Precision grading coupler

JG Excavator Hydraulic Wrist has redefined the flexibility limit of railway excavators. This revolutionary hydraulic wrist attachment, with its 270° bidirectional swinging function, endows traditional excavators with unprecedented multi-directional operation capabilities, completely solving problems such as track side wall trimming and precise ditch excavation in narrow spaces. Its integrated hydraulic control system supports continuous angle adjustment, allowing operators to complete complex posture adjustments without frequently moving the machine body, significantly reducing equipment wear and fuel consumption. As a benchmark of excavator swing joint technology, its reinforced sealing structure and shock-resistant design ensure zero-fault operation under continuous vibration and high-load conditions, significantly extending the equipment's lifespan and compressing maintenance costs. It is the intelligent core equipment for modern railway infrastructure.
