Crane Electrical Cable

VOITTO Crane supplies heavy-duty industrial crane electrical cables engineered for continuous power transmission and precise control signaling in harsh material handling environments.

  • Rated Voltage: 300/500 V to 0.6/1 kV
  • Operating Temp: -40 °C to +90 °C
  • Copper Stranding: Class 5 / Class 6

VOITTO Crane supplies a full range of crane electrical cables for power and control: crane festoon cable, flat crane cable, reeling cable for gantry crane cable reel systems, and drag chain cable. Built to IEC, VDE and CE requirements, every cable is designed for the constant travel of an eot crane cable system and for oil, dust, heat and outdoor exposure. Custom lengths, core counts, and sheath materials are available on request.

Product Description

Crane electrical cables are responsible for transmitting power and control signals to the traveling trolleys, hoisting mechanisms, and suspended control devices on overhead and gantry cranes. During operation, these cables must not only withstand thousands of bends per shift and continuous tensile loads but also cope with environments contaminated with oil or dust; at the same time, they must ensure the stable transmission of signals for variable frequency drive (VFD) systems and suspended control circuits. VOITTO takes these demanding operating conditions fully into account when manufacturing every cable.

VOITTO Technical Highlights

  • This structure uses fine, multi-strand conductors made of 99.99% oxygen-free copper, which comply with VDE 0295 / IEC 60228 Class 5 and Class 6 standards and offer excellent resistance to flex fatigue.
  • Built-in stress-relief structure: Tensile loads are absorbed by a core consisting of two galvanized steel wires or Kevlar (aramid), thereby protecting the copper conductors from tensile stress.
  • The jacket is made of PUR (polyurethane), NBR (nitrile rubber), or PVC (polyvinyl chloride) and offers oil resistance, abrasion resistance, and UV resistance.
  • The design features a tangle-resistant and strand-break-resistant structure, and a torsion-balanced stranding process ensures cable stability.
  • Conductors are color-coded or numbered for quick wiring, troubleshooting, and replacement.

Types of Crane Cables

All types of cranes require cables whose geometric design and mechanical strength are appropriate for their specific application. VOITTO offers four main categories of cables: drag chain cables, drum cables, flat cables, and suspended cables. Please select the appropriate cable based on travel distance, operating speed, and available installation space.

Crane Drag Chain Cable

crane drag chain cable

Round, torsion-resistant cable for energy chains (towline systems) with fast, repeated bending. Its low-bend-radius construction keeps copper stress low at high travel speeds.

Key Features:

  • Bending radius as low as 7.5×D
  • Anti-torsion layered cabling process
  • Oil- and abrasion-resistant PUR or NBR sheath
  • Optional dense copper-braid shield (EMC) against VFD interference

Compatible Crane Types: European standard single and double girder EOT cranes, automated storage cranes, cleanroom cranes and precision assembly shop cranes.

Flat Crane Cable

flat crane cable

Flat Crane Cable uses parallel, in-line cores for compact installation space and single-direction high-flex bending. Hanging runs stay tidy, with no twisting between loops.

Key Features:

  • Bending radius about 40% smaller than a round cable of the same specification
  • Multi-layer stacking without tangling or knotting
  • Optional self-supporting galvanized steel wire ropes on both sides for pendant or long vertical spans
  • Cold-resistant NBR or special PVC sheath

Compatible Crane Types: General single girder and double-girder cranes, workshop jib cranes, electric hoists, and pendant control station cables that travel with the crane.

Gantry Crane Cable Reel

gantry crane cable reel

VOITTO covers both sides of gantry crane cable reel demand: heavy-duty round reeling cable built for repeated winding and dragging, and matching spring-driven, motorized, and hysteresis (magnetic coupling) gantry crane cable reel units. Order the Heavy-Duty Reeling Cable alone or as a complete Cable Reel System.

Key Features:

  • Central high-strength Kevlar (aramid) or galvanized steel wire strain element
  • Double sheath of tear-resistant, weatherproof PUR or neoprene (CR)
  • Withstands long-distance, high-tension winding and ground abrasion
  • No bulging and no core breaks in service

Compatible Crane Types: Outdoor rail-mounted gantry cranes (RMG), rubber-tyred gantry cranes (RTG), shipyard gantry cranes, grab gantry cranes, and magnet cranes (long-travel reel power supply).

Crane Festoon Cable

crane festoon cable

Crane festoon cable is a power and control cable for C-track, I-beam, and wire-rope festoon systems, in flat and round hanging versions. It is designed for the repeated folding of trolleys along the run.

Key Features:

  • Withstands repeated trolley folding and gathering impact
  • Weather- and aging-resistant for dusty, hot indoor shops and outdoor temperature swings
  • Color- or number-coded cores for quick maintenance wiring
  • Supplied as a complete set: cable, festoon trolleys and track

Compatible Crane Types: Heavy-duty double-girder EOT cranes, foundry cranes (optional silicone high-temperature type), port bridge-type handling cranes, and long-span workshop power supply lines.

FAQ

How do I choose between a flat crane cable and a round reeling cable?

Choose a flat crane cable for compact festoon runs, pendant cables and single-plane bending, where stacked folding and a smaller bend radius matter. Choose round reeling cable for repeated winding on a reel, dragging and multi-directional tension. Send travel length, speed and installation method, and we will confirm the type.

Do you supply complete gantry crane cable reel systems and festoon trolleys along with the cables?

Yes. VOITTO supplies complete gantry crane cable reel systems (spring-driven and motorized), festoon trolleys, C-track and end clamps together with matched cables.

Which eot crane cable is recommended for VFD (inverter-driven) cranes?

For inverter-driven cranes, use a shielded drag chain cable, or a screened flat or festoon cable with dense copper braid. The shield reduces VFD electromagnetic interference on control and encoder signals, and grounding at both ends protects signal stability.

What is your minimum order quantity and lead time for custom crane cables?

MOQ depends on cable type and customization level. Contact VOITTO with your specification for an exact quotation.

Crane Electrical Equipment: Control Systems, Limit Switches & Safety Devices Explained

Crane electrical equipment refers to every component that powers motion, regulates travel, and enforces safety limits across a crane system — including control stations, limit switches, contactors, overload relays, and emergency protection devices. Without a properly integrated electrical system, even a structurally sound crane cannot operate safely or predictably. Procurement managers sourcing overhead cranes or gantry cranes often evaluate structural specifications in detail — span, lifting capacity, duty class — while treating the electrical system as a secondary checklist item. This is a costly mistake. Electrical failures account for a significant share of crane incidents, most of which trace back to undersized protection devices, improperly set limit switches, or control systems mismatched to the application. This guide explains what crane electrical equipment consists of, how each subsystem works, and what questions to ask your supplier before accepting any configuration. What Crane Electrical Equipment Actually Covers Crane electrical equipment is best understood as three functional layers that work together: the control layer (how operators command movement), the power and drive layer (how motors receive and regulate electricity), and the protection layer…
