Container Gantry Crane Core Product Types

• 1. Rubber-Tired Gantry Cranes (RTGs):

  • تصميم: Mobile cranes running on rubber tires, typically diesel-electric or electric (via cable reel or conductor bar). Feature a towering gantry structure spanning multiple container stacks.

  • Application: The workhorse of container storage yards. Used for stacking containers, loading/unloading trucks, and transferring containers to/from other handling equipment like reach stackers or straddle carriers.

  • Key Weihua Features:

    • High Maneuverability: Ability to move freely within yard lanes.

    • Wide Span: Accommodates multiple container rows (على سبيل المثال, 6+1, 7+1 truck lane configurations).

    • Lifting Capacity: Typically ranging from 30.5t to 50t (under spreader), often up to 60t for heavy lifts.

    • رفع الارتفاع: High stacking capabilities (على سبيل المثال, 1-over-5, 1-over-6).

    • Power Options: Diesel-electric (common), Full Electric (cable reel/conductor bar), Hybrid (diesel + battery storage).

    • Automation Ready: Designed for easy integration with automation systems (Auto Steering, Auto Positioning, Container Identification).

• 2. Rail-Mounted Gantry Cranes (RMGs):

  • تصميم: Fixed-path cranes running on dedicated ground rails. Can be single-girder or double-girder designs.

  • Application: Ideal for high-density, long-term container storage yards, intermodal rail terminals (loading/unloading rail cars), and areas requiring precise, high-volume stacking over defined paths.

  • Key Weihua Features:

    • High Stability & Precision: Excellent positioning accuracy due to fixed rails.

    • High Lifting Capacity & فترة: Capable of spanning very wide areas (multiple rail tracks and container stacks) and handling heavy loads.

    • Efficiency in Density: Superior for stacking containers very high (1-over-7 or more) over large areas.

    • Power Options: Primarily Full Electric (conductor bar/slip ring systems).

    • Automation Focus: Highly suitable for fully automated operation (Automated Stacking Cranes – ASCs).

Container Gantry Crane Technical Specifications Overview

Weihua Container Gantry Crane Key Advantages & Technologies

• 1. Robust & Durable Construction:

  • High-strength steel (Q345B/C/D or equivalent international standards).

  • Optimized structural design (box girder or truss, depending on model/span) using FEA analysis for maximum strength-to-weight ratio.

  • Critical components (wheels, bearings, gears) from renowned international suppliers (SKF, FAG, Siemens, ABB, Schneider, etc.) or high-quality Weihua-manufactured alternatives.

  • Advanced anti-corrosion treatment (sandblasting, multi-layer painting) for harsh port environments.

• 2. Enhanced Productivity & Efficiency:

  • High-Speed Hoisting & Travel: Optimized drive systems for faster container moves.
  • Precise Control: Sophisticated AC variable frequency drives (VFDS) for smooth acceleration, deceleration, and pinpoint load positioning.
  • Telescopic Spreaders: Standard 20’/40′, often with options for 45′, twin-lift (2×20′), or even tandem-lift capability.
  • Container Identification Systems (CIS): Optional integrated optical character recognition (OCR) for automatic container number detection.

• 3. Advanced Safety & Automation:

  • Comprehensive Safety Systems: Overload protection, anti-collision systems (between cranes, with trucks), anemometers & wind alarms, emergency stops, limit switches, safety interlocks.
  • Anti-Sway Control: Sophisticated algorithms to minimize load swing during travel, improving safety and efficiency.
  • Remote Control: Option for cabin-less operation via remote control stations.
  • Full Automation Solutions: Weihua provides complete ASC solutions with Auto Steering, Auto Positioning, Container Pick & Place logic, Traffic Management System (TMS) integration, and Crane Management System (CMS).

• 4. Operator Comfort & Ergonomics:

  • Spacious, ergonomic, and climate-controlled cabins with excellent visibility.

  • Intuitive control interfaces (levers, touchscreens).

  • Low vibration and noise levels.

• 5. Environmental Responsibility:

  • Electric & Hybrid RTGs: Significantly reduce diesel consumption, noise, and CO2/NOx/SOx emissions compared to traditional diesel RTGs.
  • Regenerative Drives: Capture energy during lowering/braking and feed it back into the system (for electric/hybrid models).
  • Efficient Electric RMGs: Zero local emissions.

• 6. التخصيص & Global Support:

  • Tailored Solutions: Cranes are engineered to meet specific customer requirements regarding span, lifting height, capacity, stacking capability, power source, automation level, and site conditions.
  • Global Network: Extensive sales, service, and spare parts network supporting installations worldwide.
  • Lifecycle Support: Installation, commissioning, operator training, preventive maintenance programs, repair services, and technical support.
