An underhung bridge crane, also known as an under running overhead crane or underslung travelling crane, is a type of lifting system that is suspended from the building’s roof structure or ceiling trusses rather than supported from the ground. This design makes it an ideal solution for facilities that were not originally constructed with runway beams or heavy load-bearing columns. Even in buildings with limited structural preparation, an underhung crane can be installed efficiently by utilizing the existing roof framework.
One of the main advantages of this crane type is its ability to maximize floor space utilization. Since the system is mounted overhead, it frees up valuable ground area for production, storage, or other operations. Additionally, underhung cranes provide excellent side approach, allowing operators to make full use of the building’s width and height. They are particularly suitable for workshops or warehouses with restricted vertical clearance, where installing a top-running crane would not be feasible. Typically, these cranes are designed for light to medium-duty applications, with lifting capacities of up to 10 tons.
Under running cranes are most commonly designed as single girder systems, offering a cost-effective and lightweight solution for everyday material handling tasks. Due to their suspension structure, the lifting and hook height is generally lower compared to top-running cranes. The hoist and trolley in a single girder configuration travel along the bottom flange of the bridge beam, ensuring smooth and stable operation.
Key Features of Underhung Bridge Crane
Space-Saving Ceiling-Mounted Design
The underhung configuration allows the crane to run on tracks mounted directly to the building roof structure. This design eliminates the need for floor-mounted rails and maximizes usable workspace below. It is especially suitable for facilities with limited headroom or restricted vertical clearance, making full use of available space.
Efficient Handling for Light to Medium Loads
Designed for applications ranging from 1 ton to 10 tons, this underhung bridge crane is ideal for warehouses, workshops, and assembly lines. It provides reliable and efficient material handling, improving workflow and reducing manual labor.
Smooth and Low-Noise Operation
Equipped with precision-engineered wheels, bearings, and drive systems, the crane ensures smooth travel and stable lifting. The low-noise operation creates a more comfortable working environment, particularly important for indoor facilities.
Robust End Trucks for Stability
The underhung bridge crane features heavy-duty end trucks that deliver stable movement along the runway. Even under full load, the system maintains balance and safety, reducing wear and extending the service life of the equipment.
Quick and Cost-Effective Installation
Thanks to its simplified structure, the underhung crane is easy to install and requires less installation time compared to traditional top-running systems. This helps reduce initial setup costs and minimizes disruption to ongoing operations.
Flexible Customization Options
The underhung bridge crane can be tailored to specific project requirements, including span length, lifting height, control methods (pendant or remote), and speed configurations. This adaptability ensures it meets a wide range of operational needs.
Durable Construction with Safety Features
Manufactured from high-strength steel, the crane is built for durability in demanding environments. Integrated safety features such as overload protection, limit switches, and emergency stop systems ensure safe and reliable operation.
Energy-Efficient Performance
Optimized drive systems and efficient components help reduce energy consumption, lowering operating costs while supporting environmentally friendly operations.
