Elektryczny wciągnik linowy

W instalacjach urządzeń elektroenergetycznych, produkcja kabli i transport ciężkich materiałów, the hoisting of large cable drums, transformers or steel coils is a core part of high-risk, high-precision operations. Traditional lifting equipment can easily cause load swings, inaccurate positioning and even equipment damage. The electric cable hoist developed by Grupa Weihua specifically for this scenario combines precision control technology, enhanced structural design and industry-specific functions to redefine the safety and efficiency standards for heavy-duty coil handling.

Why do the world’s leading cable manufacturers choose Weihua hoists? (5 core technical advantages)

1. Industry customized spreader system

• Adaptive drum lifting beam: V-shaped saddle + adjustable clamp arm design, perfectly fits cable drums/steel coils of different diameters (Φ1m~Φ4m), eliminating the risk of slipping.

• Rotating hook (360° continuous rotation): supports precise direction adjustment of the cable drum in the air to avoid damage caused by flipping on the ground.

• Anti-flattening protection: The pressure sensor monitors the force on the hanging point in real time to prevent thin-walled coils from deforming (fakultatywny).

• Quick change interface: compatible with C-type hooks, electromagnetic disks and other accessories, switching hoisting mode within 5 minutes.

2. Intelligent anti-shake and millimeter-level positioning

• Weihua i-Swing intelligent anti-sway system:

  • Active damping control based on AI algorithm, swing suppression ≥90% during start/stop.

  • Laser positioning + encoder feedback to achieve ±1mm repeatable positioning accuracy (suitable for docking narrow shelves/trucks).

• Dual Speed/Variable Frequency Control Options:

  • Normal mode: 0~20m/min (efficient handling)

  • Micro movement mode: 0~1m/min (precise shaft threading, equipment in place)

3. Heavy-duty durable structural design

• FEM-M8 working level: higher durability than industry standard (M5), suitable for high-intensity continuous operations.

• Reinforced wire rope system:

  • Anti-rotation rope core + zinc-nickel alloy coating (anti-wear and corrosion resistance).

  • The double spiral groove design of the drum prevents random rope hopping.

• Hot-dip galvanizing or spray anti-corrosion: suitable for harsh environments such as acid fog in cable factories and outdoor substations (C4 protection level).

4. Multiple security mechanisms

• Dual brake redundant system: main brake (released when powered on) + backup mechanical brake, locked instantly when power is off.

• Zabezpieczenie przed przeciążeniem (110% alarm, 125% power off): prevent overload damage to the structure.

• Limit triple protection: 1. Mechanical striker limit (forced cut-off); 2. Rotary encoder soft limit; 3. Absolute sensor redundancy check.

• 24V safety voltage control circuit: avoid the risk of electric leakage and injury (CE/ISO13849 certification).

5. Energy efficiency optimization and intelligent IoT

• IE4 high-efficiency motor + regenerative braking unit: feedback grid energy saving, energy consumption reduced by 30%.

• Optional Weihua cloud monitoring system:

  • Real-time monitoring of load, motor temperature rise, and operating times.

  • Predictive maintenance reminders (rope life/brake pad wear).

  • Mobile APP remote fault diagnosis.

Core application scenarios of electric cable hoists (solution examples)

Sprawa 1: Intelligent transfer of high-voltage cable drums

• Pain point: The cable drum with a diameter of 3.2m and a weight of 32 tons needs to be loaded accurately, and manual hooking takes 30 minutes.

• Weihua plan:

  • 32 tons electric cable hoist + adaptive hanging beam.

  • I-Swing anti-sway system achieves ±5mm loading positioning.

  • Efficiency improvement: single lifting time ≤8 minutes.

Sprawa 2: Substation transformer installation

• Pain point: Precision equipment is placed in a narrow foundation pit (swaying can easily hit the wall).

• Weihua plan:

  • 50-ton low-headroom hoist + millimeter-level micro-movement mode.

  • Dual camera hook visualization system.

  • Successful case: ±0.5mm error completed 500kV transformer in place.

Sprawa 3: Cable factory production line linkage

• Pain point: The coil needs to be automatically connected to the pay-off machine.

• Weihua plan:

  • Custom orbital Wciągnik elektryczny system.

  • Synchronized control with PLC to achieve fully automatic loading.

  • RFID identifies coil specifications and automatically adjusts the spreader.

Często zadawane pytania

Q：What is the difference between an electric cable hoist and an ordinary overhead crane?

A：The core difference lies in the dedicated spreader + precyzyjna kontrola:

① Standard coiled material adaptive lifting beam (not ordinary lifting hook).

② Anti-shake accuracy is more than 5 times higher.

③ Reinforced structure to meet frequent full load operations (FEM-M8 level).

Q：Can an existing crane be retrofitted into a cable-specific hoisting system?

A：Can! Weihua provides:

• Retain the main beam structure and replace the lifting mechanism.
• Install i-Swing intelligent anti-sway module.
• Matching custom spreaders (2 weeks delivery).
  The modification cost is only 40%~60% of the new machine.

Q: How to protect the outdoor cable yard?

A：Recommended configuration:

• IP65 protection level (rain and dustproof).
• Motor resistant to -25°C low temperature (cold zone).
• Stainless steel control box + anti-salt spray coating (coastal working conditions).

Q：How to prevent the insulation layer from being scratched when lifting the cable drum?

A：Key measures:

① Use nylon-coated slings (not in direct contact with steel wire ropes).

② Add a polyurethane cushion pad to the suspension beam saddle.

③ Micro movement mode controls landing speed ≤0.3m/min.
