PUR Hoisting Cage Control Cable with Central Suspension Unit 300/500 V
This heavy-duty control cable is designed for vertically suspended hoisting cages and crane systems exposed to high tensile and mechanical loads. Its movement-optimized bundled construction, central aramid suspension unit and abrasion-resistant PUR outer sheath support reliable operation in demanding indoor and outdoor lifting applications.
Key Highlights
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.
Recommended for power, control and monitoring circuits in vertically moving hoisting equipment where the cable must carry its own suspended weight.
Typical applications include:
- Hoisting cages in crane systems
- Port and container-handling cranes
- Vertical lifting equipment
- Industrial elevators and lifting platforms
- Suspended control stations
- Heavy-duty material-handling systems
- Outdoor lifting machinery
- Applications requiring high tensile strength and controlled cable storage
The reference construction supports up to approximately 50 m of freely suspended cable based on a fivefold safety calculation. Final suspended length depends on the cable construction, installation method, dynamic load and safety requirements.

Finished dimensions, cable weight, tensile capacity and maximum suspended length must be confirmed against the approved production drawing and installation calculation.
THE FACTORY
BEHIND EVERY METER
Founded in 2007 in Foshan, Guangdong, Hulk Electric has grown from a regional producer into a globally recognised manufacturer of customised industrial cable solutions. Our 10,000㎡ facility runs on Toyota Production System lean principles, operated by 150+ skilled professionals producing over 300,000 metres every month.
Every cable you see on this page — including the HK-TRVV series — is engineered, extruded, tested, and shipped from that single facility. No trading company sits between you and the extrusion line.
Source Factory
Direct manufacturer — no middlemen, no markups. You deal with the engineers who run the line.
Deep Customization
Conductor, shielding, jacket compound, colour coding, certification — built to your exact spec.
7-Day Sampling
Rapid samples for new specifications. 15-day lead time on standard production orders.
Global Compliance
35+ certifications covering UL, CE, TÜV, IEC, RoHS and REACH for every major market.
BEFORE YOU ORDER
For stocked configurations listed in the ordering table, MOQ is 100 metres per specification. Custom configurations — non-standard core counts, jacket colours, or special compounds — carry a 500 metre MOQ. Samples of 5–10 metres are available free of charge for qualification testing.
Use shielded (P or PP suffix) whenever the cable runs alongside servo drives, VFDs, or inverters, or when carrying encoder, sensor, or analogue signals. Unshielded is suitable for pure power distribution and simple on/off control lines. If in doubt, our engineering team can review your cabinet layout and advise — this is included with any quotation.
Yes. Send us the existing part number or a sample and we will produce a cross-reference specification with matching electrical, mechanical, and dimensional characteristics. Most cross-references are turned around within 3 working days, with a physical sample following within 7 days.
Standard shipments include the CE Declaration of Conformity, RoHS and REACH statements, and the batch test report. UL Recognition (UL 2464 / UL 20549) is available on request for North American projects — specify this at the quotation stage as it affects the material specification.
Standard configurations ship in 15 working days from order confirmation. Custom-engineered specifications typically require 20–25 working days, depending on compound availability. Rapid sampling for new specifications is 7 days. We will confirm the exact date in writing with your order acknowledgement.
