This tool estimates tray self-weight from material density and an approximate metal volume. For solid and perforated trays, it treats the tray as a formed sheet: Developed sheet width per meter: Dev = W + 2H + 2R Metal volume per meter: V = Dev × t × 1 × (1 − Open%). Estimate cable tray self weight quickly for planning and procurement accurately. Export results instantly for schedules, submittals, and field checks. Density values are typical engineering references. In this guide, we'll walk you through the step-by-step process for calculating cable tray weight, while providing examples for both channel trays and ladder trays. Classification of Loads Cable tray loads can be classified into the following categories: Dead Load (G): This. Both width and the height of tray are functions of the number, size, spacing and weight of the cables in the tray. Load rating is independent of width.
