This video shows a 1 ton freestanding bridge crane with a top running single girder design.The bridge runs on its own runway, supported by steel columns. An electric hoist is used for lifting and moving materials inside the workshop.
The main reason to choose this type of crane is often the site condition.
Some workshops simply do not have a structure for mounting an overhead crane.The roof may be too light. The existing steel frame may not be designed for crane loads. In some cases, the building cannot be modified.
A freestanding bridge crane solves this by using its own runway and columns.
A freestanding crane does not have to cover the whole workshop.
The runway can be arranged around the actual work area. Column positions can be planned around machines, walls, storage racks, and production equipment.
This works well when only a certain part of the workshop needs overhead lifting.
A factory may not need a full building-length crane.
The requirement may be limited to:
A freestanding bridge crane can be installed over that area without extending the crane system to the rest of the building.
Adding a building-supported crane can involve structural reinforcement and other construction work.
A freestanding system keeps the crane structure separate from the building. The main site check is then the available floor space and the foundation for the columns.

Key Features
This compact datasheet is suitable for quick reference, quoting, and side-by-side comparison with other suppliers.
For this type of crane, the workshop layout is just as important as the crane capacity.
Check:
A simple workshop drawing with the machines and lifting area marked is usually enough to start the layout.
A 1 ton freestanding bridge crane is suitable for light lifting and material handling, including:
It is particularly useful when these loads need to be moved across a work area rather than lifted at one fixed point.
Use one when there is no suitable building support, the building is difficult to modify, or the crane is only needed over a specific work area.
Yes. The runway and column layout can be designed around the available space and existing equipment.
No. The runway is supported by its own steel columns. The floor and foundation still need to be checked for the column loads.
Yes. Freestanding bridge cranes are often used when an existing building needs additional lifting capacity without major structural changes.
Send the load capacity, span, lifting height, runway length, working area, power supply, and a workshop drawing if available.
Yuantai Crane manufactures freestanding bridge cranes for workshops, factories, warehouses, and production areas.
For a 1 ton project, provide the required span, lifting height, runway length, and workshop layout for a suitable crane arrangement.
Overhead Crane Manufacturer with CE, ISO, SGS, CNEX Certificates.
