CABLE BUNDLING MACHINES FOR SUBSEA CABLE LAYING
Double & Single Thread Bundling Systems · Continuous Laying · Vessel & Land-Based Use
AVAILABLE FOR ORDER · NEW BUILD UNITS
Purpose-built cable bundling machines for simultaneous subsea cable laying. Thread is wound around the cables to keep them together during lay and burial. Designed for continuous production, automatic speed matching to cable feed, and safe deck installation. Both machine types are standalone and require only power and secure fastening to the deck.

3. Single Bundling Machine — Details
Bundles multiple cables by applying 1 to 4 nylon threads during simultaneous lay. Prevents spreading on the seabed so the cables can be buried together. Also suitable for repair of already-laid cables and for land-based pre-bundling.
Key Specifications
| Item | Specification |
|---|---|
| Function | 1–4 nylon threads around several cables at once |
| Typical use | 2 power cables, or 1 power + 1 fibre (or more); repair of laid cables |
| Direction | Bi-directional (forward and reverse) |
| Speed | 0 – 30 m/min; automatic start and speed regulation according to cable movement |
| Motor | 2.2 kW with frequency transformer 0.25 – 4 kW |
| Power supply | 1-phase, 16 A, 230 V ~ |
| Overall size (H × W × D) | 1 950 × 1 300 × 1 070 mm |
| Centre height | 1 300 mm |
| Weight | Approx. 870 kg |
| Tread rolls | Max weight 10 kg; max OD 270 mm; min ID 32 mm; max length 310 mm |
| Operation | Starts automatically when cable moves through the machine |
| Installation | Standalone unit – must be securely fastened to vessel deck (or used on land) |
| Documentation | FAT recommended before deployment; operating guidance provided at FAT |
