On November 22, the city of daqing, heilongjiang province, after a heavy snowfall, was covered in snow and covered in snow. Technical expert liu forward is facing the cold, in the field to help a wind power company to carry out the construction of broken bolts.

This time, two M36 bolts were broken in the blade link part, which should be quite easy for Mr. Liu, who had successfully treated the same size bolts in the same part a month ago. However, due to the low temperature in the field, the tools, especially the alloy bit, have reduced toughness and become brittle, and the low-temperature fatigue fracture has occurred for many times in the process of construction. At the same time, it was dark early, and the sun set at 4pm.

Bolt broken blade is the second blade during the fan installation. If it is not installed, the subsequent third wind blade will not be installed, and on-site equipment and logistics units will be stuck at the construction site, causing a large number of personnel and cost losses.

Construction units can only temporarily shut down. In order to remove the bolt as soon as possible, help the construction unit to reduce the loss. In spite of the fierce wind, master liu successfully removed the hinge bolt after 1 day's hard work, and the second bolt has completed most of the construction work. Due to serious wear and tear, liu completed the rest of the work smoothly in the morning of the 23rd. Amid cheers from construction crews, wind power construction continued.

In the past two years and more, the experts in the bolt project department have traveled all over the country, from kunming in the south to daqing in the north, from lanzhou in the west to kunshan in the east, without any failure, making contributions to the wind power industry.
