Performance Parameter Comparison

Type Name Material Specification (mm) Self‑weight (kg) Weight comparison vs. conventional tray Load capacity (kN) Load capacity comparison vs. conventional tray
Conventional cable bolt tray — Q235 300×300×16 11.3 — 600 —
Five‑pointed star cable bolt tray — Q355 φ300×10 5.4 lower by 52% 650 increase by 8%
Seven‑pointed star cable bolt tray — Q355 φ300×8 4.5 lower by 60% 700 increase by 16%

Summary

With an innovative structure featuring seven reinforcing ribs, this seven‑pointed star tray achieves a 60% reduction in self‑weight compared with conventional cable bolt trays of the same specification, while its load‑bearing capacity is increased by over 16%. This directly lowers material procurement costs. Its circular design makes it suitable for automated operations, reducing installation time per bolt by 30%, improving construction efficiency, and lowering labor costs. Its service life is more than twice that of traditional trays.
