Heavy Mining & Stone Excavation Flagship

Hiyo HY235H-SA is a 23-ton heavy-duty medium excavator tailor-made for mining and hard stone construction sites, equipped with reliable Isuzu 4HK1 National IV engine and Kawasaki HOPE full electronic control hydraulic system. It delivers 158kN bucket digging force with a large 1.35m standard bucket, and an optional rock bucket is available for severe rock stripping and ore excavation. The intelligent urea injection system optimizes fuel combustion to cut operation expenses, while upgraded hydraulic circuits reduce power loss and lift work efficiency. With 51kPa ground pressure and 70% climbing capacity, the machine runs stably on slippery mine slopes and rugged quarry ground. Compact swing design enables flexible operation in narrow underground mining roadways. The fully optimized C12 cabin with 10-inch WLAN touch screen eases operator fatigue during long-hour mining shifts. This multi-functional digger fits earthwork, stone, open-pit mine and municipal engineering, earning consistent praise from global mining contractors for strong power and low failure rate.

Automated Production Workshop for Hiyo HY235H-SA Heavy Digger

Hiyo builds exclusive large standardized workshops for heavy medium excavators, equipped with independent dedicated assembly lines for HY235H-SA 23-ton crawler excavators. The workshop adopts robotic automatic welding, precision CNC machining and digital hydraulic assembly processes to control component matching accuracy strictly. Core engine and hydraulic components are inspected one by one before assembly to avoid hidden quality risks. Each assembly station arranges full-time quality inspectors to track tightness of hydraulic pipelines and structural welding joints. After assembly, all finished machines pass 3-hour continuous heavy-load running tests to check digging force, traveling and rotary stability. Clean, orderly production environment reduces assembly errors, supporting stable mass shipment of HY235H-SA to fulfill global bulk heavy machinery orders on schedule.
