Double Girder Bridge Crane Key Features & 장점

• 1. Unparalleled Load Capacity & 기간:

  • Designed to handle extreme loads (ranging from 20 tons to 500+ tons and beyond) with ease.
  • Capable of traversing longer spans efficiently and safely due to its inherently rigid twin-girder design.
  • Ideal for large bays, wide manufacturing halls, and outdoor gantry applications.

• 2. Superior Structural Rigidity & 안정:

  • Two parallel main girders provide immense resistance to bending and twisting under heavy loads.
  • Significantly reduced deflection compared to single girder cranes, ensuring precise load positioning and enhanced safety.
  • Stable platform minimizes load sway, improving operator control and safety.

• 3. Optimized Hook Height:

  • The trolley and hoist run on top of the girders, maximizing the available hook height beneath the crane.
  • Crucial for facilities with limited headroom or requiring deep lifting into pits or furnaces.
  • Allows for greater vertical utilization of your building space.

• 4. Enhanced Durability & Long Service Life:

  • Robust construction using high-grade steel (typically ASTM A36 or equivalent) withstands harsh conditions, high temperatures, corrosive environments, and intensive usage (FEM 오전 1시, 2중, 3m classes).
  • Designed for demanding duty cycles and continuous operation.

• 5. Greater Flexibility & 다재:

  • Ample space between girders allows for easy integration of auxiliary equipment like walkways, service cranes, lighting, cable trays, magnet panels, or specialized lifting attachments (움켜잡다, spreaders, 등.).
  • Accommodates multiple trolleys or specialized hoists for complex handling tasks.

• 6. 정밀제어 & Maneuverability:

  • Available with smooth and precise variable frequency drive (VFD) control for both bridge travel and trolley motion, enabling soft starts/stops and accurate positioning.
  • Choice of pendant control (wired) or advanced radio remote control for optimal operator safety and visibility.

• 7. 고급 안전 기능 (기준 & 선택 과목):

  • Overload Limit Switches: Prevent lifting beyond rated capacity.
  • 비상 정지 버튼: Instantly halt crane operation.
  • Bumpers/End Stops: Absorb impact at runway ends.
  • 청산 방지 시스템: For multi-crane installations.
  • Crane Travel Limit Switches: Prevent over-travel.
  • Fail-Safe Brakes: On hoist, 트롤리, and bridge drives.
  • 산책로 & Ladders: For safe inspection and maintenance (often standard).

• 8. Reliable Drive Systems:

  • High-torque motors and heavy-duty 크레인 기어박스 designed for industrial environments.
  • Precision-machined end trucks with double-flanged wheels ensure smooth, true travel along the runway beams with minimal drift.

Double Girder Bridge Crane – Technical Parameter Table

Key Notes on Parameters:

• 1. All Values are Indicative: Exact specifications are engineered to order based on:
  • Specific load diagrams & usage patterns.
  • Building/runway structure details.
  • Environmental conditions (먼지, heat, 약).
  • Required duty class (FEM/CMAA).
  • Local safety regulations.
• 2. VFD Control: Strongly recommended for all motions (감아 올리기, 트롤리, Bridge) for smooth acceleration/deceleration, precise positioning, reduced mechanical stress, and energy savings.
• 3. Duty Class is Paramount: Selecting the correct FEM or CMAA class ensures the crane is robust enough for its intended number of lifts, load spectrum, and operating hours, directly impacting longevity and safety.
• 4. Hook Height is Critical: Double girder design maximizes 크레인 후크 키. Accurate measurement from the runway rail top to the floor (and any obstructions) is essential.
• 5. Runway Quality: Crane performance and longevity heavily depend on a perfectly level, straight, and aligned runway system built to appropriate structural standards.
• 6. Certification: Cranes typically require third-party inspection and load testing (예를 들어, 125% of SWL) before commissioning and periodically during service life.
