What is An Underhung Bridge Crane?

Underhung bridge crane, underhung overhead travelling crane, also be named under running overhead crane. Even buildings without preparation for a runway beam (e.g., non-load-bearing building supports) can be equipped with an overhead bridge crane. An underslung travelling crane is exactly the right thing for such building conditions. Underhung overhead travelling cranes can allow you to maximize your facility's floor space for production and storage of material because they are most commonly supported from the existing ceiling trusses or the roof structure. Underhung cranes also offer excellent side approach and maximize utilization of the building's width and height when supported by roof or ceiling structures. They're ideal for facilities that lack vertical clearance to install a top-running overhead crane system. The underslung travelling cranes offer load capacities of up to 10 tons.

Under running cranes are most commonly configured in a single girder design for lighter service and lower-capacity applications, as they are supported from the existing ceiling trusses or the roof structure. The lifting height and hook height of underhung bridge cranes is less than that of top running cranes.

An under running single girder crane will utilize an under running hoist and trolley which moves across the bottom flange of the bridge beam. A double girder under running crane can run its hoist and trolley along the top or the bottom of the bridge beams.

If the building's existing support structure can’t be utilized, under running cranes can be designed in a free-standing configuration, but this setup does require the use of support or mounting columns.

In addition, the underhung bridge cranes can also be designed as a telescopic structure (telescopic underhung cranes). This design can effectively improve the working range of the under running overhead crane. For example, this design solution allows you to extend the crane's extension arm out of the window to lift heavy objects outside the house through the window.

Benefits of an Under Running Overhead Crane

• Lifting Capacity: 0.5 to 10 tons
• Span: Under 65 feet
• Power Supply: 220 – 550V 3Phase 50/60Hz
• Working Duty: Light to medium duty
• Common Applications: Assembly, fabrication shops, maintenance buildings, and manufacturing facilities
• Maximizes floor space if supported by existing ceiling trusses or roof structure
• Reduces material costs if no runway support columns are needed
• Increased end hook approach and bridge beam and hoist are underneath runway beams

Other Points You Should Know About Underhung Bridge Cranes

Compared with top running cranes, when it comes to the installation and service of an under running crane system, it can be more of a complex procedure leading to longer downtime. Because the crane is suspended from the runways, it can take longer to check the alignment or service the wheels of the crane, but it is easier to dial in and maintain the alignment and there are fewer tracking problems because it runs on an I-beam which is secured to building structure - limiting movement.

Application of Underhung Bridge Crane

Underhung bridge cranes are widely used in parts assembly, manufacturing and processing, pallet loading, injection molding, warehousing loading and unloading, and equipment maintenance due to their light lifting capacity.
