CABLE SYSTEMS
Grooveless Powerball Design
Eliminates jacket abrasion and cable damage during installation — the most common cause of cable degradation in traditional pulling methods. Cables arrive undamaged, every run.
Corelay — Automated Smart Cable Pulling System
AUTOMATED
CABLE PULLING
TECHNOLOGY
// SYSTEM CAPABILITIES
Eight reasons the automated system outperforms manual cable pulling.
PERFORMANCE
Up to 25 m/min Pull Speed
Sustained automated pulling at speeds impossible to maintain manually — dramatically shortening programme time on large installations. HV, MV and LV cable on cable ladder systems.
CONNECTIVITY
40 Pullers Per Inverter
A single power panel co-ordinates networked automated pullers across the entire cable run simultaneously — no sequential manual repositioning, no crew bottlenecks.
ENGINEERING
Dual-Motor Drive
Each puller uses two motors — delivering superior pulling strength, better stability, and sustained performance on demanding cable ladder runs without force spikes.
PRECISION
Precision Scale Display
Detailed scale display gives both experienced engineers and new operators clear, accurate read-outs of tension, speed and force throughout every pull in real time.
FLEXIBILITY
Adjustable Ball Spacing
Ball spacing adjusted with a standard spanner — rapid reconfiguration between different cable types and ladder geometries on the same project without specialist tooling.
PROTECTION
Reduced Manual Handling
Full automation significantly reduces musculoskeletal strain and injury risk on every run — lowering CDM exposure, fewer operatives required in confined and difficult-access spaces.
DURABILITY
Cable Ladder Specialist
Purpose-built for heavy cable on cable ladder systems — the containment type where automated pulling delivers its greatest advantage. HV, MV, LV across all commercial sectors.

Why Not Just Pull?
A conventional winch accumulates tension along the entire cable run — peaking above 8,000 lbs at the head. Our distributed drive resets tension at every unit, keeping each section under 300 lbs and eliminating snap-back risk entirely.

// PROCESS
Fully Automated. Controlled Tension. Every Pull.
The Corelay system replaces manual effort with precision mechanical automation — reducing installation time, eliminating cable damage, and delivering a consistent, certifiable result on every project.
01
Site Survey & System Configuration
Corelay engineers survey your cable routes on cable ladder systems and configure the automated system for your specific cable type, size and route requirements before mobilisation.
02
Powerball Positioning Through Ladder Containment
Automated pullers are positioned at calculated intervals through the cable ladder. The grooveless Powerball design prevents cable jacket abrasion throughout — eliminating the primary failure point of conventional methods.
03
Fully Automated Pull
Up to 40 pullers per inverter operate simultaneously at speeds up to 25 metres per minute. The system does the work — fewer operatives required, no manual strain, no force spikes that damage cables.
04
Certified Handover
All installations are tested to BS 7671 by our NICEIC-approved engineers. Full certification, EICR reports and test documentation provided — ready for your client handover pack or compliance records.

// PROJECT BENEFITS
What Every Project Gains from the Automated System
Whether you are an electrical engineer, facilities manager, civil engineer or main contractor — the automated system delivers measurable improvements across every critical area of your project.
Faster Programme Delivery
Automated pulling at up to 25 metres per minute means large cable volumes are installed in a fraction of the time — protecting your commissioning and handover dates.
Zero Cable Damage
The grooveless Powerball design maintains cable integrity throughout the full run. No jacket abrasion, no tension spikes — essential for high-specification power and data cabling.
Full Compliance Documentation
Every installation is carried out by NICEIC-approved engineers and certificated to BS 7671. Full EICRs, test certificates and installation records — ready for building control, client audit or compliance frameworks.
Improved Site Safety
Automated operation reduces musculoskeletal strain and incident risk on every run. Fewer operatives required in difficult access situations — directly improving your CDM compliance position.
Protected Project Margin
Lower labour requirement, faster programme, eliminated re-work from cable damage — the automated system protects your margin from the three most common cost overrun sources on large cable installations.
Single Specialist Contractor
Corelay delivers automated cable pulling as part of complete M&E scope — electrical design, fire alarms, security and AOV under one contract. One programme. One point of contact.

// FAQ
Questions About the Automated System
Common questions from electrical engineers, facilities managers, civil engineers and main contractors about Corelay's fully automated smart cable pulling service.
What is Corelay's fully automated smart cable pulling system?
Corelay's fully automated smart cable pulling system is the only system of its kind available in the UK and Europe — Corelay hold exclusive UK and European distribution rights. The system uses networked automated pullers with a grooveless Powerball mechanism to guide cables through cable ladder containment at controlled tension, operating at up to 25 metres per minute with up to 40 pullers per inverter. It is designed for large commercial, industrial and infrastructure cable ladder installations where manual methods are too slow, too risky, or carry too high a risk of cable damage.
Does the system work with HV, MV and LV cables?
Yes — Corelay's automated smart cable pulling system covers all voltage ranges on cable ladder systems — HV, MV and LV — as a single specialist contractor. The system is configured to your specific cable type and size before mobilisation to ensure correct pull parameters throughout the entire run.
Why is cable ladder the right containment type for this system?
Corelay's automated system is specifically engineered for cable ladder installations — where heavy cables on long runs present the greatest challenge to manual methods. Cable ladder is the containment system where automated pulling delivers its most significant advantage: consistent tension control across long runs, minimal cable damage risk, and significantly fewer operatives required versus manual pulling on ladder systems.
Can Corelay subcontract the pull for my existing project?
Yes. Corelay works with electrical contractors, main contractors and M&E companies on a subcontract basis — providing the automated system, trained engineers and full BS 7671 certification on a project-by-project basis. White-label arrangements are available where Corelay operates under your brand and documentation is produced in your company's name. Call 0117 463 2988 to discuss your project.
How does the automated system protect my project margin?
The automated system protects margin in three direct ways: fewer operatives required on the pull (lower labour cost), significantly faster installation on long cable ladder runs (reduced prelims and programme risk), and elimination of cable damage re-work — one of the most expensive cost overruns on large cable installations. Call 0117 463 2988 for a project-specific assessment.
Is all Corelay cable pulling work certified and documented?
Yes. All installations are carried out by NICEIC-approved engineers and certificated to BS 7671. Corelay provides full installation certificates, EICRs and test documentation on every project, backed by a 12-month written workmanship guarantee. Documentation can be produced in formats suitable for your client handover pack, building control, ITP or sector compliance requirements.
What areas of the UK does Corelay cover?
Corelay is Bristol-based and mobilises across the entire UK for large commercial and infrastructure projects. We cover Bristol, Bath, London, Birmingham, Cardiff, Oxford, Reading, Swindon and beyond — wherever your project is located. Call 0117 463 2988 or 03301 331 817 to discuss your location and programme requirements.
