Automatic Cable Tray Roll Forming Machine (50-300mm)
Fully automatic, gantry through-shaft cable tray roll forming machine for producing double arc edge cable trays with a base width of 50–300 mm and a height of 50 mm. The line integrates decoiling, servo leveling & feeding, 180T punching, cutting and 28-pass roll forming into one continuous process — delivering high precision (±1.5 mm), stable output of 5–12 m/min, and minimal labor.
Why Choose This Cable Tray Roll Forming Machine
- Fully Automatic Line — Active decoiler → servo leveling & feeding → punching → conveyor → roll forming → output, all in one pass.
- Double Arc Edge Forming — Specialized 28-pass roll forming produces smooth, burr-free double arc edges on the small side.
- Wide Range 50–300 mm — One machine covers base widths from 50 mm to 300 mm at 50 mm height.
- Heavy-Duty 5T Decoiler — Hydraulic expansion mandrel handles coils up to φ1500 mm OD, 5-ton load capacity.
- High Precision — Length/width tolerance ±1.5 mm, bending angle 90° ± 2°.
- Trusted Components — INVT inverter, Delixi/Chint controls, Harbin bearings, Ruibofeng gearbox.
Product Overview
The 50–300 mm Automatic Cable Tray Roll Forming Machine is a 300-type gantry through-shaft production line engineered for continuous, high-volume manufacturing of steel cable trays with double arc edges. It rolls Q235 cold-rolled steel and galvanized strip from 0.5 mm to 1.5 mm thick into finished trays measuring 50–300 mm wide × 50 mm high, in fixed lengths of 2500 mm.
From raw coil to finished tray, the entire workflow is automated: the hydraulic decoiler feeds strip into an 11-roll servo leveling, punching and cutting integrated unit, then a 180-ton punch processes holes, and the strip passes through the conveyor platform into the 28-pass roll forming section before exiting on the powerless output table.
Forming Process Flow
