Overhead bridge barriers, also known as gantry bridges or gantry spans, have been responsible for significant bridge collapse incidents in recent years, resulting in substantial losses and shocking scenes. The causes are primarily due to overweight and over-dimensional loads, bridge design and construction, and bridge supervision and maintenance.
The original role and function of overhead guardrails have undergone a significant change and expansion, with their basic function extending from protecting bridges and tunnels to safeguarding roads. The quality of overhead guardrails has rapidly upgraded from small and light to large and heavy. Moreover, in addition to the bridge authorities uniformly setting up overhead guardrails, there has even been a phenomenon of private and excessive installation of such guardrails by social units. Overhead guardrails are not a magic charm to control overloaded vehicles from entering bridges, nor are they a one-size-fits-all solution. How to reasonably set up and manage overhead guardrails is a matter that deserves in-depth consideration by relevant departments.

Currently, China has not yet issued unified regulations for the establishment and management of road and bridge height restrictions in urban areas. The relevant departmental standards are also relatively outdated, such as the "Code for Design of Urban Road Engineering" (CJJ37-2012 technical specification), approved and implemented by the Ministry of Housing and Urban-Rural Development of the People's Republic of China on May 1, 2012. This specification clearly stipulates the road clearance, with the minimum clearance for motor vehicle lanes being 4.5 meters. For roads used by trolleybuses, tramways, double-decker buses, and other special vehicles, the minimum clearance should meet the requirements for vehicle passage.

Product Description
The gantry span can reach up to 36 meters. Gantry towers can be set up on both urban roads and highways, used for hanging traffic signs and billboard advertisements, installing surveillance video equipment mounts, and mounting LED highway information boards. The reasonable advantages of the gantry include hot-dip galvanized or painted components, offering excellent rust resistance. Gantry towers can be quickly installed on-site, minimizing impact on traffic flow. They are known for their good rust resistance, strong wind resistance, reasonable load capacity, diverse design styles, stable installation, and competitive pricing. They are widely used in road facilities such as general highways, expressways, and railways.
