How to Choose the Right Crane Capacity
Three Factors That Determine the Capacity You Need
- Maximum load weight: the starting point, but not enough on its own.
- Lifting radius (horizontal distance): the further the load is from the crane’s base, the lower its lifting capacity at that distance — shown in each model’s load chart.
- Required lift height: determines the boom length needed, which in turn affects the actual available capacity at that distance.
In other words: a “50-ton” crane does not lift 50 tons from any distance or height — that figure is the maximum capacity only at the shortest lifting radius.
Guideline Table by Project Type
| Project Type | Suggested Capacity |
|---|---|
| Small to medium residential and commercial projects | 25 tons or 35 tons |
| Medium-sized construction projects | 50 tons |
| Industrial projects and heavy structures | 75 tons |
| Major projects and long-range loads | 100 tons |
This table is an approximate guide based on common use cases — the exact capacity required depends on load weight, lifting radius, and height together, not weight alone.
Information Worth Preparing Before You Request a Crane
- The approximate weight of the heaviest load
- The approximate horizontal distance between the crane’s position and the load’s position
- The required lift height
- Site conditions (space for crane positioning, ground type)
Conclusion
Don’t rely on load weight alone when choosing a crane — give our team the weight, lifting radius, and required height, and we’ll help you determine the right capacity and model for your project. Browse all available crane capacities from 25 to 100 tons.
FAQ
Is the advertised crane capacity fixed at any distance?
No, the maximum advertised capacity (such as 50 tons) only applies at the shortest lifting radius — actual capacity decreases as the load moves further from the crane base.
What information does your team need to recommend the right capacity?
The approximate load weight, the horizontal distance between the crane and the load, and the required lift height.
Does rental include a qualified driver and operator?
Yes, the crane comes with a driver and a qualified operator as part of the rental service.
