RTG Crane Installation Guide: Key Steps for Safe and Efficient Setup

Introduction

The Rubber Tyred Gantry (RTG) crane is widely used in ports, precast yards, and heavy industries due to its mobility, high capacity, and flexibility.

However, installation quality directly impacts safety, performance, and lifespan.

This guide outlines the complete RTG crane installation process, key technical points, and common issues—helping buyers and engineers ensure a smooth setup.

1. Pre-Installation Preparation

Proper preparation ensures safe and efficient installation.

Site Requirements

• Flat, reinforced ground with sufficient load capacity
• Clear working area for lifting operations

Equipment & Tools

• Heavy-duty cranes (100T+)
• Torque wrenches, laser alignment tools
• Safety equipment (harness, barriers, grounding)

Component Inspection

• Verify all parts (structure, wheels, hoist, hydraulic system)
• Check for damage or missing items

2. RTG Crane Installation Process (Step-by-Step)

---

Step 1: Gantry Structure Assembly

• Install A-frame legs and main girder
• Align verticality (≤1/1000 deviation)
• Control diagonal error ≤5mm

👉 This step determines overall structural stability

---

Step 2: Traveling System Installation

• Install wheel sets and axles
• Align wheel parallelism
• Connect drive system (motor or hydraulic)

👉 Ensures smooth, trackless movement

---

Step 3: Auxiliary Structures & Safety Systems

• Install platforms, railings, and cabin base
• Add wind anchors and anti-fall protection

👉 Improves operational safety

---

Step 4: Electrical & Hydraulic System Setup

• Install control cables and PLC system
• Connect sensors (load limiter, encoder, wind meter)
• Install hydraulic pipelines and test pressure

👉 Ensures precise control and stable operation

---

Step 5: Testing & Commissioning

• No-load test
• Load test (50%, 100%, 125%)
• Check braking, deformation, and system response

👉 Final step before delivery

3. Key Safety & Quality Control Points

Structural Safety

• Perform non-destructive testing (NDT)
• Ensure proper bolt tightening and anti-loose measures

---

Electrical & Hydraulic Protection

• Grounding resistance ≤4Ω
• Clean hydraulic system to prevent contamination

---

On-Site Safety

• Certified operators only
• No lifting under strong wind conditions
• Use proper rigging with safety factor ≥6

---

4. Common Problems & Solutions

Gantry Misalignment

• Cause: uneven ground or incorrect positioning
• Solution: recalibrate using laser alignment tools

---

Crane Travel Deviation

• Cause: wheel misalignment or uneven load
• Solution: adjust axle parallelism and tire pressure

---

Hydraulic Leakage

• Cause: loose connections or seal failure
• Solution: tighten fittings or replace seals

---

Conclusion

RTG crane installation is a critical step between manufacturing and operation.

A proper process ensures:

• Stable performance
• Long service life
• Safe operation
