Construction speed of cable tray hoisting

The construction speed of cable tray hoisting depends on tray length, support spacing, hoisting method, and crew efficiency, typically ranging from 20 to 50 meters per day for standard industrial installations.Factors Affecting Hoisting SpeedTray Length and Type: Standard cable trays come in lengths of 12, 20, 24, and 30 feet, with some manufacturers offering up to 40 feet . Longer trays reduce the number of joints and splice plates, which can increase hoisting efficiency, but require more careful handling and lifting equipment. Support Spacing: Short-span trays are supported every 6–8 feet, intermediate spans every 10–12 feet, and long spans 14–20 feet . Wider support spacing reduces the number of attachment points, speeding up installation, but may require heavier-duty trays to maintain structural integrity. Hoisting Equipment: Using cranes, hoists, or pulley systems significantly affects speed. Manual lifting is slower and more labor-intensive, while mechanized hoisting allows multiple trays to be lifted and positioned simultaneously. Installation Complexity: Horizontal and vertical bends, T-pieces, and crossovers require additional alignment and fastening time . Straight runs are faster to hoist and secure. Crew Experience: Skilled crews familiar with standards such as IEC 61537 and BS EN 61537 can install trays more efficiently while maintaining safety and compliance .Practical Speed EstimatesSmall indoor installations: 20–30 meters per day, using manual hoists and short-span trays.Medium industrial installations: 30–40 meters per day, with intermediate spans and mechanized hoisting.Large-scale or long-span installations: 40–50 meters per day, using cranes or powered hoists for long trays and minimal supports .Tips to Optimize Hoisting SpeedPre-assemble tray sections on the ground to reduce time at height.Use longer trays where feasible to minimize joints and splice plate installation.Plan support locations in advance to avoid delays during hoisting.Coordinate multiple crews for simultaneous lifting and fastening.Follow standards (IEC 61537, BS EN 61537, NEMA BI 50015/50016) to ensure safety and reduce rework . By considering these factors, project managers can estimate realistic hoisting speeds and optimize labor and equipment allocation for cable tray installations.
