Freestanding Bridge Crane | Single Girder Overhead Crane

Video Introduction of Single Girder Freestanding Bridge Crane

This short video shows an indoor freestanding bridge crane with a single girder top running bridge and a freestanding runway.

The crane runs on its own runway columns and is used to lift and move materials inside workshops, factories, warehouses, and production areas. The electric hoist travels along the bridge girder, while the bridge crane travels along the runway.

The freestanding runway does not need to be hung from the workshop roof. This arrangement is often used where the existing building is not suitable for supporting an overhead crane runway.

Why Use a Freestanding Bridge Crane?

The main reason is simple: the crane has its own runway structure.

A conventional overhead crane may use the building columns or a building-supported runway. A freestanding system uses separate runway columns and foundations.

This can work well when:

• The workshop has no existing crane runway.
• The building structure cannot take the crane loads.
• A new lifting area is being added to an existing workshop.
• Materials need to be moved between fixed workstations.
• The customer wants the crane system independent from the building structure.

The runway layout can be arranged according to the available floor space, crane span, travel distance, and lifting area.

Related Crane Specifications

The final crane size and runway structure are determined from the actual load, span, lifting height, travel distance, operating frequency, and workshop conditions.

What Do You Need to Specify a Freestanding Bridge Crane?

For a preliminary quotation, the following information is normally enough:

A workshop drawing is helpful if the runway columns, foundation locations, or available lifting area need to be checked.

FAQs

1. When should I use a freestanding bridge crane?

Use a freestanding bridge crane when you need an indoor overhead lifting system but do not have a suitable building-supported runway. It is also useful when the crane needs to be kept independent from the existing building structure.

2. What capacity can a single girder freestanding bridge crane handle?

Single girder freestanding bridge cranes are commonly used for loads from 1 to 20 tons. The actual capacity depends on the span, lifting height, operating conditions, and crane duty.

3. How much does a freestanding bridge crane cost?

There is no single price because the runway structure is part of the system. The cost depends on the crane capacity, span, runway length, lifting height, hoist, controls, duty class, and foundation requirements.

For a useful quotation, provide the capacity, span, lifting height, and runway length first.

4. Does the runway need to be connected to the workshop building?

No. A freestanding runway is supported by its own columns. The building and crane runway can therefore be designed as separate structures, subject to the site and foundation conditions.

5. Can the runway be made to fit an existing workshop?

Yes. The runway length, column positions, crane span, and lifting area can be worked out from the workshop layout and the required material handling path.

6. What information should I send for a quotation?

Start with four numbers: lifting capacity, crane span, lifting height, and runway length. Add the power supply and working frequency if available. A workshop drawing is useful for a detailed design.
