From Oct. 1 to Oct. 5, through careful organization and scientific arrangement, the project quickly improved the quality of Zoomlion Heavy lifting hook passing shot blasting machine, including replacing 16 newly designed shot blasting machines, remaking the installation groove and re arranging the position, adjusting the angle of the shot blasting machine, and replacing the Mn steel chamber body guard board. On the premise of not affecting the company's production, we rush to work day and night (5 days and 5 nights, almost all night overtime), and complete the company's requirements with quality and quantity guaranteed. After the completion of the project, the shot blasting effect of the shot blasting machine is good, the noise is low, the operation is stable, the shot blasting effect is excellent, and the final transformation purpose is achieved.
