Technical Requirements for 10T Single-Girder Gantry Crane

The following outlines the Technical Requirements for a 10T Single-Girder Gantry Crane, compiled based on search results. It integrates performance parameters, structural design, safety standards, and intelligent trends, citing relevant technical standards and market data to ensure professional and practical specifications.

1. Basic Parameter Requirements

1. Rated Lifting Capacity: Main hook 10 tons, auxiliary hook can be optionally configured as needed (e.g., 3T or 5T).
2. Duty Class: A3 (moderate frequency of use) or A5 (higher frequency, suitable for frequent operation scenarios).
3. Span Range: Standard span is 7.5-30 meters, non-standard spans can be customized (e.g., 6.5-25.5 meters). The cantilever length should not exceed one-third of the span.
4. Lifting Height: Standard 6-9 meters, maximum customizable up to 30 meters (e.g., for freight yards or docks).

2. Core Performance Indicators

1. Electric Hoist Parameters
   • Model: CD10t or MD10t (dual-speed type), hoisting speed 7 m/min, traveling speed 20 m/min.
   • Motor: ZDY21-4 type travel motor, with power matched according to load.
2. Gantry / Trolley Travel Speed
   • Gantry Speed: 20-38.7 m/min (variable frequency speed control optional to reduce energy consumption and noise).
   • Trolley Speed: 20 m/min (standard) or 30 m/min (high-speed custom option).
3. Operating Environment
   • Temperature Range: -25°C to +40°C, suitable for outdoor or indoor operation.
   • Power Supply: Three-phase AC 380V / 50Hz.

3. Structural Design and Materials

1. Main Girder Type
   • Welded combination girder using U-shaped channel plate and I-beam (standard design), or aluminum alloy main girder (lightweight solution, reducing weight by 30% and enhancing corrosion resistance).
2. Drive Unit
   • The gantry uses an integrated three-in-one drive, combining motor, brake, and reducer for a compact structure.
3. Rail Requirements
   • Gantry rail model P38. Regular correction of deviation is required (recommended inspection every 3 months).

4. Safety and Compliance Requirements

1. Safety Devices
   • Essential devices include hoisting height limiters and travel limiters to ensure automatic power cut-off upon exceeding limits.
   • Wire rope wear monitoring (regular inspection cycle ≤ 3 months).
2. Applicable Standards
   • Compliance with Crane Terminology (GB/T 6974.1-2008) and Technical Conditions for Wire Rope Electric Hoists (JB/T 9008.1-2014).
3. Special Equipment Certification
   • When the rated lifting capacity is ≥ 3t and the lifting height is ≥ 2m, special equipment operation certification (Q2 category) must be obtained.

5. Intelligence and Maintenance

1. Intelligent Control
   • IoT connectivity function is optional, supporting remote monitoring and fault warning.
2. Maintenance Cycle
   • Comprehensive inspection every 3 months, including electrical connections, rail levelness, and steel structure welds.

6. Optional Configurations and Customization

1. Operation Mode: Cab operation or ground remote control.
2. Additional Functions: Variable frequency speed control, anti-sway system, audible and visual alarm devices.

The above technical requirements synthesize current industry standards and technological innovation trends. Parameters can be adjusted according to actual application scenarios (e.g., factories, docks, hydropower stations). For further non-standard customization (such as extra-long spans or adaptation to extreme environments), consultation with the manufacturer based on specific working conditions is necessary.
