Selecting the correct tonnage of a truck crane is essential for the success of any lifting project. The tonnage determines the crane’s maximum lifting capacity and directly affects safety, efficiency, and overall project costs. Selecting the right crane ensures stable operations, minimizes downtime, and helps prevent unnecessary expenses.

What Does the Tonnage of a Truck Crane Mean?
The tonnage of a truck crane refers to the maximum rated lifting capacity of the crane, measured in metric tons. It is based on specific working conditions, typically with the boom fully retracted and the load close to the crane’s centerline. As the boom extends or the working radius increases, the lifting capacity decreases. Understanding the load chart of a crane is essential for safe operations. For example, a 25-ton truck crane can lift 25 tons at a 3-meter radius but only 10 tons at a 20-meter radius.
Factors Influencing the Right Tonnage Selection
When selecting the appropriate tonnage of a truck crane, consider the following:
- Maximum Lifting Weight
Estimate the heaviest load the crane will handle and add a 20–30% safety margin. - Working Radius and Boom Length
The lifting capacity decreases with distance; consult the crane’s load chart. - Project Type
Small municipal projects: 8–25 tons
Medium industrial projects: 25–80 tons
Large infrastructure projects: 80–200 tons - Site Conditions
Soft or uneven ground requires cranes with wider outriggers or higher stability. Environmental and spatial constraints also affect selection.
Typical Applications by Tonnage
| Tonnage of Truck Crane | Typical Applications | Project Type | Advantages |
|---|---|---|---|
| 8–16 tons | Light material handling, street maintenance | Municipal / Urban | Compact, high mobility, fuel-efficient |
| 20–25 tons | Small bridge work, utility installation | General construction | Versatile, easy to operate |
| 30–50 tons | Power station installation, mid-sized industrial | Industrial / Rescue | Stable, strong lifting power |
| 80–200 tons | Bridges, large prefabricated components | Infrastructure | High lifting capacity, advanced hydraulics |
Why Choosing the Right Tonnage Matters
Properly selecting the tonnage of a truck crane ensures:
- Safety: Prevents tipping and structural damage.
- Efficiency: Reduces repositioning and operational delays.
- Cost-Effectiveness: Avoids unnecessary fuel and maintenance costs.
How to Determine the Ideal Tonnage
- Determine maximum load weight (e.g., 10 tons)
- Measure lifting radius (e.g., 12 meters)
- Check the crane’s load chart for suitable models
- Add a 25% safety margin → Recommended tonnage = 12.5 tons → select a 16-ton crane
This method guarantees safe and efficient operations.
