Durability 100 years, expansion device, hybrid joint, type 3LII.
A bridge expansion device proven to last 100 years! No replacement needed for new bridges for 100 years! Long-term water-tightness, maintenance-free [NEXCO specification compliant product].
The Hybrid Joint 3LII type has a vertical integrated structure of the load support plate and anchor plate, making it highly durable and preventing damage from metal fatigue. Its durability is equivalent to an ultra-long term of 100 years! It has been proven through fatigue loading tests conducted by a third-party organization, clearing the equivalent of 12 million cycles, which corresponds to 100 years. This assumes that a 25-ton large vehicle has traveled over the 3LII type 12 million times, equating to a 100-year durability. The standard design supply period for bridges is 100 years. For newly constructed bridges, there is no need to replace the expansion device for 100 years. The 3LII type is maintenance-free, eliminating the need for sound inspection that requires traffic regulation, leading to reduced maintenance costs and improved safety. It is a product capable of accommodating large expansion ranges (150-350mm) and wide gaps (up to 730mm), making it one of the largest among expansion devices that have passed NEXCO standards. It has been widely adopted on highways nationwide as a product that meets NEXCO specifications. For more details, please contact us or request a catalog.
