重庆升降平台的变速部分和锥鼓式限速器的离心制动部分，是封闭式的，其他部分是开启式的。封闭部分不易检查，现场只能看一下变速箱是否漏油．锥鼓式限速器名牌上标注的检测日期是否过期。锥鼓式限速器必须经有法定检测资质的安全，检测机构定期检测并做铅封，使用单位不准随意调整。
Centrifugal brake part shifting part of Zhejiang and freight elevators cone drum speed limiter is closed, the other part is on style. Closed portion is not easy to check whether the site can only look at the gearbox oil leak. Cone drum speed limiter date marked on the nameplate detect whether expired. Cone drum must be approved by the governor has the statutory safety testing qualification, periodic testing and testing organizations do seals, are not allowed to be adjusted using the unit.
升降平台开启部分的检查与检测不同，因安全检查涉及的点多面广，时间有限，相对于的安全检测要粗放一些。一般情况下不带仪器，全凭经验观察：主要检查各传动部位的间隙不能过大，一般控制在0.2～0.5mm左右，齿轮与齿条吻合时齿底的间隙为2.0mm。啮合间隙过大或齿轮齿条磨损严重都是很危险的，货梯的运行和制动力都要通过齿轮齿条传递。啮合深度不够、磨损严重或轴向错位过大，都会使啮合面积减小而造成齿轮齿条强度降低，发生断齿事故，在实际安全检查过程中发现。
Inspection and testing different parts of Zhejiang freight elevator opened, due to security checks involving over a broad area, limited time, with respect to the safety testing freight elevator to the extensive number of Zhejiang. Under normal circumstances without instruments depends on empirical observations: the gap is mainly check the transmission parts can not be too large, generally controlled at about 0.2 ~ 0.5mm, consistent with the rack gear tooth bottom clearance for 2.0mm. Backlash is too large or badly worn gear rack is very dangerous, running and braking Zhejiang freight elevator must pass through the rack and pinion. The depth of engagement is not enough, badly worn or axial dislocation is too large, will make the engagement area is reduced causing the rack and pinion strength decreases, the occurrence of the accident broken teeth, was found in the actual security check process.
检查过程中应注意导轮与齿条的间隙不应太大，一般在0.2～0.5mm，滚轮与导轨的间隙也要控制在0.2～0.5mm，电梯运行应该平稳，无异响，无明显的震动。
Zhejiang freight elevator inspection process should pay attention to the guide wheel and rack space should not be too large, generally 0.2 ~ 0.5mm, the wheel and the rail gap should be controlled at 0.2 ~ 0.5mm, the elevator should be smooth, no abnormal sound, no significant vibration.
