When a building has limited space, a standard crane layout is not always possible. ONVALLA offers two solutions for these cases: the underslung crane, which is installed together with the building structure, and the electric overhead side crane, a special design that extends outside the building to lift loads in.
What Is an Underslung Crane?
An underslung crane is a crane that can be installed together with the structure of the building. It can be built as a single-girder or double-girder crane, depending on the customer’s needs.
Advantages:
- No additional columns are needed, because the crane is carried by the existing building structure.
- Higher lifting height than other crane types.
What Is an Electric Overhead Side Crane?
The Electric Overhead Side Crane is a crane specially designed by ONVALLA Co., Ltd. Its key advantage is that it can extend out of the building to lift a load from below and bring it inside. When it is not in use, it slides back into the building so the doors can be closed normally.
Which One Fits Your Building?
| Need | Suitable solution |
|---|---|
| No room for new columns, and maximum hook height | Underslung crane |
| Loads arrive outside the building and must be lifted in | Electric overhead side crane |
Frequently Asked Questions
Can an underslung crane be double-girder?
Yes. It can be built as single-girder or double-girder, depending on the customer’s requirement.
Does the side crane block the building doors?
No. When it is not in use, it slides back inside the building, and the doors can be closed normally.
Both solutions depend on the building’s structure, so a site survey comes first. Explore ONVALLA’s crane range or contact our engineers.
