Bridge Crane Installation Guide – Steps, Tips & Best Practices

Installing a bridge crane is a crucial step in setting up any industrial lifting system. A well-planned and properly executed installation ensures optimal performance, long-term safety, and minimal downtime.

In this guide, Nybon Machinery outlines the key steps, requirements, and tips to help you install your bridge crane correctly, whether you’re working with a single girder, double girder, top-running, or underhung model.

📍 Step-by-Step Bridge Crane Installation Process

1. Site Preparation

  • Ensure the installation area is clean, dry, and level.

  • Verify that runway beams or supporting columns meet load and alignment specifications.

  • Remove any obstructions from the installation zone.

2. Foundation and Runway Setup

  • Anchor runway beams or freestanding support structures.

  • Use a laser level or total station to ensure precise horizontal and vertical alignment.

  • Verify span dimensions and bracket positions before tightening bolts.

3. Bridge Assembly

  • Assemble the main girders and end trucks on the ground.

  • Mount the trolley and hoist as per the manufacturer’s instructions.

  • For double girder cranes, install the trolley rail atop the girders.

4. Lifting and Positioning

  • Use a mobile crane or forklift to lift the assembled bridge into position.

  • Align and bolt the end trucks onto the runway rails.

  • Check for smooth travel along the entire runway length.

5. Electrical Connection

  • Install power supply systems (conductor bar or cable festoon).

  • Connect control panels, hoists, limit switches, and emergency stops.

  • Ground all electrical components to prevent overload and short circuits.

6. Functional Testing

  • Test hoisting, trolley, and bridge travel individually and together.

  • Adjust limit switches for lifting height and end-of-travel limits.

  • Perform load testing (typically at 125% of rated capacity).

✅ Installation Requirements at a Glance

The hoist must match or exceed your maximum lifting requirement. Typical capacities include:

Item Minimum Requirement or Guidance
Runway Beam Alignment Deviation ≤ ±2mm over 10 meters
Bridge Span Accuracy Deviation ≤ ±3mm total span
Power Supply 380V/3Ph/50Hz (standard, customizable)
Grounding Resistance Less than 4 ohms
Load Test Requirement Static test at 125% / Dynamic test at 110% of rated load

🔧 Expert Installation Tips

  • Use anti-loosening fasteners (spring washers or lock nuts) for all mechanical joints.

  • Apply industrial-grade lubricants to rail joints, hoist gears, and moving parts.

  • Mark limit switch activation zones clearly for future adjustments.

  • Always follow national codes like OSHA, FEM, or ISO 12480 for overhead crane installation.

  • Don’t forget to install bumpers, buffers, and end stops on both ends of the runway and bridge.

🏗 Who Should Perform the Installation?

Bridge crane installation should be carried out by:

  • Certified in-house maintenance teams

  • Professional crane installation contractors
