Product Features & Applications
Material & Process Upgrades： 1.Made of high‑strength Q355 low‑alloy steel, with yield strength significantly higher than ordinary carbon steel. 2.High‑temperature quenching process combined with hot‑pressing one‑shot forming technology greatly enhances the hardness of the steel. 3.Features a seven‑reinforcing‑rib design that evenly and efficiently distributes the concentrated load from the cable bolt across the entire tray surface. Work Efficiency Improvement 1.The circular tray can be installed directly at any angle – no angle adjustment required. 2.The circular design has no sharp edges, making it easy to stack and transport. Lightweight with High Load Capacity 1.Stable load‑bearing capacity of over 700 kN. 2.Lower individual weight directly reduces workers' physical labor and improves the overall efficiency of support operations.
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.
