HOPEX cable tray joint connector forming machines produce Russian-type perforated trays with the jointing connection formed directly on the production line. At the hydraulic cutting station, the machine cuts to length and swages one end of the tray in the same stroke — creating an integrated joint connector that lets sections telescope straight into one another on site, with no separate splice plate, coupler, or secondary end-forming operation. This is the defining advantage of the Russian tray system: faster field assembly, fewer loose accessories to ship and stock, and a cleaner continuous cable run. Each cable tray joint connector machine covers a 194–814mm feeding width and 1.2–2.0mm rolling thickness, running Q235B cold-rolled, hot-rolled strip steel, and galvanized material on a single line, with a 31-roller progressive forming section synchronized by a Delta / Schneider PLC to hold hole-group spacing and joint-end geometry consistent from the first tray to the ten-thousandth. The full cycle — decoiling, leveling, hydraulic perforation punching, 31-roller forming, and cut-with-swage — runs as one continuous automated process at 380V, with energy-saving hydraulics that lower per-tray operating cost across multi-shift production. Backed by 28+ years of expertise in cable tray manufacturing, every machine ships with a 2-year warranty, machinery test report, video outgoing-inspection, and online technical support.
