Expandable device "Hybrid Joint 3LIIA type (with guide plate)"
By shaping the steel plate into a guide plate type, it prevents damage to the main body of the grader due to expansion and contraction in snowy areas.
The Hybrid Joint 3LIIA type has a vertical integrated structure for the load support and anchor plate sections, making it highly durable with almost no damage from metal fatigue. By using steel plates vertically, the exposed areas are minimized, resulting in very low impact during operation and making the product less prone to noise and vibration. It is capable of accommodating large expansion and contraction (200–600mm) and wide gaps (up to 1230mm). 【Features】 ○ Supports large expansion and contraction and wide gaps ○ High watertightness due to double sealing structure ○ Long-term durability and maintenance-free For more details, please contact us or request a catalog.
