An underhung monorail crane is a type of overhead crane designed to operate on a single rail or beam, which is typically suspended from the ceiling of a facility. The term "underhung" refers to the fact that the crane's trolley, which houses the hoist, travels underneath the rail or beam rather than on top of it.
Underhung monorail cranes are used to transport materials along a fixed path in a linear or curved pattern within a facility. They are typically used for applications where materials need to be moved across a specific path consistently and efficiently, such as assembly lines, painting or finishing processes, or warehousing applications.
Sinoko European underhung monorail cranes is designed with a focus on efficiency, compactness, and energy conservation. Its unique design concept makes it smaller in size, lighter in weight, and exerts less wheel pressure compared to traditional cranes. This design also ensures a smaller distance between the hook and the wall, allowing the crane to operate closer to the front and providing a higher lifting height.
1. Mechanical parts
Single main beam, welded box, the arch in line with national standards.
The steel sheet material is Q235B or Q345B.
The web plate is cut by 40m CNC machine cutting to ensure smooth molding and precision of the crown curve.
The main weld with submerged arc welding, non-destructive testing.
After welding the whole beam shot blasting treatment, to Sa2.5 level, to eliminate welding stress.
Epoxy zinc-rich paint, two bottom two sides, 140μ thick, long life, beautiful appearance, good gloss.
The main beam and the end beam are connected with 10.9 high strength bolts to ensure the strength and precision of the whole structure.
The long travelling and trolley are all use three-in-one drive mechanism, variable frequency stepless speed, hardened surface, disc brakes.
Long travelling level IP55, F-class insulation, power transfer rate of 40% ED.
End beam configuration flat wheel or double wheel rim wheel, anti-wear bearing, cart buffer block, anti-derailment end plate.
2. Electric Parts
Long travelling, cross travelling and lifting hoist are Independent operation, can run alone or at the same time.
Electronic control box anti-corrosion, protection class to IP55.All connections are reloaded with aviation plugs and sockets, sealed and fastened
Control box layout reasonable, easy to repair
Plug connection with plastic casing insulation protection
