Underhung Overhead Crane

Applications of Underhung Overhead Crane

Underhung overhead cranes are widely used in workshops, factories, warehouses, and production facilities where floor space must be kept clear or where a traditional top running crane structure is not suitable. They are especially useful for light to medium-duty material handling and localized lifting operations.

Machinery Workshops

In machinery workshops, underhung cranes are used to lift and move machine parts, tools, molds, motors, gearboxes, and semi-finished components. They help improve internal logistics and reduce manual handling.

Assembly Lines

Underhung overhead cranes are suitable for assembly stations and production lines. They can be installed above work areas to move components from one process to another without occupying floor space.

Warehouses

In warehouses, suspension overhead cranes are used for loading, unloading, stacking, and transferring materials. Their ceiling-mounted structure helps maximize storage space and improve handling efficiency.

Maintenance Areas

Underhung cranes are often installed in equipment maintenance workshops to lift motors, pumps, reducers, machine parts, and other components during repair and replacement operations.

Light Manufacturing Plants

For light manufacturing facilities, underhung overhead cranes provide a compact and practical lifting solution for daily material handling, component transfer, and production support.

Steel Structure and Fabrication Workshops

In fabrication workshops, underhung cranes can be used to lift steel plates, profiles, welded components, and structural parts, especially when the building structure is suitable for suspension crane installation.

Automotive and Parts Production

Underhung crane systems can support automotive parts assembly, mold handling, tool changing, and component transfer along production lines.

Processing Facilities

In processing plants, underhung cranes can help transfer raw materials, semi-finished products, packaging materials, and equipment parts between different working areas.

Frequently Asked Questions About Underhung Overhead Crane

1. What is an underhung overhead crane?

An underhung overhead crane is a type of overhead crane whose bridge girder is suspended from the lower flange of runway beams. The crane travels under the runway structure, which is why it is also called an underslung overhead crane, under running crane, or suspension overhead crane.

2. What is the difference between an underhung overhead crane and a top running overhead crane?

A top running overhead crane runs on rails mounted on top of runway beams, usually supported by columns or building structures. An underhung overhead crane runs on the lower flange of the runway beams and is suspended from the overhead structure.

Underhung cranes are usually more compact and suitable for light to medium-duty applications, while top running cranes are commonly used for heavier lifting capacities and larger spans.

3. When should I choose an underhung overhead crane?

You can choose an underhung overhead crane when:

• Floor space is limited
• Supporting columns are not preferred
• The lifting capacity is light or medium duty
• The workshop has a suitable roof or support structure
• You need a compact lifting system
• The crane is used for assembly, maintenance, warehouse handling, or production support

4. Can an underhung overhead crane be installed in an existing workshop?

Yes. In many cases, an underhung overhead crane can be installed in an existing workshop. However, the building structure must be checked to confirm whether it can support the crane load, hoist load, dynamic load, and runway system. ZOKECRANE can provide technical support based on your workshop drawings.

5. What lifting capacity is available?

Common lifting capacities include 0.5 ton, 1 ton, 2 ton, 3 ton, 5 ton, and 10 ton. Larger capacities may be available depending on structure design and project requirements. The final capacity should be selected according to the actual load and working conditions.

6. What hoist can be used with an underhung crane?

Underhung overhead cranes can be equipped with:

• Electric chain hoist
• Wire rope electric hoist
• Low headroom hoist
• Customized hoist trolley

Electric chain hoists are often used for light-duty applications, while wire rope hoists are suitable for larger capacities and higher lifting heights.

7. Can the crane span and lifting height be customized?

Yes. The span, lifting height, crane traveling length, hoist type, control method, and power supply can all be customized according to customer requirements and workshop conditions.

8. What control methods are available?

Common control methods include pendant control and wireless remote control. For some special applications, the control system can be customized according to the operating process and safety requirements.
