Cast iron expansion device with snow removal grader-compatible guide plate that can be installed within the pavement thickness! [NETIS registered product] Space-saving installation series (for snow-prone areas)

The "Hinodakutairu Joint α (SCVJ Type)" is a bridge expansion device made of cast iron, designed to achieve a durability equivalent to 30 years through unique casting technology (suitable for snowy regions). It is a steel load-bearing type that can be installed within the thickness of the pavement (cut depth of 80mm) without removing the existing deck slab. This device accommodates the installation on thin deck slabs of small to medium-sized bridges, which could only be addressed by conventional materials or butt-type rubber joints. In addition to the guiding plates arranged on the side of the product body, a sloped shape to prevent grader collisions has been added to the top surface of the body. These two structures mitigate the impact during grader collisions from all angles. 【Features】 ■ Can be installed within the pavement thickness (cut depth of 80mm) ■ No need for special equipment arrangements ■ Achieves a durability equivalent to 30 years through unique casting technology ■ Protection of waterproof materials with load-bearing plates and dustproof materials ■ High waterproofing at the connection surfaces ■ Applies a slip-resistant structure developed for manhole covers ■ Minimal change in slip resistance values ■ Mitigates impacts from grader snow removal vehicles ■ NETIS registered product (QS-210051-A: Space-saving expansion device) *For more details, please refer to the PDF document or feel free to contact us.
