The mobile lifting platform is an indispensable means of transportation in industrial production. It plays an important role in high-altitude operations. With the frequent occurrence of safety accidents in recent years, we should pay more attention to safety. Machinery Co., Ltd. will explain to you the safety performance instructions of the mobile lifting cage
platform. 1. Anti-falling safety device ①The anti-falling safety device is an important part of the lifting platform, and it is necessary to rely on it to eliminate the occurrence of cage falling accidents and ensure the safety of the occupants. Therefore, the factory test of the anti-fall safety device is very strict. Before leaving the factory, the legal inspection unit will measure the torque, measure the critical speed, and measure the spring compression. Each unit is accompanied by a test report and assembled into the construction mobile type. After the lifting platform is mounted, the drop test under the rated load is carried out, and the mobile lifting platform in use on the construction site must be subjected to a drop test every three months. ② The anti-falling safety device that has been delivered for two years (the date of delivery of the anti-falling safety device) must also be sent to the legal inspection unit for inspection and testing, and then tested once a year. Few people have sent for inspection so far, and some construction sites do not even do a drop test every three months, thinking that their anti-fall safety devices are okay, but once an accident occurs, they regret it. Why not regularly test and submit for inspection according to the system? It is good if the user unit blindly thinks that it is not bad. In fact, the quality of the anti-falling safety device can only be judged through testing and inspection. It is impossible to determine whether it is good or bad in daily operation. For those over-duty anti-falling safety devices, it is recommended to submit for inspection earlier and regularly. Experiments are good, and only by knowing what is in mind can we prevent serious accidents before they happen. 2. Safety protection switch The safety protection switches of the mobile lifting cage platform are designed according to safety needs, including fence door limit, cage door limit, top door limit, limit switch, upper and lower limit switch, counterweight anti-break Rope protection switch, etc. In some construction sites, in order to save trouble, some limit switches are artificially cancelled and short-circuited or not repaired in time after they are damaged, which is equivalent to canceling these safety lines of defense and planting hidden dangers of accidents. For example: the hanging cage needs to be loaded with long things, and the hanging cage cannot fit inside and needs to be extended out of the hanging cage, and the door limit or the top door limit is artificially cancelled. When the above-mentioned safety facilities are incomplete or incomplete, people still carry people and things. Illegal operations are joking with human lives. In order to avoid potential accidents, it is hoped that the leaders of the unit will strengthen management, strictly require the maintenance of the mobile lifting cage platform and the operators to regularly check the safety and reliability of various safety switches to prevent accidents. 3. Timely replacement of worn gears and racks. Construction on the construction site. The working environment is harsh. Cement, mortar and dust cannot be eliminated. The gears and racks are ground each other, and the teeth are still in use after they are sharpened. Attract attention. As we all know, the tooth profile should be like a cantilever beam. When worn to a certain size, the gear (or rack) must be replaced. To what extent should you stop using it and replace it with a new one? It can be measured with a 25-50mm common normal micrometer. When the common normal length of the gear is worn from 37.1mm to less than 35.1mm (2 teeth), it must be replaced with a new one. gear. When the rack is worn, measured by the tooth thickness caliper, when the chord height is 8mm, the tooth thickness is worn from 12.56mm to less than 10.6mm. The rack must be replaced. However, many 'old teeth' gears and racks move on the construction site. The type lifting platform is still overdue. For safety reasons, new parts must be replaced. Summary: While the elevator manufacturer guarantees that it is qualified to leave the factory, the operators should also operate rigorously and rationally. They must not be indifferent, safety is no small matter, and the incidence of safety accidents should be reduced to a minimum.
