The Shimmy Reduction of the Arm Frames of Crawler Dynamic Compactors Technique developed by XCMG’s Research Institute has successfully endured 10,000 reliability tests recently; the amplitude of swing of the arm frame following unhooking of pounder has displayed superiority to the benchmark products and thus managed to achieve a leading position in the sector. Further, as the technique has been applied to XCMG’s Dynamic Compactor XGH600, XGH460 and XGH350, the operating stability of a complete machine has been improved substantially, leading to a sales volume exceeding RMB ￥10 million. 

The issue of large amplitude range of swing of the arm frame following unhooking of pounder has contributed to increasing failure rate of weak components including hydraulic system and electrical system. To tackle the issue, the XCMG Research Institute has pioneered globally the Shimmy Reduction of the Arm Frames of Crawler Dynamic Compactors Technique based on particle damping and established Standard One of its performance testing; thus, an analytical approach to the dynamics of complete machine of dynamic compactors has been developed. Consequently, following the application of the technique, the amplitude range of swing of the arm frame has been reduced by 35.6 % and the swinging displacement at rear end of rotary table has been reduced by 62.5%, remarkably breaking through the industry barriers and achieving a leading position in the sector. 

Through validation performed by users in the areas of construction work performance, operating performance, driving performance, safety and reliability, XCMG Crawler Dynamic Compactors has been well received by its customers for its stability, great comfort during operation and low failure rate of the easily damaged parts, living up to its reputation of being Super Sturdy.
