HOPEX-Cable Tray Roll Former
Tooling is where a cable tray roll former either holds its section for years or starts drifting after the first big order. This page sets out what is fitted and why.
| Attribute | Specification |
|---|---|
| Number of rows | 26 rows |
| Material | 45# steel, quenched and hard chromed |
| Design basis | According to the profile drawing |
Quenching gives the body strength to resist deformation under load. Hard chroming adds a surface that resists the abrasion of galvanized and Zn-Al-Mg coatings. Neither treatment alone covers both requirements.
| Attribute | Specification |
|---|---|
| Diameter | 70 mm solid shaft |
| Construction | Solid |
| Material | 45# steel, tempered |
The shaft is not a wear surface; it is a beam. Tempered 45# steel gives the toughness and fatigue resistance a rotating beam needs, where a fully hardened shaft would be more brittle.
Strip runs 0.8 – 1.5 mm. On thin gauge the risk is flange buckling rather than springback, so 26 rows are used to keep each bend increment small.
| Section | Configuration |
|---|---|
| Decoiler | electric decoiler, 10 t maximum loading |
| Levelling | 12-roller leveller with lifter linkage system |
| Punching | two-position punching machine |
| Hydraulics | Two solenoid valve sets, #46 hydraulic oil |
| Drive | 7.5 KW × 3 main motors |
These are the components covered by the 2 years warranty.

| Weight | 50000 kg |
| Main motor | 7.5 KW × 3 |
| Installed capacity | about 50 KW |
| Supply | 400 V ±5%, 60 Hz |
| Origin | Tianjin, China |
| Free maintenance | 18 months |
Q1. What are the rollers made from?
45# steel, quenched and hard chromed.
Q2. Why is the shaft only tempered, not hardened?
The shaft works as a rotating beam. Tempered 45# steel gives toughness and fatigue resistance; a fully hardened shaft would be more brittle.
Q3. How many forming rows are there?
26 rows, designed according to the profile drawing.
Q4. What shaft diameter is used?
70 mm solid shaft.
Q5. Which components are covered by warranty?
Engine, PLC, gearbox, gear, pump, bearing, motor and pressure vessel, for 2 years.
Q6. Can tooling be made for our own tray profile?
Yes. Roller design follows your profile drawing.
