safety fall arresters must choose professional weight fall arresters, which is not suitable for civil anti-falling.
