Lifting platform gears, rack replace worn on the construction site, the job harsh environmental conditions scissor lift platform, cement, mortar, impossible to eliminate dust and clean hydraulic lifting platform for mutual grinding, gear and rack, hydraulic lifting platform (3 Zhang) teeth are sharpened still in use, should pay attention to. As we all know, the tooth should be like a cantilever, when worn to a certain size, you must replace the gear (or rack). Wear to what extent we should stop using it to replace the new one? 25-50mm normal line can be used to measure micrometer, when normal length gear worn to less than 35.1mm by 37.1mm size when (two teeth) it must be replaced with new gear. When the rack worn by tooth thickness caliper, chord when 8mm thick tooth wear from less than 10.6mm to 12.56mm, the rack must be replaced, but the site a lot of "old-fashioned" gear, rack lifts extended service still in use, for security reasons, must be replaced with new parts.
