Single-suspension Unidirectional Support

Single-suspension unidirectional support is the most compact and cost-effective unitized solution in mechanical and electrical seismic support systems. Comprising a single suspension rod and a unidirectional seismic diagonal brace assembly, it provides vertical suspension and single-direction horizontal seismic restraint for lightweight cable trays, single pipes, or small air ducts. product simplifies structure to the maximum while meeting basic seismic requirements, reducing material and installation costs-making it an affordable, widely applicable option for auxiliary pipeline systems in compact spaces with light loads and clear seismic direction needs.

The structural core of Single-suspension unidirectional support is "single-point suspension + unidirectional restraint." The single rod bears all vertical pipeline loads, anchoring securely to the building ceiling via seismic hinges or C-shaped channel connectors. The unidirectional diagonal brace-usually an adjustable rigid strut-connects to the rod near the pipe clamp and anchors to the lateral structure at a 30-45 degree angle, forming a triangular force transmission path. Due to its single-point suspension and unidirectional restraint, its load-bearing capacity and seismic coverage are limited, so it is strictly used for secondary or terminal pipelines with verified light loads and minimal vibration. Installation requires precise alignment of the brace with the primary seismic force direction.

Product is ideal for the terminal sections of lightweight cable trays (e.g., lighting and low-voltage systems), small single pipes (DN100 or below), and lightweight air duct straight sections. It excels in extremely confined spaces like pipeline mezzanines or utility corridors, filling gaps where large supports cannot be installed. Offering unparalleled cost-efficiency, space-saving design, and quick installation, Single-suspension unidirectional support meets mandatory seismic standards for eligible pipelines, serving as a flexible, scalable foundation for complex seismic systems.
