Product description
Anti falling safetydevice is a construction of the lift on important component, to rely on it to eliminate the cage fall accidents occurred, to ensure the life safety of the passengers. Therefore, anti falling safetydevice factory test was very strict, before leaving the factory by the statutory inspection unit of torque measurement, critical speed measurement, measurement of the amount of compression spring, each is accompanied by test report, assembled to a construction elevator after under the rated load drop test, and site of the lift must be every three months to a drop test. The factory two anti falling safetydevice of anti falling safetydevice of ex factory date), must also be sent to the statutory inspection unit testing, after testing once a year. So far there are few inspection, some sites even every three months a drop test and don't do, that their anti falling safetydevice no problem, but once out of the accident to regret it. Why not according to the system of periodic test and inspection? Use the unit to think not bad even good. Actually anti falling safetydevice of good or bad is only through the test and inspection to determine whether good or bad, daily operation is unable to determine whether it is good or bad, to those extended service of anti falling safetydevice, recommendations or earlier inspection and periodic tests only accomplish know fairly well to malignant accident nip in the bud.
Safety switch for elevator is according to the need for the design of the security, threshold of the fence, cage threshold, forehead limit, the limit switch, upper and lower limit switches, for weight control rope breaking protection switch etc.. Some site in order to save some limit switch position artificially cancelled and the short connecting or damaged is not timely repair, is equal to the cancelled the security line of defence, hidden dangers of accidents. Cases: cage to load from east to west, in the suspension coop not need to extend out of the hanging cage, and man-made cancel threshold or forehead limit, in case the safety facilities imperfect or incomplete, still carrying people and objects, the exercise of violate the rules and regulations is to take life joking, in order to avoid the hidden dangers of accidents occurred, hope using the unit leadership to strengthen management, strict request a lift maintenance and operation of the safety and reliability of the staff to periodically check the various kinds of safety devices, to prevent accidents from happening.
Wear replacement of gears and racks
Site construction, operation conditions are harsh, cement, mortar, dust impossible to eliminate clean, mutual grinding of gear and rack, tooth wear tip up, still in use, should pay attention to. As is well known, the tooth shape should be like a cantilever beam, when the wear to a certain size, must replace the gear (or rack). How much will the wear be stopped using the replacement? 25-50mm law line micrometer can be used to measure, when the gear base tangent length by 37.1mm wear to less than the size of the 35.1mm (2 teeth) must to replace the new gear. When the wear of the rack, by the measurement of tooth thickness calipers, chord height of 8mm tooth thickness from 12.56mm wear to less than 10.6mm rack must change. However, on the site of a lot of old-fashioned gear rack lifts still in extended service, for the sake of safety must replaced with new parts
