Sany SY55U is a 5.5-ton zero-tail-swing mini crawler excavator. The export Tier3 version is equipped with Kubota V2607 mechanical direct injection engine without urea after-treatment. It has good fuel compatibility and tolerance to low-quality diesel, suitable for overseas markets such as Africa, Southeast Asia and Latin America. It adopts Sany DOMCS load-sensing hydraulic system with well-matched pump and valve, delivering smooth, coordinated combined movements and excellent fuel efficiency. Zero-tail design means the rear counterweight stays within the track width during swing, perfect for narrow alleys, yard renovation, indoor demolition and tight-wall jobs. Standard dozer blade assists backfilling, grading and stabilising the machine. Widely used for municipal trenching, landscaping, farm water conservancy, foundation digging, site leveling, light breaking and indoor demolition. The ROPS/FOPS cab features wide visibility, suspension seat and light control levers. Service points are grouped for convenient ground-level maintenance.
