Jinan Changhao High-Performance Hydraulic Quick Hitch is precision-engineered for 20-ton class excavators. Our coupler allows operators to switch between buckets, hydraulic breakers, and grapples in under 30 seconds without leaving the cab. Designed to match the high-pressure breakout forces of machines like the Caterpillar 320, Sany SY215, and Komatsu PC200, this quick coupler is the ultimate productivity booster for demolition and mining job sites.
