Less expensive. Due to a simpler trolley design, reduced freight costs, simplified and faster installation, and less material for the bridge and runway beams.
Most economical option for light to medium-duty cranes.
Lower loads on the building structure or foundations due to a reduced deadweight. In many cases, it can be supported by existing roof structure without the use of additional support columns.
Better hook approach for both trolley travel and bridge travel.
Easier to install, service, and maintain.
Ideal for workshops, warehouses, material yards, and manufacturing and production facilities.
Lighter load on runway rails or beams means less wear on the beams and end truck wheels over time.
Great for facilities with low headroom.
Transportation: In the transportation industry, underhung bridge cranes assist in unloading ships. They greatly increase the speed of moving and transporting large items.
Concrete Manufacturing: Nearly every product in the concrete industry is large and heavy. Therefore, overhead cranes make everything easier. They handle premixes and preforms efficiently and are much safer than using other types of equipment to move these items.
Metal Refining: Overhead cranes handle raw materials and workpieces through every step of the manufacturing process.
Automotive Manufacturing: Overhead cranes are critical in handling bulky molds, components, and raw materials.
Paper Milling: Underhung bridge cranes are used in paper mills for equipment installation, routine maintenance, and the initial construction of paper machines.
These underhung bridge 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.
Hopefully you have a better sense of whether a top running crane or an under running crane will be the most beneficial for your material handling needs. Under running cranes offer flexibility, functionality, and ergonomic solutions, while top running crane systems offer the advantage of higher capacity lifts and allow for higher lift heights and more overhead room.
