我厂过去校对回动手把标示板刻度(对百分尺),需要四个起重工和两个调阀工露天作业,多次动车,劳动强度很大,又延长了生产周期,因而成了机车检修中的关键.后来,试用拆摇杆撬十字头来对百分尺,又大大增加了调阀工人的劳动强度.通过学习毛主席著作,调阀工人和技术人员互相结合,经多次试验、改进,终于试验成功了不动轮不撬十字头对百分尺.通过多台车的检验和长期运用,证明它是可靠的.它大大缩短了生产周期,并减轻了劳动强度.现以反修型机车为例说明如下. I calibrate the factory back to the past the calibration board scale (on the scale), the need for four cranes and two valve workers open-air operations, motor car many times, labor-intensive, but also extended the production cycle, which became a locomotive After overhauling the rocker lever pry the crosshead to the scale, but also greatly increased the labor intensity of the valve operator.While studying Chairman Mao’s works, valve workers and technicians combined with each other, after many tests , Improved, and finally succeeded in testing the fixed wheel does not pry the crosshead on the scale. Through the inspection and long-term use of multiple vehicles to prove that it is reliable. It greatly shortens the production cycle and reduce labor intensity. Model locomotive as an example below.
