Gantry Crane Selection Guide: 7 Key Factors to Consider Before Purchase

Introduction

Gantry cranes are versatile lifting solutions used across industries for outdoor and indoor material handling. Unlike overhead cranes that require building support, gantry cranes have their own support structure, making them ideal for yards, construction sites, shipyards, and facilities without existing runway systems.

At SUNFACRANE, we manufacture a full range of gantry cranes tailored to diverse applications. Here are the 7 key factors you must consider before purchasing a gantry crane.

1. Determine the Gantry Crane Type

Single Girder Gantry Crane

Double Girder Gantry Crane

Semi-Gantry Crane

Truss Gantry Crane

  • Lightweight truss structure for large spans with lower deadweight
  • Cost-effective for outdoor applications with long spans
  • Common in precast concrete yards and construction sites

2. Define Your Lifting Capacity

Gantry cranes range from 1 ton to over 900 tons. Your capacity requirement depends on the heaviest load you need to handle. Always include a safety margin of 15-25% to account for dynamic loading during lifting and travel.

3. Measure Your Span Requirements

The span is the distance between the two legs of the gantry crane. This is determined by the width of the area you need to cover. Common spans range from 7.5m to 40m, with wider spans achievable through custom engineering.

4. Calculate Required Lifting Height

Lifting height is the vertical distance from ground level to the hook at its highest position. Consider:

  • The height of the load itself
  • The height of any rigging equipment (slings, spreader beams)
  • Clearance needed to safely maneuver the load

5. Assess Work Duty Classification

Your operational intensity determines the required work duty:

  • A3-A4: Occasional use, maintenance applications
  • A5: Regular use in general manufacturing and warehousing
  • A6-A7: Heavy use in shipyards, steel yards, and precast plants
  • A8: Continuous severe duty

6. Evaluate the Operating Environment

  • Outdoor use: Requires weather protection, corrosion-resistant paint, and windproof anchoring systems.
  • Coastal/marine environments: Need enhanced anti-corrosion treatments.
  • High temperature areas: Require special heat-resistant components.
  • Explosive atmospheres: Must have explosion-proof certifications.

7. Choose Control and Safety Systems

  • Pendant control: Simple wired controller for basic operations.
  • Radio remote control: Provides operator mobility and improved safety.
  • Cabin control: For large cranes requiring operator visibility from height.
  • Safety features: Overload protection, limit switches, anti-collision systems, rail clamps, and anemometers for outdoor cranes.
