At the end of July, Shanghai set off the third wave of high temperatures this summer, and this wave of high temperatures was menacing and full of firepower. Compared to the previous two rounds of high temperatures, this wave will last longer and be more intense.
In the repair workshop of the third bus company, under the trench, on the roof of the bus, and in the compartment, the two-hundred-pound tires with wheels are pushed to be replaced, and the wrenches are flexibly rotated between the nuts...... A group of maintenance workers are fighting on the front line, their arms are stained with oil, and they are sweating and responsible to ensure the safe operation of city buses.
In order to ensure ventilation and safety, air conditioning cannot be installed in the repair workshop. As soon as I walked in, although I didn't expect the heat wave to hit my face, I only stayed for a while, and I felt the temperature rise sharply, and I was sweating profusely within a few minutes. The maintenance workers in the repair workshop of the third bus company have long been accustomed to such a working environment, and they are still engrossed in overhauling the vehicles.
Jin Yuxi is a veteran employee of the team, and after checking the tires, he walked to the second floor. "We have to go up to the coal station to check the roof, because it is a tram, so the coal essence (carbon brush of the collector pole, which has the effect of allowing the 'whip' to collect electricity) and the collector pole are required to be inspected." Fastening the safety rope and putting on the hard hat, Jin Yuxi and his colleagues climbed onto the roof of the car, because it was close to the roof, it was not as ventilated as the first floor, and the heat surging upwards, Jin Yuxi often joked that he was like a steamed bun in a steamer, and he was about to be "cooked". "Generally, vehicle maintenance takes more than an hour, and it doesn't take too long to encounter a small breakdown. In addition, the vehicle breakdown rate will increase relatively in summer, so we must be more careful and not let go of any hidden danger. Getting off the roof of the car, Jin Yuxi was already soaking wet, and the sweat on his forehead fell down the bridge of his nose.
In order to ensure that the vehicles can be put into operation on time, Jin Yuxi and his colleagues are often busy for several hours. In response to the high temperature, the three bus companies equipped the repair workshop with electric fans and ice cubes to cool down, and provided heatstroke prevention and cooling supplies, providing them with "logistical support".
It is these maintenance workers who accurately correct every value to the standard value and tighten every screw to ensure the safe travel of citizens.
