Heavy-Duty Castings for Construction and Earthmoving Equipment
Construction equipment eats castings: undercarriage parts grind through abrasive ground, hydraulic housings hold pressure while the machine twists, and counterweights simply have to weigh what the balance calculation says they weigh. The material logic here is unforgiving — gray iron for mass, ductile iron wherever shock and fatigue meet, quenched and tempered steel where abrasion decides service life. Heavy sections are where naive gating shows up as internal shrinkage, so first articles on thick parts are qualified by sectioning or ultrasonic testing before the pattern goes into production.
Typical Construction Machinery Parts
- Track rollers, idlers and sprockets
- Final drive and gearbox housings
- Hydraulic valve blocks and cylinder heads
- Counterweights with cast-in lifting bosses
- Boom brackets, links and pivot yokes
- Bucket teeth and replaceable wear parts
Why Choose Us
Heavy equipment castings fail in the field, not in the lab. We qualify thick sections by sectioning or ultrasonic testing before a pattern enters production, and match wear-part hardness to the actual abrasion the machine sees rather than to the biggest number on a datasheet.
